In this article, we present results from an interdisciplinary research project aimed at assessing consciousness in dreams. For this purpose, we compared lucid dreams with normal non-lucid dreams from REM sleep. Both lucid and non-lucid dreams are an important contrast condition for theories of waking consciousness, giving valuable insights into the structure of conscious experience and its neural correlates during sleep. However, the precise differences between lucid and non-lucid dreams remain poorly understood. The construction of the Lucidity and Consciousness in Dreams scale (LuCiD) was based on theoretical considerations and empirical observations. Exploratory factor analysis of the data from the first survey identified eight factors that were validated in a second survey using confirmatory factor analysis: INSIGHT, CONTROL, THOUGHT, REALISM, MEMORY, DISSOCIATION, NEGATIVE EMOTION, and POSITIVE EMOTION. While all factors are involved in dream consciousness, realism and negative emotion do not differentiate between lucid and non-lucid dreams, suggesting that lucid insight is separable from both bizarreness in dreams and a change in the subjectively experienced realism of the dream.

Is dream recall underestimated by retrospective measures and enhanced by keeping a logbook? A review.

PubMed

Aspy, Denholm J; Delfabbro, Paul; Proeve, Michael

2015-05-01

There are two methods commonly used to measure dream recall in the home setting. The retrospective method involves asking participants to estimate their dream recall in response to a single question and the logbook method involves keeping a daily record of one's dream recall. Until recently, the implicit assumption has been that these measures are largely equivalent. However, this is challenged by the tendency for retrospective measures to yield significantly lower dream recall rates than logbooks. A common explanation for this is that retrospective measures underestimate dream recall. Another is that keeping a logbook enhances it. If retrospective measures underestimate dream recall and if logbooks enhance it they are both unlikely to reflect typical dream recall rates and may be confounded with variables associated with the underestimation and enhancement effects. To date, this issue has received insufficient attention. The present review addresses this gap in the literature. Copyright © 2015 Elsevier Inc. All rights reserved.

REM Sleep Behavioral Events and Dreaming

Muntean, Maria-Lucia; Trenkwalder, Claudia; Walters, Arthur S.; Mollenhauer, Brit; Sixel-Döring, Friederike

Study Objectives: To clarify whether motor behaviors and/ or vocalizations during REM sleep, which do not yet fulfill diagnostic criteria for REM sleep behavior disorder (RBD) and were defined as REM sleep behavioral events (RBEs), correspond to dream enactments. Methods: 13 subjects (10 patients with Parkinson disease [PD] and 3 healthy controls) originally identified with RBE in a prospective study (DeNoPa cohort) were reinvestigated 2 years later with 2 nights of video-supported polysomnography (vPSG). The first night was used for sleep parameter analysis. During the 2nd night, subjects were awakened and questioned for dream recall and dream content when purposeful motor behaviors and/or vocalizations became evident during REM sleep. REM sleep without atonia (RWA) was analyzed on chin EMG and the cutoff set at 18.2% as specific for RBD. Results: At the time of this investigation 9 of 13 subjects with previous RBE were identified with RBD based upon clinical and EMG criteria. All recalled vivid dreams, and 7 subjects were able to describe dream content in detail. Four of 13 subjects with RBE showed RWA values below cutoff values for RBD. Three of these 4 subjects recalled having non-threatening dreams, and 2 (of these 3) were able to describe these dreams in detail. Conclusion: RBE with RWA below the RBD defining criteria correlate to dreaming in this selected cohort. There is evidence that RBEs are a precursor to RBD.

The interpretation of dream meaning: Resolving ambiguity using Latent Semantic Analysis in a small corpus of text.

Computer-based dreams content analysis relies on word frequencies within predefined categories in order to identify different elements in text. As a complementary approach, we explored the capabilities and limitations of word-embedding techniques to identify word usage patterns among dream reports. These tools allow us to quantify words associations in text and to identify the meaning of target words. Word-embeddings have been extensively studied in large datasets, but only a few studies analyze semantic representations in small corpora. To fill this gap, we compared Skip-gram and Latent Semantic Analysis (LSA) capabilities to extract semantic associations from dream reports. LSA showed better performance than Skip-gram in small size corpora in two tests. Furthermore, LSA captured relevant word associations in dream collection, even in cases with low-frequency words or small numbers of dreams. Word associations in dreams reports can thus be quantified by LSA, which opens new avenues for dream interpretation and decoding. Copyright © 2017 Elsevier Inc. All rights reserved.

Lucid dreaming verified by volitional communication during REM sleep.

PubMed

La Berge, S P; Nagel, L E; Dement, W C; Zarcone, V P

1981-06-01

The occurrence of lucid dreaming (dreaming while being conscious that one is dreaming) has been verified for 5 selected subjects who signaled that they knew they were dreaming while continuing to dream during unequivocal REM sleep. The signals consisted of particular dream actions having observable concomitants and were performed in accordance with pre-sleep agreement. The ability of proficient lucid dreamers to signal in this manner makes possible a new approach to dream research--such subjects, while lucid, could carry out diverse dream experiments marking the exact time of particular dream events, allowing derivation of of precise psychophysiological correlations and methodical testing of hypotheses.

Dreaming and Neuroesthetics

This paper, which is limited to the art of painting, aims to support the idea that a substantial insertion of concepts and methods drawn on dream psychology and dream neuroscience can contribute to the advancements of Neuroesthetics. The historical and scientific reasons are discussed that have determined the so far poor role played by the dream phenomenon in the developments of Neuroesthetics. In the light of recent advancements in psychophysiological research, a method of analyzing artistic products is proposed that is based on the recognition of precise features proper of the dreaming experience. Four examples are given for application of this method, regarding works by Giorgione, Leonardo da Vinci, Vermeer, and Millais, respectively. PMID:26157373

Dream recall and dream content in obsessive-compulsive patients: is there a change during exposure treatment?

PubMed

Kuelz, Anne K; Stotz, Ulrike; Riemann, Dieter; Schredl, Michael; Voderholzer, Ulrich

2010-08-01

Very little is known about dreams in patients with obsessive compulsive disorder, especially regarding changes over the course of treatment with stimulus exposure and response prevention. By use of dream content analysis, 40 dreams of 9 obsessive compulsive (OC) inpatients were compared with 84 dreams of 10 matched OC outpatients and 63 dreams of 11 healthy control participants. Dream protocols of inpatients were collected at the beginning of treatment and after the first exposure exercises. Controls filled in dream protocols in respective intervals. Before treatment, dreams of patients showed significantly less positive contents than dreams of healthy controls. Under treatment with exposure, a significant reduction of OC themes was observed. The findings support the continuity hypothesis of dreaming by showing a link between day-time symptoms and OC symptoms in dreams. Contrary to expectations, however, exposure treatment does not intensify dreams.

How to test the threat-simulation theory.

Malcolm-Smith, Solms, Turnbull and Tredoux [Malcolm-Smith, S., Solms, M.,Turnbull, O., & Tredoux, C. (2008). Threat in dreams: An adaptation? Consciousness and Cognition, 17, 1281-1291.] have made an attempt to test the Threat-Simulation Theory (TST), a theory offering an evolutionary psychological explanation for the function of dreaming [Revonsuo, A. (2000a). The reinterpretation of dreams: An evolutionary hypothesis of the function of dreaming. Behavioral and Brain Sciences, 23(6), 877-901]. Malcolm-Smith et al. argue that empirical evidence from their own study as well as from some other studies in the literature does not support the main predictions of the TST: that threatening events are frequent and overrepresented in dreams, that exposure to real threats activates the threat-simulation system, and that dream threats contain realistic rehearsals of threat avoidance responses. Other studies, including our own, have come up with results and conclusions that are in conflict with those of Malcolm-Smith et al. In this commentary, we provide an analysis of the sources of these disagreements, and their implications to the TST. Much of the disagreement seems to stem from differing interpretations of the theory and, consequently, of differing methods to test it.

What I make up when I wake up: anti-experience views and narrative fabrication of dreams.

PubMed

Rosen, Melanie G

2013-01-01

I propose a narrative fabrication thesis of dream reports, according to which dream reports are often not accurate representations of experiences that occur during sleep. I begin with an overview of anti-experience theses of Norman Malcolm and Daniel Dennett who reject the received view of dreams, that dreams are experiences we have during sleep which are reported upon waking. Although rejection of the first claim of the received view, that dreams are experiences that occur during sleep, is implausible, I evaluate in more detail the second assumption of the received view, that dream reports are generally accurate. I then propose a "narrative fabrication" view of dreams as an alternative to the received view. Dream reports are often confabulated or fabricated because of poor memory, bizarre dream content, and cognitive deficits. It is well documented that narratives can be altered between initial rapid eye movement sleep awakenings and subsequent reports. I argue that we have reason to suspect that initial reports are prone to inaccuracy. Experiments demonstrate that subjects rationalize strange elements in narratives, leaving out supernatural or bizarre components when reporting waking memories of stories. Inaccuracies in dream reports are exacerbated by rapid memory loss and bizarre dream content. Waking memory is a process of reconstruction and blending of elements, but unlike waking memory, we cannot reality-test for dream memories. Dream experiences involve imaginative elements, and dream content cannot be verified with external evidence. Some dreams may involve wake-like higher cognitive functions, such as lucid dreams. Such dreams are more likely to elicit accurate reports than cognitively deficient dreams. However, dream reports are generally less accurate than waking reports. I then propose methods which could verify the narrative fabrication view, and argue that although the theory cannot be tested with current methods, new techniques and technologies may be able to do so in the future.

[Reconsidering children's dreams. A critical review of methods and results in developmental dream research from Freud to contemporary works].

PubMed

Sándor, Piroska; Bódizs, Róbert

2014-01-01

Examining children's dream development is a significant challenge for researchers. Results from studies on children's dreaming may enlighten us on the nature and role of dreaming as well as broaden our knowledge of consciousness and cognitive development. This review summarizes the main questions and historical progress in developmental dream research, with the aim of shedding light on the advantages, disadvantages and effects of different settings and methods on research outcomes. A typical example would be the dreams of 3 to 5 year-olds: they are simple and static, with a relative absence of emotions and active self participation according to laboratory studies; studies using different methodology however found them to be vivid, rich in emotions, with the self as an active participant. Questions about the validity of different methods arise, and are considered within this review. Given that methodological differences can result in highly divergent outcomes, it is strongly recommended for future research to select methodology and treat results more carefully.

Dream analysis in the psychodynamic psychotherapy of borderline patients.

2012-06-01

Despite Freud's dictum that dreams are the royal road to the unconscious, the use of dream analysis by therapists working with Borderline Personality Disorder and other severe psychiatric conditions has in the past two decades has fallen into a state of decline, if not outright neglect. The reasons why are not altogether clear, though some have said that the growing popularity of ego psychology and other movements in the domain of psychoanalysis have perhaps pushed dream analysis to one side. To me this marginalization seems unjustified. I hope to demonstrate in this article the enduring utility of dream analysis in working with the more severely disordered patients, with the aim of revivifying its application--and its efficacy--in our work with such patients.

Social dreaming: competition or complementation to individual dreaming?

Social dreaming is presented as a method to explore the unconscious dimension of the social world. The theoretical position of social dreaming and its historical development is described. Two examples are given for the practical application of social dreaming, a professional meeting of psychotherapists and an experiential workshop dealing with the aftermath of trauma. It is suggested that social dreaming is complementary to individual dreaming and offers insights and explanations, as well as guidance on various levels for applications in clinical, organizational, institutional and social settings. © 2010, The Society of Analytical Psychology.

Analytic process and dreaming about analysis.

PubMed

Sirois, François

2016-12-01

Dreams about the analytic session feature a manifest content in which the analytic setting is subject to distortion while the analyst appears undisguised. Such dreams are a consistent yet infrequent occurrence in most analyses. Their specificity consists in never reproducing the material conditions of the analysis as such. This paper puts forward the following hypothesis: dreams about the session relate to some aspects of the analyst's activity. In this sense, such dreams are indicative of the transference neurosis, prefiguring transference resistances to the analytic elaboration of key conflicts. The parts taken by the patient and by the analyst are discussed in terms of their ability to signal a deepening of the analysis. Copyright © 2016 Institute of Psychoanalysis.

The examination of children's sleep-related mental experiences presents many significant challenges for researchers investigating the developmental trajectories of human dreaming. In contrast to the well-explored developmental patterns of human sleep, data from dream research are strikingly divergent with highly ambiguous results and conclusions, even though there is plenty of indirect evidence suggesting parallel patterns of development between neural maturation and dreaming. Thus results from studies of children's dreaming are of essential importance not only to enlighten us on the nature and role of dreaming but to also add to our knowledge of consciousness and cognitive and emotional development. This review summarizes research results related to the ontogeny of dreaming: we critically reconsider the field, systematically compare the findings based on different methodologies, and highlight the advantages and disadvantages of methods, arguing in favor of methodological pluralism. Since most contradictory results emerge in connection with descriptive as well as content related characteristics of young children's dreams, we emphasize the importance of carefully selected dream collection methods. In contrast nightmare-related studies yield surprisingly convergent results, thus providing strong basis for inferences about the connections between dreaming and cognitive emotional functioning. Potential directions for dream research are discussed, aiming to explore the as yet unraveled correlations between the maturation of neural organization, sleep architecture and dreaming patterns.

In No. 8, 48th year, August 1998, of the journal "Psychotherapie--Psychosomatik--Medizinische Psychologie" the tape recorder transcription of the 290th session of a long-term analysis was studied by three methods (BIP, Frames, ZBKT). The paper presented here was stimulated by this publication. From the author's viewpoint substantial clinical aspects of evaluation could be added by applying a clinical evaluation method developed by R. Langs and his corresponding concept of interpretation. Clinical vignettes exemplify the possibility to resolve pathological countertransference by using this evaluation method. With the help of this method the presented transcription of the 290th session is evaluated partially.

Lucid Dreaming in Narcolepsy

2015-01-01

Objective: To evaluate the frequency, determinants and sleep characteristics of lucid dreaming in narcolepsy Settings: University hospital sleep disorder unit Design: Case-control study Participants: Consecutive patients with narcolepsy and healthy controls Methods: Participants were interviewed regarding the frequency and determinants of lucid dreaming. Twelve narcolepsy patients and 5 controls who self-identified as frequent lucid dreamers underwent nighttime and daytime sleep monitoring after being given instructions regarding how to give an eye signal when lucid. Results: Compared to 53 healthy controls, the 53 narcolepsy patients reported more frequent dream recall, nightmares and recurrent dreams. Lucid dreaming was achieved by 77.4% of narcoleptic patients and 49.1% of controls (P < 0.05), with an average of 7.6 ± 11 vs. 0.3 ± 0.8 lucid dreams/month (P < 0.0001). The frequency of cataplexy, hallucinations, sleep paralysis, dyssomnia, HLA positivity, and the severity of sleepiness were similar in narcolepsy with and without lucid dreaming. Seven of 12 narcoleptic (and 0 non-narcoleptic) lucid dreamers achieved lucid REM sleep across a total of 33 naps, including 14 episodes with eye signal. The delta power in the electrode average, in delta, theta, and alpha powers in C4, and coherences between frontal electrodes were lower in lucid than non-lucid REM sleep in spectral EEG analysis. The duration of REM sleep was longer, the REM sleep onset latency tended to be shorter, and the percentage of atonia tended to be higher in lucid vs. non-lucid REM sleep; the arousal index and REM density and amplitude were unchanged. Conclusion: Narcoleptics have a high propensity for lucid dreaming without differing in REM sleep characteristics from people without narcolepsy. This suggests narcolepsy patients may provide useful information in future studies on the nature of lucid dreaming. Citation: Dodet P, Chavez M, Leu-Semenescu S, Golmard JL, Arnulf I.

2014-01-01

Study Objectives: To conduct a comprehensive and comparative study of prospectively collected bad dream and nightmare reports using a broad range of dream content variables. Design: Correlational and descriptive. Setting: Participants' homes. Participants: Three hundred thirty-one adult volunteers (55 men, 275 women, 1 not specified; mean age = 32.4 ± 14.8 y). Interventions: N/A. Measurement and Results: Five hundred seventy-two participants kept a written record of all of their remembered dreams in a log for 2 to 5 consecutive weeks. A total of 9,796 dream reports were collected and the content of 253 nightmares and 431 bad dreams reported by 331 participants was investigated. Physical aggression was the most frequently reported theme in nightmares, whereas interpersonal conflicts predominated in bad dreams. Nightmares were rated by participants as being substantially more emotionally intense than were bad dreams. Thirty-five percent of nightmares and 55% of bad dreams contained primary emotions other than fear. When compared to bad dreams, nightmares were more bizarre and contained substantially more aggressions, failures, and unfortunate endings. Conclusions: The results have important implications on how nightmares are conceptualized and defined and support the view that when compared to bad dreams, nightmares represent a somewhat rarer—and more severe—expression of the same basic phenomenon.

On talking-as-dreaming.

PubMed

Ogden, Thomas H

2007-06-01

Many patients are unable to engage in waking-dreaming in the analytic setting in the form of free association or in any other form. The author has found that "talking-as-dreaming" has served as a form of waking-dreaming in which such patients have been able to begin to dream formerly undreamable experience. Such talking is a loosely structured form of conversation between patient and analyst that is often marked by primary process thinking and apparent non sequiturs. Talking-as-dreaming superficially appears to be "unanalytic" in that it may seem to consist "merely" of talking about such topics as books, films, etymology, baseball, the taste of chocolate, the structure of light, and so on. When an analysis is "a going concern," talking-as-dreaming moves unobtrusively into and out of talking about dreaming. The author provides two detailed clinical examples of analytic work with patients who had very little capacity to dream in the analytic setting. In the first clinical example, talking-as-dreaming served as a form of thinking and relating in which the patient was able for the first time to dream her own (and, in a sense, her father's) formerly unthinkable, undreamable experience. The second clinical example involves the use of talking-as-dreaming as an emotional experience in which the formerly "invisible" patient was able to begin to dream himself into existence. The analyst, while engaging with a patient in talking-as-dreaming, must remain keenly aware that it is critical that the difference in roles of patient and analyst be a continuously felt presence; that the therapeutic goals of analysis be firmly held in mind; and that the patient be given the opportunity to dream himself into existence (as opposed to being dreamt up by the analyst).

Genome wide analysis of DNA methylation provides important information in a variety of diseases, including cancer. Here, we describe a simple method, Digital Restriction Enzyme Analysis of Methylation (DREAM), based on next generation sequencing analysis of methylation-specific signatures created by sequential digestion of genomic DNA with SmaI and XmaI enzymes. DREAM provides information on 150,000 unique CpG sites, of which 39,000 are in CpG islands and 30,000 are at transcription start sites of 13,000 RefSeq genes. We analyzed DNA methylation in healthy white blood cells and found methylation patterns to be remarkably uniform. Inter individual differences > 30% were observed only at 227 of 28,331 (0.8%) of autosomal CpG sites. Similarly, > 30% differences were observed at only 59 sites when we comparing the cord and adult blood. These conserved methylation patterns contrasted with extensive changes affecting 18–40% of CpG sites in a patient with acute myeloid leukemia and in two leukemia cell lines. The method is cost effective, quantitative (r2 = 0.93 when compared with bisulfite pyrosequencing) and reproducible (r2 = 0.997). Using 100-fold coverage, DREAM can detect differences in methylation greater than 10% or 30% with a false positive rate below 0.05 or 0.001, respectively. DREAM can be useful in quantifying epigenetic effects of environment and nutrition, correlating developmental epigenetic variation with phenotypes, understanding epigenetics of cancer and chronic diseases, measuring the effects of drugs on DNA methylation or deriving new biological insights into mammalian genomes.

Trauma, dream, and psychic change in psychoanalyses: a dialog between psychoanalysis and the neurosciences.

To many psychoanalysts dreams are a central source of knowledge of the unconscious-the specific research object of psychoanalysis. The dialog with the neurosciences, devoted to the testing of hypotheses on human behavior and neurophysiology with objective methods, has added to psychoanalytic conceptualizations on emotion, memory, sleep and dreams, conflict and trauma. To psychoanalysts as well as neuroscientists, the neurological basis of psychic functioning, particularly concerning trauma, is of special interest. In this article, an attempt is made to bridge the gap between psychoanalytic findings and neuroscientific findings on trauma. We then attempt to merge both approaches in one experimental study devoted to the investigation of the neurophysiological changes (fMRI) associated with psychoanalytic treatment in chronically depressed patients. We also report on an attempt to quantify psychoanalysis-induced transformation in the manifest content of dreams. To do so, we used two independent methods. First, dreams reported during the cure of chronic depressed analysands were assessed by the treating psychoanalyst. Second, dreams reported in an experimental context were analyzed by an independent evaluator using a standardized method to quantify changes in dream content (Moser method). Single cases are presented. Preliminary results suggest that psychoanalysis-induced transformation can be assessed in an objective way.

Early psychiatry investigated dreams to understand psychopathologies. Contemporary psychiatry, which neglects dreams, has been criticized for lack of objectivity. In search of quantitative insight into the structure of psychotic speech, we investigated speech graph attributes (SGA) in patients with schizophrenia, bipolar disorder type I, and non-psychotic controls as they reported waking and dream contents. Schizophrenic subjects spoke with reduced connectivity, in tight correlation with negative and cognitive symptoms measured by standard psychometric scales. Bipolar and control subjects were undistinguishable by waking reports, but in dream reports bipolar subjects showed significantly less connectivity. Dream-related SGA outperformed psychometric scores or waking-related data for group sorting. Altogether, the results indicate that online and offline processing, the two most fundamental modes of brain operation, produce nearly opposite effects on recollections: While dreaming exposes differences in the mnemonic records across individuals, waking dampens distinctions. The results also demonstrate the feasibility of the differential diagnosis of psychosis based on the analysis of dream graphs, pointing to a fast, low-cost and language-invariant tool for psychiatric diagnosis and the objective search for biomarkers. The Freudian notion that "dreams are the royal road to the unconscious" is clinically useful, after all.

Schizophrenic subjects spoke with reduced connectivity, in tight correlation with negative and cognitive symptoms measured by standard psychometric scales. Bipolar and control subjects were undistinguishable by waking reports, but in dream reports bipolar subjects showed significantly less connectivity. Dream-related SGA outperformed psychometric scores or waking-related data for group sorting. Altogether, the results indicate that online and offline processing, the two most fundamental modes of brain operation, produce nearly opposite effects on recollections: While dreaming exposes differences in the mnemonic records across individuals, waking dampens distinctions. The results also demonstrate the feasibility of the differential diagnosis of psychosis based on the analysis of dream graphs, pointing to a fast, low-cost and language-invariant tool for psychiatric diagnosis and the objective search for biomarkers. The Freudian notion that “dreams are the royal road to the unconscious” is clinically useful, after all. PMID:24424108

Psychodynamic Interpretations of the Immigrant's Dream: Comments on Adler's (1993) "Refugee Dreams and Attachment Theory."

There is ongoing debate on whether the full moon is associated with sleep and dreaming. The analysis of diaries kept by the participants (N = 196) over 28 to 111 nights showed no association of a full moon and dream recall. Psychological factors might explain why some persons associate a full moon with increased dream recall.

The Dream Interview Method is a recently developed tool for dream interpretation that can facilitate work on addiction issues at all stages of recovery. This paper describes the method in detail and discusses examples of its application in a group composed of individuals in varying stages of the recovery process. It permits the therapist to accelerate the development of insight, and once the method is learned, it can be applied in self-help formats.

Analysis of the dream contents in Japanese college students by REMP-awakening technique.

Yamanaka, T; Morita, Y; Matsumoto, J

1982-01-01

An experiment was performed on 39 college students aged from 19 to 21 years using the REMP-awakening technique. The contents of 297 dreams were analyzed according to the Hall-Van de Castle scale. The recall rate was 76% (home) and 85.5% (laboratory). The dream with past experiences was 75% (home), 64.9% (laboratory) and the bizarre dream was 30.5% (home), 28.8% (laboratory) and the dream experiment was 3.6% (home) and 11.7% (laboratory). Emotional and color dreams were noted more in females than in males. Female dreamers tended to be the victim of aggressive dreams as compared with the males. In our student dreams, there were more characters and they dreamed more about food and less about movement activity than in the American students of Hall & Van de Castle. From the polygraphic records, the relation between verbal activity and submental EMG activity, the pulse rate variability and emotionality in dreams, the number of reported dreams and the amount of body movement, eye movement density and the vividness of dream contents were revealed.

Older people's experiences of dream coaching.

PubMed

Wadensten, Barbro

2009-12-01

Recalling and talking about dreams could initiate dream work among older people and provide an opportunity for self-confrontation and personal growth, which could in turn promote gerotranscendental development. The present article describes older people's opinions about participating in a dream-coaching group; it also briefly describes the theoretical foundation of dream coaching. The study aim was to investigate older people's experience of participating in a dream-coaching group based on Jungian psychology. A descriptive design was used. Retrospective interviews were explored using qualitative content analysis. The participants were satisfied with the arrangement of the dream-coaching groups. All participants believed that they had recalled their dreams and thought much more about their dreams during the period in which the dream-coaching group met. Three diverse appraisals of participating in a dream-coaching group, which had different effects on the participants, were identified: "An activity like any other activity," "An activity that led to deeper thoughts about the meaning of dreams," and "An activity that led to deeper thoughts both about the meaning of dreams and about how dreams can improve one's understanding of the life situation." It is possible to arrange dream-coaching groups for older people and could be a way to promote personal development using this type of intervention. The study provides some guidance as to how such a group could be organized, thus facilitating use of dream-coaching groups in gerontological care.

Absorption, psychological boundaries and attitude towards dreams as correlates of dream recall: two decades of research seen through a meta-analysis.

PubMed

Beaulieu-Prévost, Dominic; Zadra, Antonio

2007-03-01

Many studies have reported positive correlations between dream recall frequency (DRF) and measures of absorption, psychological boundaries and attitude towards dreams. A majority of these studies, however, have relied exclusively on retrospective measures of DRF even though daily dream logs are generally considered to be more direct and valid measures of DRF. The first goal of the present meta-analysis was to evaluate the effect sizes of three variables (absorption, psychological boundaries and attitude towards dreams) as correlates of DRF. The second goal was to evaluate if these effect sizes varied as a function of how DRF was operationalized (i.e. retrospective measure versus dream log). Data from 24 studies were included in the analyses. For each of the three variables investigated, correlations with retrospective measures of DRF were of greater magnitude than those obtained with daily logs. These results indicate that scores on measures of absorption and psychological boundaries are not related to DRF per se, but rather to people's tendency to retrospectively underestimate or overestimate their DRF, while attitude towards dreams is related both to DRF per se and to people's retrospective estimation bias. Implications of these findings for dream research are discussed.

Objective. Violent dream content and its acting out during rapid eye movement sleep are considered distinctive for rapid eye movement sleep behaviour disorder (RBD). This study reports first quantitative data on dreaming in a cohort of patients with treated Wilson's disease (WD) and in patients with WD with RBD. Methods. Retrospective questionnaires on different dimensions of dreaming and a prospective two-week home dream diary with self-rating of emotions and blinded, categorical rating of content by an external judge. Results. WD patients showed a significantly lower dream word count and very few other differences in dream characteristics compared to age- and sex-matched healthy controls. Compared to WD patients without RBD, patients with WD and RBD reported significantly higher nightmare frequencies and more dreams with violent or aggressive content retrospectively; their prospectively collected dream reports contained significantly more negative emotions and aggression. Conclusions. The reduction in dream length might reflect specific cognitive deficits in WD. The lack of differences regarding dream content might be explained by the established successful WD treatment. RBD in WD had a strong impact on dreaming. In accordance with the current definition of RBD, violent, aggressive dream content seems to be a characteristic of RBD also in WD.

Images evoked immediately before the induction of anesthesia with the help of suggestions may influence dreaming during anesthesia.The aim of the study was to assess the incidence of evoked dreams and dream recalls by employing suggestions before induction of anesthesia while administering different general anesthetic combinations. This is a single center, prospective randomized including 270 adult patients scheduled for maxillofacial surgical interventions. Patients were assigned to control, suggestion and dreamfilm groups according to the psychological method used. According to the anesthetic protocol there were also three subgroups: etomidate & sevoflurane, propofol & sevoflurane, propofol & propofol groups. Primary outcome measure was the incidence of postoperative dreams in the non-intervention group and in the three groups receiving different psychological interventions. Secondary endpoint was to test the effect of perioperative suggestions and dreamfilm-formation training on the occurrance of dreams and recallable dreams in different general anesthesiological techniques. Dream incidence rates measured in the control group did not differ significantly (etomidate & sevoflurane: 40%, propofol & sevoflurane: 26%, propofol & propofol: 39%). A significant increase could be observed in the incidence rate of dreams between the control and suggestion groups in the propofol & sevoflurane (26%-52%) group (p = 0.023). There was a significant difference in the incidence of dreams between the control and dreamfilm subgroup in the propofol & sevoflurane (26% vs. 57%), and in the propofol & propofol group (39% vs.70%) (p = 0.010, and p = 0.009, respectively). Similar to this, there was a significant difference in dream incidence between the dreamfilm and the suggestion subgroups (44% vs. 70%) in the propofol & propofol group (p = 0.019). Propofol as an induction agent contributed most to dream formation and recalls (χ2-test p value: 0.005). The content of images and dreams evoked using suggestions showed great agreement using all three anesthetic protocols. The psychological method influenced dreaming during anesthesia. The increase of the incidence rate of dreams was dependent on the anesthetic agent used, especially the induction agent. The study was registered in ClinicalTrials.gov. Identifier: NCT01839201.

The fate of the dream in contemporary psychoanalysis.

PubMed

Loden, Susan

2003-01-01

Freud's metapsychology of dream formation has implicitly been discarded, as indicated in a brief review of trends in psychoanalytic thinking about dreams, with a focus on the relationship of the dream process to ego capacities. The current bias toward exclusive emphasis on the exploration of the analytic relationship and the transference has evolved at the expense of classical, in-depth dream interpretation, and, by extension, at the expense of strengthening the patient's capacity for self-inquiry. This trend is shown to be especially evident in the treatment of borderline patients, who today are believed by many analysts to misuse the dream in the analytic situation. An extended clinical example of a borderline patient with whom an unmodified Freudian associative technique of dream interpretation is used with good outcome illustrates the author's contrary conviction. In clinical practice, we should neglect neither the uniqueness of the dream as a central intrapsychic event nor the Freudian art of total dream analysis.

Dream recall frequency and content in patients with temporal lobe epilepsy.

To evaluate morning dream recall frequency and content in patients with temporal lobe epilepsy (TLE). Fifty-two patients with pharmacoresistant TLE submitted to a written dream diary during five consecutive days and continuous video-electroencephalographic (video-EEG) monitoring. A matched control group of 41 healthy subjects completed the same diary at home. The number of recalled dreams (including long dreams) and nonrecalled dream mentation were collected, and the Dream Recall Rate (DRR) was calculated. Hall and Van de Castle dream content analysis was performed. Greater than 70% of patients with TLE (37 of 52) recall their dreams, but DRR rate in these patients is lower than in controls (p ≤ 0.001). Dream recall does not appear to be influenced by the presence of neuropsychological deficits nor seizure frequency. In dreams descriptions, TLE patients (vs. controls) have a higher percentage of familiarity in settings and fewer dreams with at least one success. Onirical activity of patients with TLE is different from that of healthy subjects. Our results support the role of mesial and neocortical temporal structures in dream experience. The selective activation of dysfunctional mesial structures may be responsible for some of the observed variability. However, dream content changes can also mirror social and psychological comorbidities of patients with epilepsy. Wiley Periodicals, Inc. © 2011 International League Against Epilepsy.

From Freud's dream-work to Bion's work of dreaming: the changing conception of dreaming in psychoanalytic theory.

PubMed

Schneider, John A

2010-06-01

Bion moved psychoanalytic theory from Freud's theory of dream-work to a concept of dreaming in which dreaming is the central aspect of all emotional functioning. In this paper, I first review historical, theoretical, and clinical aspects of dreaming as seen by Freud and Bion. I then propose two interconnected ideas that I believe reflect Bion's split from Freud regarding the understanding of dreaming. Bion believed that all dreams are psychological works in progress and at one point suggested that all dreams contain elements that are akin to visual hallucinations. I explore and elaborate Bion's ideas that all dreams contain aspects of emotional experience that are too disturbing to be dreamt, and that, in analysis, the patient brings a dream with the hope of receiving the analyst's help in completing the unconscious work that was entirely or partially too disturbing for the patient to dream on his own. Freud views dreams as mental phenomena with which to understand how the mind functions, but believes that dreams are solely the 'guardians of sleep,' and not, in themselves, vehicles for unconscious psychological work and growth until they are interpreted by the analyst. Bion extends Freud's ideas, but also departs from Freud and re-conceives of dreaming as synonymous with unconscious emotional thinking - a process that continues both while we are awake and while we are asleep. From another somewhat puzzling perspective, he views dreams solely as manifestations of what the dreamer is unable to think.

Automatic gender detection of dream reports: A promising approach.

A computer program was developed in an attempt to differentiate the dreams of males from females. Hypothesized gender predictors were based on previous literature concerning both dream content and written language features. Dream reports from home-collected dream diaries of 100 male (144 dreams) and 100 female (144 dreams) adolescent Anglophones were matched for equal length. They were first scored with the Hall and Van de Castle (HVDC) scales and quantified using DreamSAT. Two male and two female undergraduate students were asked to read all dreams and predict the dreamer's gender. They averaged a pairwise percent correct gender prediction of 75.8% (κ=0.516), while the Automatic Analysis showed that the computer program's accuracy was 74.5% (κ=0.492), both of which were higher than chance of 50% (κ=0.00). The prediction levels were maintained when dreams containing obvious gender identifiers were eliminated and integration of HVDC scales did not improve prediction. Copyright © 2016 Elsevier Inc.

Similarities and differences in dream content at the cross-cultural, gender, and individual levels.

The similarities and differences in dream content at the cross-cultural, gender, and individual levels provide one starting point for carrying out studies that attempt to discover correspondences between dream content and various types of waking cognition. Hobson and Kahn's (Hobson, J. A., & Kahn, D. (2007). Dream content: Individual and generic aspects. Consciousness and Cognition, 16, 850-858.) conclusion that dream content may be more generic than most researchers realize, and that individual differences are less salient than usually thought, provides the occasion for a review of findings based on the Hall and Van de Castle (Hall, C., & Van de Castle, R. (1966). The content analysis of dreams. New York: Appleton-Century-Crofts.) coding system for the study of dream content. Then new findings based on a computationally intensive randomization strategy are presented to show the minimum sample sizes needed to detect gender and individual differences in dream content. Generally speaking, sample sizes of 100-125 dream reports are needed because most dream elements appear in less than 50% of dream reports and the magnitude of the differences usually is not large.

The analysis of dreams was central in demonstrating Freud's theory of mind and the power of unconscious forces. Many analysts informally comment that dreams no longer seem to hold the same centrality they had for analysts who were trained prior to the 1980s. This paper presents a brief study assessing whether there has been a change in the teaching of dreams in psychoanalytic institutes. Comparison of theoretical and clinical courses on dreams in 1980-1981 and 1998-1999 indicates that the actual number of hours devoted to teaching dreams has in fact decreased. However, there are indications that a renewal of interest in dreams may now be occurring, at least in some institutes. The relationship between views on the role of dreams and perspectives on psychoanalysis itself is discussed.

The content of recurrent dreams in young adolescents

Studies on children’s recurrent dreams have been largely anecdotal and based on adults’ recollections of dreams experienced during childhood. We collected 102 reports of recurrent dreams from a sample of young adolescents aged between 11 and 15 years and scored the narratives using a range of content measures, including in relation to the threat simulation theory (TST) of dreaming. The most frequently reported themes involved confrontations with monsters or animals, followed by physical aggressions, falling and being chased. Recurrent dreams were more likely to include negative content elements than positive elements. Only half of the recurrent dreams contained threatening elements and their analysis provided mixed support for the TST. Differences between the content of recurrent dreams reported by young adolescent versus adults are discussed as are possible sex effects and key issues that remain to be addressed by future research.

A Systematic Change in Dreams after 9/11/01

Hartmann, Ernest; Brezler, Tyler

2008-01-01

Objective: Previous studies of dreams after trauma and stress have found increases in the power of the central image of the dream. However, it has been difficult to perform properly controlled studies of dreams before and after trauma. The present study is designed to compare dreams before and after 9/11/01 in the same persons. The assumption is that the events of 9/11 produced mild trauma or at the very least emotional arousal in everyone living in the United States. Methods: Forty-four persons in the United States who had been recording all their dreams for years each provided 20 consecutive dreams from their records—the last 10 recorded before 9/11 and the first 10 after 9/11. These dreams were assigned random numbers and scored on a blind basis using a number of rating scales with established reliability. Results: Dreams after 9/11 showed a highly significant increase in central image intensity, as well as central image proportion (number of dreams with scorable central images) but no change in dream length, dream-likeness, overall vividness, or content involving airplanes or tall buildings. There were no “exact replay” dreams picturing the actual events of 9/11 seen repeatedly on TV. Conclusions: These results are consistent with the Contemporary Theory of Dreaming, which emphasizes the role of underlying emotion in producing central dream imagery and suggests that the intensity of the central dream imagery is related to the power of the underlying emotion.

2007-10-01

Whereas the effect of sex and age on dream recall have been studied widely, socioeconomic status has rarely been investigated. However, two studies reported that higher socioeconomic status was related to greater frequency of dream recall. In the present sample of 612 Chinese students from three different schools, one elite (high socioeconomic status), one rural (low socioeconomic status) and one intermediate, analysis of variance indicated no significant association between frequency of dream recall and socioeconomic status. Researchers could investigate whether "dream socialization," e.g., encouragement of a child to remember his dreams, depends on socioeconomic background, whether these processes are mediated by culture.

Behavioral and Brain Sciences, 23(6), 877-901]. Our findings suggest the terrorist attacks had a tangible impact on the content of many people's dreams, but did not fundamentally alter the cognitive processing features of their dreaming. The 9/11 attacks affected what they dreamed about, but not the way they dreamed.

Seminars serve as an important, though undervalued, component of psychoanalytic education. The focus of this paper is on the teaching of Freud's The Interpretation of Dreams through a series of seminars presented to analytic candidates at the Toronto Psychoanalytic Institutes. This has been an essential book for introducing generations of candidates to the psychoanalytic concept of the mind and for shaping candidates' understanding and attitudes toward working with their patients' dreams. Four of Freud's basic dream concepts-(1) the method and its application to the exploration of the relationship between manifest and latent dream content, (2) the sources of dreams (day residues), (3) the dream-work, and (4) wish fulfillment-are critically studied in the seminars. Detailed discussion of these basic dream concepts among the candidates and with the teacher, as well as the candidates' feedback at the conclusion of the seminars, are summarized and discussed. Through the teaching and study within the seminar framework of the fundamentals of Freud's dream theory, a shared growth experience results for both teacher and candidates.

Dreams are made of memories, but maybe not for memory.

Llewellyn's claim that rapid eye movement (REM) dream imagery may be related to the processes involved in memory consolidation during sleep is plausible. However, whereas there is voluntary and deliberate intention behind the construction of images in the ancient art of memory (AAOM) method, there is a lack of intentionality in producing dream images. The memory for dreams is also fragile, and dependent on encoding once awake.

Eddy current compensation for delta relaxation enhanced MR by dynamic reference phase modulation.

PubMed

Hoelscher, Uvo Christoph; Jakob, Peter M

2013-04-01

Eddy current compensation by dynamic reference phase modulation (eDREAM) is a compensation method for eddy current fields induced by B 0 field-cycling which occur in delta relaxation enhanced MR (dreMR) imaging. The presented method is based on a dynamic frequency adjustment and prevents eddy current related artifacts. It is easy to implement and can be completely realized in software for any imaging sequence. In this paper, the theory of eDREAM is derived and two applications are demonstrated. The theory describes how to model the behavior of the eddy currents and how to implement the compensation. Phantom and in vivo measurements are carried out and demonstrate the benefits of eDREAM. A comparison of images acquired with and without eDREAM shows a significant improvement in dreMR image quality. Images without eDREAM suffer from severe artifacts and do not allow proper interpretation while images with eDREAM are artifact free. In vivo experiments demonstrate that dreMR imaging without eDREAM is not feasible as artifacts completely change the image contrast. eDREAM is a flexible eddy current compensation for dreMR. It is capable of completely removing the influence of eddy currents such that the dreMR images do not suffer from artifacts.

Biological models contain many parameters whose values are difficult to measure directly via experimentation and therefore require calibration against experimental data. Markov chain Monte Carlo (MCMC) methods are suitable to estimate multivariate posterior model parameter distributions, but these methods may exhibit slow or premature convergence in high-dimensional search spaces. Here, we present PyDREAM, a Python implementation of the (Multiple-Try) Differential Evolution Adaptive Metropolis [DREAM(ZS)] algorithm developed by Vrugt and ter Braak (2008) and Laloy and Vrugt (2012). PyDREAM achieves excellent performance for complex, parameter-rich models and takes full advantage of distributed computing resources, facilitating parameter inference and uncertainty estimation of CPU-intensive biological models.

How to integrate dreaming into a general theory of consciousness--a critical review of existing positions and suggestions for future research.

PubMed

Windt, Jennifer M; Noreika, Valdas

2011-12-01

In this paper, we address the different ways in which dream research can contribute to interdisciplinary consciousness research. As a second global state of consciousness aside from wakefulness, dreaming is an important contrast condition for theories of waking consciousness. However, programmatic suggestions for integrating dreaming into broader theories of consciousness, for instance by regarding dreams as a model system of standard or pathological wake states, have not yielded straightforward results. We review existing proposals for using dreaming as a model system, taking into account concerns about the concept of modeling and the adequacy and practical feasibility of dreaming as a model system. We conclude that existing modeling approaches are premature and rely on controversial background assumptions. Instead, we suggest that contrastive analysis of dreaming and wakefulness presents a more promising strategy for integrating dreaming into a broader research context and solving many of the problems involved in the modeling approach.

Dreams In Jungian Psychology: The use of Dreams as an Instrument For Research, Diagnosis and Treatment of Social Phobia.

Khodarahimi, Siamak

2009-10-01

The significance of dreams has been explained in psychoanalysis, depth psychology and gestalt therapy. There are many guidelines in analytic psychology for dream interpretation and integration in clinical practice. The present study, based on the Jungian analytic model, incorporated dreams as an instrument for assessment of aetiology, the psychotherapy process and the outcome of treatment for social phobia within a clinical case study. This case study describes the use of dream analysis in treating a female youth with social phobia. The present findings supported the three stage paradigm efficiency in the Jungian model for dream working within a clinical setting, i.e. written details, reassembly with amplification and assimilation. It was indicated that childhood and infantile traumatic events, psychosexual development malfunctions, and inefficient coping skills for solving current life events were expressed in the patient's dreams. Dreams can reflect a patient's aetiology, needs, illness prognosis and psychotherapy outcome. Dreams are an instrument for the diagnosis, research and treatment of mental disturbances in a clinical setting.

DREAM (Downstream Regulatory Element Antagonist Modulator) contributes to synaptic depression and contextual fear memory

PubMed Central

2010-01-01

The downstream regulatory element antagonist modulator (DREAM), a multifunctional Ca2+-binding protein, binds specifically to DNA and several nucleoproteins regulating gene expression and with proteins outside the nucleus to regulate membrane excitability or calcium homeostasis. DREAM is highly expressed in the central nervous system including the hippocampus and cortex; however, the roles of DREAM in hippocampal synaptic transmission and plasticity have not been investigated. Taking advantage of transgenic mice overexpressing a Ca2+-insensitive DREAM mutant (TgDREAM), we used integrative methods including electrophysiology, biochemistry, immunostaining, and behavior tests to study the function of DREAM in synaptic transmission, long-term plasticity and fear memory in hippocampal CA1 region. We found that NMDA receptor but not AMPA receptor-mediated current was decreased in TgDREAM mice. Moreover, synaptic plasticity, such as long-term depression (LTD) but not long-term potentiation (LTP), was impaired in TgDREAM mice. Biochemical experiments found that DREAM interacts with PSD-95 and may inhibit NMDA receptor function through this interaction. Contextual fear memory was significantly impaired in TgDREAM mice. By contrast, sensory responses to noxious stimuli were not affected. Our results demonstrate that DREAM plays a novel role in postsynaptic modulation of the NMDA receptor, and contributes to synaptic plasticity and behavioral memory. PMID:20205763

To conduct a comprehensive and comparative study of prospectively collected bad dream and nightmare reports using a broad range of dream content variables. Correlational and descriptive. Participants' homes. Three hundred thirty-one adult volunteers (55 men, 275 women, 1 not specified; mean age = 32.4 ± 14.8 y). N/A. Five hundred seventy-two participants kept a written record of all of their remembered dreams in a log for 2 to 5 consecutive weeks. A total of 9,796 dream reports were collected and the content of 253 nightmares and 431 bad dreams reported by 331 participants was investigated. Physical aggression was the most frequently reported theme in nightmares, whereas interpersonal conflicts predominated in bad dreams. Nightmares were rated by participants as being substantially more emotionally intense than were bad dreams. Thirty-five percent of nightmares and 55% of bad dreams contained primary emotions other than fear. When compared to bad dreams, nightmares were more bizarre and contained substantially more aggressions, failures, and unfortunate endings. The results have important implications on how nightmares are conceptualized and defined and support the view that when compared to bad dreams, nightmares represent a somewhat rarer-and more severe-expression of the same basic phenomenon.

Dale, Allyson; Lafrenière, Alexandre; De Koninck, Joseph

2017-03-01

The present study was a first look at the ontogenetic pattern of dream content across the lifespan for men. The participants included 50 Canadian men in each of 5 age groups, from adolescence to old age including 12-17, 18-24, 25-39, 40-64, and 65-85. The last age group included 31 participants, totaling 231 males. One dream per participant was scored by two independent judges using content analysis. Trend analysis was used to determine the lifespan-developmental pattern of the dream content categories. Results demonstrated a predominance of aggressive dream imagery in the adolescent age group in line with social-developmental research. These patterns of dream imagery reflect the waking developmental patterns as proposed by social theories and recognized features of aging. Limitations and suggestions for future research, including the examining of the developmental pattern of gender differences across the lifespan, are discussed. Copyright © 2017 Elsevier Inc.

DREAM challenges are community competitions designed to advance computational methods and address fundamental questions in system biology and translational medicine. Each challenge asks participants to develop and apply computational methods to either predict unobserved outcomes or to identify unknown model parameters given a set of training data. Computational methods are evaluated using an automated scoring metric, scores are posted to a public leaderboard, and methods are published to facilitate community discussions on how to build improved methods. By engaging participants from a wide range of science and engineering backgrounds, DREAM challenges can comparatively evaluate a wide range of statistical, machine learning, and biophysical methods. Here, we describe DREAMTools, a Python package for evaluating DREAM challenge scoring metrics. DREAMTools provides a command line interface that enables researchers to test new methods on past challenges, as well as a framework for scoring new challenges. As of March 2016, DREAMTools includes more than 80% of completed DREAM challenges. DREAMTools complements the data, metadata, and software tools available at the DREAM website http://dreamchallenges.org and on the Synapse platform at https://www.synapse.org.

Assessment of SWE data assimilation for ensemble streamflow predictions

2014-11-01

An assessment of data assimilation (DA) for Ensemble Streamflow Prediction (ESP) using seasonal water supply hindcasting in the North Fork of the American River Basin (NFARB) and the National Weather Service (NWS) hydrologic forecast models is undertaken. Two parameter sets, one from the California Nevada River Forecast Center (RFC) and one from the Differential Evolution Adaptive Metropolis (DREAM) algorithm, are tested. For each parameter set, hindcasts are generated using initial conditions derived with and without the inclusion of a DA scheme that integrates snow water equivalent (SWE) observations. The DREAM-DA scenario uses an Integrated Uncertainty and Ensemble-based data Assimilation (ICEA) framework that also considers model and parameter uncertainty. Hindcasts are evaluated using deterministic and probabilistic forecast verification metrics. In general, the impact of DA on the skill of the seasonal water supply predictions is mixed. For deterministic (ensemble mean) predictions, the Percent Bias (PBias) is improved with integration of the DA. DREAM-DA and the RFC-DA have the lowest biases and the RFC-DA has the lowest Root Mean Squared Error (RMSE). However, the RFC and DREAM-DA have similar RMSE scores. For the probabilistic predictions, the RFC and DREAM have the highest Continuous Ranked Probability Skill Scores (CRPSS) and the RFC has the best discrimination for low flows. Reliability results are similar between the non-DA and DA tests and the DREAM and DREAM-DA have better reliability than the RFC and RFC-DA for forecast dates February 1 and later. Despite producing improved streamflow simulations in previous studies, the hindcast analysis suggests that the DA method tested may not result in obvious improvements in streamflow forecasts. We advocate that integration of hindcasting and probabilistic metrics provides more rigorous insight on model performance for forecasting applications, such as in this study.

Although napping has received attention because of its associations with health and use as a method to understand the function of sleep, to our knowledge no study has systematically and statistically assessed reasons for napping. Using factor analysis, we determined the underlying structure of reasons for napping in diverse undergraduates (N = 430, 59% female) and examined their relationships with self-reported sleep, psychological health, and physical health. The five reasons for napping can be summarized using the acronym DREAM (Dysregulative, Restorative, Emotional, Appetitive, and Mindful). Only Emotional reasons for napping were uniformly related to lower well-being. The use of factor analysis raises possibilities for future research, including examining the stability, structure, and psychological and physical health processes related to napping throughout the lifespan.

Work with dreams in the group analysis represents an important part of the analytical work, with insight into unconscious experiences of the individual dreamer, and his transferrential relations with the therapist, other members of the group, and with the group as a whole. The way dreams are addressed varies from one therapist to another, and in line with that, members of the group have varying frequency of dreams. In groups of psychotic patients dreams are generally rarely discussed and interpreted by the group, with analysis mainly resting on the manifested content. This paper describes a long-term group of psychotic patients which, after sharing the dreams of several members and daydreams of one female patient, their interpretation and reception in the group achieved better cohesion and improved communication and interaction, i.e. created a group matrix. Furthermore, through the content of dreams in the group, traumatic war experiences of several of the group members were opened and discussed, which brought with it recollections of the traumatic life situations of other group members. In expressing a daydream, a female member of the group revealed the background for her behaviour which was earlier interpreted as a negative symptom of the illness.

This paper provides a psychoanalytic interpretation of an element in the Irma dream that Freud had ignored in his own interpretation. The allusion to Leopold von Auenbrugger, the originator of percussion as a method of clinical investigation, which appears in the manifest dream reflects Freud's hopes and fears about how his Interpretation of Dreams and the new human science established there would be received by his medical colleagues.

In this article I defend Freud's method of dream interpretation against those who criticize it as involving a fallacy-namely, the reverse causal fallacy-and those who criticize it as permitting many interpretations, indeed any that the interpreter wants to put on the dream. The first criticism misconstrues the logic of the interpretative process: it does not involve an unjustified reversal of causal relations, but rather a legitimate attempt at an inference to the best explanation. The judgement of whether or not a particular interpretation is the best explanation depends on the details of the case in question. I outline the kinds of probabilities involved in making the judgement. My account also helps to cash out the metaphors of the jigsaw and crossword puzzles that Freudians have used in response to the 'many interpretations' objection. However, in defending Freud's method of dream interpretation, I do not thereby defend his theory of dreams, which cannot be justified by his interpretations alone.

[Are oppressive dreams indicators in bereavement?].

It is widely believed that oppressive dreams are frequent in bereavement--despite the lack of scientific investigations of the subject. The aims of our study were the analysis of dream quality as well as the correlates of oppressive dreams in bereavement. Participants with (N = 473) and without bereavement were compared upon the database of a national representative study (Hungarostudy Epidemiological Panel Survey 2006, N = 4329). Dream contents were assessed with the Dream Quality Questionnaire (DQQ). Depressive symptoms (BDI-S) and the presence anxiety were also investigated. Oppressive dreams occurred significantly higher frequency in the first year of bereavement (men: F = 17.525, p < 0.001, women: F = 8.291, p = 0.004). Oppressive dreams were significantly associated with anxiety (F = 37.089, p < 0.001) and with depressive symptoms (F = 50.562, p < 0.001). Oppressive dreams are significantly more frequent in the first year of bereavement, and may act as indicators of bereavement-linked mental health consequences like depression and anxiety. These are often masked by the symptoms of grief and therefore remain untreated. Our preliminary results could be a starting point for the development of further research aiming to clarify the relationship amongst dream contents, anxiety, and depression in bereavement.

Dreams, reality and memory: confabulations in lucid dreamers implicate reality-monitoring dysfunction in dream consciousness.

Dreams might represent a window on altered states of consciousness with relevance to psychotic experiences, where reality monitoring is impaired. We examined reality monitoring in healthy, non-psychotic individuals with varying degrees of dream awareness using a task designed to assess confabulatory memory errors - a confusion regarding reality whereby information from the past feels falsely familiar and does not constrain current perception appropriately. Confabulatory errors are common following damage to the ventromedial prefrontal cortex (vmPFC). Ventromedial function has previously been implicated in dreaming and dream awareness. In a hospital research setting, physically and mentally healthy individuals with high (n = 18) and low (n = 13) self-reported dream awareness completed a computerised cognitive task that involved reality monitoring based on familiarity across a series of task runs. Signal detection theory analysis revealed a more liberal acceptance bias in those with high dream awareness, consistent with the notion of overlap in the perception of dreams, imagination and reality. We discuss the implications of these results for models of reality monitoring and psychosis with a particular focus on the role of vmPFC in default-mode brain function, model-based reinforcement learning and the phenomenology of dreaming and waking consciousness.

The dream is a unique psychodynamically informative instrument for evaluating the subjective correlates of brain activity during REM sleep. These include feelings, percepts, memories, wishes, fantasies, impulses, conflicts, and defenses, as well as images of self and others. Dream analysis can be used in a variety of clinical settings to assist in diagnostic assessment, psychodynamic formulation, evaluation of clinical change, and the management of medically ill patients. Dreams may serve as the initial indicators of transference, resistance, impending crisis, acting-out, conflict resolution, and decision-making. A clinically functional categorization of dreams can facilitate an understanding of psychopathology, psychodynamics, personality structure, and various components of the psychotherapeutic process. Examples of different types of dreams are provided to illustrate their relevance and use in various clinical situations. PMID:11696648

Dreams are a most remarkable experiment in psychology and neuroscience, conducted every night in every sleeping person. They show that our brain, disconnected from the environment, can generate by itself an entire world of conscious experiences. Content analysis and developmental studies have furthered our understanding of dream phenomenology. In parallel, brain lesion studies, functional imaging, and neurophysiology have advanced our knowledge of the neural basis of dreaming. It is now possible to start integrating these two strands of research in order to address some fundamental questions that dreams pose for cognitive neuroscience: how conscious experiences in sleep relate to underlying brain activity; why the dreamer is largely disconnected from the environment; and whether dreaming is more closely related to mental imagery or to perception.

Dreaming and insight

This paper addresses claims that dreams can be a source of personal insight. Whereas there has been anecdotal backing for such claims, there is now tangential support from findings of the facilitative effect of sleep on cognitive insight, and of REM sleep in particular on emotional memory consolidation. Furthermore, the presence in dreams of metaphorical representations of waking life indicates the possibility of novel insight as an emergent feature of such metaphorical mappings. In order to assess whether personal insight can occur as a result of the consideration of dream content, 11 dream group discussion sessions were conducted which followed the Ullman Dream Appreciation technique, one session for each of 11 participants (10 females, 1 male; mean age = 19.2 years). Self-ratings of deepened self-perception and personal gains from participation in the group sessions showed that the Ullman technique is an effective procedure for establishing connections between dream content and recent waking life experiences, although wake life sources were found for only 14% of dream report text. The mean Exploration-Insight score on the Gains from Dream Interpretation questionnaire was very high and comparable to outcomes from the well-established Hill (1996) therapist-led dream interpretation method. This score was associated between-subjects with pre-group positive Attitude Toward Dreams (ATD). The need to distinguish “aha” experiences as a result of discovering a waking life source for part of a dream, from “aha” experiences of personal insight as a result of considering dream content, is discussed. Difficulties are described in designing a control condition to which the dream report condition can be compared. PMID:24550849

Background Anesthetic dreaming and anesthesia awareness are well distinct phenomena. Although the incidence of intraoperative awareness is more common among patients who reported a dream after surgery, the exact correlation between the two phenomena remains an unsolved rebus. The main purpose of this study was to investigate anesthetic dreaming, anesthesia awareness and psychological consequences eventually occurred under deep sedation. Intraoperative dreaming experiences were correlated with dream features in natural sleep. Methods Fifty-one patients, undergoing surgical excision of fibroadenomas under a Bispectral index-guided deep sedation anesthesia with propofol target controlled infusion, were enrolled into this prospective study. Psychological assessment was performed through the State Trait Anxiety Inventory. A questionnaire was adopted to register dreaming and anesthesia awareness. Data were collected after emergence (t0), 24 hours (t1), 1 month (t2), 6 months (t3). Results Six patients (12%) reported anesthetic dreaming at t0 confirming the response at each subsequent evaluation. One patient (2%) confirmed dreaming during anesthesia in all, but denied it at t0. There was a high correlation between the intraoperative dream contents and the features of dreams in natural sleep. No cases of anesthesia awareness were detected. A similar level of satisfaction was observed in dreaming and no-dreaming patients. Conclusions Anesthetic dreaming does not seem to influence satisfaction of patients undergoing deep sedation with propofol target controlled infusion. A psychological assessment would seem to improve the evaluation of possible psychological consequences in dreamer patient. PMID:29108303

Study objectives: The ultradian NREM-REM sleep cycle and the circadian modulation of REM sleep sum to generate dreaming. Here we investigated age-related changes in dream recall, number of dreams, and emotional domain characteristics of dreaming during both NREM and REM sleep. Design: Analysis of dream recall and sleep EEG (NREM/REM sleep) during a 40-h multiple nap protocol (150 min of wakefulness and 75 min of sleep) under constant routine conditions. Setting: Centre for Chronobiology, Psychiatric Hospital of the University of Basel, Basel, Switzerland. Participants: Seventeen young (20-31 years) and 15 older (57-74 years) healthy volunteers Interventions: N/A. Measurements and Results: Dream recall and number of dreams varied significantly across the circadian cycle and between age groups, with older subjects exhibiting fewer dreams (P < 0.05), particularly after naps scheduled during the biological day, closely associated with the circadian rhythm of REM sleep. No significant age differences were observed for the emotional domain of dream content. Conclusions: Since aging was associated with attenuated amplitude in the circadian modulation of REM sleep, our data suggest that the age-related decrease in dream recall can result from an attenuated circadian modulation of REM sleep.

This study investigates evidence, from dream reports, for memory consolidation during sleep. It is well-known that events and memories from waking life can be incorporated into dreams. These incorporations can be a literal replication of what occurred in waking life, or, more often, they can be partial or indirect. Two types of temporal relationship have been found to characterize the time of occurrence of a daytime event and the reappearance or incorporation of its features in a dream. These temporal relationships are referred to as the day-residue or immediate incorporation effect, where there is the reappearance of features from events occurring on the immediately preceding day, and the dream-lag effect, where there is the reappearance of features from events occurring 5-7 days prior to the dream. Previous work on the dream-lag effect has used spontaneous home recalled dream reports, which can be from Rapid Eye Movement Sleep (REM) and from non-Rapid Eye Movement Sleep (NREM). This study addresses whether the dream-lag effect occurs only for REM sleep dreams, or for both REM and NREM stage 2 (N2) dreams. 20 participants kept a daily diary for over a week before sleeping in the sleep laboratory for 2 nights. REM and N2 dreams collected in the laboratory were transcribed and each participant rated the level of correspondence between every dream report and every diary record. The dream-lag effect was found for REM but not N2 dreams. Further analysis indicated that this result was not due to N2 dream reports being shorter, in terms of number of words, than the REM dream reports. These results provide evidence for a 7-day sleep-dependent non-linear memory consolidation process that is specific to REM sleep, and accord with proposals for the importance of REM sleep to emotional memory consolidation.

Bayesian calibration of terrestrial ecosystem models: a study of advanced Markov chain Monte Carlo methods

Calibration of terrestrial ecosystem models is important but challenging. Bayesian inference implemented by Markov chain Monte Carlo (MCMC) sampling provides a comprehensive framework to estimate model parameters and associated uncertainties using their posterior distributions. The effectiveness and efficiency of the method strongly depend on the MCMC algorithm used. In this work, a differential evolution adaptive Metropolis (DREAM) algorithm is used to estimate posterior distributions of 21 parameters for the data assimilation linked ecosystem carbon (DALEC) model using 14 years of daily net ecosystem exchange data collected at the Harvard Forest Environmental Measurement Site eddy-flux tower. The calibration of DREAM results in a better model fit and predictive performance compared to the popular adaptive Metropolis (AM) scheme. Moreover, DREAM indicates that two parameters controlling autumn phenology have multiple modes in their posterior distributions while AM only identifies one mode. The application suggests that DREAM is very suitable to calibrate complex terrestrial ecosystem models, where the uncertain parameter size is usually large and existence of local optima is always a concern. In addition, this effort justifies the assumptions of the error model used in Bayesian calibration according to the residual analysis. The result indicates that a heteroscedastic, correlated, Gaussian error model is appropriate for the problem, and the consequent constructed likelihood function can alleviate the underestimation of parameter uncertainty that is usually caused by using uncorrelated error models.

Exploring the dream world from a modern, or post-modern, perspective, especially through the lens of contemporary technologies, often leads us as researchers to see ourselves as engaged in a new and revolutionary discourse. In fact, this self-image is a profoundly ahistorical one, because it ignores the contributions of ancient, medieval and Renaissance oneirologists who wrote extensively, albeit in different terms and images of lucidity, prerecognition, day residue, wish fulfillment, incubation, problem solving, REM, obe, and the collective unconscious. There are also analogues in these early accounts to anxiety, recurrent, mirror, telepathic, shared, flying, and death dreams. Dream interpretation through music, analysis of dream as narrative, sophisticated theories about memory and language and symbolization are all part of the tradition. Further, early texts pose many issues in sleep and dream research which are not currently being pursued. We dream workers of the late twentieth century should therefore fortify ourselves with knowledge of the oneiric past as one important way to enhance our dream work in the twenty-first century.

dREAM complexes represent the predominant form of E2F/RBF repressor complexes in Drosophila. dREAM associates with thousands of sites in the fly genome but its mechanism of action is unknown. To understand the genomic context in which dREAM acts we examined the distribution and localization of Drosophila E2F and dREAM proteins. Here we report a striking and unexpected overlap between dE2F2/dREAM sites and binding sites for the insulator-binding proteins CP190 and Beaf-32. Genetic assays show that these components functionally co-operate and chromatin immunoprecipitation experiments on mutant animals demonstrate that dE2F2 is important for association of CP190 with chromatin. dE2F2/dREAM binding sites are enriched at divergently transcribed genes, and the majority of genes upregulated by dE2F2 depletion represent the repressed half of a differentially expressed, divergently transcribed pair of genes. Analysis of mutant animals confirms that dREAM and CP190 are similarly required for transcriptional integrity at these gene pairs and suggest that dREAM functions in concert with CP190 to establish boundaries between repressed/activated genes. Consistent with the idea that dREAM co-operates with insulator-binding proteins, genomic regions bound by dREAM possess enhancer-blocking activity that depends on multiple dREAM components. These findings suggest that dREAM functions in the organization of transcriptional domains. PMID:25053843

DREAM: An Efficient Methodology for DSMC Simulation of Unsteady Processes

NASA Astrophysics Data System (ADS)

Cave, H. M.; Jermy, M. C.; Tseng, K. C.; Wu, J. S.

2008-12-01

A technique called the DSMC Rapid Ensemble Averaging Method (DREAM) for reducing the statistical scatter in the output from unsteady DSMC simulations is introduced. During post-processing by DREAM, the DSMC algorithm is re-run multiple times over a short period before the temporal point of interest thus building up a combination of time- and ensemble-averaged sampling data. The particle data is regenerated several mean collision times before the output time using the particle data generated during the original DSMC run. This methodology conserves the original phase space data from the DSMC run and so is suitable for reducing the statistical scatter in highly non-equilibrium flows. In this paper, the DREAM-II method is investigated and verified in detail. Propagating shock waves at high Mach numbers (Mach 8 and 12) are simulated using a parallel DSMC code (PDSC) and then post-processed using DREAM. The ability of DREAM to obtain the correct particle velocity distribution in the shock structure is demonstrated and the reduction of statistical scatter in the output macroscopic properties is measured. DREAM is also used to reduce the statistical scatter in the results from the interaction of a Mach 4 shock with a square cavity and for the interaction of a Mach 12 shock on a wedge in a channel.

Five proficient lucid dreamers (26-34 yr. old, M=29.8, SD=3.0; one woman and four men) participated. Analysis showed that the time needed for counting in a lucid dream is comparable to the time needed for counting in wakefulness, but motor activities required more time in lucid dreams than in the waking state.

Hospice patients often struggle with loss of meaning, while many experience meaningful dreams. The purpose of this study was to conduct a preliminary exploration into the process and therapeutic outcomes of meaning-centered dream work with hospice patients. A meaning-centered variation of the cognitive-experiential model of dream work (Hill, 1996; 2004) was tested with participants. This variation was influenced by the tenets of meaning-centered psychotherapy (Breitbart et al., 2012). A total of 12 dream-work sessions were conducted with 7 hospice patients (5 women), and session transcripts were analyzed using the consensual qualitative research (CQR) method (Hill, 2012). Participants also completed measures of gains from dream interpretation in terms of existential well-being and quality of life. Participants' dreams generally featured familiar settings and living family and friends. Reported images from dreams were usually connected to feelings, relationships, and the concerns of waking life. Participants typically interpreted their dreams as meaning that they needed to change their way of thinking, address legacy concerns, or complete unfinished business. Generally, participants developed and implemented action plans based on these interpretations, despite their physical limitations. Participants described dream-work sessions as meaningful, comforting, and helpful. High scores on a measure of gains from dream interpretation were reported, consistent with qualitative findings. No adverse effects were reported or indicated by assessments. Our results provided initial support for the feasibility and helpfulness of dream work in this population. Implications for counseling with the dying and directions for future research were also explored.

Disappearance of "phantom limb" and amputated arm usage during dreaming in REM sleep behaviour disorder.

PubMed

Vetrugno, Roberto; Arnulf, Isabelle; Montagna, Pasquale

2009-01-01

Limb amputation is followed, in approximately 90% of patients, by "phantom limb" sensations during wakefulness. When amputated patients dream, however, the phantom limb may be present all the time, part of the time, intermittently or not at all. Such dreaming experiences in amputees have usually been obtained only retrospectively in the morning and, moreover, dreaming is normally associated with muscular atonia so the motor counterpart of the phantom limb experience cannot be observed directly. REM sleep behaviour disorder (RBD), in which muscle atonia is absent during REM sleep and patients act out their dreams, allows a more direct analysis of the "phantom limb" phenomena and their modifications during sleep.

Scientific study of dreams requires the most objective methods to reliably analyze dream content. In this context, artificial intelligence should prove useful for an automatic and non subjective scoring technique. Past research has utilized word search and emotional affiliation methods, to model and automatically match human judges' scoring of dream report's negative emotional tone. The current study added word associations to improve the model's accuracy. Word associations were established using words' frequency of co-occurrence with their defining words as found in a dictionary and an encyclopedia. It was hypothesized that this addition would facilitate the machine learning model and improve its predictability beyond those of previous models. With a sample of 458 dreams, this model demonstrated an improvement in accuracy from 59% to 63% (kappa=.485) on the negative emotional tone scale, and for the first time reached an accuracy of 77% (kappa=.520) on the positive scale.

This study investigated the relation between generalized anxiety disorder (GAD) and frequency of bad dreams in older adults. A secondary analysis from a randomized clinical trial comparing cognitive behavioral therapy for anxiety (CBT) to enhanced usual care (EUC), it assessed bad dream frequency at baseline, post-treatment (3 months), and 6, 9, 12 and 15 months. Of 227 participants (mean age = 67.4), 134 met GAD diagnostic criteria (CBT = 70, EUC = 64), with the remaining 93 serving as a comparison group. Patients with GAD had significantly more bad dreams than those without, and bad dream frequency was significantly associated with depression, anxiety, worry, and poor quality of life. CBT for anxiety significantly reduced bad dream frequency at post-treatment and throughout follow-up compared to EUC. PMID:23470116

Introduction The aim of this study was to examine the level of lucidity and its relation with metacognitive beliefs and dream anxiety in medical students. Methods Nine hundred sixteen medical students were enrolled in the study. The participants were assessed with the Lucidity and Consciousness in Dreams Scale (LuCiD), the Metacognition Questionnaire-30 (MCQ-30), and the Van Dream Anxiety Scale (VDAS). Results There was no significant difference in mean total lucidity score between females and males, but there were some significant sex differences in subscales of lucidity, and control was significantly higher in male students, while realism, thought, and dissociation were significantly higher in female students. In addition, females had more dream anxiety levels, higher total MCQ-30 scores, and higher cognitive confidence and uncontrollability scores according to Metacognition Questionnaire-30 than males. We also found that the mean lucidity level was positively correlated with the mean total metacognition score and the mean total dream anxiety level. Discussion Our results suggest that female medical students tend to have more realistic dreams (p=0.018), have more logical thoughts during dreaming (p=0.011), and have a more dissociative experience during dreaming (p=0.028), while male medical students have more controlled dream events (p=0.002). There seem to be differences according to lucidity features between sexes, and the relationship between subdomains of lucidity and metacognition might lead to new therapeutic approaches to several psychiatric disorders such as anxiety disorders.

The aim of this research study was to investigate the role of children's dreams in the practice of child psychoanalysis today, and to explore contemporary psychoanalytic understanding of children's dreams. This pilot study consisted of two stages. The first involved a document analysis of published articles in The Psychoanalytic Study of the Child, making a comparison between those of the early 1950s and the 1990s, in order to see in what way the discourse around children's dreams within the psychoanalytic literature has changed over time. The second stage, based on questionnaires and in-depth interviews, attempted to understand in more detail the way contemporary child analysts, working in the Anna Freudian tradition, think about dreams and use them in their clinical practice. Results suggest that there has been a decreased focus on dreams in a clinical context over time, and that this may partly be a consequence of changing theoretical models and changes in training. When work with dreams does take place, it appears that child analysts have

Many previous observers have reported some qualitative similarities between the normal mental state of dreaming and the abnormal mental state of psychosis. Recent psychological, tomographic, electrophysiological, and neurochemical data appear to confirm the functional similarities between these 2 states. In this study, the hypothesis of the dreaming brain as a neurobiological model for psychosis was tested by focusing on cognitive bizarreness, a distinctive property of the dreaming mental state defined by discontinuities and incongruities in the dream plot, thoughts, and feelings. Cognitive bizarreness was measured in written reports of dreams and in verbal reports of waking fantasies in 30 schizophrenics and 30 normal controls. Seven pictures of the Thematic Apperception Test (TAT) were administered as a stimulus to elicit waking fantasies, and all participating subjects were asked to record their dreams upon awakening. A total of 420 waking fantasies plus 244 dream reports were collected to quantify the bizarreness features in the dream and waking state of both subject groups. Two-way analysis of covariance for repeated measures showed that cognitive bizarreness was significantly lower in the TAT stories of normal subjects than in those of schizophrenics and in the dream reports of both groups. The differences between the 2 groups indicated that, under experimental conditions, the waking cognition of schizophrenic subjects shares a common degree of formal cognitive bizarreness with the dream reports of both normal controls and schizophrenics. Though very preliminary, these results support the hypothesis that the dreaming brain could be a useful experimental model for psychosis. PMID:17942480

Few studies have addressed dreaming in patients with sleep apnea. We hypothesized that respiratory events and subsequent oxygen desaturation act as an important physiological trigger and may thus influence dream content in patients with a sleep-related breathing disorder. Seventy-six patients (28 women, mean age 54 years, range 20-82) who underwent polysomnography because of suspected sleep apnea participated in this study. Dream reports and dream questionnaires were collected immediately after first morning awakening, at 5:30 AM, at the sleep laboratory. Dream content analysis with respect to possible respiratory-related content was performed. Patients were stratified into primary snoring, mild, moderate, and severe sleep apnea groups. In 63 patients sleep apnea was diagnosed (mild n = 31, 49.2%, moderate n = 13, 20.6%, severe n = 19, 30.2%), and 13 subjects in whom a sleep-related breathing disorder was not confirmed were included as a control group with primary snoring. There was no significant difference in respiratory-related dream topics between patients and controls. Also, no influence of respiratory parameters measured during polysomnography on dream content was detectable. We failed to detect a difference in dream content between patients with sleep apnea and controls. Further studies are required to determine whether these results indicate that the incorporation of respiratory events into dreams is absent in patients with sleep apnea or represents a bias due to the collection of dream content in the early morning hours. © 2018 American Academy of Sleep Medicine

Microstructural analyses by MRI brain scans and by DTI analysis of MR images were used to investigate the possible relationship between deep gray matter structures (amygdala and hippocampus) and dreaming in healthy subjects. Thirty-four subjects ranging in age 20s to 70s underwent to a MRI protocol for the assessment of volume and mean diffusivity (MD) in the amygdala and hippocampus and were asked to fill out a dream diary via audiotape recording upon morning awakening for two weeks. Multiple regression analyses evaluated the relationships between anatomical measures and quantitative and qualitative measures of the reported dreams. The main result points to a dissociation between some quantitative and qualitative aspects of dream reports. While the mean number of dreams recalled per day did not show any significant relationship with the neuroanatomical measures, significant associations with some qualitative features of the recalled dreams (emotional load, bizarreness, and vividness) and, to some extent, with the length of dream reports were observed. Particularly, a higher MD of the left amygdala, reflecting a decreased microstructural integrity, was associated with shorter dream reports and lower scores on emotional load. Bizarreness of dream reports was negatively correlated with the left amygdala volume and positively correlated with the right amygdala MD. Some specific, although weaker, relationships were also found between bizarreness and hippocampal measures. These findings indicate some direct relationships between volumetric and ultrastructural measures of the hippocampus-amygdala complex and specific qualitative features of dreaming.

In this work, a differential evolution adaptive Metropolis (DREAM) algorithm is used to estimate posterior distributions of 21 parameters for the data assimilation linked ecosystem carbon (DALEC) model using 14 years of daily net ecosystem exchange data collected at the Harvard Forest Environmental Measurement Site eddy-flux tower. The calibration of DREAM results inmore » a better model fit and predictive performance compared to the popular adaptive Metropolis (AM) scheme. Moreover, DREAM indicates that two parameters controlling autumn phenology have multiple modes in their posterior distributions while AM only identifies one mode.

In addition, this effort justifies the assumptions of the error model used in Bayesian calibration according to the residual analysis. Here, the result indicates that a heteroscedastic, correlated, Gaussian error model is appropriate for the problem, and the consequent constructed likelihood function can alleviate the underestimation of parameter uncertainty that is usually caused by using uncorrelated error models.« less

Changes in nuclear Ca2+ homeostasis activate specific gene expression programs and are central to the acquisition and storage of information in the brain. DREAM (downstream regulatory element antagonist modulator), also known as calsenilin/KChIP-3 (K+ channel interacting protein 3), is a Ca2+-binding protein that binds DNA and represses transcription in a Ca2+-dependent manner. To study the function of DREAM in the brain, we used transgenic mice expressing a Ca2+-insensitive/CREB-independent dominant active mutant DREAM (daDREAM). Using genome-wide analysis, we show that DREAM regulates the expression of specific activity-dependent transcription factors in the hippocampus, including Npas4, Nr4a1, Mef2c, JunB, and c-Fos. Furthermore, DREAM regulates its own expression, establishing an autoinhibitory feedback loop to terminate activity-dependent transcription. Ablation of DREAM does not modify activity-dependent transcription because of gene compensation by the other KChIP family members. The expression of daDREAM in the forebrain resulted in a complex phenotype characterized by loss of recurrent inhibition and enhanced long-term potentiation (LTP) in the dentate gyrus and impaired learning and memory. Our results indicate that DREAM is a major master switch transcription factor that regulates the on/off status of specific activity-dependent gene expression programs that control synaptic plasticity, learning, and memory.

Dust is known to aggravate respiratory diseases. This is an issue in the desert southwestern United States, where windblown dust events are common. The Public Health Applications in Remote Sensing (PHAiRS) project aims to address this problem by using remote-sensing products to assist in public health decision support. As part of PHAiRS, a model for simulating desert dust cycles, the Dust Regional Atmospheric Modeling (DREAM) system is employed to forecast dust events in the southwestern US. Thus far, DREAM has been validated in the southwestern US only in the lower part of the atmosphere by comparison with measurement and analysis products from surface synoptic, surface Meteorological Aerodrome Report (METAR), and upper-air radiosonde. This study examines the validity of the DREAM algorithm dust load prediction in the desert southwestern United States by comparison with satellite-based MODIS level 2 and MODIS Deep Blue aerosol products, and ground-based observations from the AERONET network of sunphotometers. Results indicate that there are difficulties obtaining MODIS L2 aerosol optical thickness (AOT) data in the desert southwest due to low AOT algorithm performance over areas with high surface reflectances. MODIS Deep Blue aerosol products show improvement, but the temporal and vertical resolution of MODIS data limit its utility for DREAM evaluation. AERONET AOT data show low correlation to DREAM dust load predictions. The potential contribution of space- or ground-based lidar to the PHAiRS project is also examined.

Brain and sleep maturation covary across different stages of life. At the same time, dream generation and dream recall are intrinsically dependent on the development of neural systems. The aim of this paper is to review the existing studies about dreaming in infancy, adulthood, and the elderly stage of life, assessing whether dream mentation may reflect changes of the underlying cerebral activity and cognitive processes. It should be mentioned that some evidence from childhood investigations, albeit still weak and contrasting, revealed a certain correlation between cognitive skills and specific features of dream reports. In this respect, infantile amnesia, confabulatory reports, dream-reality discerning, and limitation in language production and emotional comprehension should be considered as important confounding factors. Differently, growing evidence in adults suggests that the neurophysiological mechanisms underlying the encoding and retrieval of episodic memories may remain the same across different states of consciousness. More directly, some studies on adults point to shared neural mechanisms between waking cognition and corresponding dream features. A general decline in the dream recall frequency is commonly reported in the elderly, and it is explained in terms of a diminished interest in dreaming and in its emotional salience. Although empirical evidence is not yet available, an alternative hypothesis associates this reduction to an age-related cognitive decline. The state of the art of the existing knowledge is partially due to the variety of methods used to investigate dream experience. Very few studies in elderly and no investigations in childhood have been performed to understand whether dream recall is related to specific electrophysiological pattern at different ages. Most of all, the lack of longitudinal psychophysiological studies seems to be the main issue. As a main message, we suggest that future longitudinal studies should collect dream reports upon awakening from different sleep states and include neurobiological measures with cognitive performances.

Carl Jung's interpretation of Wolfgang Pauli's dreams: The Bailey Island, Maine, and New York City seminars of 1936 and 1937

NASA Astrophysics Data System (ADS)

Brown, Richard Paul

This dissertation reviewed the development of Jung's dream theory and addresses the question as to whether or not Jung was influenced by the dreams of the Nobel Prize winning physicist, Wolfgang Pauli. Jung provided an extensive analysis of Pauli's dreams, which are contained in the lightly edited, unpublished transcripts of lectures delivered in 1936 and 1937. An archival and hermeneutic analysis of the texts reveals a staged process of individuation that Jung related to in many ways because of the parallels to his own personal journey toward individuation. A chronological history of the development of Jung's dream theory is presented, followed by a picture of the relationship between Jung and Pauli. Thereafter, a detailed summary of the seminar transcripts, one given on Bailey Island, Maine, and the other in New York City the following year, is offered with hermeneutic commentary. An analysis of the seminars found that Pauli's dreams did, in part, support Jung's theory. Specifically, while Jung was unable to meet the scientific demands for clear empirical evidence of his dream theory, he did offer his professional and non-professional audiences with a slightly less rigorous example of his dream theory in action, demonstrating that the process shared similarities across peoples, time, and cultures. Additionally, in Pauli he found a superior mind that had gone through the process of individuation in accordance with his theory and his own experience. During the course of research, reference to a document was found in the correspondence in the Jungian Archives in Zurich. This document entitled, "FAREWELL SPEECH, Given by Dr. C. G. Jung on the Occasion of a Dinner Given in His Honor by the Analytical Psychology Club of New York City October 26, 1937" and other related documents were subsequently uncovered in the sub-basement of the Kristine Mann Library in New York City. A synopsis of the discovery and description of the papers contained in the file are discussed in the Conclusion.

End-of-life dreams and visions (ELDVs) have been well documented throughout history and across cultures. The impact of pre-death experiences on dying individuals and their loved ones can be profoundly meaningful. Our aim was to quantify the frequency of dreams/visions experienced by patients nearing the end of life, examine the content and subjective significance of the dreams/visions, and explore the relationship of these factors to time/proximity to death. This mixed-methods study surveyed patients in a hospice inpatient unit using a semi-structured interview. Sixty-six patients admitted to a hospice inpatient unit between January 2011 and July 2012 provided informed consent and participated in the study. The semi-structured interviews contained closed and open-ended questions regarding the content, frequency, and comfort/distress of dreams/visions. Fifty-nine participants comprised the final sample. Most participants reported experiencing at least one dream/vision. Almost half of the dreams/visions occurred while asleep, and nearly all patients indicated that they felt real. The most common dreams/visions included deceased friends/relatives and living friends/relatives. Dreams/visions featuring the deceased (friends, relatives, and animals/pets) were significantly more comforting than those of the living, living and deceased combined, and other people and experiences. As participants approached death, comforting dreams/visions of the deceased became more prevalent. ELDVs are commonly experienced phenomena during the dying process, characterized by a consistent sense of realism and marked emotional significance. These dreams/visions may be a profound source of potential meaning and comfort for the dying, and therefore warrant clinical attention and further research.

Background Systems biology has embraced computational modeling in response to the quantitative nature and increasing scale of contemporary data sets. The onslaught of data is accelerating as molecular profiling technology evolves. The Dialogue for Reverse Engineering Assessments and Methods (DREAM) is a community effort to catalyze discussion about the design, application, and assessment of systems biology models through annual reverse-engineering challenges. Methodology and Principal Findings We describe our assessments of the four challenges associated with the third DREAM conference which came to be known as the DREAM3 challenges: signaling cascade identification, signaling response prediction, gene expression prediction, and the DREAM3 in silico network challenge. The challenges, based on anonymized data sets, tested participants in network inference and prediction of measurements. Forty teams submitted 413 predicted networks and measurement test sets. Overall, a handful of best-performer teams were identified, while a majority of teams made predictions that were equivalent to random. Counterintuitively, combining the predictions of multiple teams (including the weaker teams) can in some cases improve predictive power beyond that of any single method. Conclusions DREAM provides valuable feedback to practitioners of systems biology modeling. Lessons learned from the predictions of the community provide much-needed context for interpreting claims of efficacy of algorithms described in the scientific literature. PMID:20186320

Implementation of unsteady sampling procedures for the parallel direct simulation Monte Carlo method

An unsteady sampling routine for a general parallel direct simulation Monte Carlo method called PDSC is introduced, allowing the simulation of time-dependent flow problems in the near continuum range. A post-processing procedure called DSMC rapid ensemble averaging method (DREAM) is developed to improve the statistical scatter in the results while minimising both memory and simulation time. This method builds an ensemble average of repeated runs over small number of sampling intervals prior to the sampling point of interest by restarting the flow using either a Maxwellian distribution based on macroscopic properties for near equilibrium flows (DREAM-I) or output instantaneous particle data obtained by the original unsteady sampling of PDSC for strongly non-equilibrium flows (DREAM-II). The method is validated by simulating shock tube flow and the development of simple Couette flow. Unsteady PDSC is found to accurately predict the flow field in both cases with significantly reduced run-times over single processor code and DREAM greatly reduces the statistical scatter in the results while maintaining accurate particle velocity distributions. Simulations are then conducted of two applications involving the interaction of shocks over wedges. The results of these simulations are compared to experimental data and simulations from the literature where there these are available. In general, it was found that 10 ensembled runs of DREAM processing could reduce the statistical uncertainty in the raw PDSC data by 2.5-3.3 times, based on the limited number of cases in the present study.

Dreams of personality disordered subjects.

Dreams provide access to underlying personality structure, defensive and adaptive functions, and they elucidate the psychological forces that lead to overt symptomatic behavior. Two hundred three dreams of 39 personality disordered patients were factor analyzed and compared with Hall and Van de Castle's normative data (Hall C, Van de Castle RI [1966] The content analysis of dreams. New York: Appleton-Century-Crofts). Results included a five-factor solution that sheds light on some core issues of the dreamers. Comparisons between the groups resulted in the personality-disordered group demonstrating more estrangement in their dreams, fewer interactions, and more emotionality. In their interactions, they demonstrated a lower ratio of aggressive interactions yet a higher tendency to view themselves as the aggressor. Results are related to theoretical literature on personality and defensive styles, mostly from a psychodynamic perspective.

To clarify whether motor behaviors and/ or vocalizations during REM sleep, which do not yet fulfill diagnostic criteria for REM sleep behavior disorder (RBD) and were defined as REM sleep behavioral events (RBEs), correspond to dream enactments. 13 subjects (10 patients with Parkinson disease [PD] and 3 healthy controls) originally identified with RBE in a prospective study (DeNoPa cohort) were reinvestigated 2 years later with 2 nights of video-supported polysomnography (vPSG). The first night was used for sleep parameter analysis. During the 2nd night, subjects were awakened and questioned for dream recall and dream content when purposeful motor behaviors and/or vocalizations became evident during REM sleep. REM sleep without atonia (RWA) was analyzed on chin EMG and the cutoff set at 18.2% as specific for RBD. At the time of this investigation 9 of 13 subjects with previous RBE were identified with RBD based upon clinical and EMG criteria. All recalled vivid dreams, and 7 subjects were able to describe dream content in detail. Four of 13 subjects with RBE showed RWA values below cutoff values for RBD. Three of these 4 subjects recalled having non-threatening dreams, and 2 (of these 3) were able to describe these dreams in detail. RBE with RWA below the RBD defining criteria correlate to dreaming in this selected cohort. There is evidence that RBEs are a precursor to RBD. © 2015 American Academy of Sleep Medicine.

Rapid eye movement (REM) sleep behavior disorder (RBD) has been related to altered, action-filled, vivid, and aggressive dream content, but research comparing the possible differences in dreams of Parkinson's disease (PD) patients with and without RBD is scarce. The dream content of PD patients with and without RBD was analyzed with specific focus on action-filledness, vividness, emotional valence, and threats. A total of 69 REM and NREM dream reports were collected in the sleep laboratory, 37 from nine PD patients with RBD and 32 from six PD patients without RBD. A content analysis of (1) action-filledness (actions and environmental events); (2) vividness (emotions and cognitive activity); (3) intensity of actions, events and emotions; (4) emotional valence, and (5) threatening events was performed on the transcripts. Altogether 563 dream elements expressing action-filledness and vividness were found. There were no significant between-group differences in the number or distribution of elements reflecting action-filledness or vividness, emotional valence or threats. In within-group analyses, PD patients with RBD had significantly more negative compared to positive dreams (p = 0.012) and compared to PD patients without RBD, a tendency to have more intense actions in their dreams (p = 0.066). Based on the results of this study, there are no major between-group differences in the action-filledness, vividness, or threat content of dreams of PD patients with and without RBD. However, within-group analyses revealed that dreams were more often negatively than positively toned in PD patients with RBD. Copyright © 2014 Elsevier B.V. All rights reserved.

Beyond the neuropsychology of dreaming: Insights into the neural basis of dreaming with new techniques of sleep recording and analysis.

Recent advances in electrophysiological [e.g., surface high-density electroencephalographic (hd-EEG) and intracranial recordings], video-polysomnography (video-PSG), transcranial stimulation and neuroimaging techniques allow more in-depth and more accurate investigation of the neural correlates of dreaming in healthy individuals and in patients with brain-damage, neurodegenerative diseases, sleep disorders or parasomnias. Convergent evidence provided by studies using these techniques in healthy subjects has led to a reformulation of several unresolved issues of dream generation and recall [such as the inter- and intra-individual differences in dream recall and the predictivity of specific EEG rhythms, such as theta in rapid eye movement (REM) sleep, for dream recall] within more comprehensive models of human consciousness and its variations across sleep/wake states than the traditional models, which were largely based on the neurophysiology of REM sleep in animals. These studies are casting new light on the neural bases (in particular, the activity of dorsal medial prefrontal cortex regions and hippocampus and amygdala areas) of the inter- and intra-individual differences in dream recall, the temporal location of specific contents or properties (e.g., lucidity) of dream experience and the processing of memories accessed during sleep and incorporated into dream content. Hd-EEG techniques, used on their own or in combination with neuroimaging, appear able to provide further important insights into how the brain generates not only dreaming during sleep but also some dreamlike experiences in waking.

The genius of the dream.

Palombo, S R

In Act V of A Midsummer Night's Dream, Theseus and Hippolyta exchange views on the dreamlike adventures reported by the young lovers. Theseus dismisses their stories as fantasies of wish fulfillment, but Hippolyta points out that despite their strangeness, the tales reflect an adaptive change in the psychic reality of the lovers. The dramatic action of the play supports Hippolyta's view. The release of Demetrius from his transferential infatuation with Hermia comes at the moment of awakening from a dream in which he has matched his current feelings for Hermia with a repressed libidinal fantasy of childhood. This example of a correction dream illustrates how condensation in dreams functions adaptively in matching a new experience with previously stored representations of related events in the past. It also illustrates the ability of the matching process to go beyond the narrow logical categories of waking thought to reach deeper levels of experience otherwise inaccessible to the dreamer. This ability accounts for the important role played by dreaming in the creative process generally and in the day-to-day working-through process of psychoanalytic therapy. The adaptive function of dreaming is subject at many points to interference from the censorship mechanisms discovered and emphasized by Freud. A theory of dreaming combining these antagonistic processes is more consistent with the data of the sleep laboratory than the traditional psychoanalytic theory alone. It also provides a better fit with the introspective date more familiar to the analyst as illustrated by Freud's well-documented analysis of his own dreams.

"Determined, Resilient, AIDS-free, Mentored and Safe" (DREAMS) is a package of biomedical, social and economic interventions offered to adolescent girls and young women aged 10-24 years with the aim of reducing HIV incidence. In four of the six DREAMS districts in Zimbabwe, DREAMS includes an offer of oral pre-exposure prophylaxis (DREAMS+PrEP), alongside interventions to support demand and adherence, to women aged 18-24 who are at highest risk of HIV infection, including young women who sell sex (YWSS). This evaluation study addresses the question: does the delivery of DREAMS+PrEP through various providers reduce HIV incidence among YWSS Zimbabwe? We describe our approach to designing a rigorous study to assess whether DREAMS+PrEP had an impact on HIV incidence. The study design needed to account for the fact that: 1) DREAMS+PrEP was non-randomly allocated; 2) there is no sampling frame for the target population for the evaluation; 3) there are a small number of DREAMS districts (N = 6), and 4) DREAMS+PrEP is being implemented by various providers. The study will use a cohort analysis approach to compare HIV incidence among YWSS in two DREAMS+PrEP districts to HIV incidence among YWSS in non-DREAMS comparison sites. YWSS will be referred to services and recruited into the cohort through a network-based (respondent-driven) recruitment strategy, and followed-up 12- and 24-months after enrolment. Women will be asked to complete a questionnaire and offered HIV testing. Additional complications of this study include identifying comparable populations of YWSS in the DREAMS+PrEP and non-DREAMS comparison sites, and retention of YWSS over the 24-month period. The primary outcome is HIV incidence among YWSS HIV-negative at study enrolment measured by repeat, rapid HIV testing over 24-months. Inference will be based on plausibility that DREAMS+PrEP had an impact on HIV incidence. A process evaluation will be conducted to understand intervention implementation, and document any contextual factors determining the success or failure of intervention delivery. HIV prevention products of known efficacy are available. Innovative studies are needed to provide evidence of how to optimise product use through combination interventions to achieve population impact within different contexts. We describe the design of such a study.

Validation of sick leave measures: self-reported sick leave and sickness benefit data from a Danish national register compared to multiple workplace-registered sick leave spells in a Danish municipality

PubMed Central

2012-01-01

Background Previous validation studies of sick leave measures have focused on self-reports. Register-based sick leave data are considered to be valid; however methodological problems may be associated with such data. A Danish national register on sickness benefit (DREAM) has been widely used in sick leave research. On the basis of sick leave records from 3,554 and 2,311 eldercare workers in 14 different workplaces, the aim of this study was to: 1) validate registered sickness benefit data from DREAM against workplace-registered sick leave spells of at least 15 days; 2) validate self-reported sick leave days during one year against workplace-registered sick leave. Methods Agreement between workplace-registered sick leave and DREAM-registered sickness benefit was reported as sensitivities, specificities and positive predictive values. A receiver-operating characteristic curve and a Bland-Altman plot were used to study the concordance with sick leave duration of the first spell. By means of an analysis of agreement between self-reported and workplace-registered sick leave sensitivity and specificity was calculated. Ninety-five percent confidence intervals (95% CI) were used. Results The probability that registered DREAM data on sickness benefit agrees with workplace-registered sick leave of at least 15 days was 96.7% (95% CI: 95.6-97.6). Specificity was close to 100% (95% CI: 98.3-100). The registered DREAM data on sickness benefit overestimated the duration of sick leave spells by an average of 1.4 (SD: 3.9) weeks. Separate analysis on pregnancy-related sick leave revealed a maximum sensitivity of 20% (95% CI: 4.3-48.1). The sensitivity of self-reporting at least one or at least 56 sick leave day/s was 94.5 (95% CI: 93.4 – 95.5) % and 58.5 (95% CI: 51.1 – 65.6) % respectively. The corresponding specificities were 85.3 (95% CI: 81.4 – 88.6) % and 98.9 (95% CI: 98.3 – 99.3) %. Conclusions The DREAM register offered valid measures of sick leave spells of at least 15 days among eldercare employees. Pregnancy-related sick leave should be excluded in studies planning to use DREAM data on sickness benefit. Self-reported sick leave became more imprecise when number of absence days increased, but the sensitivity and specificity were acceptable for lengths not exceeding one week. PMID:22894644

Calibration of terrestrial ecosystem models is important but challenging. Bayesian inference implemented by Markov chain Monte Carlo (MCMC) sampling provides a comprehensive framework to estimate model parameters and associated uncertainties using their posterior distributions. The effectiveness and efficiency of the method strongly depend on the MCMC algorithm used. In this study, a Differential Evolution Adaptive Metropolis (DREAM) algorithm was used to estimate posterior distributions of 21 parameters for the data assimilation linked ecosystem carbon (DALEC) model using 14 years of daily net ecosystem exchange data collected at the Harvard Forest Environmental Measurement Site eddy-flux tower. The DREAM is a multi-chainmore » method and uses differential evolution technique for chain movement, allowing it to be efficiently applied to high-dimensional problems, and can reliably estimate heavy-tailed and multimodal distributions that are difficult for single-chain schemes using a Gaussian proposal distribution. The results were evaluated against the popular Adaptive Metropolis (AM) scheme. DREAM indicated that two parameters controlling autumn phenology have multiple modes in their posterior distributions while AM only identified one mode. The calibration of DREAM resulted in a better model fit and predictive performance compared to the AM. DREAM provides means for a good exploration of the posterior distributions of model parameters. Lastly, it reduces the risk of false convergence to a local optimum and potentially improves the predictive performance of the calibrated model.« less

The purpose of this paper is to demonstrate the unique place of understanding and interpreting dreams in the psychoanalytic process while working through developmental trauma. This psychoanalytic process extended over six years and is presented in four phases: establishing the therapeutic alliance, a crisis, working through, and termination. Dreams from each of these four phases of the analysis are presented, and the collaborative work of understanding and interpreting these dreams is highlighted. Evidence is presented that from this analytic work there ensued an amelioration of the impact of developmental trauma and a furtherance of the development of internal psychic structure. © 2016 by the American Psychoanalytic Association.

End-of-life dreams and visions (ELDVs) are well documented throughout history and across cultures with impact on the dying person and their loved ones having profound meaning. Published studies on ELDVs are primarily based on surveys or interviews with clinicians or families of dead persons. This study uniquely examined patient dreams and visions from their personal perspective. This article reports the qualitative findings from dreams and visions of 63 hospice patients. Inductive content analysis was used to examine the content and subjective significance of ELDVs. Six categories emerged: comforting presence, preparing to go, watching or engaging with the deceased, loved ones waiting, distressing experiences, and unfinished business. © The Author(s) 2014.

Dermal Exposure Assessment to Pesticides in Farming Systems in Developing Countries: Comparison of Models

In the field of occupational hygiene, researchers have been working on developing appropriate methods to estimate human exposure to pesticides in order to assess the risk and therefore to take the due decisions to improve the pesticide management process and reduce the health risks. This paper evaluates dermal exposure models to find the most appropriate. Eight models (i.e., COSHH, DERM, DREAM, EASE, PHED, RISKOFDERM, STOFFENMANAGER and PFAM) were evaluated according to a multi-criteria analysis and from these results five models (i.e., DERM, DREAM, PHED, RISKOFDERM and PFAM) were selected for the assessment of dermal exposure in the case study of the potato farming system in the Andean highlands of Vereda La Hoya, Colombia. The results show that the models provide different dermal exposure estimations which are not comparable. However, because of the simplicity of the algorithm and the specificity of the determinants, the DERM, DREAM and PFAM models were found to be the most appropriate although their estimations might be more accurate if specific determinants are included for the case studies in developing countries.

The termination phase of psychoanalysis as seen through the lens of the dream.

PubMed

Grenell, Gary

2002-01-01

The decision about when to terminate analysis has long been underpinned by a theory-driven criterion model, which may steer the analytic dialogue away from its customary activities of free association, empathic listening, and interpretation. As a remedy to this situation, the author proposes that by paying careful attention to less consciously crafted patient communications such as dreams, the analytic dyad can consider readiness to set a termination date from a perspective that is context-sensitive and less encumbered by preordained criteria. Tracing the dreams of one analysand from the vantage point of contemporary dream theory, the author demonstrates how careful attention to the dream elucidated the patient's readiness to terminate and her complex feelings about the termination process. Finally, the author challenges the notion that the termination phase is of greater evaluative than therapeutic importance, and provides clinical material as evidence that this is not the case.

Study Objectives: To assess prospectively the emotional content of dreams in individuals with the obstructive sleep apnea hypopnea syndrome (OSAHS) and sleepy snorers. Methods: Prospective observational study. Forty-seven patients with sleepiness and snoring attending a sleep-disordered breathing clinic, completed a morning diary concerning pleasantness/unpleasantness of their dreams for 10 days, and then had AHI assessed by a limited-channel home sleep study. Participants and groups: Sleepy snorers, AHI < 5: n = 12 (mean age = 51.00 years [SD 7.01], 7 males); AHI 5 −14.9, n = 14 (mean age = 49.71 y [9.73], 12 males); AHI ≥ 15, n = 21 (mean age = 56.33 [11.24], 16 males). Results: All groups reported similar numbers of dreams and nightmares during the diary period. The AHI ≥ 15 group were significantly higher on dream unpleasantness than were the sleepy snorers (p < 0.05); and when only males were analyzed, this difference was also significant (p = 0.01). As AHI increased across the 3 groups, there was a significant decrease in variability of dream emotions (Levene test for homogeneity of variance between the 3 groups, p = 0.018). Mean daytime anxiety and daytime depression were significantly correlated with mean dream unpleasantness and with mean number of nightmares over the diary period. Conclusions: Patients with AHI ≥ 15 had more emotionally negative dreams than patients with AHI < 5. The variation in mean dream emotion decreased with increasing AHI, possibly because sleep fragmentation with increasing AHI results in fewer and shorter dreams, in which emotions are rarer.

The importance of dreams and action in the adolescent process.

PubMed

Ladame, F

1995-12-01

The author argues that after puberty dreams and action are indicators of the capacity of the psychic apparatus to perform the work of binding drive energy. He notes that the development of adult sexuality always involves risk and that effective dream activity affords a definitive solution to the problem of incestuous and parricidal temptations, which attain an unprecedented pitch of intensity with the onset of sexual and procreative potency in adolescence. The author illustrates his thesis by the case of an adolescent patient with particular sexual pathology who broke down at the age of 17 and who, once he became able to dream in the course of analysis, had less need to act out. A 'work of the negative' is presented as a paradoxical but important element in psychic development. Dreaming and action are stated to be inseparable and to constitute an essential safety valve that facilitates the developmental process. A discussion of the connections between dreams and initiation leads to some ethnological considerations on sexuality and society, and the paper ends with a plea not to overlook the death drive.

Dreams that mirror the session.

PubMed

Civitarese, Giuseppe

2006-06-01

Dreams in which the analyst appears undisguised almost always depict violations of the setting. Often experienced as special, epiphanic moments, they give a glimpse of an intense, emotional reaction to traumatogenic or otherwise significant events that have occurred during the session or in the most recent previous ones. Probably, the essential aspect of these dreams can be found in the 'form of their content'. This may be paralleled by the narrative technique of mise en abyme or mirror-text. The dream appears as a story within the main story and the scene of the analysis is reflected anti-illusionistically. The fictional structure of the setting is emphasized. Its theatrical self-consciousness quality is revealed at its best. The author postulates that the transformative therapeutic value of these dreams derives from denouncing the referential illusion of 'concrete reality' and of 'what really happened'. For the analysand, they are an effective (i.e. emotionally intense) opportunity to discover the spatial articulations and the staggering refractions of the inside/outside, the textual/extra-textual, the psychic reality/material reality. In the continual comings and goings from one term to another, the work of symbolization is reactivated and the subject is constructed. Dreams that mirror the session, from this point of view, provide a model for conceptualizing the analytic work, and their significance goes beyond the specific phenomena referred to. A clinical case is given, in which some of one patient's dreams are considered as they occurred over a short period. In one of them, the dream-within-a-dream phenomenon is present.

To evaluate the frequency, determinants and sleep characteristics of lucid dreaming in narcolepsy. University hospital sleep disorder unit. Case-control study. Consecutive patients with narcolepsy and healthy controls. Participants were interviewed regarding the frequency and determinants of lucid dreaming. Twelve narcolepsy patients and 5 controls who self-identified as frequent lucid dreamers underwent nighttime and daytime sleep monitoring after being given instructions regarding how to give an eye signal when lucid. Compared to 53 healthy controls, the 53 narcolepsy patients reported more frequent dream recall, nightmares and recurrent dreams. Lucid dreaming was achieved by 77.4% of narcoleptic patients and 49.1% of controls (P < 0.05), with an average of 7.6±11 vs. 0.3±0.8 lucid dreams/ month (P < 0.0001). The frequency of cataplexy, hallucinations, sleep paralysis, dyssomnia, HLA positivity, and the severity of sleepiness were similar in narcolepsy with and without lucid dreaming. Seven of 12 narcoleptic (and 0 non-narcoleptic) lucid dreamers achieved lucid REM sleep across a total of 33 naps, including 14 episodes with eye signal. The delta power in the electrode average, in delta, theta, and alpha powers in C4, and coherences between frontal electrodes were lower in lucid than non-lucid REM sleep in spectral EEG analysis. The duration of REM sleep was longer, the REM sleep onset latency tended to be shorter, and the percentage of atonia tended to be higher in lucid vs. non-lucid REM sleep; the arousal index and REM density and amplitude were unchanged. Narcolepsy is a novel, easy model for studying lucid dreaming. © 2015 Associated Professional Sleep Societies, LLC.

Background. Migraineurs brain has shown some functional peculiarities that reflect not only in phonophobia, and photophobia, but also in mood and sleep. Dreaming is a universal mental state characterized by hallucinatory features in which imagery, emotion, motor skills, and memory are created de novo. We evaluated dream contents and associated emotions in migraineurs. Materials and Methods. 412 subjects: 219 controls; and 148 migraineurs (66 with aura, MA; 82 without aura, MO), and 45 tension type headache patients (TTH). A semistructured retrospective self-reported questionnaire was used to evaluate dreams. The Generalized Anxiety Disorder Questionnaire (GAD-7), and the Patient Health Questionnaire (PHQ-9) were administered to evaluate anxiety and depression. Results. Migraineurs showed increased levels of anxiety (P = 0.0002 for MA versus controls, P = 0.004 for MO versus controls). Fear and anguish during dreaming were more frequently reported by migraine patients compared to controls, independently by anxiety and depression scores. Discussion. The brain of migraineurs seems to dream with some peculiar features, all with a negative connotation, as fear and anguish. It may be due to the recorded negative sensations induced by recurrent migraine pain, but it may just reflect a peculiar attitude of the mesolimbic structures of migraineurs brain, activated in both dreaming and migraine attacks.

The Experience Elicited by Hallucinogens Presents the Highest Similarity to Dreaming within a Large Database of Psychoactive Substance Reports.

PubMed

Sanz, Camila; Tagliazucchi, Enzo

2018-01-01

Ever since the modern rediscovery of psychedelic substances by Western society, several authors have independently proposed that their effects bear a high resemblance to the dreams and dreamlike experiences occurring naturally during the sleep-wake cycle. Recent studies in humans have provided neurophysiological evidence supporting this hypothesis. However, a rigorous comparative analysis of the phenomenology ("what it feels like" to experience these states) is currently lacking. We investigated the semantic similarity between a large number of subjective reports of psychoactive substances and reports of high/low lucidity dreams, and found that the highest-ranking substance in terms of the similarity to high lucidity dreams was the serotonergic psychedelic lysergic acid diethylamide (LSD), whereas the highest-ranking in terms of the similarity to dreams of low lucidity were plants of the Datura genus, rich in deliriant tropane alkaloids. Conversely, sedatives, stimulants, antipsychotics, and antidepressants comprised most of the lowest-ranking substances. An analysis of the most frequent words in the subjective reports of dreams and hallucinogens revealed that terms associated with perception ("see," "visual," "face," "reality," "color"), emotion ("fear"), setting ("outside," "inside," "street," "front," "behind") and relatives ("mom," "dad," "brother," "parent," "family") were the most prevalent across both experiences. In summary, we applied novel quantitative analyses to a large volume of empirical data to confirm the hypothesis that, among all psychoactive substances, hallucinogen drugs elicit experiences with the highest semantic similarity to those of dreams. Our results and the associated methodological developments open the way to study the comparative phenomenology of different altered states of consciousness and its relationship with non-invasive measurements of brain physiology.

The sense of the body in the dream: Diagnostic capacity in the meanings of dreams.

PubMed

Giordo, Gianfranco

2016-04-01

The author investigates the oneiric representation of somatic states and the diagnostic capacity of dreams. He draws on Freud's hypotheses on the procedures by which somatic stimuli insert themselves in oneiric elaboration and restructures them according to the recent neurobiological discoveries and to analytical experiences. In the representations of certain dreams, with a psychic interpretation agreed upon by the patients, somatic alterations unknown to the analytical couple were discriminated and confirmed by radiological investigations. These representations were linked to the manifestation of one aspect of the bodily Self, neglected in the precocious maternal relation, that entered the organization of the Self consolidated in the relation with the paternal figure. This conjunction gave origin to the double meaning (somatic and psychic) of the dream. The entering of the somatic representation in the oneiric one did not appear to be the figurative effect, but of a condensation of diagnostic capacity into the meaning of the dream. This characteristic manifested itself in the particular styles of the dreamers, interpretable by an analyst countertransferentially oriented. The perception or scotomization of the condensation in the interpretation of the dream and of the moment had an effect on the evolution of the analysis. Copyright © 2015 Institute of Psychoanalysis.

Dream-reality confusion in borderline personality disorder: a theoretical analysis

PubMed Central

Skrzypińska, Dagna; Szmigielska, Barbara

2015-01-01

This paper presents an analysis of dream-reality confusion (DRC) in relation to the characteristics of borderline personality disorder (BPD), based on research findings and theoretical considerations. It is hypothesized that people with BPD are more likely to experience DRC compared to people in non-clinical population. Several variables related to this hypothesis were identified through a theoretical analysis of the scientific literature. Sleep disturbances: problems with sleep are found in 15–95.5% of people with BPD (Hafizi, 2013), and unstable sleep and wake cycles, which occur in BPD (Fleischer et al., 2012), are linked to DRC. Dissociation: nearly two-thirds of people with BPD experience dissociative symptoms (Korzekwa and Pain, 2009) and dissociative symptoms are correlated with a fantasy proneness; both dissociative symptoms and fantasy proneness are related to DRC (Giesbrecht and Merckelbach, 2006). Negative dream content: People with BPD have nightmares more often than other people (Semiz et al., 2008); dreams that are more likely to be confused with reality tend to be more realistic and unpleasant, and are reflected in waking behavior (Rassin et al., 2001). Cognitive disturbances: Many BPD patients experience various cognitive disturbances, including problems with reality testing (Fiqueierdo, 2006; Mosquera et al., 2011), which can foster DRC. Thin boundaries: People with thin boundaries are more prone to DRC than people with thick boundaries, and people with BPD tend to have thin boundaries (Hartmann, 2011). The theoretical analysis on the basis of these findings suggests that people who suffer from BPD may be more susceptible to confusing dream content with actual waking events. PMID:26441768

6 patients with itching due to skin disorder and 6 student controls were studied in the sleep laboratory. It was found that some of the patients had personality characteristics consistent with Sifneos' concept of alexithymia and that these were associated with a trend towards less REM sleep and with a significant lack of involvement in dreams collected under standardised sleep laboratory conditions. It is suggested that dreams collection in a sleep laboratory may be a valuable new method in the study of the link between emotional life and psychosomatic disorders.

Using the dream journal methodology, 86 participants reported occurrence of dreams, dream content, and ratings of affect and drug craving. The relationships between the experience of DD, dream content ("active" vs "passive"), and affect and craving were analyzed using mixed model methods. The experience of DD was associated with higher levels of negative affect (P < 0.001) and craving (P < 0.001). The occurrence of DD did not decrease significantly over the 5 weeks of the study. Cocaine/crack users reported a higher occurrence of DD (P < 0.05) than the other drug groups (opiates and alcohol), and DD involving "active" drug use was associated with larger (P < 0.05) changes in negative affect. These results are consistent with the hypothesis that DD can act as drug-conditioned stimuli to elevate negative affect and craving in abstaining individuals. Although correlational, such findings support the implementation of psychological and pharmacological interventions aimed at minimizing the impact of DD on individuals in recovery from drug addiction.

'Clemency on the way to the gallows': death, dreams and dissociation.

PubMed

Kimmel, Kenneth

2017-11-01

The survivor of a decade of childhood sexual trauma and violence, perpetrated by a monstrous father, produced a series of dreams in the final year of a ten-year analysis. They illuminated the 'death drive' beneath a lifelong preoccupation with dying and fantasies of submission to death, perpetuated by the promise of hoped-for freedom from pain and release from a life of suffering. The initial dream involved the collapse of a team of white horses drawing him in a pillory cart to his own hanging for a crime he did not commit. It signified the collapse of a fragile psychological system based on his role as the 'sacrificial lamb,' protecting a (not so) innocent mother. The raw truth was now unconcealed: primal, violent, and terrifying dreams and affects emerged where he was now the murderous aggressor. His dreams would become primary agents for an instinctive, life-giving authenticity to emerge, offering him clemency from the shattering repetitions of persecution and dissociation. © 2017, The Society of Analytical Psychology.

Phenomenological features of dreams: Results from dream log studies using the Subjective Experiences Rating Scale (SERS).

PubMed

Kahan, Tracey L; Claudatos, Stephanie

2016-04-01

Self-ratings of dream experiences were obtained from 144 college women for 788 dreams, using the Subjective Experiences Rating Scale (SERS). Consistent with past studies, dreams were characterized by a greater prevalence of vision, audition, and movement than smell, touch, or taste, by both positive and negative emotion, and by a range of cognitive processes. A Principal Components Analysis of SERS ratings revealed ten subscales: four sensory, three affective, one cognitive, and two structural (events/actions, locations). Correlations (Pearson r) among subscale means showed a stronger relationship among the process-oriented features (sensory, cognitive, affective) than between the process-oriented and content-centered (structural) features--a pattern predicted from past research (e.g., Bulkeley & Kahan, 2008). Notably, cognition and positive emotion were associated with a greater number of other phenomenal features than was negative emotion; these findings are consistent with studies of the qualitative features of waking autobiographical memory (e.g., Fredrickson, 2001).

[Artistic dream reconstructions of the Wolf Man in the light of experimental findings].

PubMed

Leuschner, W; Hau, S

1995-07-01

The authors take the famous dream picture by the "wolf-man" as the starting-point for experimental research of their own and relate the one to the other. They see the significance of pictorial representations of dreams less in the supplementary information they convey about the "text" of dreams than in the fact that they give separate expression to motility-based "gesture-associated" memories and ideas. These need to be distinguished from "language-associated" memories as there are dissociated modes of encoding experience underlying verbal and pictorial representation. The splitting of these modes into different part-codes is an important component of repression. In addition, the pictorial representation of dreams enables the patient to re-associate part-codes and thus achieve a "deferred" reconstruction and complementation of significant experiences. In the authors view, pictorial representation is favorable to the discovery of repressed material; it is as yet however impossible to say exactly what relationship there is between verbalized and pictorial representation in the context of analysis.

Extending the Rorschach trauma content index and aggression indexes to dream narratives of children exposed to enduring violence: an exploratory study.

PubMed

Kamphuis, Jan H; Tuin, Nynke; Timmermans, Marieke; Punamäki, Raija-Leena

2008-11-01

In this study, we compared dream narratives of children and adolescents living under conditions of enduring interpersonal violence (n = 220) versus those living in peaceful surroundings (n = 99) on content variables that have been associated with traumatic experiences in Rorschach (Exner, 1995) imagery. As predicted, children and adolescents living in circumstances of enduring violence reported a higher proportion of content scorable by Armstrong and Loewenstein's (1990) Trauma Content Index and a much higher proportion of aggressive objects in their dreams (AgC; Gacono & Meloy, 1994). In support of discriminant validity, no consistent group differences were observed for the relative frequencies of Animal (A), Clothing (Cg), or Cooperative movement (COP) content. The modest association between manifest dream content and psychological symptom scales suggests that the former may alternatively reflect adaptive or psychopathological processes. Our findings suggest that content analysis of dreams may be a valuable adjunct in tapping the psychological state of children traumatized by violence.

Dreams and Psychedelics: Neurophenomenological Comparison and Therapeutic Implications

PubMed Central

Kraehenmann, Rainer

2017-01-01

Background: A resurgence of neurobiological and clinical research is currently underway into the therapeutic potential of serotonergic or ‘classical’ psychedelics such as the prototypical psychedelic drug lysergic acid diethylamide (LSD) psilocybin (4-phosphoryloxy-N,N-dimethyltryptamine) and ayahuasca – a betacarboline- and dimethyltryptamine (DMT)-containing Amazonian beverage. The aim of this review is to introduce readers to the similarities and dissimilarities between psychedelic states and night dreams and to draw conclusions related to therapeutic applications of psychedelics in psychiatry. Methods: Research literature related to psychedelics and dreaming is reviewed and these two states of consciousness are systematically compared. Relevant conclusions with regard to psychedelic-assisted therapy will be provided. Results: Common features between psychedelic states and night dreams include perception mental imagery emotion activation fear memory extinction and sense of self and body. Differences between these two states are related to differential perceptual input from the environment clarity of consciousness and meta-cognitive abilities. Therefore psychedelic states are closest to lucid dreaming which is characterized by a mixed state of dreaming and waking consciousness Conclusion: The broad overlap between dreaming and psychedelic states supports the notion that psychedelics acutely induce dreamlike subjective experiences which may have long-term beneficial effects on psychosocial functioning and well-being. Future clinical studies should examine how therapeutic outcome is related to the acute dreamlike effects of psychedelics. PMID:28625125

Objective To characterize parasomnia behaviors on arousal from NREM sleep in Parkinson’s Disease (PD) and Multiple System Atrophy (MSA). Methods From 30 patients with PD, Dementia with Lewy Bodies/Dementia associated with PD, or MSA undergoing nocturnal video-polysomnography for presumed dream enactment behavior, we were able to select 2 PD and 2 MSA patients featuring NREM Parasomnia Behviors (NPBs). We identified episodes during which the subjects seemed to enact dreams or presumed dream-like mentation (NPB arousals) versus episodes with physiological movements (no-NPB arousals). A time-frequency analysis (Morlet Wavelet Transform) of the scalp EEG signals around each NPB and no- NPB arousal onset was performed, and the amplitudes of the spectral frequencies were compared between NPB and no-NPB arousals. Results 19 NPBs were identified, 12 of which consisting of ‘elementary’ NPBs while 7 resembling confusional arousals. With quantitative EEG analysis, we found an amplitude reduction in the 5-6 Hz band 40 seconds before NPBs arousal as compared to no-NPB arousals at F4 and C4 derivations (p<0.01). Conclusions Many PD and MSA patients feature various NREM sleep-related behaviors, with clinical and electrophysiological differences and similarities with arousal parasomnias in the general population. Significance This study help bring to attention an overlooked phenomenon in neurodegenerative diseases. PMID:25756280

Bearing the unbearable: ancestral transmission through dreams and moving metaphors in the analtyic field.

PubMed

Pickering, Judith

2012-11-01

This paper explores how untold and unresolved intergenerational trauma may be transmitted through unconscious channels of communication, manifesting in the dreams of descendants. Unwitting carriers for that which was too horrific for their ancestors to bear, descendants may enter analysis through an unconscious need to uncover past secrets, piece together ancestral histories before the keys to comprehending their terrible inheritance die with their forebears. They seek the relational containment of the analytic relationship to provide psychological conditions to bear the unbearable, know the unknowable, speak the unspeakable and redeem the unredeemable. In the case of 'Rachael', initial dreams gave rise to what Hobson (1984) called 'moving metaphors of self' in the analytic field. Dream imagery, projective and introjective processes in the transference-countertransference dynamics gradually revealed an unknown ancestral history. I clarify the back and forth process from dream to waking dream thoughts to moving metaphors and differentiate the moving metaphor from a living symbol. I argue that the containment of the analytic relationship nested within the security of the analytic space is a necessary precondition for such healing processes to occur. © 2012, The Society of Analytical Psychology.

Comparing the effects of real versus simulated violence on dream imagery.

2014-08-01

Participants in the current study were 75 males, including 25 Canadian soldiers, 25 heavy gamers who play military based video games such as "Call of Duty," and a control group comprised of 25 males. One dream per participant was analyzed using Hall and Van de Castle content analysis guidelines, including aggression, threat, and previously established scales for intensity of aggression and emotion. The dreams of soldiers had a higher frequency of both aggression and threat, and were also more intense in aggression and emotion than both the heavy gamers and the controls. These findings suggest that exposure to real life violence and threat (as well as the emotional significance of the experience) is more frequently incorporated into dream imagery than simulated or virtual threat. Limitations and directions for future studies are discussed.

A pilot study for the analysis of dream reports using Maslow's need categories: an extension to the emotional selection hypothesis.

PubMed

Coutts, Richard

2010-10-01

The emotional selection hypothesis describes a cyclical process that uses dreams to modify and test select mental schemas. An extension is proposed that further characterizes these schemas as facilitators of human need satisfaction. A pilot study was conducted in which this hypothesis was tested by assigning 100 dream reports (10 randomly selected from 10 dream logs at an online web site) to one or more categories within Maslow's hierarchy of needs. A "match" was declared when at least two of three judges agreed both for category and for whether the identified need was satisfied or thwarted in the dream narrative. The interjudge reliability of the judged needs was good (92% of the reports contained at least one match). The number of needs judged as thwarted did not differ significantly from the number judged as satisfied (48 vs. 52%, respectively). The six "higher" needs (belongingness, esteem, cognitive, aesthetic, self-actualization, and transcendence) were scored significantly more frequently (81%) than were the two lowest or "basic" needs (physiological and safety, 19%). Basic needs were also more likely to be judged as thwarted, while higher needs were more likely to be judged as satisfied. These findings are discussed in the context of Maslow's hierarchy of needs as a framework for investigating theories of dream function, including the emotional selection hypothesis and other contemporary dream theories.

Although sedation is often performed during spinal anesthesia, the details of intraoperative dreaming have not been reported. We designed this prospective study to compare 2 different IV sedation protocols (propofol and midazolam infusion) with respect to dreaming during sedation. Two hundred twenty adult patients were randomly assigned to 2 groups and received IV infusion of propofol or midazolam for deep sedation during spinal anesthesia. Patients were interviewed on emergence and 30 minutes later to determine the incidence, content, and nature of their dreams. Postoperatively, patient satisfaction with the sedation was also evaluated. Two hundred fifteen patients (108 and 107 in the propofol and midazolam groups, respectively) were included in the final analysis. The proportion of dreamers was 39.8% (43/108) in the propofol group and 12.1% (13/107) in the midazolam group (odds ratio=4.78; 95% confidence interval: 2.38 to 9.60). Dreams of the patients receiving propofol were more memorable and visually vivid than were those of the patients receiving midazolam infusion. The majority of dreams (36 of 56 dreamers, 64.3%) were simple, pleasant ruminations about everyday life. A similarly high level of satisfaction with the sedation was observed in both groups. In cases of spinal anesthesia with deep sedation, dreaming was almost 5 times more common in patients receiving propofol infusion than in those receiving midazolam, although this did not influence satisfaction with the sedation. Thus, one does not need to consider intraoperative dreaming when choosing propofol or midazolam as a sedative drug in patients undergoing spinal anesthesia. © 2011 International Anesthesia Research Society

Trait and neurobiological correlates of individual differences in dream recall and dream content.

PubMed

Blagrove, Mark; Pace-Schott, Edward F

2010-01-01

Individuals differ greatly in their dream recall frequency, in their incidence of recalling types of dreams, such as nightmares, and in the content of their dreams. This chapter reviews work on the waking life correlates of these differences between people in their experience of dreaming and reviews some of the neurobiological correlates of these individual differences. The chapter concludes that despite there being trait-like aspects of general dream recall and of dream content, very few psychometrically assessed correlates for dream recall frequency and dream content have been found. More successful has been the investigation of correlates of frequency of particular types of dreams, such as nightmares and lucid dreams, and also of how waking-life experience is associated with dream content. There is also potential in establishing neurobiological correlates of individual differences in dream recall and dream content, and recent work on this is reviewed. Copyright © 2010 Elsevier Inc.

What physicians need to know about dreams and dreaming.

PubMed

Pagel, James F

2012-11-01

An overview of the current status of dream science is given, designed to provide a basic background of this field for the sleep-interested physician. No cognitive state has been more extensively studied and is yet more misunderstood than dreaming. Much older work is methodologically limited by lack of definitions, small sample size, and constraints of theoretical perspective, with evidence equivocal as to whether any special relationship exists between rapid eye movement (REM) sleep and dreaming. As the relationship between dreams and REM sleep is so poorly defined, evidence-based studies of dreaming require a dream report. The different aspects of dreaming that can be studied include dream and nightmare recall frequency, dream content, dreaming effect on waking behaviors, dream/nightmare associated medications, and pathophysiology affecting dreaming. Whether studied from behavioral, neuroanatomical, neurochemical, pathophysiological or electrophysiological perspectives, dreaming reveals itself to be a complex cognitive state affected by a wide variety of medical, psychological, sleep and social variables.

Dream recall and dream content in children with attention deficit/hyperactivity disorder.

PubMed

Schredl, Michael; Sartorius, Heiko

2010-04-01

Although sleep is widely investigated in children with ADHD, dream studies in this group are completely lacking. The continuity hypothesis of dreaming stating that waking life is reflected in dreams would predict that waking-life symptoms are reflected in the dreams of such children. 103 children with ADHD and 100 controls completed a dream questionnaire eliciting dream recall frequency and the most recent dream. The dreams of the children with ADHD did not show a heightened occurrence of activities but were more negatively toned and included more misfortunes/threats, negative endings, and physical aggression towards the dreamer. Dream recall frequency and general dream characteristics like dream length and dream bizarreness did not differ from children without ADHD. The dreams seem to reflect the inner world of the child with ADHD. From a clinical point of view, it would be very interesting to study whether the negatively toned dreams change during treatment (pharmacological and/or psychotherapeutic) in a way similar to how sleep quality improves.

The validity of using Gaussian assumptions for model residuals in uncertainty quantification of a groundwater reactive transport model was evaluated in this study. Least squares regression methods explicitly assume Gaussian residuals, and the assumption leads to Gaussian likelihood functions, model parameters, and model predictions. While the Bayesian methods do not explicitly require the Gaussian assumption, Gaussian residuals are widely used. This paper shows that the residuals of the reactive transport model are non-Gaussian, heteroscedastic, and correlated in time; characterizing them requires using a generalized likelihood function such as the formal generalized likelihood function developed by Schoups and Vrugt (2010). For the surface complexation model considered in this study for simulating uranium reactive transport in groundwater, parametric uncertainty is quantified using the least squares regression methods and Bayesian methods with both Gaussian and formal generalized likelihood functions. While the least squares methods and Bayesian methods with Gaussian likelihood function produce similar Gaussian parameter distributions, the parameter distributions of Bayesian uncertainty quantification using the formal generalized likelihood function are non-Gaussian. In addition, predictive performance of formal generalized likelihood function is superior to that of least squares regression and Bayesian methods with Gaussian likelihood function. The Bayesian uncertainty quantification is conducted using the differential evolution adaptive metropolis (DREAM(zs)) algorithm; as a Markov chain Monte Carlo (MCMC) method, it is a robust tool for quantifying uncertainty in groundwater reactive transport models. For the surface complexation model, the regression-based local sensitivity analysis and Morris- and DREAM(ZS)-based global sensitivity analysis yield almost identical ranking of parameter importance. The uncertainty analysis may help select appropriate likelihood functions, improve model calibration, and reduce predictive uncertainty in other groundwater reactive transport and environmental modeling.

Gradiva: freud, fetishism, and Pompeian Fantasy.

PubMed

Fletcher, John

2013-10-01

This paper is a critical reconsideration of Freud's analysis (1907) of Wilhelm Jensen's novella Gradiva: A Pompeian Fantasy (1903). Freud's interest was aroused by the parallels between Jensen's presentation of dreams and Freud's model of dream formation just published in The Interpretation of Dreams (1900). Freud also acclaims Jensen's presentation of the formation and "cure" of his protagonist's delusion about a marble bas-relief of a woman walking. This paper argues for the centrality of the phenomenon of fetishism, briefly considered but excluded from Freud's analysis. The fantasy of Gradiva as "the necessary conditions for loving" (Freud 1910, pp. 165-166) is also a key thesis of the essay, which makes use of the newly translated Freud-Jensen correspondence contained in this article's Appendix. © 2013 The Psychoanalytic Quarterly, Inc.

Retrospective dream components endorsed on the KJP Dream Inventory were correlated with those on the Short Test of Musical Preference for 68 graduate students in counseling psychology (11 men). Among 40 correlations, 6 were significant between preferences for Heavy Metal and Dissociative avoidance dreams (.32), Dreaming that you are dreaming (.40), Dreaming that you have fallen unconscious or asleep (.41), Recurring pleasantness (.31), and Awakening abruptly from a dream (-.31); between preferences for Rap/Hip-Hop and Sexual dreams (.27); and between preferences for Jazz and Recurring pleasantness in dreams (.33). Subjects preferring Classical music reported a higher incidence of Dreams of flying (.33) and rated higher Discontentedness in dreams (-.26). The meaning of these low values awaits research based on personality inventories and full dream reports.

A poem and a dream.

Mahon, Eugene

2007-01-01

Recently, a journalist in analysis had a dream that stimulated the writing of a poem, the two psychic products occurring no more than a few hours apart. Since the analysand had copious free associations to both products, believing both to be culled from the same unconscious raw material, an interesting study of an act of aesthetic creation almost in statu nascendi became possible. A concept called poem work is entertained in this paper and is compared and contrasted with the classical psychoanalytic concept of dream work, allowing some unanswerable questions to be posed and discussed in regard to the formal constitutive elements of poetry.

The Experience Elicited by Hallucinogens Presents the Highest Similarity to Dreaming within a Large Database of Psychoactive Substance Reports

2018-01-01

Ever since the modern rediscovery of psychedelic substances by Western society, several authors have independently proposed that their effects bear a high resemblance to the dreams and dreamlike experiences occurring naturally during the sleep-wake cycle. Recent studies in humans have provided neurophysiological evidence supporting this hypothesis. However, a rigorous comparative analysis of the phenomenology (“what it feels like” to experience these states) is currently lacking. We investigated the semantic similarity between a large number of subjective reports of psychoactive substances and reports of high/low lucidity dreams, and found that the highest-ranking substance in terms of the similarity to high lucidity dreams was the serotonergic psychedelic lysergic acid diethylamide (LSD), whereas the highest-ranking in terms of the similarity to dreams of low lucidity were plants of the Datura genus, rich in deliriant tropane alkaloids. Conversely, sedatives, stimulants, antipsychotics, and antidepressants comprised most of the lowest-ranking substances. An analysis of the most frequent words in the subjective reports of dreams and hallucinogens revealed that terms associated with perception (“see,” “visual,” “face,” “reality,” “color”), emotion (“fear”), setting (“outside,” “inside,” “street,” “front,” “behind”) and relatives (“mom,” “dad,” “brother,” “parent,” “family”) were the most prevalent across both experiences. In summary, we applied novel quantitative analyses to a large volume of empirical data to confirm the hypothesis that, among all psychoactive substances, hallucinogen drugs elicit experiences with the highest semantic similarity to those of dreams. Our results and the associated methodological developments open the way to study the comparative phenomenology of different altered states of consciousness and its relationship with non-invasive measurements of brain physiology.

[Generation and functions of dreams].

PubMed

Medrano-Martínez, Pablo; Ramos-Platón, M José

2014-10-16

Over the last decade an ever-increasing number of articles have been published on dreams, which reflects the interest that several fields of neuroscience have in the topic. In this work we review the main scientific theories that have contributed to the body of knowledge on how they are produced and what function they serve. The article discusses the evolution of their scientific study, following a neurophysiological and neurocognitive approach. The first of these two methods seeks to determine the neurobiological mechanisms that generate them and the brain structures involved, while the second considers dreams to be a kind of cognition interacting with that of wake-fulness. Several different hypotheses about the function of dreams are examined, and more particularly those in which they are attributed with a role in the consolidation of memory and the regulation of emotional states. Although the exact mechanism underlying the generation of dreams has not been determined, neurobiological data highlight the importance of the pontine nuclei of the brainstem, several memory systems, the limbic system and the brain reward system and a number of neocortical areas. Neurocognitive data underline the relation between the cognitive and emotional processing that occurs during wakefulness and during sleep, as well as the influence of the surroundings on the content of dreams. With regard to their function, one point to be stressed is their adaptive value, since they contribute to the reprocessing of the information acquired in wakefulness and the control of the emotions. This suggests that dreams participate in the development of the cognitive capabilities.

The current study examines the Dream in midlife women and its impact on mental health functioning. Ninety midlife women filled out a questionnaire examining Dream Status, Dream Success, Dream Content, and Dream Support, as well as mental health factors of depression, anxiety, and purpose-in-life. Neither early nor current Dream Status was not found to be significantly related to mental health factors. Partial support was found for the hypothesis that Dream Success is related to mental health factors. Early Dream Content related to career and current Dream Content related to both marriage/intimacy and career are related to positive performance on mental health factors. Dream Support is positively related both to Dream Success and to mental health factors while resistance to the Dream is not. The results are discussed in light of gender differences in the developmental function and impact of the Dream.

Dreaming of you: client and therapist dreams about each other during psychodynamic psychotherapy.

2014-01-01

Our objectives were to describe the frequency of therapists' dreams about their clients and clients' dreams about their therapists, to determine how therapists and clients who had such dreams differed from those who did not have such dreams, whether therapy process and outcome differed for those who had and did not have such dreams, and to describe the content and consequences of these dreams. Thirteen doctoral student therapists conducted psychodynamic psychotherapy with 63 clients in a community clinic. Therapists who had dreams about clients had higher estimated and actual dream recall than did therapists who did not dream about clients. Qualitative analyses indicated that therapists' dreams yielded insights about the therapist, clients, and therapy; therapists used insights in their work with the clients. Among the clients, only two (who were particularly high in attachment anxiety and who feared abandonment from their therapists) reported dreams that were manifestly about their therapists. Therapists-in-training dreamed more about their clients than their clients dreamed about them. Dreams about clients can be used by therapists to understand themselves, clients, and the dynamics of the therapy relationship.

The reality of the other: dreaming of the analyst.

PubMed

Ferruta, Anna

2009-02-01

The author discusses the obstacles to symbolization encountered when the analyst appears in the first dream of an analysis: the reality of the other is represented through the seeming recognition of the person of the analyst, who is portrayed in undisguised form. The interpretation of this first dream gives rise to reflections on the meaning of the other's reality in analysis: precisely this realistic representation indicates that the function of the other in the construction of the psychic world has been abolished. An analogous phenomenon is observed in the countertransference, as the analyst's mental processes are occluded by an exclusively self-generated interpretation of the patient's psychic world. For the analyst too, the reality of the other proves not to play a significant part in the construction of her interpretation. A 'turning-point' dream after five years bears witness to the power of the transforming function performed by the other throughout the analysis, by way of the representation of characters who stand for the necessary presence of a third party in the construction of a personal psychic reality. The author examines the mutual denial of the other's otherness, as expressed by the vicissitudes of the transference and countertransference between analyst and patient, otherness being experienced as a disturbance of self-sufficient narcissistic functioning. The paper ends with an analysis of the transformations that took place in the analytic relationship.

Reporting dream experience: Why (not) to be skeptical about dream reports

PubMed Central

Windt, Jennifer M.

2013-01-01

Are dreams subjective experiences during sleep? Is it like something to dream, or is it only like something to remember dreams after awakening? Specifically, can dream reports be trusted to reveal what it is like to dream, and should they count as evidence for saying that dreams are conscious experiences at all? The goal of this article is to investigate the relationship between dreaming, dream reporting and subjective experience during sleep. I discuss different variants of philosophical skepticism about dream reporting and argue that they all fail. Consequently, skeptical doubts about the trustworthiness of dream reports are misguided, and for systematic reasons. I suggest an alternative, anti-skeptical account of the trustworthiness of dream reports. On this view, dream reports, when gathered under ideal reporting conditions and according to the principle of temporal proximity, are trustworthy (or transparent) with respect to conscious experience during sleep. The transparency assumption has the status of a methodologically necessary default assumption and is theoretically justified because it provides the best explanation of dream reporting. At the same time, it inherits important insights from the discussed variants of skepticism about dream reporting, suggesting that the careful consideration of these skeptical arguments ultimately leads to a positive account of why and under which conditions dream reports can and should be trusted. In this way, moderate distrust can be fruitfully combined with anti-skepticism about dream reporting. Several perspectives for future dream research and for the comparative study of dreaming and waking experience are suggested. PMID:24223542

At the same time, it inherits important insights from the discussed variants of skepticism about dream reporting, suggesting that the careful consideration of these skeptical arguments ultimately leads to a positive account of why and under which conditions dream reports can and should be trusted. In this way, moderate distrust can be fruitfully combined with anti-skepticism about dream reporting. Several perspectives for future dream research and for the comparative study of dreaming and waking experience are suggested.

DREAMS-SIS: The Solar Irradiance Sensor on-board the ExoMars 2016 lander

The Solar Irradiance Sensor (SIS) was part of the DREAMS (Dust characterization, Risk assessment, and Environment Analyzer on the Martian Surface) payload package on board the ExoMars 2016 Entry and Descent Module (EDM), "Schiaparelli". DREAMS was a meteorological station aimed at the measurement of several atmospheric parameters, as well as the presence of electric fields, during the surface operations of EDM. DREAMS-SIS is a highly miniaturized lightweight sensor designed for small meteorological stations, capable of estimating the aerosol optical depth (AOD) several times per sol, as well as performing a direct measurement of the global (direct plus scattered) irradiance on the Martian surface in the spectral range between 200 and 1100 nm. AOD is estimated from the irradiance measurements at two different spectral bands - Ultraviolet (UV) and near infrared (NIR) - which also enables color index (CI) analysis for the detection of clouds. Despite the failure in the landing of Schiaparelli, DREAMS-SIS is a valuable precursor for new developments being carried-on at present. The concept and design of DREAMS-SIS are here presented and its operating principles, supported by preliminary results from a short validation test, are described. Lessons learnt and future work towards a new generation of Sun irradiance sensors is also outlined.

Ultraviolet (UV) radiation is a major inducer of skin aging and accumulated exposure to UV radiation increases DNA damage in skin cells, including dermal fibroblasts. In the present study, we developed a novel DNA repair regulating material discovery (DREAM) system for the high-throughput screening and identification of putative materials regulating DNA repair in skin cells. First, we established a modified lentivirus expressing the luciferase and hypoxanthine phosphoribosyl transferase (HPRT) genes. Then, human dermal fibroblast WS-1 cells were infected with the modified lentivirus and selected with puromycin to establish cells that stably expressed luciferase and HPRT (DREAM-F cells). The first step in the DREAM protocol was a 96-well-based screening procedure, involving the analysis of cell viability and luciferase activity after pretreatment of DREAM-F cells with reagents of interest and post-treatment with UVB radiation, and vice versa. In the second step, we validated certain effective reagents identified in the first step by analyzing the cell cycle, evaluating cell death, and performing HPRT-DNA sequencing in DREAM-F cells treated with these reagents and UVB. This DREAM system is scalable and forms a time-saving high-throughput screening system for identifying novel anti-photoaging reagents regulating DNA damage in dermal fibroblasts.

The use of dreams in spiritual care.

Stranahan, Susan

2011-01-01

This paper explores the use of dreams in the context of pastoral care. Although many people dream and consider their dreams to hold some significant spiritual meaning, spiritual care providers have been reluctant to incorporate patients' dreams into the therapeutic conversation. Not every dream can be considered insightful, but probing the meaning of some dreams can enhance spiritual care practice. Hill's Cognitive-Experimental Dream Interpretation Model is applied in the current article as a useful framework for exploring dreams, gaining insight about spiritual problems, and developing a therapeutic plan of action. Bulkeley's criteria for dream interpretation were used to furnish safeguards against inappropriate application of dream interpretation to spiritual assessment and interventions.

Frequency of lucid dreaming in a representative German sample.

PubMed

Schredl, Michael; Erlacher, Daniel

2011-02-01

Lucid dreams occur when a person is aware that he is dreaming while he is dreaming. In a representative sample of German adults (N = 919), 51% of the participants reported that they had experienced a lucid dream at least once. Lucid dream recall was significantly higher in women and negatively correlated with age. However, these effects might be explained by the frequency of dream recall, as there was a correlation of .57 between frequency of dream recall and frequency of lucid dreams. Other sociodemographic variables like education, marital status, or monthly income were not related to lucid dream frequency. Given the relatively high prevalence of lucid dreaming reported in the present study, research on lucid dreams might be pursued in the sleep laboratory to expand the knowledge about sleep, dreaming, and consciousness processes in general.

Scientific analysis of the linguistic styles of different authors has generated considerable interest. We present a generic approach to measuring the similarity of two symbolic sequences that requires minimal background knowledge about a given human language. Our analysis is based on word rank order-frequency statistics and phylogenetic tree construction. We demonstrate the applicability of this method to historic authorship questions related to the classic Chinese novel “The Dream of the Red Chamber,” to the plays of William Shakespeare, and to the Federalist papers. This method may also provide a simple approach to other large databases based on their information content.

Investigating on the Methodology Effect When Evaluating Lucid Dream

PubMed Central

Ribeiro, Nicolas; Gounden, Yannick; Quaglino, Véronique

2016-01-01

Lucid dreaming (LD) is a state of consciousness in which the dreamer is aware that he or she is dreaming and can possibly control the content of his or her dream. To investigate the LD prevalence among different samples, researchers have used different types of methodologies. With regard to retrospective self-report questionnaire, two ways of proceeding seem to emerge. In one case, a definition of LD is given to participants (“During LD, one is–while dreaming–aware of the fact that one is dreaming. It is possible to deliberately wake up, to control the dream action, or to observe passively the course of the dream with this awareness”), while in the other instances, participants are presented separate questions targeting specific LD indicators (dream awareness and dream control). In the present study, we measured LD frequency in a sample of French student in order to investigate for possible disparities in LD frequency depending on the type of questionnaire as outlined above. Moreover, we also study links between the prevalence of LD as assessed, respectively, by each questionnaire with various factors such as Vividness of Mental Imagery and Parasomnia. Results revealed no significant difference between LD frequencies across questionnaires. For the questionnaire with definition (DefQuest), 81.05% of participants reported experience of LD once or more. Concerning the questionnaire based on LD indicators (AwarContQuest), 73.38% of participants reported having experienced LD once or more. However, with regard to the correlations analysis, links between LD prevalence and factors such as Vividness of Mental Imagery and Parasomnia, varied across questionnaires. This result is an argument suggesting that researchers should be careful when investigating links between LD and other factors. The type of methodology may influence findings on LD research. Further studies are needed to investigate on the methodology effect in LD research namely on the respective weight of awareness and control. PMID:27625622

The phenomenology of lucid dreaming: an online survey.

PubMed

Stumbrys, Tadas; Erlacher, Daniel; Johnson, Miriam; Schredl, Michael

2014-01-01

In lucid dreams the dreamer is aware that he or she is dreaming. Although such dreams are not that uncommon, many aspects of lucid dream phenomenology are still unclear. An online survey was conducted to gather data about lucid dream origination, duration, active or passive participation in the dream, planned actions for lucid dreams, and other phenomenological aspects. Among the 684 respondents who filled out the questionnaire, there were 571 lucid dreamers (83.5%). According to their reports, lucid dreams most often originate spontaneously in adolescence. The average lucid dream duration is about 14 minutes. Lucid dreamers are likely to be active in their lucid dreams and plan to accomplish different actions (e.g., flying, talking with dream characters, or having sex), yet they are not always able to remember or successfully execute their intentions (most often because of awakening or hindrances in the dream environment). The frequency of lucid dream experience was the strongest predictor of lucid dream phenomenology, but some differences were also observed in relation to age, gender, or whether the person is a natural or self-trained lucid dreamer. The findings are discussed in light of lucid dream research, and suggestions for future studies are provided.

Characteristics and contents of dreams.

2010-01-01

Dreams have been studied from different perspectives: psychoanalysis, academic psychology, and neurosciences. After presenting the definition of dreaming and the methodological tools of dream research, the major findings regarding the phenomenology of dreaming and the factors influencing dream content are briefly reviewed. The so-called continuity hypothesis stating that dreams reflect waking-life experiences is supported by studies investigating the dreams of psychiatric patients and patients with sleep disorders, i.e., their daytime symptoms and problems are reflected in their dreams. Dreams also have an effect on subsequent waking life, e.g., on daytime mood and creativity. The question about the functions of dreaming is still unanswered and open to future research.

2005-04-01

This study examined acculturation as represented in dream narratives of 165 Korean immigrant college students living in the USA. A total of 165 dreams were collected and evaluated using the Lee Acculturation Dream Scale, for which locations of dream contents were coded. 39% of the dreams took place in South Korea, while 38% were in the USA. Also, 16% of the dreams included both locations, whereas 7% had no specific dream location. The dreams contained overlapping dream messages, images, scenes, and interactions in both South Korea and the USA. A two-sample t test on the mean scores of the Lee Acculturation Dream Scale indicated no significant difference between men and women.

A long Saharan dust event over the western Mediterranean: Lidar, Sun photometer observations, and regional dust modeling

A long Saharan dust event affected the western Mediterranean in the period 12-28 June 2002. Dust was present mainly between 1- and 5-km height affecting most parts of the Iberian Peninsula and reaching western/central Europe. Intensive backscatter lidar observations over Barcelona (Spain) and Sun photometer data from two stations (El Arenosillo, Spain, and Avignon, France) are used to evaluate different configurations the Dust Regional Atmospheric Modeling (DREAM) system. DREAM currently operates dust forecasts over the Mediterranean region (http://www.bsc.es/projects/earthscience/DREAM/) considering four particle size bins while only the first two are relevant for long-range transport analysis since their life time is larger than 12 hours. A more detailed bin method is implemented, and two different dust distributions at sources are compared to the operational version. Evaluations are performed at two wavelengths (532 and 1064 nm). The dust horizontal and vertical structure simulated by DREAM shows very good qualitative agreement when compared to SeaWIFS satellite images and lidar height-time displays over Barcelona. When evaluating the modeled aerosol optical depth (AOD) against Sun photometer data, significant improvements are achieved with the use of the new detailed bin method. In general, the model underpredicts the AOD for increasing Ångström exponents because of the influence of anthropogenic pollution in the boundary layer. In fact, the modeled AOD is highly anticorrelated with the observed Ångström exponents. Avignon shows higher influence of small anthropogenic aerosols which explains the better results of the model at the wavelength of 1064 nm over this location. The uncertainties of backscatter lidar inversions (20-30%) are in the same order of magnitude as the differences between the model experiments. Better model results are obtained when comparing to lidar because most of the anthropogenic effect is removed.

Careful analysis of these works will substantiate the assertion that the American Dream, even on the cusp of the new millennium, is just beyond the grasp of this specific subpopulation.

Multiple-try differential evolution adaptive Metropolis for efficient solution of highly parameterized models

NASA Astrophysics Data System (ADS)

Eric, L.; Vrugt, J. A.

2010-12-01

Spatially distributed hydrologic models potentially contain hundreds of parameters that need to be derived by calibration against a historical record of input-output data. The quality of this calibration strongly determines the predictive capability of the model and thus its usefulness for science-based decision making and forecasting. Unfortunately, high-dimensional optimization problems are typically difficult to solve. Here we present our recent developments to the Differential Evolution Adaptive Metropolis (DREAM) algorithm (Vrugt et al., 2009) to warrant efficient solution of high-dimensional parameter estimation problems. The algorithm samples from an archive of past states (Ter Braak and Vrugt, 2008), and uses multiple-try Metropolis sampling (Liu et al., 2000) to decrease the required burn-in time for each individual chain and increase efficiency of posterior sampling. This approach is hereafter referred to as MT-DREAM. We present results for 2 synthetic mathematical case studies, and 2 real-world examples involving from 10 to 240 parameters. Results for those cases show that our multiple-try sampler, MT-DREAM, can consistently find better solutions than other Bayesian MCMC methods. Moreover, MT-DREAM is admirably suited to be implemented and ran on a parallel machine and is therefore a powerful method for posterior inference.

The underlying emotion and the dream relating dream imagery to the dreamer's underlying emotion can help elucidate the nature of dreaming.

PubMed

Hartmann, Ernest

2010-01-01

There is a widespread consensus that emotion is important in dreams, deriving from both biological and psychological studies. However, the emphasis on examining emotions explicitly mentioned in dreams is misplaced. The dream is basically made of imagery. The focus of our group has been on relating the dream imagery to the dreamer's underlying emotion. What is most important is the underlying emotion--the emotion of the dreamer, not the emotion in the dream. This chapter discusses many studies relating the dream-especially the central image of the dream--to the dreamer's underlying emotion. Focusing on the underlying emotion leads to a coherent and testable view of the nature of dreaming. It also helps to clarify some important puzzling features of the literature on dreams, such as why the clinical literature is different in so many ways from the experimental literature, especially the laboratory-based experimental literature. Based on central image intensity and the associated underlying emotion, we can identify a hierarchy of dreams, from the highest-intensity, "big dreams," to the lowest-intensity dreams from laboratory awakenings.

The author discusses bizarre dreams characteristic of epileptics and never occurring in normal subjects which have an important practical implication especially for early detection of epilepsy and the prevention of severe forms of the disease. This group of dreams includes vivid nightmares with vital fear, dreams not infrequently transforming into pro-dream states; persistently repeated stereotyped dreams and dreams with invariably the same unpleasant sensations representing an isolated aura of subsequent epileptic attacks. Diagnostically important may also be dreams with the symptoms of derealization and depersonalization, vague dream images and the deja vu phenomenon.

Dreams of the Rarebit Fiend: food and diet as instigators of bizarre and disturbing dreams

PubMed Central

Nielsen, Tore; Powell, Russell A.

2015-01-01

In the early 1900s, the Dream of the Rarebit Fiend comic strip conveyed how the spicy cheese dish Welsh rarebit leads to bizarre and disturbing dreams. Today, the perception that foods disturb dreaming persists. But apart from case studies, some exploratory surveys, and a few lab studies on how hunger affects dreaming, there is little empirical evidence addressing this topic. The present study examines three aspects of the food/dreaming relationship; it attempts to: (1) assess the prevalence of the perception of food-dependent dreaming and the types of foods most commonly blamed; (2) determine if perceived food-dependent dreaming is associated with dietary, sleep or motivational factors; and (3) explore whether these factors, independent of food/dreaming perceptions, are associated with reports of vivid and disturbing dreams. Three hundred and ninety six students completed questionnaires evaluating sleep, dreams, and dietary habits and motivations. Items queried whether they had noticed if foods produced bizarre or disturbing dreams and if eating late at night influenced their dreams. The perception of food-dependent dreaming had a prevalence of 17.8%; with dairy products being the most frequently blamed food category (39–44%). Those who perceived food-dependent dreaming differed from others by reporting more frequent and disturbing dreams, poorer sleep, higher coffee intake, and lower Intuitive Eating Scale scores. Reports of disturbing dreams were associated with a pathological constellation of measures that includes poorer sleep, binge-eating, and eating for emotional reasons. Reports of vivid dreams were associated with measures indicative of wellness: better sleep, a healthier diet, and longer times between meals (fasting). Results clarify the relationship between food and dreaming and suggest four explanations for the perception of food-dependent dreaming: (1) food specific effects; (2) food-induced distress; (3) folklore influences, and (4) causal misattributions. Research and clinical implications are discussed. PMID:25741294

The dream has always been of interest to psychiatrists. It can assist with the diagnosis and treatment of psychiatric disorders. To find out whether the dream is regarded as meaningful in modern psychiatry and to discover how dreams can be used by psychiatrists in clinical practice. Initially, psychoanalytic monographs on the subject of dreams were read thoroughly. This is followed by a literature search in PubMed and PEPWeb on the basis of the search terms 'dream', 'dreams' and 'dreaming'. results There has been considerable interest in dreams in the psychiatric literature published in the last few decades. Neuroscientific data seem to confirm Freud's wish-fulfilling theory. The dream plays a role in the consolidation of memory. It seems reasonable that psychopathological diagnosis should take the content of dreams into account. Not only is the dream a fascinating subject for research, it is also useful in the diagnosis and treatment of a number of psychiatric disorders.

Consciousness and abilities of dream characters observed during lucid dreaming.

PubMed

Tholey, P

1989-04-01

A description of several phenomenological experiments is given. These were done to investigate of which cognitive accomplishments dream characters are capable in lucid dreams. Nine male experienced lucid dreamers participated as subjects. They were directed to set different tasks to dream characters they met while lucid dreaming. Dream characters were asked to draw or write, to name unknown words, to find rhyme words, to make verses, and to solve arithmetic problems. Part of the dream characters actually agreed to perform the tasks and were successful, although the arithmetic accomplishments were poor. From the phenomenological findings, nothing contradicts the assumption that dream characters have consciousness in a specific sense. Herefrom the conclusion was drawn, that in lucid dream therapy communication with dream characters should be handled as if they were rational beings. Finally, several possibilities of assessing the question, whether dream characters possess consciousness, can be examined with the aid of psychophysiological experiments.

Dreaming and electroencephalographic changes during anesthesia maintained with propofol or desflurane.

Dream recall is reportedly more common after propofol than after volatile anesthesia, but this may be due to delayed emergence or more amnesia after longer-acting volatiles. The electroencephalographic signs of dreaming during anesthesia and the differences between propofol and desflurane also are unknown. The authors therefore compared dream recall after propofol- or desflurane-maintained anesthesia and analyzed electroencephalographic patterns in dreamers and nondreamers and in propofol and desflurane patients for similarities to rapid eye movement and non-rapid eye movement sleep. Three hundred patients presenting for noncardiac surgery were randomized to receive propofol- or desflurane-maintained anesthesia. The raw electroencephalogram was recorded from induction until patients were interviewed about dreaming when they became first oriented postoperatively. Using spectral and ordinal methods, the authors quantified the amount of sleep spindle-like activity and high-frequency power in the electroencephalogram. The incidence of dream recall was similar for propofol (27%) and desflurane (28%) patients. Times to interview were similar (median 20 [range 4-114] vs. 17 [7-86] min; P = 0.1029), but bispectral index values at interview were lower (85 [69-98] vs. 92 [40-98]; P < 0.0001) in propofol than in desflurane patients. During surgery, the raw electroencephalogram of propofol patients showed more and faster spindle activity than in desflurane patients (P < 0.001). The raw electroencephalogram of dreamers showed fewer spindles and more high-frequency power than in nondreamers in the 5 min before interview (P < 0.05). Anesthetic-related dreaming seems to occur just before awakening and is associated with a rapid eye movement-like electroencephalographic pattern.

2016-04-01

The dream activity of patients with primary insomnia (PI) has rarely been studied, especially using in-laboratory dream collection, although dreams could be linked to their state of hyperarousal and their negative waking experiences. The objective of the study was to compare patients with PI and good sleeper controls (GSCs) in terms of dream recall frequency and dream content. Polysomnography was recorded in 12 patients with PI and 12 GSCs (aged between 30 and 45 years) for five consecutive nights. Rapid eye movement (REM) sleep awakenings were enforced on nights 3 and 5 for dream collections. The REM dream collections revealed that the groups were similar in terms of dream recall frequency (p ≤ 0.7). With respect to dream content variables, the dreams of GSCs tended to comprise more positive emotions (p = 0.06), whereas the dreams of patients with PI were characterized by more negative elements than positive ones (p = 0.001). Subjectively, GSCs characterized their dreams as being more pleasant and containing more joy, happiness, and vividness (p ≤ 0.03) than patients with PI. Finally, elevated negative dream content was associated with lower sleep efficiencies in insomnia (p = 0.004). These results suggest that less positive emotions and greater negative content characterize the dreams of patients with PI, which is in line with their waking experiences. One potential explanation could be hyperarousal exacerbating presleep negative mentation, thus contributing to poorer sleep quality. The lack of difference in dream recall frequency is most likely due to the forced awakening "dream collection" procedure. The study of dream activity seems a promising avenue for understanding the 24-h experience of insomnia better and exploring the potential benefits of dream management techniques.

The reinterpretation of dreams: an evolutionary hypothesis of the function of dreaming.

PubMed

Revonsuo, A

2000-12-01

Several theories claim that dreaming is a random by-product of REM sleep physiology and that it does not serve any natural function. Phenomenal dream content, however, is not as disorganized as such views imply. The form and content of dreams is not random but organized and selective: during dreaming, the brain constructs a complex model of the world in which certain types of elements, when compared to waking life, are underrepresented whereas others are over represented. Furthermore, dream content is consistently and powerfully modulated by certain types of waking experiences. On the basis of this evidence, I put forward the hypothesis that the biological function of dreaming is to simulate threatening events, and to rehearse threat perception and threat avoidance. To evaluate this hypothesis, we need to consider the original evolutionary context of dreaming and the possible traces it has left in the dream content of the present human population. In the ancestral environment human life was short and full of threats. Any behavioral advantage in dealing with highly dangerous events would have increased the probability of reproductive success. A dream-production mechanism that tends to select threatening waking events and simulate them over and over again in various combinations would have been valuable for the development and maintenance of threat-avoidance skills. Empirical evidence from normative dream content, children's dreams, recurrent dreams, nightmares, post traumatic dreams, and the dreams of hunter-gatherers indicates that our dream-production mechanisms are in fact specialized in the simulation of threatening events, and thus provides support to the threat simulation hypothesis of the function of dreaming.

Longitudinal with 6 time points from 5 months to 6 years. Subjects' homes. Representative sample of 987 children in the Province of Quebec. None. Longitudinal logistic regression analysis models with primary endpoints of presence or absence of parent-rated bad dreams at 29 months, 41 months, 50 months, 5 years, and 6 years and predictor variables of demographic characteristics, parent ratings of child's sleep characteristics, parental sleep-enabling practices (e.g., cosleeping), and child's psychological characteristics at 5 and 17 months (anxiousness, temperament). Mothers' ratings indicated lower than expected prevalence of frequent bad dreams (1.3% to 3.9%). Demographic correlates of bad dreams were high family income, absence of siblings at 29 months, and a non-immigrant mother. The best predictor at 41 and 50 months was the presence of bad dreams the preceding year, whereas at 5 and 6 years, it was their earlier presence at 29 months. Early protective factors were parental practices favoring emotional nurturance after night awakenings (29 and 41 months); early risk factors were sleep-onset emotional nurturance (29 months), difficult temperament (5 months), and anxiousness (17 months). Bad dreams in preschoolers are less prevalent than thought but, when present, are trait-like in nature and associated with personality characteristics measured as early as 5 months. A stress-diathesis model may best account for the observed pattern of predictive factors.

The Use of Dreams in Psychotherapy

Since the publication of Sigmund Freud's The Interpretation of Dreams, dream interpretation has been a standard technique often used in psychotherapy. However, empirical studies about the frequency of working on dreams in therapy are lacking. The present study elicited, via a self-developed questionnaire, various aspects of work on dreams applied by psychotherapists in private practice. The findings indicate that dreams were often used in therapy, especially in psychoanalysis. In addition, a significant relationship was found between the frequency of the therapists' working on their own dreams and frequency of work on dreams in therapy. Because work on dreams was rated as beneficial for the clients, further studies investigating the effectiveness and the process of working on dreams will be of interest. PMID:10793127

A systematic change in dreams after 9/11/01.

Hartmann, Ernest; Brezler, Tyler

2008-02-01

Previous studies of dreams after trauma and stress have found increases in the power of the central image of the dream. However, it has been difficult to perform properly controlled studies of dreams before and after trauma. The present study is designed to compare dreams before and after 9/11/01 in the same persons. The assumption is that the events of 9/11 produced mild trauma or at the very least emotional arousal in everyone living in the United States. Forty-four persons in the United States who had been recording all their dreams for years each provided 20 consecutive dreams from their records--the last 10 recorded before 9/11 and the first 10 after 9/11. These dreams were assigned random numbers and scored on a blind basis using a number of rating scales with established reliability. Dreams after 9/11 showed a highly significant increase in central image intensity, as well as central image proportion (number of dreams with scorable central images) but no change in dream length, dream-likeness, overall vividness, or content involving airplanes or tall buildings. There were no "exact replay" dreams picturing the actual events of 9/11 seen repeatedly on TV. These results are consistent with the Contemporary Theory of Dreaming, which emphasizes the role of underlying emotion in producing central dream imagery and suggests that the intensity of the central dream imagery is related to the power of the underlying emotion.

Implement Method for Automated Testing of Markov Chain Convergence into INVERSE for ORNL12-RS-108J: Advanced Multi-Dimensional Forward and Inverse Modeling

The DiffeRential Evolution Adaptive Metropolis (DREAM) method is a powerful optimization/uncertainty quantification tool used to solve inverse transport problems in Los Alamos National Laboratory’s INVERSE code system. The DREAM method has been shown to be adept at accurate uncertainty quantification, but it can be very computationally demanding. Previously, the DREAM method in INVERSE performed a user-defined number of particle transport calculations. This placed a burden on the user to guess the number of calculations that would be required to accurately solve any given problem. This report discusses a new approach that has been implemented into INVERSE, the Gelman-Rubin convergence metric.more » This metric automatically detects when an appropriate number of transport calculations have been completed and the uncertainty in the inverse problem has been accurately calculated. In a test problem with a spherical geometry, this method was found to decrease the number of transport calculations (and thus time required) to solve a problem by an average of over 90%. In a cylindrical test geometry, a 75% decrease was obtained.« less

When dreaming is believing: the (motivated) interpretation of dreams.

PubMed

Morewedge, Carey K; Norton, Michael I

2009-02-01

This research investigated laypeople's interpretation of their dreams. Participants from both Eastern and Western cultures believed that dreams contain hidden truths (Study 1) and considered dreams to provide more meaningful information about the world than similar waking thoughts (Studies 2 and 3). The meaningfulness attributed to specific dreams, however, was moderated by the extent to which the content of those dreams accorded with participants' preexisting beliefs--from the theories they endorsed to attitudes toward acquaintances, relationships with friends, and faith in God (Studies 3-6). Finally, dream content influenced judgment: Participants reported greater affection for a friend after considering a dream in which a friend protected rather than betrayed them (Study 5) and were equally reluctant to fly after dreaming or learning of a plane crash (Studies 2 and 3). Together, these results suggest that people engage in motivated interpretation of their dreams and that these interpretations impact their everyday lives.

The death of a person is a stressful event. Such stress affects the physical and psychological well-being of the bereaved. As an associated mental disorder, major depressive disorder (MDD) is common. Some dream of the deceased, and these dreams are called bereavement dreams. Some MDD patients also experience dreams. These two types of dreams are sometimes difficult to differentiate. The dream of the bereaved might be only a bereavement-related dream, yet it might be a symptom of MDD. Herein, we report one patient who had distressing dreams after the death of her mother. A 63-year-old woman was referred for psychiatric consultation because of generalized fatigue and insomnia. Questioning her about recent events, she said that her mother had died of colonic carcinoma 5 months previously. Two months after the death, she suddenly started dreaming of her mother, getting angry with her almost every night. Generalized fatigue, insomnia, and distressing dreams appeared simultaneously. The dream caused much distress, making her afraid to fall asleep. Her psychiatric features fulfilled the DSM-IV-TR criteria for MDD, single episode. The death of her mother was considered to be one of the causes of MDD. She was administered 25 mg/day of sertraline hydrochloride. After that, her symptoms gradually disappeared, and the frequency of distressing dreams was reduced. Five months later, physical and psychiatric symptoms of MDD were completely resolved. Subsequently, she has not suffered from any distressing dreams of her mother. This case indicates that dreams experienced after the death of a loved one should not be regarded simply as bereavement dreams. Some of the dreams may be symptoms of MDD. If the dreams are the symptoms of MDD, antidepressant treatment as well as psychotherapy may be useful. Therefore, we should avoid regarding symptoms of MDD as reactions to bereavement.

Affect integration in dreams and dreaming.

PubMed

Grenell, Gary

2008-03-01

The processes by which dreaming aids in the ongoing integration of affects into the mind are approached here from complementary psychoanalytic and nonpsychoanalytic perspectives. One relevant notion is that the dream provides a psychological space wherein overwhelming, contradictory, or highly complex affects that under waking conditions are subject to dissociation, splitting, or disavowal may be brought together for observation by the dreaming ego. This process serves the need for psychological balance and equilibrium. A brief discussion of how the mind processes information during dreaming is followed by a consideration of four component aspects of the integrative process: the nature and use of the dream-space, the oscillating "me / not me" quality of the dream, the apparent reality of the dream, and the use of nonpathological projective identification in dreaming. Three clinical illustrations are offered and discussed.

The Curious Connection Between Insects and Dreams.

A majority of humans spend their waking hours surrounded by insects, so it should be no surprise that insects also appear in humans' dreams as we sleep. Dreaming about insects has a peculiar history, marked by our desire to explain a dream's significance and by the tactic of evoking emotions by injecting insects in dream-related works of art, film, music, and literature. I surveyed a scattered literature for examples of insects in dreams, first from the practices of dream interpretation, psychiatry, and scientific study, then from fictional writings and popular culture, and finally in the etymology of entomology by highlighting insects with dream-inspired Latinate names. A wealth of insects in dreams, as documented clinically and culturally, attests to the perceived relevance of dreams and to the ubiquity of insects in our lives.

The question that we deal with in this commentary is the need to clarify the synergistic role of different non-rapid eye movement (NREM) sleep stages (stages 2 and 3-4) with REM and while awake in elaborative encoding of episodic memory. If the assumption is that there is isomorphism between neuronal and cognitive networks, then more detailed analysis of NREM sleep and dreams is absolutely necessary.

DREAM plays an important role in platelet activation and thrombogenesis

PubMed Central

Kim, Kyungho; Tseng, Alan; Barazia, Andrew; Italiano, Joseph E.

2017-01-01

Downstream regulatory element antagonist modulator (DREAM), a transcriptional repressor, is known to modulate pain responses. However, it is unknown whether DREAM is expressed in anucleate platelets and plays a role in thrombogenesis. By using intravital microscopy with DREAM-null mice and their bone marrow chimeras, we demonstrated that both hematopoietic and nonhematopoietic cell DREAMs are required for platelet thrombus formation following laser-induced arteriolar injury. In a FeCl3-induced thrombosis model, we found that compared with wild-type (WT) control and nonhematopoietic DREAM knockout (KO) mice, DREAM KO control and hematopoietic DREAM KO mice showed a significant delay in time to occlusion. Tail bleeding time was prolonged in DREAM KO control mice, but not in WT or DREAM bone marrow chimeric mice. In vivo adoptive transfer experiments further indicated the importance of platelet DREAM in thrombogenesis. We found that DREAM deletion does not alter the ultrastructural features of platelets but significantly impairs platelet aggregation and adenosine triphosphate secretion induced by numerous agonists (collagen-related peptide, adenosine 5′-diphosphate, A23187, thrombin, or U46619). Biochemical studies revealed that platelet DREAM positively regulates phosphoinositide 3-kinase (PI3K) activity during platelet activation. Using DREAM-null platelets and PI3K isoform-specific inhibitors, we observed that platelet DREAM is important for α-granule secretion, Ca2+ mobilization, and aggregation through PI3K class Iβ (PI3K-Iβ). Genetic and pharmacological studies in human megakaryoblastic MEG-01 cells showed that DREAM is important for A23187-induced Ca2+ mobilization and its regulatory function requires Ca2+ binding and PI3K-Iβ activation. These results suggest that platelet DREAM regulates PI3K-Iβ activity and plays an important role during thrombus formation. PMID:27903531

Assess incidence and clarify whether diagnostic correlates exist for sleep laboratory patients reporting a lack of dream recall. To awaken, during polysomnographically defined sleep including rapid eye movement (REM) sleep, individuals reporting never having experienced a dream, and determine whether they report dreaming. Study # 1 - Incidence and polysomnographic correlates of sleep lab patients responding on questionnaire that they had never experienced dreaming. Study # 2 - Phone interviews with those individuals reporting non-dreaming on questionnaire to reassess incidence. Study # 3 - After reassessment, individuals (non-dreamers - # 16) are awakened during polysomnographic defined sleep (including REM sleep) and queried about dream recall. This group is compared statistically to a group (rare-dreamers - # 12) that reported dreaming as an extremely rare occurrence (mean dream recall latency - 13.5 years). Study # 1: Incidence of questionnaire reported non-dreaming in this sleep laboratory population is 6.5% (N=534) and is associated with the diagnosis of obstructive sleep apnea (specificity 95.6% for respiratory disturbance index >15). Study # 2 - Individuals who report after interview to have never experienced dreaming are more unusual (0.38% of this sleep laboratory population). Study # 3 - None of the non-dreamers (# 16) reported dream recall after waking in the sleep laboratory (36 awakenings in total for this group). This group does not differ, based on polysomnographic, clinical, or demographic variables, from the rare-dreaming group that occasionally reported dreams when awakened (3/12 patients, 3/32 awakenings) - a finding consistent with the reports of previous studies. The experience of dreaming may not be as ubiquitous as generally accepted. The group of non-dreamers evaluated in this study reports never having recalled a dream and reports no dreams when awakened during polysomnographicly defined sleep. These individuals might not experience dreaming.

Dreams and acting out.

PubMed

Grinberg, L

1987-01-01

Dreams can be used as containers that free patients from increased tension. This may be the principal function of certain types of dreams, called "evacuative dreams." They are dreams used for getting rid of unbearable affects and unconscious fantasies, or as a safety valve for partial discharge of instinctual drives. These dreams are observed primarily in borderline and psychotic patients, but can also be seen in the regressive states of neurotic patients during weekends and other periods of separation. Such dreams have to be differentiated from "elaborative dreams," which have a working-through function and stand in an inverse relationship to acting out: the greater the production of elaborative dreams, the less the tendency to act out, and vice versa.

Are they autonomous productions of psyché or phantasia, or rather messages sent by demons or God, according to dreams' bad or good intimate nature? Is there a relation between time of the night and nature of the dreams? Moreover, is there a relation between seasons and dreams? Does a specific relationship between food, regimen and dreams exist? Which is the soul's faculty able to generate dreams? Is phantasia moved by some other deep and mysterious principle? Which are the connections linking human physiology and dreams?

Intraoperative dreams reported after general anaesthesia are not early interpretations of delayed awareness.

Dreams are more frequently reported than awareness after surgery. We define awareness as explicit recall of real intraoperative events during anaesthesia. The importance of intraoperative dreaming is poorly understood. This study was performed to evaluate whether intraoperative dreams can be associated with, or precede, awareness. We also studied whether dreams can be related to case-specific parameters. A cohort of 6991 prospectively included patients given inhalational anaesthesia were interviewed for dreams and awareness at three occasions; before they left the post-anaesthesia care unit, days 1-3 and days 7-14 after the operation. Uni- and multivariate statistical relations between dreams, awareness and case-specific parameters were assessed. Two hundred and thirty-two of 6991 patients (3.3%) reported a dream. Four of those also reported awareness and remembered real events that were distinguishable from their dream. Awareness was 19 times more common among patients who after surgery reported a dream [1.7% vs. 0.09%; odds ratio (OR) 18.7; P=0.000007], but memories of dreams did not precede memories of awareness in any of the 232 patients reporting a dream. Unpleasant dreams were significantly more common when thiopentone was used compared with propofol (OR 2.22; P=0.005). Neutral or pleasant dreams were related to lower body mass index, female gender and shorter duration of anaesthesia. We found a statistically significant association between dreams reported after general anaesthesia and awareness, although intraoperative dreams were not an early interpretation of delayed awareness in any case. A typical dreamer in this study is a lean female having a short procedure.

Longitudinal Study of Bad Dreams in Preschool-Aged Children: Prevalence, Demographic Correlates, Risk and Protective Factors

Study objectives: To (1) clarify the epidemiology of bad dreams in children and investigate risk and protective factors related to (2) the child's sleep, (3) parental sleep-enabling practices, and (4) the child's temperament. Design: Longitudinal with 6 time points from 5 months to 6 years. Setting: Subjects' homes. Participants: Representative sample of 987 children in the Province of Quebec. Interventions: None. Measurements and Results: Longitudinal logistic regression analysis models with primary endpoints of presence or absence of parent-rated bad dreams at 29 months, 41 months, 50 months, 5 years, and 6 years and predictor variables of demographic characteristics, parent ratings of child's sleep characteristics, parental sleep-enabling practices (e.g., cosleeping), and child's psychological characteristics at 5 and 17 months (anxiousness, temperament). Mothers' ratings indicated lower than expected prevalence of frequent bad dreams (1.3% to 3.9%). Demographic correlates of bad dreams were high family income, absence of siblings at 29 months, and a non-immigrant mother. The best predictor at 41 and 50 months was the presence of bad dreams the preceding year, whereas at 5 and 6 years, it was their earlier presence at 29 months. Early protective factors were parental practices favoring emotional nurturance after night awakenings (29 and 41 months); early risk factors were sleep-onset emotional nurturance (29 months), difficult temperament (5 months), and anxiousness (17 months). Conclusions: Bad dreams in preschoolers are less prevalent than thought but, when present, are trait-like in nature and associated with personality characteristics measured as early as 5 months. A stress-diathesis model may best account for the observed pattern of predictive factors. Citation: Simard V; Nielsen TA; Tremblay RE; Boivin M; Montplaisir JY.

Psychosis and the Control of Lucid Dreaming.

2016-01-01

Dreaming and psychosis share important features, such as intrinsic sense perceptions independent of external stimulation, and a general lack of criticism that is associated with reduced frontal cerebral activity. Awareness of dreaming while a dream is happening defines lucid dreaming (LD), a state in which the prefrontal cortex is more active than during regular dreaming. For this reason, LD has been proposed to be potentially therapeutic for psychotic patients. According to this view, psychotic patients would be expected to report LD less frequently, and with lower control ability, than healthy subjects. Furthermore, psychotic patients able to experience LD should present milder psychiatric symptoms, in comparison with psychotic patients unable to experience LD. To test these hypotheses, we investigated LD features (occurrence, control abilities, frequency, and affective valence) and psychiatric symptoms (measure by PANSS, BPRS, and automated speech analysis) in 45 subjects with psychotic symptoms [25 with Schizophrenia (S) and 20 with Bipolar Disorder (B) diagnosis] versus 28 non-psychotic control (C) subjects. Psychotic lucid dreamers reported control of their dreams more frequently (67% of S and 73% of B) than non-psychotic lucid dreamers (only 23% of C; S > C with p = 0.0283, B > C with p = 0.0150). Importantly, there was no clinical advantage for lucid dreamers among psychotic patients, even for the diagnostic question specifically related to lack of judgment and insight. Despite some limitations (e.g., transversal design, large variation of medications), these preliminary results support the notion that LD is associated with psychosis, but falsify the hypotheses that we set out to test. A possible explanation is that psychosis enhances the experience of internal reality in detriment of external reality, and therefore lucid dreamers with psychotic symptoms would be more able to control their internal reality than non-psychotic lucid dreamers. Training dream lucidity is likely to produce safe psychological strengthening in a non-psychotic population, but in a psychotic population LD practice may further empower deliria and hallucinations, giving internal reality the appearance of external reality.

The dream-lag effect refers to there being, after the frequent incorporation of memory elements from the previous day into dreams (the day-residue), a lower incorporation of memory elements from 2 to 4 days before the dream, but then an increased incorporation of memory elements from 5 to 7 days before the dream. Participants (n=8, all female) kept a daily diary and a dream diary for 14 days and then rated the level of matching between every dream report and every daily diary record. Baseline matching was assessed by comparing all dream reports to all diary records for days that occurred after the dream. A significant dream-lag effect for the 5-7 day period, compared to baseline and compared to the 2-4 day period, was found. This may indicate a memory processing function for sleep, which the dream content may reflect. Participants' and three independent judges' mean ratings also confirmed a significant day-residue effect. Copyright © 2010 Elsevier Inc. All rights reserved.

Last night I had the strangest dream: Varieties of rational thought processes in dream reports.

PubMed

Wolman, Richard N; Kozmová, Miloslava

2007-12-01

From the neurophysiological perspective, thinking in dreaming and the quality of dream thought have been considered hallucinatory, bizarre, illogical, improbable, or even impossible. This empirical phenomenological research concentrates on testing whether dream thought can be defined as rational in the sense of an intervening mental process between sensory perception and the creation of meaning, leading to a conclusion or to taking action. From 10 individual dream journals of male participants aged 22-59 years and female participants aged 25-49 years, we delimited four dreams per journal and randomly selected five thought units from each dream for scoring. The units provided a base for testing a hypothesis that the thought processes of dream construction are rational. The results support the hypothesis and demonstrate that eight fundamental rational thought processes can be applied to the dreaming process.

Descartes' dreams.

PubMed

Withers, Robert

2008-11-01

René Descartes is often regarded as the 'father of modern philosophy'. He was a key figure in instigating the scientific revolution that has been so influential in shaping our modern world. He has been revered and reviled in almost equal measure for this role; on the one hand seen as liberating science from religion, on the other as splitting soul from body and man from nature. He dates the founding of his philosophical methods to the night of 10(th) November 1619 and in particular to three powerful dreams he had that night. This article utilizes Descartes' own interpretations of the dreams, supported by biographical material, as well as contemporary neuroscientific and psychoanalytic theory, to reach a new understanding of them. It is argued that the dreams can be understood as depicting Descartes' personal journey from a state of mind-body dissociation to one of mind-body deintegration. This personal journey may have implications for a parallel journey from Renaissance to modern culture and from modernity to post-modern culture.

Daydreams and nap dreams: Content comparisons.

2015-11-01

Differences between nighttime REM and NREM dreams are well-established but only rarely are daytime REM and NREM nap dreams compared with each other or with daydreams. Fifty-one participants took daytime naps (with REM or NREM awakenings) and provided both waking daydream and nap dream reports. They also provided ratings of their bizarreness, sensory experience, and emotion intensity. Recall rates for REM (96%) and NREM (89%) naps were elevated compared to typical recall rates for nighttime dreams (80% and 43% respectively), suggesting an enhanced circadian influence. All attribute ratings were higher for REM than for NREM dreams, replicating findings for nighttime dreams. Compared with daydreams, NREM dreams had lower ratings for emotional intensity and sensory experience while REM dreams had higher ratings for bizarreness and sensory experience. Results support using daytime naps in dream research and suggest that there occurs selective enhancement and inhibition of specific dream attributes by REM, NREM and waking state mechanisms.

Sikka, Pilleriin; Valli, Katja; Virta, Tiina; Revonsuo, Antti

2014-04-01

We investigated whether inconsistencies in previous studies regarding emotional experiences in dreams derive from whether dream emotions are self-rated or externally evaluated. Seventeen subjects were monitored with polysomnography in the sleep laboratory and awakened from every rapid eye movement (REM) sleep stage 5 min after the onset of the stage. Upon awakening, participants gave an oral dream report and rated their dream emotions using the modified Differential Emotions Scale, whereas external judges rated the participants' emotions expressed in the dream reports, using the same scale. The two approaches produced diverging results. Self-ratings, as compared to external ratings, resulted in greater estimates of (a) emotional dreams; (b) positively valenced dreams; (c) positive and negative emotions per dream; and (d) various discrete emotions represented in dreams. The results suggest that this is mostly due to the underrepresentation of positive emotions in dream reports. Possible reasons for this discrepancy are discussed. Copyright © 2014 Elsevier Inc.

In 13 patients dreams increased in frequency and intensity, and in five the dreams assumed frightening proportions. There was a significant straight-line relation between response and the size of the dose. When placebo tablets were given to four patients their dreams disappeared or assumed their pretreatment normal pattern. Absence of vitamin C from the diet did not significantly affect the dream pattern. That fenfluramine has dose-related cerebral effects should be remembered in patients with a history of mental illness.

1987-11-01

Dream reports were collected over a 10-year period as part of an ethnographic study of mentally retarded employees in a sheltered workshop. Deceased loved ones, usually parents or other family members, figured prominently as characters in many of these dreams. Dreams about the dead were often recurring and elicited salient emotional reactions from the dreamers. The various forms that these dreams take and their characteristic thematic content were described for 154 dreams by 60 dreamers. Some of the percepts and feelings that reflect the dreamers' understanding of their dreams were also noted. Findings reveal that the dream life of retarded adults is much more rich and diverse than previous studies suggest. Clinical implications and the occurrence of similar dreams among nonretarded persons were discussed.

Reflections on the self state dream.

PubMed

Slap, J W; Trunnell, E E

1987-04-01

Self psychologists contend that patients with narcissistic personality disorders have dreams which cannot be understood in terms of current psychoanalytic dream theory and that these dreams, called self state dreams, have a different origin and structure. The manifest content of these dreams is said to reveal the reactions of healthy sectors of the psyche to disturbing changes in the condition of the self. Self psychologists are said to be able to understand these dreams directly, without the patients' associations, as portrayals of the dreamers' dread of threats to the integrity of the self. The authors raise questions about these contentions. They conclude that the self state dream will remain a dubious concept until a more extensive psychology of dreaming is provided by self psychologists.

How dreams are told: secondary revision--the critic, the editor, and the plagiarist.

PubMed

Stein, M H

1989-01-01

Secondary revision is a highly provocative concept arising out of Freud's attempts to explain the construction of dreams, but it remains relatively ill-defined. It includes three related, yet by no means identical aspects of the process by which the dream acquires its more or less final form during the experiencing, the remembering, and the telling. It represents one of the most interesting hypotheses dealing with the fluid world between sleeping and waking, a field which still presents us with a host of unanswered questions. Secondary revision not only reflects the higher levels of the dreamer's mental functioning superimposed on his biological substructure, but it also operates as a sensitive indicator of the cultural factors which have helped mold his personality. These factors include both the subculture of the analytic situation and the impact of society in the larger sense. I make reference to individual dreamers in analysis and to the world of dreams recorded in the past from our own and other cultures.

Another look at dreaming: disentangling Freud's primary and secondary process theories.

PubMed

Robbins, Michael

2004-01-01

The Interpretation of Dreams contains Freud's first and most complete articulation of the primary and secondary mental processes that serve as a framework for the workings of mind, conscious and unconscious. While it is generally believed that Freud proposed a single theory of dreaming, based on the primary process, a number of ambiguities, inconsistencies, and contradictions reflect an incomplete differentiation of the parts played by the two mental processes in dreaming. It is proposed that two radically different hypotheses about dreaming are embedded in Freud's work. The one implicit in classical dream interpretation is based on the assumption that dreams, like waking language, are representational, and are made up of symbols connected to latent unconscious thoughts. Whereas the symbols that constitute waking language are largely verbal and only partly unconscious, those that constitute dreams are presumably more thoroughly disguised and represented as arcane hallucinated hieroglyphs. From this perspective, both the language of the dream and that of waking life are secondary process manifestations. Interpretation of the dream using the secondary process model involves the assumption of a linear two-way "road" connecting manifest and latent aspects, which in one direction involves the work of dream construction and in the other permits the associative process of decoding and interpretation. Freud's more revolutionary hypothesis, whose implications he did not fully elaborate, is that dreams are the expression of a primary mental process that differs qualitatively from waking thought and hence are incomprehensible through a secondary process model. This seems more adequately to account for what is now known about dreaming, and is more consistent with the way dream interpretation is ordinarily conducted in clinical practice. Recognition that dreams are qualitatively distinctive expressions of mind may help to restore dreaming to its privileged position as a unique source of mental status information.

Incorporation of recent waking-life experiences in dreams correlates with frontal theta activity in REM sleep.

Rapid Eye Movement (REM) sleep and its main oscillatory feature, frontal theta, have been related to the processing of recent emotional memories. As memories constitute much of the source material for our dreams, we explored the link between REM frontal theta and the memory sources of dreaming, so as to elucidate the brain activities behind the formation of dream content. Twenty participants were woken for dream reports in REM and Slow Wave Sleep (SWS) while monitored using electroencephalography. Eighteen participants reported at least one REM dream and 14 at least one SWS dream, and they, and independent judges, subsequently compared their dream reports with log records of their previous daily experiences. The number of references to recent waking-life experiences in REM dreams was positively correlated with frontal theta activity in the REM sleep period. No such correlation was observed for older memories, nor for SWS dreams. The emotional intensity of recent waking-life experiences incorporated into dreams was higher than the emotional intensity of experiences that were not incorporated. These results suggest that the formation of wakefulness-related dream content is associated with REM theta activity, and accords with theories that dreaming reflects emotional memory processing taking place in REM sleep.

Variety and intensity of emotions in nightmares and bad dreams.

PubMed

Zadra, Antonio; Pilon, Mathieu; Donderi, Don C

2006-04-01

Nightmares are usually defined as frightening dreams that awaken the sleeper. This study uses the waking criterion to distinguish between nightmares and bad dreams and investigated the variety and intensity of emotions reported in each form of disturbing dream. Ninety participants recorded their dreams for 4 consecutive weeks and, for each dream recalled, noted the emotions present and their intensities on a 9-point scale. Thirty-six participants reported at least one nightmare and one bad dream over the 4 weeks covered by the log, while 29 reported having had at least one bad dream but no nightmares. Nightmares were rated as being significantly (p < 0.001) more intense than bad dreams. Thirty percent of nightmares and 51% of bad dreams contained primary emotions other than fear. The findings support the claim that awakening can serve as an indirect measure of nightmare intensity and raise important implications for the operational definition of nightmares.

Representation of the Self in REM and NREM Dreams

PubMed Central

McNamara, Patrick; McLaren, Deirdre; Durso, Kate

2008-01-01

The authors hypothesized that representations of the Self (or the dreamer) in dreams would change systematically, from a prereflective form of Self to more complex forms, as a function of both age and sleep state (REM vs. non-REM). These hypotheses were partially confirmed. While the authors found that all the self-concept-related dream content indexes derived from the Hall/Van de Castle dream content scoring system did not differ significantly between the dreams of children and adults, adult Selves were more likely to engage in “successful” social interactions. The Self never acted as aggressor in NREM dream states and was almost always the befriender in friendly interactions in NREM dreams. Conversely, the REM-related dream Self preferred aggressive encounters. Our results suggests that while prereflective forms of Self are the norm in children’s dreams, two highly complex forms of Self emerge in REM and NREM dreams. PMID:19169371

DREAMING THE ANALYTIC SESSION: A CLINICAL ESSAY.

PubMed

Ogden, Thomas H

2017-01-01

This is a clinical paper in which the author describes analytic work in which he dreams the analytic session with three of his patients. He begins with a brief discussion of aspects of analytic theory that make up a good deal of the context for his clinical work. Central among these concepts are (1) the idea that the role of the analyst is to help the patient dream his previously "undreamt" and "interrupted" dreams; and (2) dreaming the analytic session involves engaging in the experience of dreaming the session with the patient and, at the same time, unconsciously (and at times consciously) understanding the dream. The author offers no "technique" for dreaming the analytic session. Each analyst must find his or her own way of dreaming each session with each patient. Dreaming the session is not something one works at; rather, one tries not to get in its way. © 2017 The Psychoanalytic Quarterly, Inc.

Beware of being captured by an analogy: dreams are like many things.

Erdelyi, Matthew Hugh

2013-12-01

Classic traditions have linked dreams to memory (e.g., "dreaming is another kind of remembering" [Freud 1918/1955]) and modern notions like implicit memory subsume dreaming by definition. Llewellyn develops the more specific thesis that rapid eye movement (REM) dreams, because of their similarities to mnemonic techniques, have the function of elaboratively encoding episodic memories. This proposal is premature, requiring exigent testing. Other analogs of dreams, for example, jokes, do not invoke function but do contribute to dream science.

On dreaming one's patient: reflections on an aspect of countertransference dreams.

PubMed

Brown, Lawrence J

2007-07-01

This paper explores the phenomenon of the countertransference dream. Until very recently, such dreams have tended to be seen as reflecting either unanalyzed difficulties in the analyst or unexamined conflicts in the analytic relationship. While the analyst's dream of his/her patient may represent such problems, the author argues that such dreams may also indicate the ways in which the analyst comes to know the patient on a deep, unconscious level by processing the patient's communicative projective identifications. Two extended clinical examples of the author's countertransference dreams are offered. The author also discusses the use of countertransference dreams in psychoanalytic supervision.

Characteristics of the memory sources of dreams: A new version of the content-matching paradigm to take mundane and remote memories into account.

PubMed

Vallat, Raphael; Chatard, Benoit; Blagrove, Mark; Ruby, Perrine

2017-01-01

Several studies have demonstrated that dream content is related to the waking life of the dreamer. However, the characteristics of the memory sources incorporated into dreams are still unclear. We designed a new protocol to investigate remote memories and memories of trivial experiences, both relatively unexplored in dream content until now. Upon awakening, for 7 days, participants identified the waking life elements (WLEs) related to their dream content and characterized them and their dream content on several scales to assess notably emotional valence. Thanks to this procedure, they could report WLEs from the whole lifespan, and mundane ones before they had been forgotten. Participants (N = 40, 14 males, age = 25.2 ± 7.6) reported 6.2 ± 2.0 dreams on average. For each participant, 83.4% ± 17.8 of the dream reports were related to one or more WLEs. Among all the WLEs incorporated into dreams dated by the participants (79.3 ± 19%), 40.2 ± 30% happened the day before the dream, 26.1 ± 26% the month before (the day before excluded), 15.8 ± 21% the year before the dream (the month before excluded), and 17.9 ± 24% happened more than one year before the dream. As could be expected from previous studies, the majority of the WLEs incorporated into dreams were scored as important by the dreamers. However, this was not true for incorporated WLEs dating from the day before the dream. In agreement with Freud's observations, the majority of the day residues were scored as mundane. Finally, for both positive and negative WLEs incorporated into dreams, the dreamt version of the WLE was rated as emotionally less intense than the original WLE. This result, showing that dreams tend to attenuate the emotional tone of waking-life memories towards a more neutral one, argues in favor of the emotional regulation hypothesis of dreaming.

This art of psychoanalysis. Dreaming undreamt dreams and interrupted cries.

PubMed

Ogden, Thomas H

2004-08-01

It is the art of psychoanalysis in the making, a process inventing itself as it goes, that is the subject of this paper. The author articulates succinctly how he conceives of psychoanalysis, and offers a detailed clinical illustration. He suggests that each analysand unconsciously (and ambivalently) is seeking help in dreaming his 'night terrors' (his undreamt and undreamable dreams) and his 'nightmares' (his dreams that are interrupted when the pain of the emotional experience being dreamt exceeds his capacity for dreaming). Undreamable dreams are understood as manifestations of psychotic and psychically foreclosed aspects of the personality; interrupted dreams are viewed as reflections of neurotic and other non-psychotic parts of the personality. The analyst's task is to generate conditions that may allow the analysand--with the analyst's participation--to dream the patient's previously undreamable and interrupted dreams. A significant part of the analyst's participation in the patient's dreaming takes the form of the analyst's reverie experience. In the course of this conjoint work of dreaming in the analytic setting, the analyst may get to know the analysand sufficiently well for the analyst to be able to say something that is true to what is occurring at an unconscious level in the analytic relationship. The analyst's use of language contributes significantly to the possibility that the patient will be able to make use of what the analyst has said for purposes of dreaming his own experience, thereby dreaming himself more fully into existence.

The informational value of dreams and associations.

PubMed

Olsson, G

1996-03-01

The manifest dream has usually been the object of study by researchers, while psychotherapists mainly have paid attention to the latent content of the dream, reached through free associations. The question is which aspects of the dream, manifest content or associations, yield information about the dreamer's psychic life. In the present study it is suggested that the manifest dream to a large extent maintains thematic continuity with the dreamer's associations. However, with regard to emotions, there is no clear overlap between the information contained in the manifest dream and in its associations. The associations make the dream into the dreamer's own personal dream. Associating to a dream changes strangers into known people in the life of the dreamer. The dreamer comes to recognize aspects of himself or herself in these people. In associations, the dreamers portray themselves as more responsible of emotions, while they in dreams rather ascribe emotions to others, and they themselves become objects of these emotions. The author argues for the value of both the manifest dream in its own right and the enhanced experiental closeness afforded by the dreamer's associations.

Consciousness in dreams.

PubMed

Kahn, David; Gover, Tzivia

2010-01-01

This chapter argues that dreaming is an important state of consciousness and that it has many features that complement consciousness in the wake state. The chapter discusses consciousness in dreams and how it comes about. It discusses the changes that occur in the neuromodulatory environment and in the neuronal connectivity of the brain as we fall asleep and begin our night journeys. Dreams evolve from internal sources though the dream may look different than any one of these since something entirely new may emerge through self-organizing processes. The chapter also explores characteristics of dreaming consciousness such as acceptance of implausibility and how that might lead to creative insight. Examples of studies, which have shown creativity in dream sleep, are provided to illustrate important characteristics of dreaming consciousness. The chapter also discusses the dream body and how it relates to our consciousness while dreaming. Differences and similarities between wake, lucid, non-lucid and day dreaming are explored and the chapter concludes with a discussion on what we can learn from each of these expressions of consciousness.

Dreaming: a gateway to the unconscious?

Paulson, Steve; Barrett, Deirdre; Bulkeley, Kelly; Naiman, Rubin

2017-10-01

Where do our dreams originate from, and what do they tell us? Is there a universal set of symbols that are common to all dreams, regardless of a person's ethnicity or culture? What does dreaming reveal about the unconscious? Why do some dreams remain etched in our memories, whereas others are almost instantly forgotten? Some scientists have adopted the position that dreams are little more than noise in the brain, without any substantive purpose or function. Yet, such a stance seemingly runs counter to the experience of many people who reflect upon and even analyze their dreams, often in search of clues to their daily lives or insights into their deeper selves. Similarly, in virtually all wisdom traditions, dreams are invoked as an important source of revelation or prophecy. Steve Paulson, executive producer and host of To the Best of Our Knowledge, moderated a discussion that included psychologist Deirdre Barrett, dream researcher Kelly Bulkeley, and psychologist and sleep/dream medicine specialist Rubin Naiman; they examined dreams from a variety of perspectives to answer these questions. © 2017 New York Academy of Sciences.

The riddle of Siegfried: exploring methods and psychological perspectives in analytical psychology.

Jung's dream of the killing of Siegfried poses a riddle: why did the unconscious choose precisely Siegfried as the hero to be murdered? Jung himself declares that he does not know. This paper attempts to decipher this riddle using three distinct methodological approaches accepted by Jung, two of them in fact grounded in his theories of dream interpretation. Besides presenting some possible answers to the riddle of Siegfried, this interpretative reflection brings to light the discrepancy of the psychological perspectives created by the heterogeneity of methods within analytical psychology. © 2016, The Society of Analytical Psychology.

The impact of dreams of the deceased on bereavement: a survey of hospice caregivers.

2014-03-01

Many recently bereaved persons experience vivid and deeply meaningful dreams featuring the presence of the deceased that may reflect and impact the process of mourning. The present study surveyed 278 bereaved persons regarding their own perspective of the relationship between dreams and the mourning process. Fifty eight percent of respondents reported dreams of their deceased loved ones, with varying levels of frequency. Most participants reported that their dreams were either pleasant or both pleasant and disturbing, and few reported purely disturbing dreams. Prevalent dream themes included pleasant past memories or experiences, the deceased free of illness, memories of the deceased's illness or time of death, the deceased in the afterlife appearing comfortable and at peace, and the deceased communicating a message. These themes overlap significantly with previous models of bereavement dream content. Sixty percent of participants felt that their dreams impacted their bereavement process. Specific effects of the dreams on bereavement processes included increased acceptance of the loved one's death, comfort, spirituality, sadness, and quality of life, among others. These results support the theory that dreams of the deceased are highly prevalent among and often deeply meaningful for the bereaved. While many counselors are uncomfortable working with dreams in psychotherapy, the present study demonstrates their therapeutic relevance to the bereaved population and emphasizes the importance for grief counselors to increase their awareness, knowledge, and skills with regards to working with dreams.

The dream-lag effect: Selective processing of personally significant events during Rapid Eye Movement sleep, but not during Slow Wave Sleep.

Incorporation of details from waking life events into Rapid Eye Movement (REM) sleep dreams has been found to be highest on the night after, and then 5-7 nights after events (termed, respectively, the day-residue and dream-lag effects). In experiment 1, 44 participants kept a daily log for 10 days, reporting major daily activities (MDAs), personally significant events (PSEs), and major concerns (MCs). Dream reports were collected from REM and Slow Wave Sleep (SWS) in the laboratory, or from REM sleep at home. The dream-lag effect was found for the incorporation of PSEs into REM dreams collected at home, but not for MDAs or MCs. No dream-lag effect was found for SWS dreams, or for REM dreams collected in the lab after SWS awakenings earlier in the night. In experiment 2, the 44 participants recorded reports of their spontaneously recalled home dreams over the 10 nights following the instrumental awakenings night, which thus acted as a controlled stimulus with two salience levels, high (sleep lab) and low (home awakenings). The dream-lag effect was found for the incorporation into home dreams of references to the experience of being in the sleep laboratory, but only for participants who had reported concerns beforehand about being in the sleep laboratory. The delayed incorporation of events from daily life into dreams has been proposed to reflect REM sleep-dependent memory consolidation. However, an alternative emotion processing or emotional impact of events account, distinct from memory consolidation, is supported by the finding that SWS dreams do not evidence the dream-lag effect.

Incorporation of details from waking life events into rapid eye movement (REM) sleep dreams has been found to be highest on the 2 nights after, and then 5-7 nights after, the event. These are termed, respectively, the day-residue and dream-lag effects. This study is the first to categorize types of waking life experiences and compare their incorporation into dreams across multiple successive nights. Thirty-eight participants completed a daily diary each evening and a dream diary each morning for 14 days. In the daily diary, three categories of experiences were reported: major daily activities (MDAs), personally significant events (PSEs) and major concerns (MCs). After the 14-day period each participant identified the correspondence between items in their daily diaries and subsequent dream reports. The day-residue and dream-lag effects were found for the incorporation of PSEs into dreams (effect sizes of .33 and .27, respectively), but only for participants (n = 19) who had a below-median total number of correspondences between daily diary items and dream reports (termed "low-incorporators" as opposed to "high-incorporators"). Neither the day-residue or dream-lag effects were found for MDAs or MCs. This U-shaped timescale of incorporation of events from daily life into dreams has been proposed to reflect REM sleep-dependent memory consolidation, possibly related to emotional memory processing. This study had a larger sample size of dreams than any dream-lag study hitherto with trained participants. Coupled with previous successful replications, there is thus substantial evidence supporting the dream-lag effect and further explorations of its mechanism, including its neural underpinnings, are warranted. © 2018 The Authors.

Perverse dreams and dreams of perversion.

This paper (1) posits the occurrence of perverse dreams as a type of mental phenomenon in the constellation of perverse processes; (2) considers manifest dreams of frank perversion as a type of perverse dream within the class of perverse dreams as a whole; (3) relates the subtype of perverse dreams without manifest perversions to the occurrence of perverse defenses and the development of a perverse transference; and (4) suggests that consideration to perverse dreams in the psychoanalytic process finds application in identifying and differentiating perverse defenses from neurotic and other characterologic patterns; in identifying and tracing the vicissitudes of difficult perverse transference-countertransference constellations; and in furthering perverse patients' recognition and understanding of particularly troublesome and seemingly intractable issues in their psychic makeup. Clinical material illustrates perverse dreams and their usefulness in the often arduous process of analyzing perverse defenses.

The Curious Connection Between Insects and Dreams

2011-01-01

A majority of humans spend their waking hours surrounded by insects, so it should be no surprise that insects also appear in humans’ dreams as we sleep. Dreaming about insects has a peculiar history, marked by our desire to explain a dream’s significance and by the tactic of evoking emotions by injecting insects in dream-related works of art, film, music, and literature. I surveyed a scattered literature for examples of insects in dreams, first from the practices of dream interpretation, psychiatry, and scientific study, then from fictional writings and popular culture, and finally in the etymology of entomology by highlighting insects with dream-inspired Latinate names. A wealth of insects in dreams, as documented clinically and culturally, attests to the perceived relevance of dreams and to the ubiquity of insects in our lives. PMID:26467945

Trauma-related dreams of Australian veterans with PTSD: content, affect and phenomenology.

2011-10-01

Consensus on the parameters of trauma-related dreams required to meet criteria for post-traumatic stress disorder (PTSD) is critical when: (i) the diagnosis requires a single re-experiencing symptom; and (ii) trauma dreams are prevalent in survivors without PTSD. This study investigated the phenomenology of PTSD dreams in 40 veterans, using structured interview and self-report measures. Dream content varied between replay, non-replay, and mixed, but affect was largely the same as that experienced at the time of trauma across all dream types. ANOVA indicated no difference between dream types on PTSD severity or nightmare distress. The findings provide preliminary support for non-replay dreams to satisfy the DSM B2 diagnostic criterion when the affect associated with those dreams is the same as that experienced at the time of the traumatic event.

[The dream as a tool in diagnosis, healing and life orientation in antiquity].

PubMed

Strunz, F

1994-10-01

The dream is usually discussed in connection with the work of Freud und Jung and the dreamlore initiated by these two eminent dream scientists. Therefore the dream knowledge gathered by investigators of classical antiquity is almost forgotten, although the same diagnostic and therapeutic aims have been followed by them as they are by modern psychotherapy and medicine. Hippocrates and the other Greek physicians saw in dreams indications of bodily and psychosomatic disturbances. Dreams from the gods, especially Ascelepios, helped those who travelled from afar to be healed while sleeping in the temples. Popular dream interpretation availed itself of just as sophisticated an interpretative system as has been set up by modern depth psychologists. Dreams served to give orientation in life and warn of fateful future events. In spite of its elusive quality truth is sought in dreams today as it was in antiquity. Dream interpretation was then, and is now, one of the preferential techniques of existence.

Dreaming and personality: Wake-dream continuity, thought suppression, and the Big Five Inventory.

PubMed

Malinowski, Josie E

2015-12-15

Studies have found relationships between dream content and personality traits, but there are still many traits that have been underexplored or have had questionable conclusions drawn about them. Experimental work has found a 'rebound' effect in dreams when thoughts are suppressed prior to sleep, but the effect of trait thought suppression on dream content has not yet been researched. In the present study participants (N=106) reported their Most Recent Dream, answered questions about the content of the dream, and completed questionnaires measuring trait thought suppression and the 'Big Five' personality traits. Of these, 83 were suitably recent for analyses. A significant positive correlation was found between trait thought suppression and participants' ratings of dreaming of waking-life emotions, and high suppressors reported dreaming more of their waking-life emotions than low suppressors did. The results may lend support to the compensation theory of dreams, and/or the ironic process theory of mental control. Copyright © 2015 Elsevier Inc. All rights reserved.

Approach/avoidance in dreams.

PubMed

Malcolm-Smith, Susan; Koopowitz, Sheri; Pantelis, Eleni; Solms, Mark

2012-03-01

The influential threat simulation theory (TST) asserts that dreaming yields adaptive advantage by providing a virtual environment in which threat-avoidance may be safely rehearsed. We have previously found the incidence of biologically threatening dreams to be around 20%, with successful threat avoidance occurring in approximately one-fifth of such dreams. TST asserts that threat avoidance is over-represented relative to other possible dream contents. To begin assessing this issue, we contrasted the incidence of 'avoidance' dreams with that of their opposite: 'approach' dreams. Because TST states that the threat-avoidance function is only fully activated in ecologically valid (biologically threatening) contexts, we also performed this contrast for populations living in both high- and low-threat environments. We find that 'approach' dreams are significantly more prevalent across both contexts. We suggest these results are more consistent with the view that dreaming is generated by reward-seeking systems than by fear-conditioning systems, although reward-seeking is clearly not the only factor determining the content of dreams.

A template model of embodiment while dreaming: Proposal of a mini-me.

Koppehele-Gossel, Judith; Klimke, Ansgar; Schermelleh-Engel, Karin; Voss, Ursula

2016-11-01

Dreams are usually centered around a dream self capable of tasks generally impossible in waking, e.g. flying or walking through walls. Moreover, the bodily dream self appears relatively stable and insensitive to changes of the embodied wake self, raising the question of whether and to what extent the dream self is embodied. To further explore its determinants, we tested whether the dream self would be affected by either pre-sleep focused attention to a body part or by its experimental alteration during the day. Choosing a repeated-measures design, we analyzed how often key words reflecting the experimental manipulations appeared in the dream reports. Results suggest that the dream self is not affected by these manipulations, strengthening the hypothesis that, in the majority of dreams, the dream self is only weakly embodied, utilizing a standard template of embodiment akin to a prototype of self operating independently from the physical waking self.

Lucid dreams: their advantage and disadvantage in the frame of search activity concept

PubMed Central

Rotenberg, Vadim S.

2015-01-01

Search activity (SA) is the behavioral and mental activity that is oriented to changes of the environment or of the subject's view and approach to the environment according to personal needs without the definite probability forecast of the outcomes of such activity, but with a regular consideration of the outcomes in the process of active behavior. Dream's lucidity (the subject's realization that he/she is dreaming) protects dreamer from awakenings during emotionally disturbing or frustrating dreams, because lucid dreams allow subject to feel separated from the dream events that may cause a feeling of helplessness. Due to such a protection from awakenings that can bring subject back to the frustration in wakefulness, subject can turn in the further sleep to normal non-lucid dreams that are restoring subject's SA in the subsequent wakefulness (activity in the uncertain situation with the feedback between behavior and its outcome). It is the advantage of lucid dreams. Their disadvantage is that due to the separation from the dream events that are in lucid dreams accepted as rationalized dreams, not as real stories where the dreamer acts like in wakefulness, their ability to restore SA is decreased until they are not displaced by the normal non-lucid dreams accepted as real stories.

Sleep disturbances have long been considered as a cardinal symptom of endogenous depression and dreams in depressed patients usually differ from those of healthy people. The aim of the present study was to investigate dream subjective experiences and their modifications in relation to clinical response in a group of escitalopram-treated depressed patients. Twenty-seven female patients meeting DSM-IV-TR criteria for Major Depressive Disorder (MDD) and starting SSRI therapy were included in the study. Data about psychopathological status and dreaming subjective experiences were collected at baseline (T0), 4 weeks after the beginning of the treatment (T1) and after further 4 weeks of therapy (T2). At T0 dream experience was impaired and negatively toned. Concomitantly with the decrease of symptoms severity, the 8-week escitalopram treatment yielded to significant improvements in the recall of both quantity and quality of dreams; those patients whit lower clinical benefits kept on reporting impaired dream experiences. The results of the present study evidence how the changes in some specific dreaming characteristics, such as the subjective recall of dream activity, the dream recall quality, the dream emotional content and the dream complexity represent reliable markers of the effectiveness of antidepressant therapy.

Metacognitive mechanisms underlying lucid dreaming.

Filevich, Elisa; Dresler, Martin; Brick, Timothy R; Kühn, Simone

2015-01-21

Lucid dreaming is a state of awareness that one is dreaming, without leaving the sleep state. Dream reports show that self-reflection and volitional control are more pronounced in lucid compared with nonlucid dreams. Mostly on these grounds, lucid dreaming has been associated with metacognition. However, the link to lucid dreaming at the neural level has not yet been explored. We sought for relationships between the neural correlates of lucid dreaming and thought monitoring. Human participants completed a questionnaire assessing lucid dreaming ability, and underwent structural and functional MRI. We split participants based on their reported dream lucidity. Participants in the high-lucidity group showed greater gray matter volume in the frontopolar cortex (BA9/10) compared with those in the low-lucidity group. Further, differences in brain structure were mirrored by differences in brain function. The BA9/10 regions identified through structural analyses showed increases in blood oxygen level-dependent signal during thought monitoring in both groups, and more strongly in the high-lucidity group. Our results reveal shared neural systems between lucid dreaming and metacognitive function, in particular in the domain of thought monitoring. This finding contributes to our understanding of the mechanisms enabling higher-order consciousness in dreams. Copyright © 2015 the authors 0270-6474/15/351082-07$15.00/0.

Anesthetic dreaming and anesthesia awareness are well distinct phenomena. Although the incidence of intraoperative awareness is more common among patients who reported a dream after surgery, the exact correlation between the two phenomena remains an unsolved rebus. The main purpose of this study was to investigate anesthetic dreaming, anesthesia awareness and psychological consequences eventually occurred under deep sedation. Intraoperative dreaming experiences were correlated with dream features in natural sleep. Fifty-one patients, undergoing surgical excision of fibroadenomas under a Bispectral index-guided deep sedation anesthesia with propofol target controlled infusion, were enrolled into this prospective study. Psychological assessment was performed through the State Trait Anxiety Inventory. A questionnaire was adopted to register dreaming and anesthesia awareness. Data were collected after emergence (t0), 24 hours (t1), 1 month (t2), 6 months (t3). Six patients (12%) reported anesthetic dreaming at t0 confirming the response at each subsequent evaluation. One patient (2%) confirmed dreaming during anesthesia in all, but denied it at t0. There was a high correlation between the intraoperative dream contents and the features of dreams in natural sleep. No cases of anesthesia awareness were detected. A similar level of satisfaction was observed in dreaming and no-dreaming patients. Anesthetic dreaming does not seem to influence satisfaction of patients undergoing deep sedation with propofol target controlled infusion. A psychological assessment would seem to improve the evaluation of possible psychological consequences in dreamer patient.

The current study presents an integrated uncertainty analysis and data assimilation approach to improve streamflow predictions while simultaneously providing meaningful estimates of the associated uncertainty. Study models include the National Weather Service (NWS) operational snow model (SNOW17) and rainfall-runoff model (SAC-SMA). The proposed approach uses the recently developed DiffeRential Evolution Adaptive Metropolis (DREAM) to simultaneously estimate uncertainties in model parameters, forcing, and observations. An ensemble Kalman filter (EnKF) is configured with the DREAM-identified uncertainty structure and applied to assimilating snow water equivalent data into the SNOW17 model for improved snowmelt simulations. Snowmelt estimates then serves as an input to the SAC-SMA model to provide streamflow predictions at the basin outlet. The robustness and usefulness of the approach is evaluated for a snow-dominated watershed in the northern Sierra Mountains. This presentation describes the implementation of DREAM and EnKF into the coupled SNOW17 and SAC-SMA models and summarizes study results and findings.

DREAM DIAGNOSTICS: FRITZ MORGENTHALER'S WORK ON DREAMS.

The unique approach to dreams of Swiss psychoanalyst Fritz Morgenthaler (1919-1984) is presented and discussed. Although rarely discussed in the English-speaking psychoanalytic world, this approach is very alive in German-speaking countries. Focusing on the distinction between the remembered hallucinatory experience of dreamers and the event of telling dreams within psychoanalytic sessions, Morgenthaler made two major innovations: first, he proposed a new understanding and handling of associations to dreams, and second, he offered what he called dream diagnostics as an instrument with which to integrate both resistance and transference into clinical work with dreams. © 2016 The Psychoanalytic Quarterly, Inc.

Exploring the dreams of hospice workers.

Hess, Shirley A; Knox, Sarah; Hill, Clara E; Byers, Tara; Spangler, Patricia

2014-06-01

Nine adults who worked at least 1 year with patients at US hospice centers completed an in-person audiotaped dream session focusing on a dream about a patient. Data were analyzed using consensual qualitative research. Patients were generally manifestly present in participants' dreams, and dreams were typically realistic (i.e., not bizarre). In the dream, the dreamer typically interacted with the patient as a caretaker but was also typically frustrated by an inability to help as fully as desired. Dreams gave dreamers insight into the stress of hospice work, their own fears of death, and inter-/intrapersonal interactions beyond hospice work. Dreamers generally sought to take better care of themselves and find balance in their lives after the dream session. Implications for research and practice are discussed.

During stock market losses in 2009 and high unemployment, ratings on the KJP Dream Inventory were correlated with factors of the Money Attitude Scale and items on the Contemporary Financial Stress Inventory for 71 graduate students in Counseling Psychology and Education. Correlations were significant for Retention on the Money Attitude Scale with Dissociative Avoidance (-.31), Dreams of falling (.26), Risk-taking in dreams (.24), and Dreaming of being chased (.28). Also, ratings for the Money Attitude Scale of Distrust correlated with Discontentedness in dreams (.33) and Dreams of being chased (.26), Repetitive trauma (.33), Nightmares (.30), and Recurring nightmares (.35). Concern about retention in graduate school due to finances correlated with recalled frequencies of nightmares (.27) and dreams of flying (.25).

Dream content: Individual and generic aspects.

PubMed

Hobson, Allan; Kahn, David

2007-12-01

Dream reports were collected from normal subjects in an effort to determine the degree to which dream reports can be used to identify individual dreamers. Judges were asked to group the reports by their authors. The judges scored the reports correctly at chance levels. This finding indicated that dreams may be at least as much like each other as they are the signature of individual dreamers. Our results suggest that dream reports cannot be used to identify the individuals who produced them when identifiers like names and gender of friends and family members are removed from the dream report. In addition to using dreams to learn about an individual, we must look at dreams as telling us about important common or generic aspects of human consciousness.

[Configuration of the dream in REM sleep].

PubMed

Leonhard, K

1985-02-01

Dreams during REM sleep have a characteristic form. They are, so to speak, "chain dreams, in which the scenes follow consecutively and, although distinctly separate from each other, are welded into a coherent dream by the primary integrating thoughts underlying the dream. The contents of the different scenes are difficult to reconcile with the integrating thought behind the dream because they are not stimulated by the thought alone but, in a certain way, also by past experiences. The author describes a dream which apparently filled the REM phase from beginning to end. It has been possible to explain the background of the integrating thought and the origins of the different scenes. The peculiar character of such dreams should find more attention in scientific research.

The dream in contemporary psychiatry.

PubMed

Reiser, M F

2001-03-01

This article offers selective reviews of cogent sectors of research regarding the dream in contemporary psychiatry. First, the author discusses relatively recent research (1953-1999) on the neurobiology and clinical psychophysiology of dreaming sleep; second, he reviews experimental cognitive neuroscientific studies of perception, emotion, and memory and the putative interrelationships among them in generating dream imagery; and third, he interprets psychoanalytic studies (1900-1999) on related aspects of dreams and the dream process. Exploration for interrelationships among information from these three areas entails discussion of the mind/brain problem. These considerations illuminate some of the logical and interpretive dilemmas that enter into debates about Freud's theory of the dream. The author proposes a preliminary psychobiologic concept of the dream process and discusses, in light of the foregoing considerations, the importance of collaborative research for developing a realistic perspective concerning the proper place of the dream in contemporary psychiatry.

Regulation of DREAM Expression by Group I mGluR

PubMed Central

Lee, Jinu; Kim, Insook; Oh, So Ra; Ko, Suk Jin; Lim, Mi Kyung; Kim, Dong Goo

2011-01-01

DREAM (downstream regulatory element antagonistic modulator) is a calcium-binding protein that regulates dynorphin expression, promotes potassium channel surface expression, and enhances presenilin processing in an expression level-dependent manner. However, no molecular mechanism has yet explained how protein levels of DREAM are regulated. Here we identified group I mGluR (mGluR1/5) as a positive regulator of DREAM protein expression. Overexpression of mGluR1/5 increased the cellular level of DREAM. Up-regulation of DREAM resulted in increased DREAM protein in both the nucleus and cytoplasm, where the protein acts as a transcriptional repressor and a modulator of its interacting proteins, respectively. DHPG (3,5-dihydroxyphenylglycine), a group I mGluR agonist, also up-regulated DREAM expression in cortical neurons. These results suggest that group I mGluR is the first identified receptor that may regulate DREAM activity in neurons. PMID:21660149

Autobiographical memory sources of threats in dreams.

2018-02-01

Temporal sources of dream threats were examined through the paradigm of the Threat Simulation Theory. Two groups of young adults (18-24 years old), who did not experience severe threatening events in the year preceding their dream and reported a dream either with or without threats, were included. Participants (N = 119) kept a log of daily activities and a dream diary, indicating whether dream components referred to past experiences. The occurrence of oneiric threats correlated with the reporting of threats in the daily logs, their average severity, and the stress level experienced the day preceding the dream. The group whose dreams contained threats had significantly more references to temporal categories beyond one year than the group with dreams without threats. Our findings suggest that in the absence of recent highly negative emotional experiences, the threat simulation system selects memory traces of threatening events experienced in the past.

Recurrent Dreams and Psychosocial Adjustment in Preteenaged Children

Gauchat, Aline; Zadra, Antonio; Tremblay, Richard E.; Zelazo, Philip David; Séguin, Jean R.

2014-01-01

Research indicates that recurrent dreams in adults are associated with impoverished psychological well-being. Whether similar associations exist in children remains unknown. The authors hypothesized that children reporting recurrent dreams would show poorer psychosocial adjustment than children without recurrent dreams. One hundred sixty-eight 11-year-old children self-reported on their recurrent dreams and on measures of psychosocial adjustment. Although 35% of children reported having experienced a recurrent dream during the past year, our hypothesis was only partially supported. Multivariate analyses revealed a marginally significant interaction between gender and recurrent dream presence and a significant main effect of gender. Univariate analyses revealed that boys reporting recurrent dreams reported significantly higher scores on reactive aggression than those who did not (d = 0.58). This suggests that by age 11 years, the presence of recurrent dreams may already reflect underlying emotional difficulties in boys but not necessarily in girls. Challenges in addressing this developmental question are discussed. PMID:24976740

On Dreams and Motivation: Comparison of Freud's and Hobson's Views.

PubMed

Boag, Simon

2016-01-01

The merits of Freudian dream theory continue to be debated and both supporters and critics appeal to empirical evidence to support their respective positions. What receives much less attention is the theoretical coherency of either Freudian dream theory or alternative perspectives. This paper examines Freudian dream theory and J. Allan Hobson's alternative position by addressing the role of motivation in dreams. This paper first discusses motivation in Freudian theory and its relation to dreams and disguise-censorship. The role of motivation in Hobson's theory is then considered. Hobson's claim that dream plot and content selection is random and based on design error and functional imbalance is then discussed in relation to the protoconsciousness theory proposal that dreams serve an adaptive function. While there are apparent inconsistencies in Hobson's position, his appeal to emotions and instincts provides a preliminary platform for understanding the role of motivation in dreams that is consonant with the Freudian position.

Threat in dreams: an adaptation?

Revonsuo's influential Threat Simulation Theory (TST) predicts that people exposed to survival threats will have more threat dreams, and evince enhanced responses to dream threats, compared to those living in relatively safe conditions. Participants in a high crime area (South Africa: n=208) differed significantly from participants in a low crime area (Wales, UK: n=116) in having greater recent exposure to a life-threatening event (chi([1,N=186])(2)=14.84, p<.00012). Contrary to TST's predictions, the SA participants reported significantly fewer threat dreams (chi([1,N=287])(2)=6.11, p<.0134), and did not differ from the Welsh participants in responses to dream threats (Fisher's Exact test, p=.2478). Overall, the incidence of threat in dreams was extremely low-less than 20% of dreams featured realistic survival threats. Escape from dream threats occurred in less than 2% of dreams. We conclude that this evidence contradicts key aspects of TST.

Consciousness never fades during waking. However, when awakened from sleep, we sometimes recall dreams and sometimes recall no experiences. Traditionally, dreaming has been identified with rapid eye-movement (REM) sleep, characterized by wake-like, globally 'activated', high-frequency electroencephalographic activity. However, dreaming also occurs in non-REM (NREM) sleep, characterized by prominent low-frequency activity. This challenges our understanding of the neural correlates of conscious experiences in sleep. Using high-density electroencephalography, we contrasted the presence and absence of dreaming in NREM and REM sleep. In both NREM and REM sleep, reports of dream experience were associated with local decreases in low-frequency activity in posterior cortical regions. High-frequency activity in these regions correlated with specific dream contents. Monitoring this posterior 'hot zone' in real time predicted whether an individual reported dreaming or the absence of dream experiences during NREM sleep, suggesting that it may constitute a core correlate of conscious experiences in sleep.

Dreaming and waking experiences in schizophrenia: how should the (dis)continuity hypotheses be approached empirically?

PubMed

Noreika, Valdas

2011-06-01

A number of differences between the dreams of schizophrenia patients and those of healthy participants have been linked to changes in waking life that schizophrenia may cause. This way, the "continuity hypothesis" has become a standard way to relate dreaming and waking experiences in schizophrenia. Nevertheless, some of the findings in dream literature are not compatible with the continuity hypothesis and suggest some other ways how dream content and waking experiences could interact. Conceptually, the continuity hypothesis could be sharpened into the "waking-to-dreaming" and the "dreaming-to-waking" hypotheses, whereas a less explored type of "discontinuity" could embrace the "compensated waking" and the "compensated dreaming" hypotheses. A careful consideration and empirical testing of each of those hypotheses may reveal a multiplicity of the ways how dreaming and waking life interact in schizophrenia. Copyright © 2010 Elsevier Inc.

Cognitive and emotional processes during dreaming: a neuroimaging view.

PubMed

Desseilles, Martin; Dang-Vu, Thien Thanh; Sterpenich, Virginie; Schwartz, Sophie

2011-12-01

Dream is a state of consciousness characterized by internally-generated sensory, cognitive and emotional experiences occurring during sleep. Dream reports tend to be particularly abundant, with complex, emotional, and perceptually vivid experiences after awakenings from rapid eye movement (REM) sleep. This is why our current knowledge of the cerebral correlates of dreaming, mainly derives from studies of REM sleep. Neuroimaging results show that REM sleep is characterized by a specific pattern of regional brain activity. We demonstrate that this heterogeneous distribution of brain activity during sleep explains many typical features in dreams. Reciprocally, specific dream characteristics suggest the activation of selective brain regions during sleep. Such an integration of neuroimaging data of human sleep, mental imagery, and the content of dreams is critical for current models of dreaming; it also provides neurobiological support for an implication of sleep and dreaming in some important functions such as emotional regulation.

Memory sources of dreams: the incorporation of autobiographical rather than episodic experiences.

PubMed

Malinowski, Josie E; Horton, Caroline L

2014-08-01

The present study aimed to explore autobiographical memories (long-lasting memories about the self) and episodic memories (memories about discrete episodes or events) within dream content. We adapted earlier episodic memory study paradigms and reinvestigated the incorporation of episodic memory sources into dreams, operationalizing episodic memory as featuring autonoetic consciousness, which is the feeling of truly re-experiencing or reliving a past event. Participants (n = 32) recorded daily diaries and dream diaries, and reported on wake-dream relations for 2 weeks. Using a new scale, dreams were rated for their episodic richness, which categorized memory sources of dreams as being truly episodic (featuring autonoetic consciousness), autobiographical (containing segregated features of experiences that pertained to waking life) or otherwise. Only one dream (0.5%) was found to contain an episodic memory. However, the majority of dreams (>80%) were found to contain low to moderate incorporations of autobiographical memory features. These findings demonstrate the inactivity of intact episodic memories, and emphasize the activity of autobiographical memory and processing within dreams. Taken together, this suggests that memories for personal experiences are experienced fragmentarily and selectively during dreaming, perhaps in order to assimilate these memories into the autobiographical memory schema. © 2014 European Sleep Research Society.

[Dreams in normal and pathological aging].

PubMed

Guénolé, Fabian; Marcaggi, Geoffrey; Baleyte, Jean-Marc; Garma, Lucile

2010-06-01

Although most of scientific knowledge in dream research is based on young adult studies, this article provides a review of the effects of normal and pathological aging on dream psychology. It starts with preliminary comments about epistemological and methodological principles of dream research, its singularities in aged persons, and the modifications of sleep physiology with age. The whole literature agrees that dream recall progressively decreases from the beginning of adulthood - not in old age - and that dream reports become less intense, perceptually and emotionally. This evolution occurs faster in men than women, with gender differences in the content of dreams. The chronological modifications could be explained partly by changes in lifestyle and attitude towards dreams in early adulthood, but mainly by modifications of sleep physiology, particularly the decrease and qualitative changes of rapid eye movement (REM) sleep. Dreams have usually little subjective importance in the mental life of aged persons. However, working with dreams can be a valuable tool for psychotherapy in the aged. According to the few existing data, patients suffering degenerative dementia dream much less than healthy aged persons. In Alzheimer's disease, this could be linked to the decrease of REM sleep, and atrophy of associative sensory areas of the cerebral cortex. Most studied aspects of dreaming in degenerative cognitive disorders are REM sleep behavior disorders, and nightmares induced by cholinesterase inhibitors. More studies are needed to better characterize the evolution of dreams with age, particularly studies performed in sleep laboratory.

A consideration of ketamine dreams.

PubMed

Hejja, P; Galloon, S

1975-01-01

This study was designed to see whether covering of the eyes during and after ketamine anaesthesia would reduce the incidence of dreams. One hundred and fifty patients, randomly divided into three groups, underwent therapeutic abortion with ketamine as the sole anaesthesia. One hundred patients had their eyes completely covered, 50 in the operating room only and 50 in the operating room and in the recovery room. The third 50 were controls, with their eyes uncovered. All patients were questioned post-operatively about dreams, nausea and vomiting, headache, dizziness and experiences, and also how frequently they dreamed at home. Although covering the eyes in the recovery room only reduced the incidence of dreams marginally, it became obvious that the patients who dreamed after ketamine (in all 3 groups) were those who normally dreamed at home. There were 82 patients who were recorded as not being home-dreamers, and only two of these dreamed after ketamine. In contrast, of the 68 home-dreamers, 50 dreamed after ketamine, and 17 of these had unpleasant dreams. In the home-dreamers, covering the eyes reduced the incidence of dreams from 86 per cent in Group 1 to 72 per cent in Group 2 and 64 per cent in Group 3. It is suggested that goggles may be advantageous when dealing with home-dreamers, and a question about the patient's tendency to dream should be included in the preoperative questioning. Alterations in premedication and the use of a quiet dark room during recovery may even further reduce unpleasant dreams in this group.

Increased Evoked Potentials to Arousing Auditory Stimuli during Sleep: Implication for the Understanding of Dream Recall

High dream recallers (HR) show a larger brain reactivity to auditory stimuli during wakefulness and sleep as compared to low dream recallers (LR) and also more intra-sleep wakefulness (ISW), but no other modification of the sleep macrostructure. To further understand the possible causal link between brain responses, ISW and dream recall, we investigated the sleep microstructure of HR and LR, and tested whether the amplitude of auditory evoked potentials (AEPs) was predictive of arousing reactions during sleep. Participants (18 HR, 18 LR) were presented with sounds during a whole night of sleep in the lab and polysomnographic data were recorded. Sleep microstructure (arousals, rapid eye movements (REMs), muscle twitches (MTs), spindles, KCs) was assessed using visual, semi-automatic and automatic validated methods. AEPs to arousing (awakenings or arousals) and non-arousing stimuli were subsequently computed. No between-group difference in the microstructure of sleep was found. In N2 sleep, auditory arousing stimuli elicited a larger parieto-occipital positivity and an increased late frontal negativity as compared to non-arousing stimuli. As compared to LR, HR showed more arousing stimuli and more long awakenings, regardless of the sleep stage but did not show more numerous or longer arousals. These results suggest that the amplitude of the brain response to stimuli during sleep determine subsequent awakening and that awakening duration (and not arousal) is the critical parameter for dream recall. Notably, our results led us to propose that the minimum necessary duration of an awakening during sleep for a successful encoding of dreams into long-term memory is approximately 2 min.

Dreams enacted during sleepwalking or sleep terrors (SW/ST) may differ from those enacted during rapid eye movement sleep behavior disorder (RBD). Subjects completed aggression, depression, and anxiety questionnaires. The mentations associated with SW/ST and RBD behaviors were collected over their lifetime and on the morning after video polysomnography (PSG). The reports were analyzed for complexity, length, content, setting, bizarreness, and threat. Ninety-one percent of 32 subjects with SW/ST and 87.5% of 24 subjects with RBD remembered an enacted dream (121 dreams in a lifetime and 41 dreams recalled on the morning). These dreams were more complex and less bizarre, with a higher level of aggression in the RBD than in SW/ST subjects. In contrast, we found low aggression, anxiety, and depression scores during the daytime in both groups. As many as 70% of enacted dreams in SW/ST and 60% in RBD involved a threat, but there were more misfortunes and disasters in the SW/ST dreams and more human and animal aggressions in the RBD dreams. The response to these threats differed, as the sleepwalkers mostly fled from a disaster (and 25% fought back when attacked), while 75% of RBD subjects counterattacked when assaulted. The dreams setting included their bedrooms in 42% SW/ST dreams, though this finding was exceptional in the RBD dreams. Different threat simulations and modes of defense seem to play a role during dream-enacted behaviors (e.g., fleeing a disaster during SW/ST, counterattacking a human or animal assault during RBD), paralleling and exacerbating the differences observed between normal dreaming in nonrapid eye movement (NREM) vs rapid eye movement (REM) sleep.

To explore associations between dream recall, gender, sleep, perceived stress, and creativity in a large sample of adolescents. In adults, women report a higher frequency of dream recall than men. Moreover, increased awakenings seem to increase dream recall, whereas low sleep quality is associated with low dream recall. In addition, there is some evidence that dream recall is associated with personality traits such as creativity. For adolescents, comparable data from larger samples are missing to date. A total of 5,580 adolescents (mean age: 18.23 years; 3,711 females and 1,869 males) participated in the present study. Participants completed an Internet-administered questionnaire related to dreaming, sleep, perceived stress, and creativity. As compared with males, female adolescents reported a higher dream recall rate and felt a stronger impact of dreams on the subsequent day. Female adolescents also described themselves as more creative, and reported suffering more from sleep complaints and perceived stress. Multiple regression analyses further revealed that increased dream recall was independently predicted by factors such as female gender, sleep quality, and creativity, whereas perceived stress, awakenings during the night, and sleep duration had no predictive value. Similar to the findings of studies conducted on adults, dream recall was also associated with female gender in a large sample of adolescents. Additionally, it seemed that several different factors such as good mood, increased sleep quality, and creativity influenced dream recall. These results can provide a basis for better understanding the psychology of dreams in adolescence. In contrast to nightmares, recalling dreaming is associated with health and well-being.

Dreaming as a 'curtain of illusion': revisiting the 'royal road' with Bion as our guide.

PubMed

Grotstein, James S

2009-08-01

One of Bion's most unique contributions to psychoanalysis is his conception of dreaming in which he elaborates, modifies, and extends Freud 's ideas. While Freud dealt extensively with dream-work, he showed more interest in dreams themselves and their latent meaning and theorized that dreams ultimately constituted wish-fulfillments originating from the activity of the pleasure principle. Bion, on the other hand, focuses more on the process of dreaming itself and believes that dreaming occurs throughout the day as well as the night and serves the reality principle as well as the pleasure principle. In order for wakeful consciousness to occur, dreaming must absorb (contain) the day residue, and transfer it to System Ucs. from System Cs. for it to be processed (transformed) and then returned to System Cs. through the selectively-permeable contact-barrier. Dreaming, consequently, allows the subject to remain awake by day and asleep by night by its processing of the day's residue. Bion seems to conceive of dreaming as an ever-present invisible filter that overlays much of our mental life, including perception, as well as attention itself. He further believes that dreaming is a form of thinking that normally involves the collaborative yet oppositional (not conflictual) activity of the reality and pleasure principles as well as the primary and secondary processes. He also conflates Freud 's primary and secondary processes into a single 'binary-oppositional' structure (Lévi-Strauss, 1958, 1970) that he terms 'alpha-function', which constitutes a virtual model that corresponds to the in-vivo activity of dreaming. He further believes that the analyst dreams as he or she listens and interprets and that the analysand likewise dreams while he or she freely associates.

The effects of an auditory subliminal message upon the production of images and dreams.

PubMed

Kaser, V A

1986-07-01

The purpose of this research was to investigate what effect an auditory subliminal message, produced by speeding up the rate at which it was recorded, would have upon the imagery and dreams of a group of normal subjects. The auditory subliminal message was produced by speeding up a message that was sung until it could not be consciously understood. This message was mixed with a normal music recording and played to nine subjects in the experimental group. Nine subjects in the control group heard the normal music recording without the subliminal message. Both groups were asked to produce a pretest drawing before the tapes were played, an imagery drawing immediately after the tapes were played, and a dream drawing of any dreams they might have that night. A statistical analysis was performed from data collected on blind ratings given to all the drawings by two art therapists. The results indicated a significant difference between the dream drawings and the imagery drawings of the experimental group and the control group. When the drawings were examined, the effect of the subliminal message could be seen. Based on the statistical data and certain drawings collected in this study, it would appear that the auditory subliminal message did have an effect upon the imagery and dreams of the subjects in the experimental group. The results of this study appear to indicate that the unconscious/preconscious mind is able to perceive a recorded verbal message that cannot be consciously understood at the high rate of speed at which it was recorded.

The threat simulation theory of the evolutionary function of dreaming: Evidence from dreams of traumatized children.

The threat simulation theory of dreaming (TST) () states that dream consciousness is essentially an ancient biological defence mechanism, evolutionarily selected for its capacity to repeatedly simulate threatening events. Threat simulation during dreaming rehearses the cognitive mechanisms required for efficient threat perception and threat avoidance, leading to increased probability of reproductive success during human evolution. One hypothesis drawn from TST is that real threatening events encountered by the individual during wakefulness should lead to an increased activation of the system, a threat simulation response, and therefore, to an increased frequency and severity of threatening events in dreams. Consequently, children who live in an environment in which their physical and psychological well-being is constantly threatened should have a highly activated dream production and threat simulation system, whereas children living in a safe environment that is relatively free of such threat cues should have a weakly activated system. We tested this hypothesis by analysing the content of dream reports from severely traumatized and less traumatized Kurdish children and ordinary, non-traumatized Finnish children. Our results give support for most of the predictions drawn from TST. The severely traumatized children reported a significantly greater number of dreams and their dreams included a higher number of threatening dream events. The dream threats of traumatized children were also more severe in nature than the threats of less traumatized or non-traumatized children.

Suppressing unwanted thoughts can lead to an increased occurrence of the suppressed thought in dreams. This is explainable by the ironic control theory, which theorizes why the suppression of thoughts might make them more persistent. The present study examined the influence of thought suppression on dream rebound, dream distress, general psychiatric symptomatology, depression, sleep quality and perceived stress. Thirty healthy participants (good sleepers) were investigated over a period of 1 week. Half were instructed to suppress an unwanted thought 5 min prior to sleep, whereas the other half were allowed to think of anything at all. Dream content was assessed through a dream diary. Independent raters assessed whether or not the dreams were related to the suppressed target thought. The results demonstrated increased target-related dreams and a tendency to have more distressing dreams in the suppression condition. Moreover, the data imply that thought suppression may lead to significantly increased general psychiatric symptomatology. No significant effects were found for the other secondary outcomes. © 2013 European Sleep Research Society.

Dreaming and recall during sedation for colonoscopy.

PubMed

Stait, M L; Leslie, K; Bailey, R

2008-09-01

Dreaming is reported by one in five patients who are interviewed on emergence from general anaesthesia, but the incidence, predictors and consequences of dreaming during procedural sedation are not known. In this prospective observational study, 200 patients presenting for elective colonoscopy under intravenous sedation were interviewed on emergence to determine the incidences of dreaming and recall. Sedation technique was left to the discretion of the anaesthetist. The incidence of dreaming was 25.5%. Patients reporting dreaming were younger than those who did not report dreaming. Doses of midazolam and fentanyl were similar between dreamers and non-dreamers, however propofol doses were higher in patients who reported dreams than those who did not. Patients reported short, simple dreams about everyday life--no dream suggested near-miss recall of the procedure. Frank recall of the procedure was reported by 4% of the patients, which was consistent with propofol doses commensurate with light general anaesthesia. The only significant predictor of recall was lower propofol dose. Satisfaction with care was generally high, however dreamers were more satisfied with their care than non-dreamers.

From the dreams of a generation to the theory of dreams: Freud's Roman dreams.

Meghnagi, David

2011-06-01

In The Interpretation of Dreams, Freud's interpretation of oedipal desires does not occur at the expense of historical and personal desires, which are always there as a backdrop. In the relentless examination of his own dreams that Freud makes in order to show the mechanisms inherent in all oneiric deformation, we are also led to another, specifically historical, aspect of the issue of Jewish emancipation, which he experiences at first hand. By analysing his own dreams, Freud not only shows us the mechanisms governing dream formation, but also develops a pointed critique of his contemporary society and its prejudices.

Driver behavior in car-to-pedestrian incidents: An application of the Driving Reliability and Error Analysis Method (DREAM).

PubMed

2013-01-01

To develop relevant road safety countermeasures, it is necessary to first obtain an in-depth understanding of how and why safety-critical situations such as incidents, near-crashes, and crashes occur. Video-recordings from naturalistic driving studies provide detailed information on events and circumstances prior to such situations that is difficult to obtain from traditional crash investigations, at least when it comes to the observable driver behavior. This study analyzed causation in 90 video-recordings of car-to-pedestrian incidents captured by onboard cameras in a naturalistic driving study in Japan. The Driving Reliability and Error Analysis Method (DREAM) was modified and used to identify contributing factors and causation patterns in these incidents. Two main causation patterns were found. In intersections, drivers failed to recognize the presence of the conflict pedestrian due to visual obstructions and/or because their attention was allocated towards something other than the conflict pedestrian. In incidents away from intersections, this pattern reoccurred along with another pattern showing that pedestrians often behaved in unexpected ways. These patterns indicate that an interactive advanced driver assistance system (ADAS) able to redirect the driver's attention could have averted many of the intersection incidents, while autonomous systems may be needed away from intersections. Cooperative ADAS may be needed to address issues raised by visual obstructions. Copyright © 2012 Elsevier Ltd. All rights reserved.

Experimental Research on Dreaming: State of the Art and Neuropsychoanalytic Perspectives

PubMed Central

Ruby, Perrine M.

2011-01-01

Dreaming is still a mystery of human cognition, although it has been studied experimentally for more than a century. Experimental psychology first investigated dream content and frequency. The neuroscientific approach to dreaming arose at the end of the 1950s and soon proposed a physiological substrate of dreaming: rapid eye movement sleep. Fifty years later, this hypothesis was challenged because it could not explain all of the characteristics of dream reports. Therefore, the neurophysiological correlates of dreaming are still unclear, and many questions remain unresolved. Do the representations that constitute the dream emerge randomly from the brain, or do they surface according to certain parameters? Is the organization of the dream’s representations chaotic or is it determined by rules? Does dreaming have a meaning? What is/are the function(s) of dreaming? Psychoanalysis provides hypotheses to address these questions. Until now, these hypotheses have received minimal attention in cognitive neuroscience, but the recent development of neuropsychoanalysis brings new hopes of interaction between the two fields. Considering the psychoanalytical perspective in cognitive neuroscience would provide new directions and leads for dream research and would help to achieve a comprehensive understanding of dreaming. Notably, several subjective issues at the core of the psychoanalytic approach, such as the concept of personal meaning, the concept of unconscious episodic memory and the subject’s history, are not addressed or considered in cognitive neuroscience. This paper argues that the focus on singularity and personal meaning in psychoanalysis is needed to successfully address these issues in cognitive neuroscience and to progress in the understanding of dreaming and the psyche.

Warning dreams preceding the diagnosis of breast cancer: a survey of the most important characteristics.

PubMed

Burk, Larry

2015-01-01

There are rare reports of warning dreams about breast cancer in the dream literature and even fewer in the medical literature. Anxiety about breast cancer is increasing due to uncertainty about conflicting guidelines regarding mammography screening. The purpose of the study was to survey women with breast cancer who had warning dreams prior to diagnosis to determine the most common and important characteristics of these dreams. Eighteen women with a known diagnosis of breast cancer completed a survey of 19 Yes or No questions about their warning dreams and submitted dream narratives. The five most common characteristics of warning dreams in descending order of frequency reported in the survey were: a sense of conviction about the importance in 94%; the dreams were more vivid, real or intense than ordinary in 83%; an emotional sense of threat, menace or dread in 72%; the use of the specific words breast cancer/tumor in 44%; and the sense of physical contact with the breast in 39%. Warning dreams of breast cancer were often reported to be life changing experiences that prompted medical attention leading directly to diagnosis. Further research needs to be done to determine the frequency of such dreams in women without known breast cancer in order to assess the predictive value of a warning dream. These preliminary results suggest that keeping a dream diary might be a useful adjunct to routine self-examination as part of a breast self-care program, particularly for women in a high-risk category.

Dreaming during anesthesia and anesthetic depth in elective surgery patients: a prospective cohort study.

Leslie, Kate; Skrzypek, Hannah; Paech, Michael J; Kurowski, Irina; Whybrow, Tracey

2007-01-01

Dreaming reported after anesthesia remains a poorly understood phenomenon. Dreaming may be related to light anesthesia and represent near-miss awareness. However, few studies have assessed the relation between dreaming and depth of anesthesia, and their results were inconclusive. Therefore, the authors tested the hypothesis that dreaming during anesthesia is associated with light anesthesia, as evidenced by higher Bispectral Index values during maintenance of anesthesia. With approval, 300 consenting healthy patients, aged 18-50 yr, presenting for elective surgery requiring relaxant general anesthesia with a broad range of agents were studied. Patients were interviewed on emergence and 2-4 h postoperatively. The Bispectral Index was recorded from induction until the first interview. Dream content and form were also assessed. Dreaming was reported by 22% of patients on emergence. There was no difference between dreamers and nondreamers in median Bispectral Index values during maintenance (37 [23-55] vs. 38 [20-59]; P=0.68) or the time at Bispectral Index values greater than 60 (0 [0-7] vs. 0 [0-31] min; P=0.38). Dreamers tended to be younger and male, to have high home dream recall, to receive propofol maintenance or regional anesthesia, and to open their eyes sooner after surgery. Most dreams were similar to dreams of sleep and were pleasant, and the content was unrelated to surgery. Dreaming during anesthesia is unrelated to the depth of anesthesia in almost all cases. Similarities with dreams of sleep suggest that anesthetic dreaming occurs during recovery, when patients are sedated or in a physiologic sleep state.

Can multiple sclerosis as a cognitive disorder influence patients’ dreams?

PubMed Central

Owji, Mahsa

2013-01-01

Dream should be considered as a kind of cognitive ability that is formed parallel to other cognitive capabilities like language. On the other hand, multiple sclerosis (MS) is a complex disease that can involve different aspects of our cognition. Therefore, MS may influence patients’ dreams. In fact, we do not know what the importance of dream is in MS, but further studies may introduce dream and dreaming as a sign of improvement or progression in MS disease. PMID:24250908

Unconscious cathexis of dream symbols as measured by the Kahn Test of Symbol Arrangement.

Webb, D E; Craddick, R A

1993-10-01

This study measured unconscious cathexis and conscious association with dream content, using the Kahn Test of Symbol Arrangement (KTSA), with subjects reporting recurring, past-recurring, and nonrecurring dreams. Unconscious cathexis of dream content was noted for recurring dreamers; conscious association with dream content was not. The results suggest that the KTSA is a valuable instrument for the empirical study of unconscious processes and that the contents of recurring dreams are particularly salient in a dreamer's unconscious.

Strengths and weaknesses of McNamara's evolutionary psychological model of dreaming.

Olliges, Sandra

2010-10-07

This article includes a brief overview of McNamara's (2004) evolutionary model of dreaming. The strengths and weaknesses of this model are then evaluated in terms of its consonance with measurable neurological and biological properties of dreaming, its fit within the tenets of evolutionary theories of dreams, and its alignment with evolutionary concepts of cooperation and spirituality. McNamara's model focuses primarily on dreaming that occurs during rapid eye movement (REM) sleep; therefore this article also focuses on REM dreaming.

Frightening dreams and dosage schedule of tricyclic and neuroleptic drugs.

PubMed

Strayhorn, J M; Nash, J L

1978-12-01

One previous study reported that psychiatric inpatients on bedtime-only doses of tricyclic or neuroleptic drugs reported more frequent frightening dreams than did those on divided daily doses. As a further test of this hypothesis, and in order to see whether differences in frequency of frightening dreams were a function of differences in total dream recall, we administered a questionnaire to outpatients in a Veterans Administration Hospital Mental Hygiene Clinic, asking about frequency of dream recall, frequency of frightening dream recall, and doses and times of any medications taken. Questionnaire reports of medications were checked with the medical record of the patient; for 48 patients on tricyclic or neuroleptic drugs the reports agreed, and the data of these patients were analyzed. Our findings corroborated the previous report of more frequent frightening dreams in patients on bedtime-only dosage schedules (p less than .01). In addition, we found no significant difference between the two groups with respect to frequency of dream recall; thus a difference in the affect of dreams, rather than a difference in quantity of dream recall, constituted the difference between the two groups. When a patient on bedtime doses of tricyclic or neuroleptic drugs has undesirable frightening dreams, the clinician should consider a change to divided daily doses.

An association between geomagnetic activity and dream bizarreness.

PubMed

Lipnicki, Darren M

2009-07-01

Daily disturbances of the earth's magnetic field produce variations in geomagnetic activity (GMA) that are reportedly associated with widespread effects on human health and behaviour. Some of these effects could be mediated by an established influence of GMA on the secretion of melatonin. There is evidence from unrelated research that melatonin influences dream bizarreness, and it is hypothesised here that there is an association between GMA and dream bizarreness. Also reported is a preliminary test of this hypothesis, a case study in which the dreams recorded over 6.5 years by a young adult male were analysed. Reports of dreams from the second of two consecutive days of either low or high GMA (K index sum < or =6 or > or = 28) were self-rated for bizarreness on a 1-5 scale. Dreams from low GMA periods (n=69, median bizarreness=4) were found to be significantly more bizarre than dreams from high GMA periods (n=85, median bizarreness=3; p=0.006), supporting the hypothesised association between GMA and dream bizarreness. Studies with larger samples are needed to verify this association, and to determine the extent to which melatonin may be involved. Establishing that there is an association between GMA and dream bizarreness would have relevance for neurophysiological theories of dreaming, and for models of psychotic symptoms resembling bizarre dream events.

Meteors in Australian Aboriginal Dreamings

Hamacher, Duane W.; Norris, Ray P.

2010-06-01

We present a comprehensive analysis of Australian Aboriginal accounts of meteors. The data used were taken from anthropological and ethnographic literature describing oral traditions, ceremonies, and Dreamings of 97 Aboriginal groups representing all states of modern Australia. This revealed common themes in the way meteors were viewed between Aboriginal groups, focusing on supernatural events, death, omens, and war. The presence of such themes around Australia was probably due to the unpredictable nature of meteors in an otherwise well-ordered cosmos.

Freud's struggle with misogyny: homosexuality and guilt in the dream of Irma's injection.

PubMed

Lotto, D

2001-01-01

The highly condensed dream element trimethylamin is central to the dream of Irma's injection. After a brief review of the medical literature on timethylamine (TMA), it is suggested that two important meanings of this chemical and its properties lie in its disguised reference to disparaging views of women, as well as to Freud's homosexual connection to Wilhelm Fliess. Freud's misogynistic and homosexual impulses were stimulated by Fliess's recent surgical error committed while operating on Freud's patient Emma Eckstein. Evidence is presented that the collaboration between Freud and Fliess in performing an aggressive act toward a woman was for Freud an enactment of a childhood situation in which he and his nephew John had ganged up on John's sister Pauline. The later relationship between Freud, Jung, and Sabina Spielrein is seen as an additional reenactment of this childhood triangle. An examination of Freud's associations to and analysis of the Irma dream, as well as some of his later relationships with women, indicates that guilt and the wish to make reparation were also prominent themes in Freud's inner life.

2014-10-01

We tested whether dreams can anticipate a stressful exam and how failure/success in dreams affect next-day performance. We collected information on students' dreams during the night preceding the medical school entrance exam. Demographic, academic, sleep and dream characteristics were compared to the students' grades on the exam. Of the 719 respondents to the questionnaire (of 2324 total students), 60.4% dreamt of the exam during the night preceding it. Problems with the exam appeared in 78% of dreams and primarily involved being late and forgetting answers. Reporting a dream about the exam on the pre-exam night was associated with better performance on the exam (p=.01). The frequency of dreams concerning the exam during the first term predicted proportionally higher performance on the exam (R=0.1, p=.01). These results suggest that the negative anticipation of a stressful event in dreams is common and that this episodic simulation provides a cognitive gain. Copyright © 2014 Elsevier Inc.

Seemingly precognitive (prophetic) dreams may be a result of one's unconscious processing of environmental cues and having an implicit inference based on these cues manifest itself in one's dreams. We present two studies exploring this implicit processing hypothesis of precognitive dream experience. Study 1 investigated the relationship between implicit learning, transliminality, and precognitive dream belief and experience. Participants completed the Serial Reaction Time task and several questionnaires. We predicted a positive relationship between the variables. With the exception of relationships between transliminality and precognitive dream belief and experience, this prediction was not supported. Study 2 tested the hypothesis that differences in the ability to notice subtle cues explicitly might account for precognitive dream beliefs and experiences. Participants completed a modified version of the flicker paradigm. We predicted a negative relationship between the ability to explicitly detect changes and precognitive dream variables. This relationship was not found. There was also no relationship between precognitive dream belief and experience and implicit change detection. Copyright © 2014 Elsevier Inc. All rights reserved.

On Dreams and Motivation: Comparison of Freud’s and Hobson’s Views

PubMed Central

Boag, Simon

2017-01-01

The merits of Freudian dream theory continue to be debated and both supporters and critics appeal to empirical evidence to support their respective positions. What receives much less attention is the theoretical coherency of either Freudian dream theory or alternative perspectives. This paper examines Freudian dream theory and J. Allan Hobson’s alternative position by addressing the role of motivation in dreams. This paper first discusses motivation in Freudian theory and its relation to dreams and disguise-censorship. The role of motivation in Hobson’s theory is then considered. Hobson’s claim that dream plot and content selection is random and based on design error and functional imbalance is then discussed in relation to the protoconsciousness theory proposal that dreams serve an adaptive function. While there are apparent inconsistencies in Hobson’s position, his appeal to emotions and instincts provides a preliminary platform for understanding the role of motivation in dreams that is consonant with the Freudian position.

Linking psychological need experiences to daily and recurring dreams.

Weinstein, Netta; Campbell, Rachel; Vansteenkiste, Maarten

2018-01-01

The satisfaction of individuals' psychological needs for autonomy, competence, and relatedness, as conceived from a self-determination theory perspective, is said to be conducive to personal growth and well-being. What has been unexamined is whether psychological need-based experiences, either their satisfaction or frustration, manifests in people's self-reported dream themes as well as their emotional interpretation of their dreams. A cross-sectional study ( N  = 200; M age = 21.09) focusing on individuals' recurrent dreams and a three-day diary study ( N  = 110; M age = 25.09) focusing on daily dreams indicated that individuals experiencing psychological need frustration, either more enduringly or on a day-to-day basis, reported more negative dream themes and interpreted their dreams more negatively. The contribution of psychological need satisfaction was more modest, although it related to more positive interpretation of dreams. The discussion focuses on the role of dreams in the processing and integration of psychological need-frustrating experiences.

Dreaming and cognition in patients with frontotemporal dysfunction.

2011-12-01

Individuals with Parkinson's disease (PD) and temporal lobe epilepsy (TLE) have hallucinations and mild cognitive dysfunction. The objective of this work was to study dreams in PD and TLE patients using a common functional model of dream production involving the limbic and paralimbic structures. Dreams were characterised in early-stage PD (19 males) and TLE patients (52) with dream diaries classified by the Hall van de Castle system and were compared with matched controls. In PD, there were significant differences between patients' dreams and those of controls: animals, physical aggression, and a befriender were more common in patients, and aggressor and bodily misfortunes were less common. The dreams of patients with frontal dysfunction showed more aggressive features. TLE patients had lower recall than PD patients and a higher proportion of dreams involving family and familiar settings, lower proportions involving success, and a higher incidence of frontal dysfunction. The dreams of PD and TLE patients share important features. Copyright © 2011. Published by Elsevier Inc.

Neural correlates of insight in dreaming and psychosis.

2015-04-01

The idea that dreaming can serve as a model for psychosis has a long and honourable tradition, however it is notoriously speculative. Here we demonstrate that recent research on the phenomenon of lucid dreaming sheds new light on the debate. Lucid dreaming is a rare state of sleep in which the dreamer gains insight into his state of mind during dreaming. Recent electroencephalogram (EEG) and functional magnetic resonance imaging (fMRI) data for the first time allow very specific hypotheses about the dream-psychosis relationship: if dreaming is a reasonable model for psychosis, then insight into the dreaming state and insight into the psychotic state should share similar neural correlates. This indeed seems to be the case: cortical areas activated during lucid dreaming show striking overlap with brain regions that are impaired in psychotic patients who lack insight into their pathological state. This parallel allows for new therapeutic approaches and ways to test antipsychotic medication. Copyright © 2014 Elsevier Ltd. All rights reserved.

Impact of REM sleep on distortions of self-concept, mood and memory in depressed/anxious participants

PubMed Central

McNamara, Patrick; Auerbach, Sanford; Johnson, Patricia; Harris, Erica; Doros, Gheorghe

2009-01-01

Introduction: We tested the hypothesis that REM sleep contributes to core features of cognitive dysfunction of anxious depression including negative self-appraisals, biased memory processing and unpleasant dream content. Methods: After a habituation night in a sleep lab, a convenience sample of 35 healthy college students and 20 depressed/anxious students were awakened 10 minutes into a REM sleep episode and then 10 minutes into a NREM sleep episode. Awakenings were counterbalanced to control circadian effects. After each awakening participants reported a dream and then completed memory recall, mood and self-appraisal tasks. Results: Self-appraisals of depressed/anxious participants were significantly less positive and significantly more negative after awakenings from REM sleep vs NREM sleep. Appraisal of the REM sleep dream self was negative for depressed/anxious subjects only. Recall of negative memories was significantly more frequent after REM vs NREM sleep awakenings for both depress/anxious and healthy participants. REM sleep dreams were associated with greater frequencies of negative emotion, greater aggression and victimization rates than dreams in NREM sleep for depressed/anxious participants. Limitations: Depressed/anxious participants were classified as such on the basis of mood scales rather than clinical interview. All participants were drawn from a volunteer college student population and thus our results may not be applicable to some elderly clinical populations. Conclusions: REM appears to facilitate cognitive distortions of anxious depression. PMID:19631989

The canary in the mind: on the fate of dreams in psychoanalysis and in contemporary culture.

Lippmann, Paul

2006-06-01

Dreams have been central in the birth and evolution of psychoanalysis. This paper explores the remarkable story of the relationship between dreams and psychoanalysis as a modern version of the long history of dreams in most healing traditions. But psychoanalysis seems to have turned away from dreams as central inspiration in a way parallel to the general culture's turn away from dreams and the reality of inner life. Yet modern postindustrial culture is transfixed by a version of "dream life" in ways just beginning to be understood (e.g., in the transformation of ancient interest in the inner screen to the external screen). Working with dreams in psychoanalytic psychotherapy was a creative and revolutionary act for our forebears. It is even more so today, in ways that are discussed in this paper.

Dream Content in Complicated Grief: A Window into Loss-Related Cognitive Schemas Running Head: Dreams in Complicated Grief

2012-01-01

Bereavement and its accompanying psychological response (grief) constitute potent experiences that necessitate the reorganization of cognitive-affective representations of lost significant attachment figures during both wakefulness and dreaming. The goals of this preliminary study were to explore whether the dream content of 77 adults with complicated grief (CG) differed from that of a normative sample, and to explore whether CG patients who dream of the deceased differ from CG patients who do not dream of the deceased on measures of daytime emotional distress. CG dreams were characterized by more family and familiar characters including the deceased (in women), and fewer social interactions and emotions compared to norms. Increased representations of familiar characters in CG dreams may reflect attempts to reorganize relational cognitive schemas to compensate for the loss. PMID:24524436

Similarities and differences between dreaming and waking cognition: an exploratory study.

Kahan, T L; LaBerge, S; Levitan, L; Zimbardo, P

1997-03-01

Thirty-eight "practiced" dreamers (Study 1) and 50 "novice" dreamers (Study 2) completed questionnaires assessing the cognitive, metacognitive, and emotional qualities of recent waking and dreaming experiences. The present findings suggest that dreaming cognition is more similar to waking cognition than previously assumed and that the differences between dreaming and waking cognition are more quantitative than qualitative. Results from the two studies were generally consistent, indicating that high-order cognition during dreaming is not restricted to individuals practiced in dream recall or self-observation. None of the measured features was absent or infrequent in reports of either dreaming or waking experiences. Recollections of dreaming and waking experiences were similar for some cognitive features (e.g., attentional processes, internal commentary, and public self-consciousness) and different for other features (e.g., choice, event-related self-reflection, and affect).

Freud's private mini-monograph on his own dreams. A contribution to the celebration of the centenary of The interpretation of dreams.

PubMed

Blum, H P

2001-10-01

A virtually unknown brief commentary by Freud on the characteristics of his own dreams is described and discussed. Freud's mini-monograph, discovered after some 80 years, has autobiographical, theoretical and organisational significance in the enigmatic context of the early development of psychoanalysis. Found among papers of Alfred Adler, this extraordinary document adds to our knowledge of psychoanalytic history, including the significance of dreams in the evolution of psychoanalytic thought. Freud's commentary permitted the identification of a particular dream as his own. This dream had been presented in anonymity to the fledgling Vienna Psychoanalytic Society for interpretation. The dream was later inserted, again anonymously, into The Interpretation of Dreams with Freud's own remarkable pre-oedipal interpretation. Freud's conflicted relationships with Adler and Jung are considered in historical context.

Metaphor and hyperassociativity: the imagination mechanisms behind emotion assimilation in sleep and dreaming

PubMed Central

Malinowski, Josie E.; Horton, Caroline L.

2015-01-01

In this paper we propose an emotion assimilation function of sleep and dreaming. We offer explanations both for the mechanisms by which waking-life memories are initially selected for processing during sleep, and for the mechanisms by which those memories are subsequently transformed during sleep. We propose that emotions act as a marker for information to be selectively processed during sleep, including consolidation into long term memory structures and integration into pre-existing memory networks; that dreaming reflects these emotion assimilation processes; and that the associations between memory fragments activated during sleep give rise to measureable elements of dream metaphor and hyperassociativity. The latter are a direct reflection, and the phenomenological experience, of emotional memory assimilation processes occurring during sleep. While many theories previously have posited a role for emotion processing and/or emotional memory consolidation during sleep and dreaming, sleep theories often do not take enough account of important dream science data, yet dream research, when conducted systematically and under ideal conditions, can greatly enhance theorizing around the functions of sleep. Similarly, dream theories often fail to consider the implications of sleep-dependent memory research, which can augment our understanding of dream functioning. Here, we offer a synthesized view, taking detailed account of both sleep and dream data and theories. We draw on extensive literature from sleep and dream experiments and theories, including often-overlooked data from dream science which we believe reflects sleep phenomenology, to bring together important ideas and findings from both domains.

Hierarchical Neural Representation of Dreamed Objects Revealed by Brain Decoding with Deep Neural Network Features.

PubMed

Horikawa, Tomoyasu; Kamitani, Yukiyasu

2017-01-01

Dreaming is generally thought to be generated by spontaneous brain activity during sleep with patterns common to waking experience. This view is supported by a recent study demonstrating that dreamed objects can be predicted from brain activity during sleep using statistical decoders trained with stimulus-induced brain activity. However, it remains unclear whether and how visual image features associated with dreamed objects are represented in the brain. In this study, we used a deep neural network (DNN) model for object recognition as a proxy for hierarchical visual feature representation, and DNN features for dreamed objects were analyzed with brain decoding of fMRI data collected during dreaming. The decoders were first trained with stimulus-induced brain activity labeled with the feature values of the stimulus image from multiple DNN layers. The decoders were then used to decode DNN features from the dream fMRI data, and the decoded features were compared with the averaged features of each object category calculated from a large-scale image database. We found that the feature values decoded from the dream fMRI data positively correlated with those associated with dreamed object categories at mid- to high-level DNN layers. Using the decoded features, the dreamed object category could be identified at above-chance levels by matching them to the averaged features for candidate categories. The results suggest that dreaming recruits hierarchical visual feature representations associated with objects, which may support phenomenal aspects of dream experience.

The majority of women develop sleep impairments during pregnancy, but alterations in dream experiences remain poorly understood. This study aimed to assess prospectively and comparatively the recall of dreaming and of disturbed dreaming in late pregnancy. Fifty-seven nulliparous, third-trimester pregnant women (mean age±SD, 28.7±4.06 years) and 59 non-pregnant controls (mean age±SD, 26.8±4.21 years) completed demographics and psychological questionnaires. A 14-day prospective home log assessed sleep and dream characteristics and the Sleep Disorders Questionnaire measured retrospective dream and disturbed dream recall. Even though pregnant and non-pregnant women showed similar prospective dream recall (P=0.47), pregnant women reported prospectively more bad dreams (P=0.004). More pregnant women (21%) than non-pregnant women (7%) reported a nightmare incidence exceeding moderately severe pathology (>1/week) (P=0.03). Pregnant women also reported overall lower sleep quality (P=0.007) and more night awakenings (P=0.003). Higher prospective recall of bad dreams (r = -0.40, P=0.002) and nightmares (r = -0.32, P=0.001) both correlated with lower sleep quality in pregnant women. Late pregnancy is a period of markedly increased dysphoric dream imagery that may be a major contributor to impaired sleep at this time. Further polysomnographic assessments of pregnant women are needed to clarify relationships between sleep and disturbed dream production in this population. Copyright © 2014 Elsevier B.V.

2015-05-01

Nightmares are a frequent symptom in narcolepsy. Lucid dreaming, i.e., the phenomenon of becoming aware of the dreaming state during dreaming, has been demonstrated to be of therapeutic value for recurrent nightmares. Data on lucid dreaming in narcolepsy patients, however, is sparse. The aim of this study was to evaluate the frequency of recalled dreams (DF), nightmares (NF), and lucid dreams (LDF) in narcolepsy patients compared to healthy controls. In addition, we explored if dream lucidity provides relief during nightmares in narcolepsy patients. We interviewed patients with narcolepsy and healthy controls. Telephone interview. 60 patients diagnosed with narcolepsy (23-82 years, 35 females) and 919 control subjects (14-93 years, 497 females). N/A. Logistic regression revealed significant (P < 0.001) differences in DF, NF, and LDF between narcolepsy patients and controls after controlling for age and gender, with effect sizes lying in the large range (Cohen's d > 0.8). The differences in NF and LDF between patients and controls stayed significant after controlling for DF. Comparison of 35 narcolepsy patients currently under medication with their former drug-free period revealed significant differences in DF and NF (z < 0.05, signed-rank test) but not LDF (z = 0.8). Irrespective of medication, 70% of narcolepsy patients with experience in lucid dreaming indicated that dream lucidity provides relief during nightmares. Narcolepsy patients experience a markedly higher lucid dreaming frequency compared to controls, and many patients report a positive impact of dream lucidity on the distress experienced from nightmares. © 2015 Associated Professional Sleep Societies, LLC.

Metaphor and hyperassociativity: the imagination mechanisms behind emotion assimilation in sleep and dreaming.

PubMed

Malinowski, Josie E; Horton, Caroline L

2015-01-01

In this paper we propose an emotion assimilation function of sleep and dreaming. We offer explanations both for the mechanisms by which waking-life memories are initially selected for processing during sleep, and for the mechanisms by which those memories are subsequently transformed during sleep. We propose that emotions act as a marker for information to be selectively processed during sleep, including consolidation into long term memory structures and integration into pre-existing memory networks; that dreaming reflects these emotion assimilation processes; and that the associations between memory fragments activated during sleep give rise to measureable elements of dream metaphor and hyperassociativity. The latter are a direct reflection, and the phenomenological experience, of emotional memory assimilation processes occurring during sleep. While many theories previously have posited a role for emotion processing and/or emotional memory consolidation during sleep and dreaming, sleep theories often do not take enough account of important dream science data, yet dream research, when conducted systematically and under ideal conditions, can greatly enhance theorizing around the functions of sleep. Similarly, dream theories often fail to consider the implications of sleep-dependent memory research, which can augment our understanding of dream functioning. Here, we offer a synthesized view, taking detailed account of both sleep and dream data and theories. We draw on extensive literature from sleep and dream experiments and theories, including often-overlooked data from dream science which we believe reflects sleep phenomenology, to bring together important ideas and findings from both domains.

We explored how acculturation and self-actualization affect depression in the HIV-positive Asians and Pacific Islanders immigrant population. Asians and Pacific Islanders are among the fastest growing minority groups in the USA. Asians and Pacific Islanders are the only racial/ethnic group to show a significant increase in HIV diagnosis rate. A mixed-methods study was conducted. Thirty in-depth interviews were conducted with HIV-positive Asians and Pacific Islanders in San Francisco and New York. Additionally, cross-sectional audio computer-assisted self-interviews were conducted with a sample of 50 HIV-positive Asians and Pacific Islanders. Content analysis was used to analyse the in-depth interviews. Also, descriptive, bivariate statistics and multivariable regression analysis was used to estimate the associations among depression, acculturation and self-actualization. The study took place from January-June 2013. Major themes were extracted from the interview data, including self-actualization, acculturation and depression. The participants were then divided into three acculturation levels correlating to their varying levels of self-actualization. For those with low acculturation, there was a large discrepancy in the Center for Epidemiologic Studies Depression Scale scores between those who had totally lost their self-actualization and those who believed they could still achieve their 'American dreams'. Among those who were less acculturated, there was a significant difference in depression scores between those who felt they had totally lost their ability to self-actualize and those who still believed they could 'make their dreams come true.' Acculturation levels influence depression and self-actualization in the HIV-positive Asians and Pacific Islanders population. Lower acculturated Asian Americans achieved a lower degree of self-actualization and suffered from depression. Future interventions should focus on enhancing acculturation and reducing depression to achieve self-actualization. © 2015 John Wiley & Sons Ltd.

The marginalisation of dreams in clinical psychological practice.

PubMed

Leonard, Linda; Dawson, Drew

2018-04-22

The longstanding human interest in dreams has led to a significant body of psychological and philosophical discourse, including research. Recently, however, dreams have been relegated to the periphery of clinical psychological practice. This is potentially problematic as clients continue to bring dreams to therapy and many psychologists lack the confidence or competence to respond effectively to dream material. Building on the structural, professional and research cultures surrounding psychology using a cultural-historical activity theory framework, we argue the marginalisation of dreams is due to cultural-historical factors. These factors include the political and economic context in which psychology developed; psychology's early attempts to differentiate from psychoanalysis by identifying with behaviourism and the natural sciences; and a discipline-specific definition of what constitutes evidence-based practice. These factors led to professional discourses within which dreams are seen as of little clinical or therapeutic value, or that dream work is only for long-term therapy and requires extensive therapist training. However, there are diverse models of dream work consistent with most theoretical orientations within contemporary psychological practice. We conclude with recommendations on how to rebuild clinical confidence and competence in the use of dream material within the current professional environment. Copyright © 2018 Elsevier Ltd.

Recalling and forgetting dreams: theta and alpha oscillations during sleep predict subsequent dream recall.

Under the assumption that dream recall is a peculiar form of declarative memory, we have hypothesized that (1) the encoding of dream contents during sleep should share some electrophysiological mechanisms with the encoding of episodic memories of the awake brain and (2) recalling a dream(s) after awakening from non-rapid eye movement (NREM) and rapid eye movement (REM) sleep should be associated with different brain oscillations. Here, we report that cortical brain oscillations of human sleep are predictive of successful dream recall. In particular, after morning awakening from REM sleep, a higher frontal 5-7 Hz (theta) activity was associated with successful dream recall. This finding mirrors the increase in frontal theta activity during successful encoding of episodic memories in wakefulness. Moreover, in keeping with the different EEG background, a different predictive relationship was found after awakening from stage 2 NREM sleep. Specifically, a lower 8-12 Hz (alpha) oscillatory activity of the right temporal area was associated with a successful dream recall. These findings provide the first evidence of univocal cortical electroencephalographic correlates of dream recall, suggesting that the neurophysiological mechanisms underlying the encoding and recall of episodic memories may remain the same across different states of consciousness.

Exploring the effects of galantamine paired with meditation and dream reliving on recalled dreams: Toward an integrated protocol for lucid dream induction and nightmare resolution.

An experimental home study examined the impact of a pre-sleep protocol for enhancing self-awareness, lucidity, and responsiveness in dreams. It included ingesting the cholinesterase inhibitor galantamine--which is widely reported to increase the frequency of lucid dreaming--prior to engaging in middle-of-the-night meditation and the imaginary reliving of a distressing dream while exercising new responses. Thirty-five participants completed an eight-night study, which included pre- and post-baseline nights and six conditions: waking for 40 min before returning to bed, called Wake-Back-to-Bed (WBTB); Wake-Back-to-Bed plus placebo (WBTB + P); Wake-Back-to-Bed plus galantamine (WBTB + G); meditation and dream reliving (MDR); meditation and dream reliving plus placebo (MDR + P); and meditation and dream reliving plus galantamine (MDR + G). The outcome measures included lucidity, reflectiveness, interactive behavior, role change, constructive action, and fear and threat, as measured by the participants' self-ratings. The results support the use of this protocol in further studies of lucid dream induction and nightmare/trauma resolution. Copyright © 2018 Elsevier Inc. All rights reserved.

Memory in dreams.

PubMed

Giustino, Gabriella

2009-10-01

In this paper the author discusses a specific type of dreams encountered in her clinical experience, which in her view provide an opportunity of reconstructing the traumatic emotional events of the patient's past. In 1900, Freud described a category of dreams--which he called 'biographical dreams'--that reflect historical infantile experience without the typical defensive function. Many authors agree that some traumatic dreams perform a function of recovery and working through. Bion contributed to the amplification of dream theory by linking it to the theory of thought and emphasizing the element of communication in dreams as well as their defensive aspect. The central hypothesis of this paper is that the predominant aspect of such dreams is the communication of an experience which the dreamer has in the dream but does not understand. It is often possible to reconstruct, and to help the patient to comprehend and make sense of, the emotional truth of the patient's internal world, which stems from past emotional experience with primary objects. The author includes some clinical examples and references to various psychoanalytic and neuroscientific conceptions of trauma and memory. She discusses a particular clinical approach to such dreams and how the analyst should listen to them.

Images evoked immediately before the induction of anesthesia by means of suggestions may influence dreaming during anesthesia. This study is a retrospective re-evaluation of the original prospective randomized trial. Dream reports were studied in two groups. In group 1. dreams of patients who received suggestions, and in group 2, those of the control group of patients who did not. The incidence of dream reports and the characteristics and the theme of the reported dreams were compared among the groups. In general, the control and the psychological intervention groups were different in terms of dreaming frequency, and non-recall dreaming. The incidence of dream reports was significantly higher in the suggestion group (82/190 at 10 min and 71/190 at 60 min respectively) than in the control group (16/80 at 10 min and 13/80 at 60 min, respectively; p10 = 0.001 and p60 = 0.002). There were no differences in the nature (thought- like or cinematic), quality (color or B&W) and the mood (positive vs. negative) of the recalled dreams. In general, the contents of the imaginary favorite place and the reported dream were identical in 73.2 %. Among the topics most successfully applied in the operating theater were loved ones (83.8 %), holiday (77.8 %) and sport (63.6 %). The results of the present study suggest that dreams during anesthesia are influenced by suggestions administered immediately preceding anesthesia. The study was registered in ClinicalTrials.gov.

This article reviews recent findings indicating some common brain processes during dissociative states and dreaming with the aim to outline a perspective that neural chaotic states during dreaming can be closely related to dissociative states that may manifest in dreams scenery. These data are in agreement with various clinical findings that dissociated states can be projected into the “dream scenery” in REM sleep periods and dreams may represent their specific interactions that may uncover unusual psychological potential of creativity in psychotherapy, art, and scientific discoveries.

Dreams have produced art, music, novels, films, mathematical proofs, designs for architecture, telescopes, and computers. Dreaming is essentially our brain thinking in another neurophysiologic state-and therefore it is likely to solve some problems on which our waking minds have become stuck. This neurophysiologic state is characterized by high activity in brain areas associated with imagery, so problems requiring vivid visualization are also more likely to get help from dreaming. This article reviews great historical dreams and modern laboratory research to suggest how dreams can aid creativity and problem-solving. © 2017 New York Academy of Sciences.

Lucid Dreaming: A State of Consciousness with Features of Both Waking and Non-Lucid Dreaming

2009-01-01

Study Objectives: The goal of the study was to seek physiological correlates of lucid dreaming. Lucid dreaming is a dissociated state with aspects of waking and dreaming combined in a way so as to suggest a specific alteration in brain physiology for which we now present preliminary but intriguing evidence. We show that the unusual combination of hallucinatory dream activity and wake-like reflective awareness and agentive control experienced in lucid dreams is paralleled by significant changes in electrophysiology. Design: 19-channel EEG was recorded on up to 5 nights for each participant. Lucid episodes occurred as a result of pre-sleep autosuggestion. Setting: Sleep laboratory of the Neurological Clinic, Frankfurt University. Participants: Six student volunteers who had been trained to become lucid and to signal lucidity through a pattern of horizontal eye movements. Measurements and Results: Results show lucid dreaming to have REM-like power in frequency bands δ and θ, and higher-than-REM activity in the γ band, the between-states-difference peaking around 40 Hz. Power in the 40 Hz band is strongest in the frontal and frontolateral region. Overall coherence levels are similar in waking and lucid dreaming and significantly higher than in REM sleep, throughout the entire frequency spectrum analyzed. Regarding specific frequency bands, waking is characterized by high coherence in α, and lucid dreaming by increased δ and θ band coherence. In lucid dreaming, coherence is largest in frontolateral and frontal areas. Conclusions: Our data show that lucid dreaming constitutes a hybrid state of consciousness with definable and measurable differences from waking and from REM sleep, particularly in frontal areas.

In a lucid dream, the dreamer is aware of the dream state and can deliberately practice motor skills. Two field studies indicated that lucid dream practice can improve waking performance in simple motor tasks. The present pilot study investigated the effect of lucid dream practice in a controlled sleep laboratory setting, using a pre-post design with dart throwing in the evening and morning. The experimental group practiced darts in lucid dreams. Because some participants were distracted during lucid dream practice, the group was divided into lucid dreamers with few (n = 4) and many distractions (n = 5). Change of performance was compared to a physical practice group (n = 9) and a control group (n = 9), showing a significant interaction (P = .013, η 2  = .368). Only the lucid dreamers with few distractions improved (18%) significantly over time (P = .005, d = 3.84). Even though these results have to be considered preliminary, the present study indicates that lucid dream practice can be an effective tool in sports practice if lucid dreamers find ways to minimise distractions during lucid dream practice. Moreover, the study emphasises the necessity to investigate lucid dream practice experiences on a qualitative level.

Transcriptional repressor DREAM (downstream regulatory element antagonist modulator) is a Ca(2+)-binding protein that regulates Ca(2+) homeostasis through gene regulation and protein-protein interactions. It has been shown that a dominant active form (daDREAM) is implicated in learning-related synaptic plasticity such as LTP and LTD in the hippocampus. Neuronal spines are reported to play important roles in plasticity and memory. However, the possible role of DREAM in spine plasticity has not been reported. Here we show that potentiating DREAM activity, by overexpressing daDREAM, reduced dendritic basal arborization and spine density in CA1 pyramidal neurons and increased spine density in dendrites in dentate gyrus granule cells. These microanatomical changes are accompanied by significant modifications in the expression of specific genes encoding the cytoskeletal proteins Arc, Formin 1 and Gelsolin in daDREAM hippocampus. Our results strongly suggest that DREAM plays an important role in structural plasticity in the hippocampus.

Script-like attachment representations in dreams containing current romantic partners.

Selterman, Dylan; Apetroaia, Adela; Waters, Everett

2012-01-01

Recent research has demonstrated parallels between romantic attachment styles and general dream content. The current study examined partner-specific attachment representations alongside dreams that contained significant others. The general prediction was that dreams would follow the "secure base script," and a general correspondence would emerge between secure attachment cognitions in waking life and in dreams. Sixty-one undergraduate student participants in committed dating relationships of six months duration or longer completed the Secure Base Script Narrative Assessment at Time 1, and then completed a dream diary for 14 consecutive days. Blind coders scored dreams that contained significant others using the same criteria for secure base content in laboratory narratives. Results revealed a significant association between relationship-specific attachment security and the degree to which dreams about romantic partners followed the secure base script. The findings illuminate our understanding of mental representations with regards to specific attachment figures. Implications for attachment theory and clinical applications are discussed.

Consciousness never fades during wake. However, if awakened from sleep, sometimes we report dreams and sometimes no experiences. Traditionally, dreaming has been identified with REM sleep, characterized by a wake-like, globally ‘activated’, high-frequency EEG. However, dreaming also occurs in NREM sleep, characterized by prominent low-frequency activity. This challenges our understanding of the neural correlates of conscious experiences in sleep. Using high-density EEG, we contrasted the presence and absence of dreaming within NREM and REM sleep. In both NREM and REM sleep, reports of dream experience were associated with a local decrease in low-frequency activity in posterior cortical regions. High-frequency activity within these regions correlated with specific dream contents. Monitoring this posterior ‘hot zone’ predicted whether an individual reported dreaming or the absence of experiences during NREM sleep in real time, suggesting that it may constitute a core correlate of conscious experiences in sleep.

Normal body scheme and absent phantom limb experience in amputees while dreaming.

2011-12-01

While dreaming amputees often experience a normal body image and the phantom limb may not be present. However, dreaming experiences in amputees have mainly been collected by questionnaires. We analysed the dream reports of amputated patients with phantom limb collected after awakening from REM sleep during overnight videopolysomnography (VPSG). Six amputated patients underwent overnight VPSG study. Patients were awakened during REM sleep and asked to report their dreams. Three patients were able to deliver an account of a dream. In all dreaming recalls, patients reported that the amputated limbs were intact and completely functional and they no longer experienced phantom limb sensations. Phantom limb experiences, that during wake result from a conflict between a pre-existing body scheme and the sensory information on the missing limb, were suppressed during sleep in our patients in favour of the image of an intact body accessed during dream.

Previous reports suggest that sex differences may exist in dreaming under anesthesia, but their results were inconclusive. The current study explored sex differences in the incidence and content of dreams during short propofol sedation for upper gastrointestinal endoscopy and investigated whether sex differences or dream content affect patient satisfaction with sedation. A total of 200 patients (100 men and 100 women) undergoing upper gastrointestinal endoscopy participated in this study. Patients were interviewed with the modified Brice questionnaire about the incidence and the content of dreams, and satisfaction with sedation was assessed. The results showed that the incidence of dreaming was significantly higher in men (31%) than in women (17%) (P=0.02), but recovery time was similar. In men, 45% (14/31) of dreamers reported positive emotional content and only 6% (2/31) reported negative emotional content. In contrast, in women, 18% (3/17) reported positive and 29% (5/17) reported negative content (P=0.04). Men reported dreams that were more vivid, meaningful, familiar, and memorable (P<0.01). No significant sex differences were observed in the emotional intensity of dreams, and emotional content did not influence patients' satisfaction. In sum, sex differences existed in dreaming during short propofol sedation despite similar recovery time and matching in terms of age. Men reported dreaming more frequently and had a higher incidence of recall for their dream narratives. In particular, men reported significantly more positive emotional content, less negative emotional content, and more meaningful content. Dreamer satisfaction with sedation was not influenced by sex or dream content.

The multiplicity of dreams: cognitive-affective correlates of lucid, archetypal, and nightmare dreaming.

This preliminary research is the first to compare lucid, nightmare, and archetypal-mythological dreams on dimensions important in previous research on each. A first study of 100 subjects showed all three forms significantly correlated with each other and with estimates of dream recall. In a second study, 41 subjects were selected from the above on the basis of relative specialization in each dream form, with a control group equally high on dream recall. Here, the lucid and archetypal dreamers tended to separate themselves from nightmare sufferers on the basis of high imaginativeness, proclivity to waking mystical experience, spatial/analytic skills, and physical balance. It appears that the intensification of dreaming is expressed positively or negatively, depending on variations in these cognitive dimensions.

The trophoblast transcription factor glial cell missing-1 (GCM1) regulates differentiation of placental cytotrophoblasts into the syncytiotrophoblast layer in contact with maternal blood. Reduced placental expression of GCM1 and abnormal syncytiotrophoblast structure are features of hypertensive disorder of pregnancy – preeclampsia. In-silico techniques identified the calcium-regulated transcriptional repressor – DREAM (Downstream Regulatory Element Antagonist Modulator) - as a candidate for GCM1 gene expression. Our objective was to determine if DREAM represses GCM1 regulated syncytiotrophoblast formation. EMSA and ChIP assays revealed a direct interaction between DREAM and the GCM1 promoter. siRNA-mediated DREAM silencing in cell culture and placental explant models significantly up-regulated GCM1 expression and reduced cytotrophoblast proliferation. DREAM calcium dependency was verified using ionomycin. Furthermore, the increased DREAM protein expression in preeclamptic placental villi was predominantly nuclear, coinciding with an overall increase in sumolylated DREAM and correlating inversely with GCM1 levels. In conclusion, our data reveal a calcium-regulated pathway whereby GCM1-directed villous trophoblast differentiation is repressed by DREAM. This pathway may be relevant to disease prevention via calcium-supplementation. PMID:23300953

Stability of cognition across wakefulness and dreams in psychotic major depression.

Cognitive bizarreness has been shown to be equally elevated in the dream and waking mentation of acutely symptomatic inpatients diagnosed with affective and non-affective psychoses. Although some studies have reported on dream content in non-psychotic depression, no study has previously measured this formal aspect of cognition in patients hospitalized for Psychotic Major Depression (PMD). Sixty-five dreams and 154 waking fantasy reports were collected from 11 PMD inpatients and 11 age- and sex-matched healthy controls. All narrative reports were scored by judges blind to diagnosis in terms of formal aspects of cognition (Bizarreness). Dream content was also scored (Hall/Van de Castle scoring system). Unlike controls, PMD patients had similar levels of cognitive bizarreness in their dream and waking mentation. Dreams of PMD patients also differed from those of controls in terms of content variables. In particular, Happiness, Apprehension and Dynamism were found to differ between the two groups. Whereas dream content reflects a sharp discontinuity with the depressive state, cognitive bizarreness adequately measures the stability of cognition across dreams and wakefulness in PMD inpatients.

Purpose To assess contrast sensitivity (CS) and to elucidate the factors associated with CS among subjects with type 2 diabetes in a cross-sectional population-based study. Patients and methods Subjects were recruited from a follow-up cohort, Sankara Nethralaya Diabetic Retinopathy Epidemiology and Molecular genetics Study (SN-DREAMS II). Of 958 subjects who were followed up in SN-DREAMS II, a subset of 653 subjects was included in the analysis. All subjects underwent a comprehensive eye examination, which included CS assessment using the Pelli–Robson chart. The cross-sectional association between CS and independent variables was assessed using stepwise linear regression analysis. A P-value of <0.05 was considered statistically significant. Results The mean age of the study sample was 58.7±9.41 (44–87) years. Mean CS of the study sample was 1.32±0.20 (range: 0–1.65) log units. CS was negatively and significantly correlated with age, duration of diabetes, hemoglobin level, vibration perception threshold (VPT) value, albuminuria, best corrected visual acuity (BCVA), refractive error, total error score (TEM) of FM 100 hue test, and mean retinal sensitivity. In multiple regression analysis, after adjusting for all the related factors, CS was significantly associated with BCVA (β=−0.575; P<0.001), VPT (β=−0.003; P=0.010), severity of cataract (β=−0.018; P=0.032), diabetic retinopathy (β=−0.016; P=0.019), and age (β=−0.002; P=0.029). These factors explained about 29.3% of the variation in CS. Conclusion Among the factors evaluated, differences in BCVA were associated with the largest predicted differences in CS. This association of CS with visual acuity highlights the important role of visual assessment in type 2 diabetes. PMID:27858934

What are the memory sources of dreaming?

PubMed

Nielsen, Tore A; Stenstrom, Philippe

2005-10-27

Investigators since Freud have appreciated that memories of the people, places, activities and emotions of daily life are reflected in dreams but are typically so fragmented that their predictability is nil. The mechanisms that translate such memories into dream images remain largely unknown. New research targeting relationships between dreaming, memory and the hippocampus is producing a new theory to explain how, why and when we dream of waking life events.

Subpersonalities with dreaming functions in a patient with multiple personalities.

PubMed

Salley, R D

1988-02-01

A case report of the hypnotherapy and unusual dream work of a patient with multiple personality disorder is described. Two of his 13 personalities claimed a dream production function. These personalities claimed the ability to organize and create dreams in order to communicate with the host personality. In the course of therapy, clinical data are described that tend to support this claim. The data of this case are then briefly applied to some current models of dream function. Some dream theories with an information-processing and reprogramming emphasis are particularly supported by this case material.

Psychoanalysis and the neurosciences: a topical debate on dreams.

PubMed

Mancia, M

1999-12-01

The author begins by pointing out that, whereas Freud first turned his attention to dreams in 1895, they became an object of neuroscientific interest only in the 1950s, after the discovery of rapid-eye-movement (REM) sleep and the observation that a subject woken in an REM phase could remember and narrate them. He discusses the various brain structures found by the neuroscientists to be implicated in dreaming and the associated hypotheses about their involvement in the processes of remembering dreams, their spatial construction and semantic organisation, and the dreamer's emotional participation in and narration of dreams. Attention is drawn to recent psychophysiological research findings indicating that dreaming occurs in all sleep phases and not only in REM episodes. The cognitivist contribution is also discussed. The author goes on to demonstrate the difference between the neuroscientific and psychoanalytic approaches to dreams. Whereas the neuroscientists are interested in the structures involved in dream production and in dream organisation and narratability, psychoanalysis concentrates on the meaning of dreams and on placing them in the context of the analytic relationship in accordance with the affective history of the dreamer and the transference. The brain structures and functions of interest to the neurosciences, while constituting the physical and biological substrate of these aspects, are stated to be irrelevant to their psychoanalytic understanding.

Although central to any exhaustive theory of human subjectivity, the relationship between dream and waking consciousness remains uncertain. Some findings suggest that dream consciousness can be influenced by severe disorders of thought content. The suppression of unwanted thoughts has been shown to influence dream content in healthy individuals. In order to better define this phenomenon, we evaluated the persistence of obsessive/compulsive themes across the dream and waking cognition of OCD patients and in a control group of healthy subjects. Participants were administered a shortened version of the Thematic Apperception Test to produce a waking fantasy narration, and were trained to keep a dream diary. Dream and waking narrative contents were analyzed in order to recognize obsessive/compulsive themes, and to calculate Mean Dream Obsession/Compulsion (MDO, MDC) and Mean TAT Obsession/Compulsion (MTO, MTC) parameters. No differences were found between the two populations in terms of MDO, MDC, MTO, nor MTC. Density of obsessive and compulsive themes were significantly higher in dream reports than in waking narratives for both groups. No correlation was observed between MDO/MDC scores and Y-BOCS obsession/compulsion scores in the OCD group. These findings strengthen the discontinuity hypothesis, suggesting that ruminative aspects of cognition are somehow interrupted during dream activity. Copyright © 2016 Elsevier Ireland Ltd.

Infrequent dream recall associated with low performance but high overnight improvement on mirror-tracing.

2015-08-01

Although sleep facilitates learning and memory, the roles of dreaming and habitual levels of recalling dreams remain unknown. This study examined if performance and overnight improvement on a rapid eye movement sleep-sensitive visuomotor task is associated differentially with habitually high or low dream recall frequency. As a relation between dream production and visuospatial skills has been demonstrated previously, one possibility is that frequency of dream recall will be linked to performance on visuomotor tasks such as the Mirror Tracing Task. We expected that habitually low dream recallers would perform more poorly on the Mirror Tracing Task than would high recallers and would show less task improvement following a night of sleep. Fifteen low and 20 high dream recallers slept one night each in the laboratory and performed the Mirror Tracing Task before and after sleep. Low recallers had overall worse baseline performance but a greater evening-to-morning improvement than did high recallers. Greater improvements in completion time in low recallers were associated with Stage 2 rather than rapid eye movement sleep. Findings support the separate notions that dreaming is related to visuomotor processes and that different levels of visuomotor skill engage different sleep- and dream-related consolidation mechanisms. © 2015 European Sleep Research Society.

Prior reports suggest that dreaming during anaesthesia is dependent on recovery time. Dreaming during sedation may impact patient satisfaction. The current study explores the incidence and content of dreaming during short-term sedation with sevoflurane or propofol and investigates whether dreaming is affected by recovery time. A total of 200 women undergoing first trimester abortion (American Society of Anesthesiologists physical status I) participated in the study. Patients were randomly assigned to receive either sevoflurane or propofol for short-term sedation. Patients were interviewed upon emergence with the modified Brice questionnaire. The results showed the incidence of dreaming was significantly different between anaesthesia groups with 60% (60/100) of the sevoflurane group and 33% (33/100) of the propofol group (P=0.000). However, recovery time did not significantly differ between groups. In the sevoflurane group, a greater number of dreamers could not recall what they had dreamed about (P=0.02) and more patients reported dreams that had no sound (P=0.03) or movement (P=0.001) compared with dreamers in the propofol group. Most participants reported dreams with positive emotional content and this did not significantly differ between groups. Anaesthesia administered had no effect on patient satisfaction. The results suggest that the incidence of dreaming was not affected by recovery time. Patient satisfaction was not influenced by choice of sedative and/or by the occurrence of dreaming during sevoflurane or propofol short-term sedation.

Resting brain activity varies with dream recall frequency between subjects.

Dreaming is still poorly understood. Notably, its cerebral underpinning remains unclear. Neuropsychological studies have shown that lesions in the temporoparietal junction (TPJ) and/or the white matter of the medial prefrontal cortex (MPFC) lead to the global cessation of dream reports, suggesting that these regions of the default mode network have key roles in the dreaming process (forebrain 'dream-on' hypothesis). To test this hypothesis, we measured regional cerebral blood flow (rCBF) using [(15)O]H2O positron emission tomography in healthy subjects with high and low dream recall frequencies (DRFs) during wakefulness (rest) and sleep (rapid eye movement (REM) sleep, N2, and N3). Compared with Low recallers (0.5 ± 0.3 dream recall per week in average), High recallers (5.2 ± 1.4) showed higher rCBF in the TPJ during REM sleep, N3, and wakefulness, and in the MPFC during REM sleep and wakefulness. We demonstrate that the resting states of High recallers and Low recallers differ during sleep and wakefulness. It coheres with previous ERP results and confirms that a high/low DRF is associated with a specific functional organization of the brain. These results support the forebrain 'dream-on' hypothesis and suggest that TPJ and MPFC are not only involved in dream recall during wakefulness but also have a role in dreaming during sleep (production and/or encoding). Increased activity in the TPJ and MPFC might promote the mental imagery and/or memory encoding of dreams. Notably, increased activity in TPJ might facilitate attention orienting toward external stimuli and promote intrasleep wakefulness, facilitating the encoding of the dreams in memory.

There is a lack of up-to-date data on sleep and dream habits of college students. To fill in this gap, we used an online questionnaire sent to the student mailing lists of two major universities of Lyon (Lyon 1 and Lyon 2) for the recruitment of an functional magnetic resonance imaging study with sleep disorders as exclusion criteria. In the sample (1,137 French college students, 411 males, mean age = 22.2 ± 2.4 years, body mass index = 22.0 ± 3.2 kg m -2 ), on average, the participants reported spending about 8 hr in bed during weekdays, 9 hr during the weekends, and 90.9% of them reported no difficulty falling asleep. Less than 0.4% of students reported to have sleep-walking episodes regularly, but nearly 7% reported regular sleep-talking episodes. The average dream recall frequency was about 3 mornings per week with a dream in mind. Dream recall frequency was positively correlated with the clarity of dream content and the frequency of lucid dreaming, and was negatively correlated with age. Fourteen percent of the students reported frequent lucid dreams, and 6% reported frequent recurrent dreams. We found a gender effect for several sleep and dream parameters, including dream recall frequency and time in bed, both of which were higher in women than in men. We have also observed differences between academic disciplines, namely humanities students (Lyon 2) reported spending more time in bed than sciences students (Lyon 1). These results confirm a gender difference for several sleep and dream parameters, and suggest a link between academic disciplines and sleep duration. © 2018 European Sleep Research Society.

The author, a psychoanalyst, discusses the 2010 film, Inception, discerning the parallels and differences between cinematic dreaming states as shown in the film and psychoanalytic processes. The movie presents the unknown and un-psychoanalytic phenomena of group shared dreaming, manipulation of other people's dreams with criminal intent, and multiple structured layers of dreaming. In parallel, however, the lead character appears to work through a complicated state of derealization, mourning, guilt, rage, and loss in the course of dreaming.

Previous validation studies of sick leave measures have focused on self-reports. Register-based sick leave data are considered to be valid; however methodological problems may be associated with such data. A Danish national register on sickness benefit (DREAM) has been widely used in sick leave research. On the basis of sick leave records from 3,554 and 2,311 eldercare workers in 14 different workplaces, the aim of this study was to: 1) validate registered sickness benefit data from DREAM against workplace-registered sick leave spells of at least 15 days; 2) validate self-reported sick leave days during one year against workplace-registered sick leave. Agreement between workplace-registered sick leave and DREAM-registered sickness benefit was reported as sensitivities, specificities and positive predictive values. A receiver-operating characteristic curve and a Bland-Altman plot were used to study the concordance with sick leave duration of the first spell. By means of an analysis of agreement between self-reported and workplace-registered sick leave sensitivity and specificity was calculated. Ninety-five percent confidence intervals (95% CI) were used. The probability that registered DREAM data on sickness benefit agrees with workplace-registered sick leave of at least 15 days was 96.7% (95% CI: 95.6-97.6). Specificity was close to 100% (95% CI: 98.3-100). The registered DREAM data on sickness benefit overestimated the duration of sick leave spells by an average of 1.4 (SD: 3.9) weeks. Separate analysis on pregnancy-related sick leave revealed a maximum sensitivity of 20% (95% CI: 4.3-48.1).The sensitivity of self-reporting at least one or at least 56 sick leave day/s was 94.5 (95% CI: 93.4 - 95.5) % and 58.5 (95% CI: 51.1 - 65.6) % respectively. The corresponding specificities were 85.3 (95% CI: 81.4 - 88.6) % and 98.9 (95% CI: 98.3 - 99.3) %. The DREAM register offered valid measures of sick leave spells of at least 15 days among eldercare employees. Pregnancy-related sick leave should be excluded in studies planning to use DREAM data on sickness benefit. Self-reported sick leave became more imprecise when number of absence days increased, but the sensitivity and specificity were acceptable for lengths not exceeding one week.

Evidence that non-dreamers do dream: a REM sleep behaviour disorder model.

To determine whether non-dreamers do not produce dreams or do not recall them, subjects were identified with no dream recall with dreamlike behaviours during rapid eye movement sleep behaviour disorder, which is typically characterised by dream-enacting behaviours congruent with sleep mentation. All consecutive patients with idiopathic rapid eye movement sleep behaviour disorder or rapid eye movement sleep behaviour disorder associated with Parkinson's disease who underwent a video-polysomnography were interviewed regarding the presence or absence of dream recall, retrospectively or upon spontaneous arousals. The patients with no dream recall for at least 10 years, and never-ever recallers were compared with dream recallers with rapid eye movement sleep behaviour disorder regarding their clinical, cognitive and sleep features. Of the 289 patients with rapid eye movement sleep behaviour disorder, eight (2.8%) patients had no dream recall, including four (1.4%) patients who had never ever recalled dreams, and four patients who had no dream recall for 10-56 years. All non-recallers exhibited, daily or almost nightly, several complex, scenic and dreamlike behaviours and speeches, which were also observed during rapid eye movement sleep on video-polysomnography (arguing, fighting and speaking). They did not recall a dream following sudden awakenings from rapid eye movement sleep. These eight non-recallers with rapid eye movement sleep behaviour disorder did not differ in terms of cognition, clinical, treatment or sleep measures from the 17 dreamers with rapid eye movement sleep behaviour disorder matched for age, sex and disease. The scenic dreamlike behaviours reported and observed during rapid eye movement sleep in the rare non-recallers with rapid eye movement sleep behaviour disorder (even in the never-ever recallers) provide strong evidence that non-recallers produce dreams, but do not recall them. Rapid eye movement sleep behaviour disorder provides a new model to evaluate cognitive processing during dreaming and subsequent recall. © 2015 European Sleep Research Society.

Yanto, Theo Audi; Kosasih, Felicia Nathania

2018-01-01

Background Metformin is widely known as an antidiabetic agent which has significant gastrointestinal side effects, but nightmares and abnormal dreams as its adverse reactions are not well reported. Case Presentation Herein we present a case of 56-year-old male patient with no known history of recurrent nightmares and sleep disorder, experiencing nightmare and abnormal dreams directly after consumption of 750 mg extended release metformin. He reported his dream as an unpleasant experience which awakened him at night with negative feelings. The nightmare only lasted for a night, but his dreams every night thereafter seemed abnormal. The dreams were vivid and indescribable. The disappearance and occurrence of abnormal dreams ensued soon after the drug was discontinued and rechallenged. The case was assessed using Naranjo Adverse Drug Reaction (ADR) probability scale and resulted as probable causality. Conclusion Metformin might be the underlying cause of nightmare and abnormal dreams in this patient. More studies are needed to confirm the association and causality of this findings. PMID:29581904

To test if dreams contain remote or never-experienced motor skills, we collected during 6 weeks dream reports from 15 paraplegics and 15 healthy subjects. In 9/10 subjects with spinal cord injury and in 5/5 with congenital paraplegia, voluntary leg movements were reported during dream, including feelings of walking (46%), running (8.6%), dancing (8%), standing up (6.3%), bicycling (6.3%), and practicing sports (skiing, playing basketball, swimming). Paraplegia patients experienced walking dreams (38.2%) just as often as controls (28.7%). There was no correlation between the frequency of walking dreams and the duration of paraplegia. In contrast, patients were rarely paraplegic in dreams. Subjects who had never walked or stopped walking 4-64 years prior to this study still experience walking in their dreams, suggesting that a cerebral walking program, either genetic or more probably developed via mirror neurons (activated when observing others performing an action) is reactivated during sleep.

Consciousness is a multifaceted concept; its different aspects vary across species, vigilance states, or health conditions. While basal aspects of consciousness like perceptions and emotions are present in many states and species, higher-order aspects like reflective or volitional capabilities seem to be most pronounced in awake humans. Here we assess the experience of volition across different states of consciousness: 10 frequent lucid dreamers rated different aspects of volition according to the Volitional Components Questionnaire for phases of normal dreaming, lucid dreaming, and wakefulness. Overall, experienced volition was comparable for lucid dreaming and wakefulness, and rated significantly higher for both states compared to non-lucid dreaming. However, three subscales showed specific differences across states of consciousness: planning ability was most pronounced during wakefulness, intention enactment most pronounced during lucid dreaming, and self-determination most pronounced during both wakefulness and lucid dreaming. Our data confirm the multifaceted nature of consciousness: different higher-order aspects of consciousness are differentially expressed across different conscious states. PMID:24427149

Converging Paradigms: A Reflection on Parallel Theoretical Developments in Psychoanalytic Metapsychology and Empirical Dream Research.

PubMed

Schmelowszky, Ágoston

2016-08-01

In the last decades one can perceive a striking parallelism between the shifting perspective of leading representatives of empirical dream research concerning their conceptualization of dreaming and the paradigm shift within clinically based psychoanalytic metapsychology with respect to its theory on the significance of dreaming. In metapsychology, dreaming becomes more and more a central metaphor of mental functioning in general. The theories of Klein, Bion, and Matte-Blanco can be considered as milestones of this paradigm shift. In empirical dream research, the competing theories of Hobson and of Solms respectively argued for and against the meaningfulness of the dream-work in the functioning of the mind. In the meantime, empirical data coming from various sources seemed to prove the significance of dream consciousness for the development and maintenance of adaptive waking consciousness. Metapsychological speculations and hypotheses based on empirical research data seem to point in the same direction, promising for contemporary psychoanalytic practice a more secure theoretical base. In this paper the author brings together these diverse theoretical developments and presents conclusions regarding psychoanalytic theory and technique, as well as proposing an outline of an empirical research plan for testing the specificity of psychoanalysis in developing dream formation.

Can healthy, young adults uncover personal details of unknown target individuals in their dreams?

PubMed

Smith, Carlyle

2013-01-01

We investigated the possibility that undergraduate college students could incubate dreams containing information about unknown target individuals with significant life problems. In Experiment 1, students provided two baseline dreams. They were then exposed to a photo of an individual and invited to dream about a health problem (unknown to them and the experimenter) of that individual and asked to provide two more dreams. From a class of 65 students, 12 dreamers volunteered dreams about the unknown target. In Experiment 2, 66 students were asked to dream about the life problems of a second individual, simply by looking at the photo (experimental group). Another 56 students were exposed to this same paradigm, but the photo that they examined was computer generated and the target individual was fictitious (control group). The dream elements were objectively scored with categories devised using the Hall-Van de Castle system as a model. Data were ordinal, and the nonparametric Wilcoxon signed rank test was used to examine preincubation (baseline) versus postincubation (photo examination and incubation) dream content in Experiment 1. In Experiment 2, a Z score for proportions was used to compare differences in frequency of devised categories between experimental and control groups. In Experiment 1, the comparison of postincubation dreams (all categories combined) was significant compared with the preincubation dreams (Z = 2.09, P = .036). The postincubation dreams reflected the health problem of the target. In Experiment 2, the proportion of scored categories in experimental and control groups were compared at the preincubation and postincubation conditions. The proportions of "Combined" (all categories) was very significantly larger at the postincubation condition (Z = 6.27, P < .00001). The groups did not differ at the preincubation condition (Z = -1.12, not significant). Individual postincubation condition comparisons of the experimental versus control groups revealed significant differences in three of the devised scoring categories, ranging from P < .002 to P < .05. There were no experimental versus control preincubation differences. The postincubation dreams of the experimental group were related to the problems of the target individual. Young, healthy adults are capable of dreaming details about the personal problems of an unknown individual simply by examining a picture of the target and then planning to dream about that individual's problems.

Psychoanalysts since Freud have largely neglected his important, paradigmatic ideas on the possibility of 'thought-transference' (telepathy) as an influence in mental life. A chance recording of two dreams which proved to coincide in some detail with distant reality events again suggests evidence in favour of the telepathy hypothesis. On interpretation, one of these dreams reveals even greater correspondence with the reality event and shows the mechanism of transformation of the repressed wish from latent dream content into manifest dream, utilizing a number of elements of the dream instigator, an apparently telepathically received day residue. Working with this material proceeded against very strong resistance, most evident in repeated forgetting of one or another bit of the clinical data. This has been the fate of ideas pertaining to the occult since Freud's first formulations, as is documented here by references to the early history of psychoanalysis. The issue now and for the future is whether psychoanalysis will continue to ignore the crucial question of validity in regard to the telepathy hypothesis. The psychoanalytic method is uniquely qualified to investigate so-called parapsychological phenomena and has the same obligation to do so as with other mental events. We need to examine the evidence in spite of the threat posed to our conventional understanding of the limits of the mind by the very act of acknowledging the question. If we can overcome our resistance to undertaking this task, we may find that, once again, Freud pointed the way towards discovery of a new paradigm in science.

Abstract The aim of this study is to assess the cost-effectiveness of a holistic, comprehensive human immunodeficiency virus (HIV) treatment Program in Malawi. Comprehensive cost data for the year 2010 have been collected at 30 facilities from the public network of health centers providing antiretroviral treatment (ART) throughout the country; two of these facilities were operated by the Disease Relief through Excellent and Advanced Means (DREAM) program. The outcomes analysis was carried out over five years comparing two cohorts of patients on treatment: 1) 2387 patients who started ART in the two DREAM centers during 2008, 2) patients who started ART in Malawi in the same year under the Ministry of Health program. Assuming the 2010 cost as constant over the five years the cost-effective analysis was undertaken from a health sector and national perspective; a sensitivity analysis included two hypothesis of ART impact on patients’ income. The total cost per patient per year (PPPY) was $314.5 for the DREAM protocol and $188.8 for the other Malawi ART sites, with 737 disability adjusted life years (DALY) saved among the DREAM program patients compared with the others. The Incremental Cost-Effectiveness Ratio was $1640 per DALY saved; it ranged between $896–1268 for national and health sector perspective respectively. The cost per DALY saved remained under $2154 that is the AFR-E-WHO regional gross domestic product per capita threshold for a program to be considered very cost-effective. HIV/acquired immune deficiency syndrome comprehensive treatment program that joins ART with laboratory monitoring, treatment adherence reinforcing and Malnutrition control can be very cost-effective in the sub-Saharan African setting.

Numerous medicines in South Asia have their origins in dreams. Deities, saints and other supernatural beings frequently appear in dreams to instruct dreamers about specific remedies, therapeutic techniques, modes of care etc. These therapies challenge available models of historicising dreams. Once we overcome these challenges and unearth the embedded logic of these dreams, we begin to discern in them a dynamic institution that enabled and sustained therapeutic change within a 'traditional' medical milieu.

A phenomenology of dreams searches for meaning, with the aim not only of explaining but also of understanding the experience. What and who is it for? And what about the nearly forgotten dream among the moderns, the banal returning to the nightmare, sleepiness, or dreamlike reverie. Nostalgia for the dream, where we saw a very early state of light, not a ordinaire qu duel. Regret for the dreamlike splendor exceeded by the modeling power of modern aesthetics--film and the explosion of virtual imaging technologies. Disappointment at the discovery of a cognitive permanence throughout sleep and a unique fit with the real upon awaking? An excess of methodological rigor where we validate the logic of the dream, correlating the clinical improvement in psychotherapy and the ability to interpret one's own dreams. The dangerous psychological access when the dream primarily is mine, viewed as a veiled expression of an unspoken desire, or when the dream reveals to me, in an existential conception of man, through time and space, my daily life, my freedom beyond my needs. Might its ultimate sense also mean its abolition? From the story of a famous forgotten dream, based on unexpected scientific data emerges the question: do we dream to forget? The main thing would not be consciousness but confidence, when " the sleeping man, his regard extinguished, dead to himself seizes the light in the night " (Heraclitus).

In this article, dreams are seen as stories within a self-narrative. Dream stories, like all other stories, are told in an effort to make sense of experiences. Here, dream content is linked to current concerns, some aspects of which are not given voice in waking. Dreams depict restricting themes but also openings in self-narratives. Several examples are provided of how dreams can be linked to early, middle, and late therapy phases associated with recognizing, challenging, revising, and maintaining a revising stance. It is further suggested that dream stories can be used to trace, facilitate, and evaluate the process of reconstructing self-narratives. Finally, a number of therapeutic interventions are briefly presented to facilitate the work of narrative-informed family therapists working with individuals, families, and groups. © 2011 American Association for Marriage and Family Therapy.

Dreaming as a primordial state of the mind: the clinical relevance of structural faults in the body ego as revealed in dreaming.

PubMed

Andrade, Victor Manoel

2007-02-01

The therapeutic action of psychoanalysis, attributed for many years to the interpretation of the repressed libido, has shifted its focus to object relationships. Some modern analysts maintain that the primary factor of psychic change is the new model of object relationship provided by analysis, and do not consider significant the knowledge of episodes comprising implicit memories, whose irrecoverable nature is demonstrated by neuroscience. Nevertheless, the author proposes that the knowledge of specific archaic events, useless as their interpretation may be, offers a glimpse of the make-up of the mind, contributing to the improvement of the empathy indispensable for inducing changes in the patient. Episodes linked to absolute narcissism, in the beginnings of the body ego, which do not appear either in associations or in transference, emerge in dreams. Neuroscience has made possible the understanding of aspects of dreaming capable of providing a glimpse of the genesis of the ego, whose development from the bodily phase of absolute narcissism to the psychic object phase can thus be traced. The unearthing of the genesis of primary structural faults in dreaming furnishes the analyst with an estimate of the possibilities for development of the ego, and this knowledge provides fine tuning capable of guiding the analyst's conduct. A clinical case illustrates how these phenomena occur, showing the intersubjective relationship as the silent primary generator of psychic changes, consolidated and developed secondarily by means of the analytical dialogue.

Mapping gene expression as a quantitative trait using whole genome-sequencing and transcriptome analysis allows to discover the functional consequences of genetic variation. We developed a novel method and ultra-fast software Findr for higly accurate causal inference between gene expression traits using cis-regulatory DNA variations as causal anchors, which improves current methods by taking into consideration hidden confounders and weak regulations. Findr outperformed existing methods on the DREAM5 Systems Genetics challenge and on the prediction of microRNA and transcription factor targets in human lymphoblastoid cells, while being nearly a million times faster.

Objective: In this study, we examined the euphoric effect of propofol and its high satisfaction ratio regarding its liability to be abused, particularly in painless procedures, such as colonoscopy. Methods: Fifty subjects aged between 18 and 65 years who fulfilled the criteria for ASA 1-2 and were prepared for colonoscopy were enrolled into this study. For intravenous sedation induction, 2 mg/kg propofol was used, and additional injections were administered according to BIS values. After colonoscopy, the subjects were taken to a recovery room and observed for 30 minutes. Patients were interviewed with the modified Brice questionnare regarding the incidence and the content of dreams. A 5-point Likert scale was used to classify their dreams, and the content of the dreams was also recorded. To assess the subjective effects of propofol, the patients were asked to use the Hall and Van der Castle emotion scale; their biological states were also assessed. The patients’ feelings regarding propofol were each rated as absent or present. We used the Morphine-Benzedrine Group scale to measure the euphoric effects of propofol. At the end of the study, subjects scored their satisfaction on a five-point scale. Results: There were no statistically significant differences in sex age, weight, propofol dose, or satisfaction ratio (p>0.05) in the groups, although male patients received a higher dose of propofol and had higher satisfaction ratio. Patients reported no residual after-effects. The incidence of dreaming was 42%. There was no statistically significant difference in dreaming between the sexes, but male patients had a higher dreaming ratio. Dreamers received higher propofol doses and had a higher satisfaction ratio (p>0.05). All dreamers reported happy dreams regarding daily life, and their mean MBG score was 10.5. There was no correlation between MBG scores and propofol doses (r= -0.044, p= 0.761). Conclusions: We conclude that propofol functions as a reward; that patients enjoy its acute effects; and that no residual after-effects should arise. We suggest that propofol may carry potential for abuse, and further abuse liability testing is indicated. PMID:25674117

The Hydrometeorological DREAM: A Daily REcharge Assessment Model, for the Israeli Western Mountain Aquifer

NASA Astrophysics Data System (ADS)

Sheffer, N. A.; Dafny, E.; Gvirtzman, H.; Frumkin, A.; Navon, S.; Morin, E.

2008-05-01

The western part of the Israeli Mountain Aquifer (WMA) supplies 360-400 MCM/y of fresh water to the Israeli water budget, which is approximately 20% of the total consumption. The annually recharge to the WMA is considered to be 25-35% of annual rainfall. The high variability in recharge to the WMA is due to spatial and temporal differences in the rain contributing to the aquifer. Different winters producing the same amount of rain may contribute differently to the aquifer due to the locations of the storms, intensity, duration, dry spells between successive rain events, etc. Moreover, besides the climatic-meteorological factors, the recharge is dependent also on geographical factors, such as lithology, pedology, land-use, slope gradient, slope direction etc. The need for a robust reliable Hydrometeorological Daily basis REcharge Assessment Model (Hydrometeorological DREAM) brought us to develop a model with a relatively high spatial and temporal resolution. The concept is based on a relatively simple water budget that states that rainfall over land is added to the soil, and removed later on by means of evapotranspiration, recharge and runoff. The method in use to date at the Hydrological Service for estimating recharge to the WMA is based on an annual regression curve that can be implemented only after the total annual rainfall is known. The DREAM is a near real time estimator of recharge to the WMA using daily rainfall and pan evaporation data. Comparison of the DREAM results with the annual regression curve show a high agreement on an annual basis. The improvements introduced by the DREAM are: 1) Near real time daily values of infiltration, as opposed to calculated annual values established after the rain season is over. 2) High spatial resolution. The DREAM produces daily recharge values in more than 3000 mesh points throughout the 2200 km2 of recharge area. By linking the DREAM output as input to a hydrogeological model (such as FEFLOW, MODFLOW etc.) a completion of the water cycle can by achieved.

The 'mad scientists': psychoanalysis, dream and virtual reality.

PubMed

Leclaire, Marie

2003-04-01

The author explores the concept of reality-testing as a means of assessing the relationship with reality that prevails in dream and in virtual reality. Based on a model developed by Jean Laplanche, she compares these activities in detail in order to determine their respective independence from the function of reality-testing. By carefully examining the concept of hallucination in the writings of Freud and Daniel Dennett, the author seeks to pinpoint the specific modalities of interaction between perceptions, ideas, wishes and actions that converge in the 'belief' and in the 'sense of reality'. The paper's main thesis consists of the distinction that it draws between immediacy-testing and reality-testing, with the further argument that this distinction not only dissipates the conceptual vagueness that generally surrounds the latter of the two concepts but also that it promotes a more precise analysis of the function of reality in dream and in virtual reality.

On the Asclepian spirit and the future of psychoanalysis.

PubMed

Whitehead, Clay C

2002-01-01

The dynamics of the Asclepian myth are analyzed, and generic dynamics of the healing imperative are illustrated. The story teaches much about the early theories and practice of ancient medicine, and originated the healing symbol of the staff and serpent which appears on the emblem of the American Academy. The multi-modal therapeutic approach used at the Asclepia was often climaxed by dream incubation as a centerpiece of the treatment. Dreams from modern physicians in analysis will be introduced to show that while our practice has changed in external trappings, the underlying dynamics of ancient and modern healers reflect a common humanity. Modern therapists have reacquired the use of dreams and invented a new set of explanatory myths. Consideration of future developments leads to linking the "psychosomatic model" of antiquity with the psychopharmacological interventions which are now common-place in psychodynamic psychotherapy. The Asclepian emphasis on spirituality is also finding increasing recognition among psychoanalysts and other scientists.

Completion of a survey of dermatoglyphic variables for all ethnic groups in an ethnically diverse country like China is a huge research project, and an achievement that anthropological and dermatoglyphic scholars in the country could once only dream of. However, through the endeavors of scientists in China over the last 30 years, the dream has become reality. This paper reports the results of a comprehensive analysis of dermatoglyphics from all ethnic groups in China. Using cluster analysis and principal component analysis of dermatoglyphics, it has been found that Chinese populations can be generally divided into a southern group and a northern group. Furthermore, there has been considerable debate about the origins of many Chinese populations and about proper assignment of these peoples to larger ethnic groups. In this paper, we suggest that dermatoglyphic data can inform these debates by helping to classify a Chinese population as a northern or southern group, using selected reference populations and quantitative methods. This study is the first to assemble and investigate dermatoglyphics from all 56 Chinese ethnic groups. It is fortunate that data on population dermatoglyphics, a field of physical anthropology, have now been collected for all 56 Chinese ethnic groups, because intermarriage between individuals from different Chinese ethnic groups occurs more frequently in recent times, making population dermatoglyphic research an ever more challenging field of inquiry.

Reduced dream-recall frequency in left-handed adolescents: a replication.

2014-01-01

The ability to recall a dream upon waking up in the morning has been linked to a broad variety of factors such as personality, creativity, sleep behaviour and cognitive function. There have been conflicting findings as to whether dream recall is related more to the right or to the left hemisphere, and conflicting findings regarding the relationship of dream-recall frequency to handedness. We have found previously that right- and mixed-handers report having more dreams than left-handers, a finding more pronounced among adolescents than adults. In the present sample of 3535 participants aged from 6 to 18 years, right-handedness and mixed/inconsistent handedness were associated with higher dream-recall frequency compared to that of left-handed persons, again especially in adolescents compared with children. Further research is required to uncover the reason for the lower frequency of dream recall by left-handers.

Lucid Dreaming and Ventromedial versus Dorsolateral Prefrontal Task Performance

Neider, Michelle; Pace-Schott, Edward F.; Forselius, Erica; Pittman, Brian; Morgan, Peter T.

2010-01-01

Activity in the prefrontal cortex may distinguish the meta-awareness experienced during lucid dreams from its absence in normal dreams. To examine a possible relationship between dream lucidity and prefrontal task performance, we carried out a prospective study in 28 high school students. Participants performed the Wisconsin Card Sort and Iowa Gambling tasks, then for one week kept dream journals and reported sleep quality and lucidity-related dream characteristics. Participants who exhibited a greater degree of lucidity performed significantly better on the task that engages the ventromedial prefrontal cortex (the Iowa Gambling Task), but degree of lucidity achieved did not distinguish performance on the task that engages the dorsolateral prefrontal cortex (the Wisconsin Card Sort Task), nor did it distinguish self-reported sleep quality or baseline characteristics. The association between performance on the Iowa Gambling Task and lucidity suggests a connection between lucid dreaming and ventromedial prefrontal function. PMID:20829072

The Psychotomimetic Nature of Dreams: An Experimental Study

PubMed Central

Mason, Oliver; Wakerley, Dominic

2012-01-01

Several theories promote the similarities between dreaming and psychosis, but this has rarely been tested empirically. We assessed dreaming and waking reality using the Psychotomimetic States Inventory, a measure of psychotic-like experience originally designed for drug studies. Twenty participants completed the measure in each of two dream conditions and one waking condition. Dreams were assessed upon waking naturally and also using a movement-activated (actigraph) alarm during the night. Overall, participants reported more quasipsychotic characteristics during dreams (in both conditions) than when awake. This was most marked for paranoia and delusional thinking, but differences were also seen for perceptual abnormalities, mania, and anhedonia. The quality of dream experience seems particularly similar to psychosis in sometimes being highly self-referential and having a paranoid content. Subjective changes to cognition and affect are consistent with alterations in prefrontal cortical activity during REM sleep that mirror those of schizophrenia. PMID:22966450

The Knowledge Society: Refounding the Socius

NASA Astrophysics Data System (ADS)

de Beer, Carel S.

The theme 'knowledge society' can have many meanings depending on who defines it. But can knowledge really define society since there are many other qualifying adjectives for society as well. What one should be preferred? Is knowledge a better qualifying term than risk, information, technology, or any other one? These questions need answers. There are many dreams and counter dreams regarding the ideal society. Some dreams, like Unesco's dream, focus on the self-evident issues in the knowledge society, or what people consider to be self-evident, or what is taken for granted, as if no exploration is required: issues like access to knowledge, knowledge management, knowledge sharing, etc. These dreams contain a threat despite promises of a future that cannot be achieved. Other dreams, like those of Ars Industrialis, dig deeper and look for founding possibilities, take nothing for granted, search for the original, the defining principles. These dreams bring hope and light, a future to live for.

Sexual dreams reflect the waking-day life, social problems and ethical concerns. The related experience includes different people and settings, and brings various feelings, but there is no systematic measure available to date. We have developed a statement-matrix measuring the sexual dream experience and trialed it in a sample of 390 young Chinese university students who had a life-long sexual dream. After both exploratory and confirmatory factor analyses, we have established a satisfactory model of four-factor (32 items). Together with an item measuring the sexual dream frequency, we developed a Sexual Dream Experience Questionnaire (SDEQ) based on the 32 items, and subsequently named four factors (scales) as joyfulness, aversion, familiarity and bizarreness. No gender differences were found on the four scale scores, and no correlations were found between the four scales and the sexual dream frequency or the sexual experience in real life. The SDEQ might help to characterize the sexual dreams in the healthy people and psychiatric patients. Copyright © 2014 Elsevier Inc. All rights reserved.

Propofol dose and incidence of dreaming during sedation.

Dreaming is commonly reported after propofol-based sedation. We measured the incidence of dreaming and bispectral index (BIS) values in colonoscopy patients sedated with combinations of propofol, midazolam and fentanyl. Two hundred patients presenting for elective outpatient colonoscopy were sedated with combinations of propofol, midazolam and fentanyl. BIS was monitored throughout the procedure. Patients were interviewed immediately after they emerged from sedation. The primary end point was a report of dreaming during sedation. Ninety-seven patients were administered propofol alone, 44 were administered propofol and fentanyl, 16 were administered propofol and midazolam and 43 were administered propofol, midazolam and fentanyl. Dreaming was reported by 19% of patients. Dreamers received higher doses of propofol and had lower BIS values during sedation. Age of 50 years or less, preoperative quality of recovery score of less than 14, higher home dream recall, propofol dose of more than 300 mg and time to Observers' Assessment of Alertness/Sedation score equalling 5 of 8 min or less were independent predictors of dreaming. Dreaming during sedation is associated with higher propofol dose and lower BIS values.

Free Energy and Virtual Reality in Neuroscience and Psychoanalysis: A Complexity Theory of Dreaming and Mental Disorder.

PubMed

Hopkins, Jim

2016-01-01

The main concepts of the free energy (FE) neuroscience developed by Karl Friston and colleagues parallel those of Freud's Project for a Scientific Psychology. In Hobson et al. (2014) these include an innate virtual reality generator that produces the fictive prior beliefs that Freud described as the primary process. This enables Friston's account to encompass a unified treatment-a complexity theory-of the role of virtual reality in both dreaming and mental disorder. In both accounts the brain operates to minimize FE aroused by sensory impingements-including interoceptive impingements that report compliance with biological imperatives-and constructs a representation/model of the causes of impingement that enables this minimization. In Friston's account (variational) FE equals complexity minus accuracy, and is minimized by increasing accuracy and decreasing complexity. Roughly the brain (or model) increases accuracy together with complexity in waking. This is mediated by consciousness-creating active inference-by which it explains sensory impingements in terms of perceptual experiences of their causes. In sleep it reduces complexity by processes that include both synaptic pruning and consciousness/virtual reality/dreaming in REM. The consciousness-creating active inference that effects complexity-reduction in REM dreaming must operate on FE-arousing data distinct from sensory impingement. The most relevant source is remembered arousals of emotion, both recent and remote, as processed in SWS and REM on "active systems" accounts of memory consolidation/reconsolidation. Freud describes these remembered arousals as condensed in the dreamwork for use in the conscious contents of dreams, and similar condensation can be seen in symptoms. Complexity partly reflects emotional conflict and trauma. This indicates that dreams and symptoms are both produced to reduce complexity in the form of potentially adverse (traumatic or conflicting) arousals of amygdala-related emotions. Mental disorder is thus caused by computational complexity together with mechanisms like synaptic pruning that have evolved for complexity-reduction; and important features of disorder can be understood in these terms. Details of the consilience among Freudian, systems consolidation, and complexity-reduction accounts appear clearly in the analysis of a single fragment of a dream, indicating also how complexity reduction proceeds by a process resembling Bayesian model selection.

Freud, Bion and Kant: Epistemology and anthropology in The Interpretation of Dreams.

PubMed

Sandford, Stella

2017-02-01

This interdisciplinary article takes a philosophical approach to The Interpretation of Dreams, connecting Freud to one of the few philosophers with whom he sometimes identified - Immanuel Kant. It aims to show that Freud's theory of dreams has more in common with Bion's later thoughts on dreaming than is usually recognized. Distinguishing, via a discussion of Kant, between the conflicting 'epistemological' and 'anthropological' aspects of The Interpretation of Dreams, it shows that one specific contradiction in the book - concerning the relation between dream-work and waking thought - can be understood in terms of the tension between these conflicting aspects. Freud reaches the explicit conclusion that the dream-work and waking thought differ from each other absolutely; but the implicit conclusion of The Interpretation of Dreams is quite the opposite. This article argues that the explicit conclusion is the result of the epistemological aspects of the book; the implicit conclusion, which brings Freud much closer to Bion, the result of the anthropological approach. Bringing philosophy and psychoanalysis together this paper thus argues for an interpretation of The Interpretation of Dreams that is in some ways at odds with the standard view of the book, while also suggesting that aspects of Kant's 'anthropological' works might legitimately be seen as a precursor of psychoanalysis.

Dreams as a source of supernatural agent concepts.

PubMed

McNamara, Patrick; Bulkeley, Kelly

2015-01-01

We present a theory of the creativity of dreams as well as psychopathology of religious delusions with respect to production of fundamental forms of religious cognition-specifically supernatural agent (SA) cognitions. We suggest that dream cognitions are particularly efficient at producing highly memorable and impactful experiences with SAs because dreams involve three processes that are prerequisites for the generation of god concepts: (1) mental simulations of alternative realities, (2) theory of mind attributions to the extra-natural dream characters and divine beings, and (3) attribution of ultimate value (exemplified by 'good spirit beings'), and dis-value (exemplified by demonic monsters) to the supernatural dream characters. Because prefrontal cortex is deactivated during rapid eye movements (REM) sleep agentic impulses and internally generated ideas are not reliably attributed to Self or dreamer. Instead an exaggerated degree of agency is attributed to these supernatural dream characters who are then embedded in stories in dreams and in myths of waking life which explain their supernatural abilities. These dream-based SAs are salient characters that are processed in sleep-related memory systems according to rules of Lleweelyn's ancient art of memory model and therefore more easily remembered and reflected upon during waking life. When REM sleep intrudes into waking consciousness, as is the case with some forms of schizophrenia, religious delusions are more likely to emerge.

Are delusional contents replayed during dreams?

2013-09-01

The relationship between dream content and waking life experiences remains difficult to decipher. However, some neurobiological findings suggest that dreaming can, at least in part, be considered epiphenomenal to ongoing memory consolidation processes in sleep. Both abnormalities in sleep architecture and impairment in memory consolidation mechanisms are thought to be involved in the development of psychosis. The objective of this study was to assess the continuity between delusional contents and dreams in acutely psychotic patients. Ten patients with a single fixed and recurring delusional content were asked to report their dreams during an acute psychotic break. Sixteen judges with four different levels of acquaintance to the specific content of the patients' delusions were asked to group the dreams, expecting that fragments of the delusional thought would guide the task. A mathematical index (f,t) was developed in order to compare correct groupings between the four groups of judges. Most judges grouped the dreams slightly above chance level and no relevant differences could be found between the four groups [F(3,12)=1.297; p=n.s.]. Scoring of dreams for specific delusional themes suggested a continuity in terms of dream and waking mentation for two contents (Grandiosity and Religion). These findings seem to suggest that at least some delusional contents recur within patients' dreams. Future studies will need to determine whether such continuity reflects ongoing consolidation processes that are relevant to current theories of delusion formation and stabilization.

We aimed to assess dream content in groups of congenitally blind (CB), late blind (LB), and age- and sex-matched sighted control (SC) participants. We conducted an observational study of 11 CB, 14 LB, and 25 SC participants and collected dream reports over a 4-week period. Every morning participants filled in a questionnaire related to the sensory construction of the dream, its emotional and thematic content, and the possible occurrence of nightmares. We also assessed participants' ability of visual imagery during waking cognition, sleep quality, and depression and anxiety levels. All blind participants had fewer visual dream impressions compared to SC participants. In LB participants, duration of blindness was negatively correlated with duration, clarity, and color content of visual dream impressions. CB participants reported more auditory, tactile, gustatory, and olfactory dream components compared to SC participants. In contrast, LB participants only reported more tactile dream impressions. Blind and SC participants did not differ with respect to emotional and thematic dream content. However, CB participants reported more aggressive interactions and more nightmares compared to the other two groups. Our data show that blindness considerably alters the sensory composition of dreams and that onset and duration of blindness plays an important role. The increased occurrence of nightmares in CB participants may be related to a higher number of threatening experiences in daily life in this group. Copyright © 2014 Elsevier B.V.

Divination, prognosis and prophylaxis: the Hippocratic work 'on dreams' (De victu 4) and its Near Eastern background.

PubMed

van der Eijk, P J

2004-01-01

Building on the results of recent scholarship concerning the coherence of the Hippocratic work De victu ('On Regimen'), this chapter discusses the close connections between Book 4, which deals with the use of dreams for medical prognosis and especially prophylaxis (which the author claims to be his own innovation), with the rest of the work. It analyses the author's position on dreams and their interpretation and his stance against professional dream interpreters. It distinguishes five categories in the author's discussion: 1. the signs, i.e. the dream images themselves; 2. the significance of the dreams; 3. explanations of the relationship between sign and significance; 4. prophylactic (dietetic) measures to prevent disease; 5. instructions as to the gods one should pray to in order to prevent disease. It explores the rationale underlying these categories and lists a number of parallels with Babylonian dream literature. It concludes that although there are important differences with respect to the use of dreams in Babylonian medicine, it is not implausible that the author of De victu 4 has borrowed some of his material from Near Eastern dream books. At the same time, the author of De victu 4 distances himself from oneiromantic practices that are very similar to what we find in Babylonia; and his elaborate interpretative system linking specific dreams to specific bodily disorders goes far beyond anything found in Near Eastern sources (but also beyond anything else in the Corpus Hippocraticum). He does accept the existence of dreams sent by the gods and of prayer to the gods in combination with dietetic prophylaxis; but his elaborate use of dietetics for preventive purposes marks an important innovation when compared to Babylonian medicine. The author is not concerned with incubation.

Dreaming under antidepressants: a systematic review on evidence in depressive patients and healthy volunteers.

Sleep related symptoms of depression include sleep fragmentation, early morning awakening, decreased rapid eye movement (REM) sleep latency, increased REM density, and more negative dream content. Most tricyclic antidepressants (ADs) increase total sleep time and decrease wake time after sleep onset, while many selective serotonin reuptake inhibitors (SSRIs) have an opposite effect. However, almost all ADs prolong REM sleep latency and reduce the amount of REM sleep. Case reports and research data indicate a strong effect of ADs on dream recall and dream content. We performed a systematic review (1950 to August 2010) about ADs impact on dreaming in depressive patients and healthy volunteers. Twenty-one clinical studies and 25 case reports were eligible for review and document a clear AD effect on dreaming. The major finding, both in depressed patients and in healthy volunteers, is a decrease of dream recall frequency (DRF) under ADs. This is a rather consistent effect in tricyclic ADs and phenelzine, less consistently documented also for SSRIs/serotonin norepinephrine reuptake inhibitors (SNRIs). Tricyclic ADs induce more positive dream emotions. Withdrawal from tricyclic ADs and from the monoamine oxidase inhibitors phenelzine and tranylcypromine may cause nightmares. Intake and even more withdrawal of SSRIs/SNRIs seem to intensify dreaming, which may be experienced in different ways; a potential to cause nightmares has to be taken into account. Though there are clear-cut pharmacological effects of ADs on DRF and dream content, publications have been surprisingly scarce during the past 60 years. There is evidence of a gap in neuropsychopharmacological research. AD effects on dreams should be recognized and may be used in treatment. Copyright © 2012 Elsevier Ltd. All rights reserved.

Dream characteristics in a Brazilian sample: an online survey focusing on lucid dreaming

During sleep, humans experience the offline images and sensations that we call dreams, which are typically emotional and lacking in rational judgment of their bizarreness. However, during lucid dreaming (LD), subjects know that they are dreaming, and may control oneiric content. Dreaming and LD features have been studied in North Americans, Europeans and Asians, but not among Brazilians, the largest population in Latin America. Here we investigated dreams and LD characteristics in a Brazilian sample (n = 3,427; median age = 25 years) through an online survey. The subjects reported recalling dreams at least once a week (76%), and that dreams typically depicted actions (93%), known people (92%), sounds/voices (78%), and colored images (76%). The oneiric content was associated with plans for the upcoming days (37%), memories of the previous day (13%), or unrelated to the dreamer (30%). Nightmares usually depicted anxiety/fear (65%), being stalked (48%), or other unpleasant sensations (47%). These data corroborate Freudian notion of day residue in dreams, and suggest that dreams and nightmares are simulations of life situations that are related to our psychobiological integrity. Regarding LD, we observed that 77% of the subjects experienced LD at least once in life (44% up to 10 episodes ever), and for 48% LD subjectively lasted less than 1 min. LD frequency correlated weakly with dream recall frequency (r = 0.20, p < 0.01), and LD control was rare (29%). LD occurrence was facilitated when subjects did not need to wake up early (38%), a situation that increases rapid eye movement sleep (REMS) duration, or when subjects were under stress (30%), which increases REMS transitions into waking. These results indicate that LD is relatively ubiquitous but rare, unstable, difficult to control, and facilitated by increases in REMS duration and transitions to wake state. Together with LD incidence in USA, Europe and Asia, our data from Latin America strengthen the notion that LD is a general phenomenon of the human species. PMID:24368900

Inference of Gene Regulatory Networks Using Bayesian Nonparametric Regression and Topology Information.

PubMed

Fan, Yue; Wang, Xiao; Peng, Qinke

2017-01-01

Gene regulatory networks (GRNs) play an important role in cellular systems and are important for understanding biological processes. Many algorithms have been developed to infer the GRNs. However, most algorithms only pay attention to the gene expression data but do not consider the topology information in their inference process, while incorporating this information can partially compensate for the lack of reliable expression data. Here we develop a Bayesian group lasso with spike and slab priors to perform gene selection and estimation for nonparametric models. B-spline basis functions are used to capture the nonlinear relationships flexibly and penalties are used to avoid overfitting. Further, we incorporate the topology information into the Bayesian method as a prior. We present the application of our method on DREAM3 and DREAM4 datasets and two real biological datasets. The results show that our method performs better than existing methods and the topology information prior can improve the result.

DREAMing: a simple and ultrasensitive method for assessing intratumor epigenetic heterogeneity directly from liquid biopsies

Many cancers comprise heterogeneous populations of cells at primary and metastatic sites throughout the body. The presence or emergence of distinct subclones with drug-resistant genetic and epigenetic phenotypes within these populations can greatly complicate therapeutic intervention. Liquid biopsies of peripheral blood from cancer patients have been suggested as an ideal means of sampling intratumor genetic and epigenetic heterogeneity for diagnostics, monitoring and therapeutic guidance. However, current molecular diagnostic and sequencing methods are not well suited to the routine assessment of epigenetic heterogeneity in difficult samples such as liquid biopsies that contain intrinsically low fractional concentrations of circulating tumor DNA (ctDNA) and rare epigenetic subclonal populations. Here we report an alternative approach, deemed DREAMing (Discrimination of Rare EpiAlleles by Melt), which uses semi-limiting dilution and precise melt curve analysis to distinguish and enumerate individual copies of epiallelic species at single-CpG-site resolution in fractions as low as 0.005%, providing facile and inexpensive ultrasensitive assessment of locus-specific epigenetic heterogeneity directly from liquid biopsies. The technique is demonstrated here for the evaluation of epigenetic heterogeneity at p14ARF and BRCA1 gene-promoter loci in liquid biopsies obtained from patients in association with non-small cell lung cancer (NSCLC) and myelodysplastic/myeloproliferative neoplasms (MDS/MPN), respectively.

Dreaming as inspiration evidence from religion, philosophy, literature, and film.

Bulkeley, Kelly

2010-01-01

This paper presents evidence from the history of religion, philosophy, literature, and film to suggest that dreaming is a primal wellspring of creative inspiration. Powerful, reality-bending dreams have motivated the cultural creativity of people all over the world and throughout history. Examples include the dream revelations of Egyptian Pharaohs, the philosophical insights of Socrates, the dark literary themes of Fyodor Dostoevsky, and the cinematic artistry of Akira Kurusawa. Although the conclusions that can be drawn from these sources are limited by several methodological factors, the evidence gives contemporary researchers good reasons to explore the creative potentials of dreaming and the impact on waking life behavior of certain types of extraordinary dream experience.

Hinton, Devon E; Field, Nigel P; Nickerson, Angela; Bryant, Richard A; Simon, Naomi

2013-09-01

The authors investigated the importance of dreams of the deceased in the experiencing of prolonged grief (PG) and posttraumatic stress disorder (PTSD) among Cambodian refugees who survived the Pol Pot genocide (1975-1979). Such dreams were frequent in the last month (52% of those surveyed), and most often involved a relative who died in the Pol Pot period. Past month frequency was correlated with PG severity (r = .59) and PTSD severity (r = .52). The dreams were almost always deeply upsetting because the dreams indicated the deceased to be in a difficult spiritual state. Dreams of the deceased as a central component of PG and PTSD among Cambodian refugees is discussed.

Replica Exchange Molecular Dynamics in the Age of Heterogeneous Architectures

2014-03-01

The rise of GPU-based codes has allowed MD to reach timescales only dreamed of only 5 years ago. Even within this new paradigm there is still need for advanced sampling techniques. Modern supercomputers (e.g. Blue Waters, Titan, Keeneland) have made available to users a significant number of GPUS and CPUS, which in turn translate into amazing opportunities for dream calculations. Replica-exchange based methods can optimally use tis combination of codes and architectures to explore conformational variabilities in large systems. I will show our recent work in porting the program Amber to GPUS, and the support for replica exchange methods, where the replicated dimension could be Temperature, pH, Hamiltonian, Umbrella windows and combinations of those schemes.

Immediate and delayed incorporations of events into dreams: further replication and implications for dream function.

PubMed

Nielsen, Tore A; Kuiken, Don; Alain, Geneviève; Stenstrom, Philippe; Powell, Russell A

2004-12-01

The incorporation of memories into dreams is characterized by two types of temporal effects: the day-residue effect, involving immediate incorporations of events from the preceding day, and the dream-lag effect, involving incorporations delayed by about a week. This study was designed to replicate these two effects while controlling several prior methodological problems and to provide preliminary information about potential functions of delayed event incorporations. Introductory Psychology students were asked to recall dreams at home for 1 week. Subsequently, they were instructed to select a single dream and to retrieve past events related to it that arose from one of seven randomly determined days prior to the dream (days 1-7). They then rated both their confidence in recall of events and the extent of correspondence between events and dreams. Judges evaluated qualities of the reported events using scales derived from theories about the function of delayed incorporations. Average ratings of correspondences between dreams and events were high for predream days 1 and 2, low for days 3 and 4 and high again for days 5-7, but only for participants who rated their confidence in recall of events as high and only for females. Delayed incorporations were more likely than immediate incorporations to refer to events characterized by interpersonal interactions, spatial locations, resolved problems and positive emotions. The findings are consistent with the possibility that processes with circaseptan (about 7 days) morphology underlie dream incorporation and that these processes subserve the functions of socio-emotional adaptation and memory consolidation.

Dopaminergic system and dream recall: An MRI study in Parkinson's disease patients.

We investigated the role of the dopamine system [i.e., subcortical-medial prefrontal cortex (mPFC) network] in dreaming, by studying patients with Parkinson's Disease (PD) as a model of altered dopaminergic transmission. Subcortical volumes and cortical thickness were extracted by 3T-MR images of 27 PD patients and 27 age-matched controls, who were asked to fill out a dream diary upon morning awakening for one week. PD patients do not substantially differ from healthy controls with respect to the sleep, dream, and neuroanatomical measures. Multivariate correlational analyses in PD patients show that dopamine agonist dosage is associated to qualitatively impoverished dreams, as expressed by lower bizarreness and lower emotional load values. Visual vividness (VV) of their dream reports positively correlates with volumes of both the amygdalae and with thickness of the left mPFC. Emotional load also positively correlates with hippocampal volume. Beside the replication of our previous finding on the role of subcortical nuclei in dreaming experience of healthy subjects, this represents the first evidence of a specific role of the amygdala-mPFC dopaminergic network system in dream recall. The association in PD patients between higher dopamine agonist dosages and impoverished dream reports, however, and the significant correlations between VV and mesolimbic regions, however, provide an empirical support to the hypothesis that a dopamine network plays a key role in dream generation. The causal relation is however precluded by the intrinsic limitation of assuming the dopamine agonist dosage as a measure of the hypodopaminergic state in PD.

Few studies have investigated the relation between dream features and cognition in Parkinson's disease (PD), although vivid dreams, hallucinations and cognitive decline have been proposed as successive steps of a pathological continuum. Our objectives were therefore to characterize the dreams of early stage PD and to study the relation between dream characteristics, cognitive function, motor status, depression, dopaminergic treatment, and the presence of REM sleep behaviour disorder (RBD) and hallucinations. Dreams of 19 male PD patients and 21 matched control subjects were classified according to Hall and van de Castle system. h statistics was used to compare the dream content between patients and controls. We tested the relation between patients' dreams characteristics and cognitive function (Frontal assessment battery (FAB) and Mini-Mental State Examination tests) depression (Beck depression inventory), motor function (UPDRS), dopaminergic treatment, the presence of RBD (according to clinical criteria) and hallucinations, using general linear model statistics. Patients and controls differed only on FAB scores. Relevant differences in the Hall and van de Castle scale were found between patient's dreams and those of the control group, regarding animals, aggression/friendliness, physical aggression, befriender (higher in the patient group) and aggressor and bodily misfortunes (lower in the patient group) features. Cognitive and particularly frontal dysfunction had a significant influence on the frequency of physical aggression and animal related features, while dopaminergic doses, depressive symptoms, hallucinations and RBD did not. We found a pattern of dream alteration characterized by heightened aggressiveness and the presence of animals. These were related to more severe frontal dysfunction, which could be the origin of such changes.

To assess prospectively the emotional content of dreams in individuals with the obstructive sleep apnea hypopnea syndrome (OSAHS) and sleepy snorers. Prospective observational study. Forty-seven patients with sleepiness and snoring attending a sleep-disordered breathing clinic, completed a morning diary concerning pleasantness/unpleasantness of their dreams for 10 days, and then had AHI assessed by a limited-channel home sleep study. Participants and groups: Sleepy snorers, AHI < 5: n = 12 (mean age = 51.00 years [SD 7.01], 7 males); AHI 5 -14.9, n = 14 (mean age = 49.71 y [9.73], 12 males); AHI ≥ 15, n = 21 (mean age = 56.33 [11.24], 16 males). All groups reported similar numbers of dreams and nightmares during the diary period. The AHI ≥ 15 group were significantly higher on dream unpleasantness than were the sleepy snorers (p < 0.05); and when only males were analyzed, this difference was also significant (p = 0.01). As AHI increased across the 3 groups, there was a significant decrease in variability of dream emotions (Levene test for homogeneity of variance between the 3 groups, p = 0.018). Mean daytime anxiety and daytime depression were significantly correlated with mean dream unpleasantness and with mean number of nightmares over the diary period. Patients with AHI ≥ 15 had more emotionally negative dreams than patients with AHI < 5. The variation in mean dream emotion decreased with increasing AHI, possibly because sleep fragmentation with increasing AHI results in fewer and shorter dreams, in which emotions are rarer.

Application of ANS fluorescent probes to identify hydrophobic sites on the surface of DREAM.

PubMed

Gonzalez, Walter G; Miksovska, Jaroslava

2014-09-01

DREAM (calsenilin or KChIP-3) is a calcium sensor involved in regulation of diverse physiological processes by interactions with multiple intracellular partners including DNA, Kv4 channels, and presenilin, however the detailed mechanism of the recognition of the intracellular partners remains unclear. To identify the surface hydrophobic surfaces on apo and Ca(2+)DREAM as a possible interaction sites for target proteins and/or specific regulators of DREAM function the binding interactions of 1,8-ANS and 2,6-ANS with DREAM were characterized by fluorescence and docking studies. Emission intensity of ANS-DREAM complexes increases upon Ca(2+) association which is consistent with an overall decrease in surface polarity. The dissociation constants for ANS binding to apoDREAM and Ca(2+)DREAM were determined to be 195±20μM and 62±4μM, respectively. Fluorescence lifetime measurements indicate that two ANS molecules bind in two independent binding sites on DREAM monomer. One site is near the exiting helix of EF-4 and the second site is located in the hydrophobic crevice between EF-3 and EF-4. 1,8-ANS displacement studies using arachidonic acid demonstrate that the hydrophobic crevice between EF-3 and EF-4 serves as a binding site for fatty acids that modulate functional properties of Kv4 channel:KChIP complexes. Thus, the C-terminal hydrophobic crevice may be involved in DREAM interactions with small hydrophobic ligands as well as other intracellular proteins. Copyright © 2014 Elsevier B.V.

Dreams as a source of supernatural agent concepts

PubMed Central

McNamara, Patrick; Bulkeley, Kelly

2015-01-01

We present a theory of the creativity of dreams as well as psychopathology of religious delusions with respect to production of fundamental forms of religious cognition—specifically supernatural agent (SA) cognitions. We suggest that dream cognitions are particularly efficient at producing highly memorable and impactful experiences with SAs because dreams involve three processes that are prerequisites for the generation of god concepts: (1) mental simulations of alternative realities, (2) theory of mind attributions to the extra-natural dream characters and divine beings, and (3) attribution of ultimate value (exemplified by ‘good spirit beings’), and dis-value (exemplified by demonic monsters) to the supernatural dream characters. Because prefrontal cortex is deactivated during rapid eye movements (REM) sleep agentic impulses and internally generated ideas are not reliably attributed to Self or dreamer. Instead an exaggerated degree of agency is attributed to these supernatural dream characters who are then embedded in stories in dreams and in myths of waking life which explain their supernatural abilities. These dream-based SAs are salient characters that are processed in sleep-related memory systems according to rules of Lleweelyn’s ancient art of memory model and therefore more easily remembered and reflected upon during waking life. When REM sleep intrudes into waking consciousness, as is the case with some forms of schizophrenia, religious delusions are more likely to emerge. PMID:25852602

Mammalian DREAM is a conserved protein complex that functions in cellular quiescence. DREAM contains an E2F, a retinoblastoma (RB)-family protein, and the MuvB core (LIN9, LIN37, LIN52, LIN54, and RBBP4). In mammals, MuvB can alternatively bind to BMYB to form a complex that promotes mitotic gene expression. Because BMYB-MuvB is essential for proliferation, loss-of-function approaches to study MuvB have generated limited insight into DREAM function. Here, we report a gene-targeted mouse model that is uniquely deficient for DREAM complex assembly. We have targeted p107 (Rbl1) to prevent MuvB binding and combined it with deficiency for p130 (Rbl2). Our data demonstrate that cells from these mice preferentially assemble BMYB-MuvB complexes and fail to repress transcription. DREAM-deficient mice show defects in endochondral bone formation and die shortly after birth. Micro-computed tomography and histology demonstrate that in the absence of DREAM, chondrocytes fail to arrest proliferation. Since DREAM requires DYRK1A (dual-specificity tyrosine phosphorylation-regulated protein kinase 1A) phosphorylation of LIN52 for assembly, we utilized an embryonic bone culture system and pharmacologic inhibition of (DYRK) kinase to demonstrate a similar defect in endochondral bone growth. This reveals that assembly of mammalian DREAM is required to induce cell cycle exit in chondrocytes. PMID:24710275

Theoretical trajectories: Dreams and dreaming from Freud to Bion.

PubMed

Vinocur Fischbein, Susana; Miramón, Beatriz

2015-08-01

This paper aims at comparing Freud's and Bion's conceptual models on dreams and dreaming. Beyond both authors' shared disposition vis-à-vis problems posed by knowledge, a critical gap opens regarding their differing clinical practices. It is hypothesized that their ideas do not belong to irreconcilable paradigms, but that there are continuities besides discontinuities more frequently highlighted between Freudian statements on psychic functioning--described in his theory on dreams--and Bion's findings in his development of both the original theory and the connections between dreaming and thinking. Firstly, Freud's and Bion's epistemological sources are examined as well as their creative use and historical environment. Then certain general theoretical and clinical issues are considered concerning their theories on dreams, the evolution of their ideas and corresponding clinical contexts. In a third section, their confluences and dissimilarities are dealt with, including clinical vignettes belonging to the authors to illustrate their interpretative modes of working. This is meant to show both an implicit theoretical-clinical complementarity and the fact that, though their routes bifurcate about the function of dreams, there remain connecting paths. Lastly, the final remarks review certain issues that have frequently been controversial between these lines of thought. Copyright © 2015 Institute of Psychoanalysis.

The significance of end-of-life dreams and visions.

PubMed

Grant, Pei; Wright, Scott; Depner, Rachel; Luczkiewicz, Debra

End-of-life dreams and visions (ELDVs) have been well documented through history and across cultures. They appear to affect both dying people and their families deeply, and may be a source of profound meaning and comfort. The aims of the study were to; document hospice patients' ELDV experiences over time using a daily survey, examine the content and subjective significance of ELDVs, and relate the prevalence, content and significance of end-of-life experiences over time until death. Patients (n = 66) in a hospice inpatient unit, between January 2011 and July 2012, were interviewed daily. The interview contained closed questions about the content, frequency and level of comfort or distress of dreams and visions. Most participants reported at least one dream or vision and almost half of the dreams and visions occurred during sleep. Nearly all patients reported that their experience felt real. The most common content featured deceased friends and relatives, followed by living friends and relatives. As participants approached death, comforting dreams and visions of the deceased became more prevalent. End-of-life dreams and visions are commonly experienced during dying. These dreams and visions may be a profound source of potential meaning and comfort to the dying.

Is dream recall underestimated by retrospective measures and enhanced by keeping a logbook? An empirical investigation.

PubMed

Aspy, Denholm J

2016-05-01

In a recent review, Aspy, Delfabbro, and Proeve (2015) highlighted the tendency for retrospective measures of dream recall to yield substantially lower recall rates than logbook measures, a phenomenon they termed the retrospective-logbook disparity. One explanation for this phenomenon is that retrospective measures underestimate true dream recall. Another explanation is that keeping a logbook tends to enhance dream recall. The present study provides a thorough empirical investigation into the retrospective-logbook disparity using a range of retrospective and logbook measures and three different types of logbook. Retrospective-logbook disparities were correlated with a range of variables theoretically related to the retrospective underestimation effect, and retrospective-logbook disparities were greater among participants that reported improved dream recall during the logbook period. These findings indicate that dream recall is underestimated by retrospective measures and enhanced by keeping a logbook. Recommendations for the use of retrospective and logbook measures of dream recall are provided. Copyright © 2016 Elsevier Inc. All rights reserved.

The argument of this paper is to situate The Interpretation of Dreams within an historical context. It is, therefore, impossible to believe Freud entirely when he staged himself in his letters to Fliess as a mere discoverer. In reality Freud also felt he belonged to a learned community of dream specialists, whom I call "dreaming scientists" and "scientific dreamers." Instead of speaking, as Ellenberger does, in terms of influence, I will be offering as an example a portrait of Freud as a reader of two French authors, Maury, and indirectly, Hervey de Saint-Denys. I will analyze how Freud staged himself as replacing Maury and dreaming sometimes like Hervey de Saint-Denys. My premise in this work is that we must forget Freud, in order to adventure into a learned dream culture peculiar to the nineteenth century. Only afterwards can we come back to Freud and place him in this context as a creative heir.

The association of mammalian DREAM complex and HPV16 E7 proteins

The mammalian DREAM (Drosophila, RB, E2F, and Myb) complex was discovered in 2004 by several research groups. It was initially identified in Drosophila followed by Caenorhaditis elegans and later in mammalian cells. The composition of DREAM is temporally regulated during cell cycle; being associated with E2F-4 and either p107 or p130 in G0/G1 (repressive DREAM complexes) and with B-myb transcription factor in S/G2 (activator DREAM complex). High risk human papillomavirus (HPV) E6 and E7 oncoproteins expression are important for malignant transformation of cervical cancer cells. In particular, the E7 of high risk HPV binds to pRB family members (pRB, p107 and p130) for degradation. It has recently been discovered that the p107 and p130 ‘pocket proteins’ are members of mammalian DREAM complexes. With this understanding, we would like to hypothesise the mammalian DREAM complex could plays a critical role for malignant transformation in cervical cancer cells. PMID:26885443

Brain basis of self: self-organization and lessons from dreaming

PubMed Central

Kahn, David

2013-01-01

Through dreaming, a different facet of the self is created as a result of a self-organizing process in the brain. Self-organization in biological systems often happens as an answer to an environmental change for which the existing system cannot cope; self-organization creates a system that can cope in the newly changed environment. In dreaming, self-organization serves the function of organizing disparate memories into a dream since the dreamer herself is not able to control how individual memories become weaved into a dream. The self-organized dream provides, thereby, a wide repertoire of experiences; this expanded repertoire of experience results in an expansion of the self beyond that obtainable when awake. Since expression of the self is associated with activity in specific areas of the brain, the article also discusses the brain basis of the self by reviewing studies of brain injured patients, discussing brain imaging studies in normal brain functioning when focused, when daydreaming and when asleep and dreaming.

Testing the involvement of the prefrontal cortex in lucid dreaming: a tDCS study.

Stumbrys, Tadas; Erlacher, Daniel; Schredl, Michael

2013-12-01

Recent studies suggest that lucid dreaming (awareness of dreaming while dreaming) might be associated with increased brain activity over frontal regions during rapid eye movement (REM) sleep. By applying transcranial direct current stimulation (tDCS), we aimed to manipulate the activation of the dorsolateral prefrontal cortex (DLPFC) during REM sleep to increase dream lucidity. Nineteen participants spent three consecutive nights in a sleep laboratory. On the second and third nights they randomly received either 1 mA tDCS for 10 min or sham stimulation during each REM period starting with the second one. According to the participants' self-ratings, tDCS over the DLPFC during REM sleep increased lucidity in dreams. The effects, however, were not strong and found only in frequent lucid dreamers. While this indicates some preliminary support for the involvement of the DLPFC in lucid dreaming, further research, controlling for indirect effects of stimulation and including other brain regions, is needed.

Screening wish theories: dream psychologies and early cinema.

PubMed

Marinelli, Lydia

2006-03-01

The analogy between dream and film represents a central thread in the psychoanalytic discussion of cinema. Using examples taken from films created between 1900 and 1906, this paper develops a typology of dream scenes in early film. The basis for the proposed typology is provided by the dream knowledge in circulation toward the end of the nineteenth century. This knowledge was fed by a great variety of sources, some of them in the proximity of scientific research and some of them far from it, including wish-fulfilling prognostic models and those based on the reservoir of memory or on bodily stimuli. By setting cinema in a context of contemporary dream psychologies, it is possible to trace the specific conditions under which the analogy between dream and cinema could become effective.

Lucid dreaming: an age-dependent brain dissociation.

The current study focused on the distribution of lucid dreams in school children and young adults. The survey was conducted on a large sample of students aged 6-19 years. Questions distinguished between past and current experience with lucid dreams. Results suggest that lucid dreaming is quite pronounced in young children, its incidence rate drops at about age 16 years. Increased lucidity was found in those attending higher level compared with lower level schools. Taking methodological issues into account, we feel confident to propose a link between the natural occurrence of lucid dreaming and brain maturation. © 2012 European Sleep Research Society.

Dreams in ancient Greek Medicine.

Dreams preoccupied the Greek and Roman world in antiquity, therefore they had a prominent role in social, philosophical, religious, historical and political life of those times. They were considered as omens and prophetic signs of future events in private and public life, and that was particularly accentuated when elements of actions which took place in the plot of dreams were associated directly or indirectly with real events. This is why it was important to use them in divination, and helped the growth of superstition and folklore believes. Medicine as a science and an anthropocentric art, could not ignore the importance of dreams, having in mind their popularity in antiquity. In ancient Greek medicine dreams can be divided into two basic categories. In the first one -which is related to religious medicine-dreams experienced by religionists are classified, when resorted to great religious sanctuaries such as those of Asclepius (Asclepieia) and Amphiaraos (Amfiaraeia). These dreams were the essential element for healing in this form of religious medicine, because after pilgrims underwent purifications they went to sleep in a special dwelling of the sanctuaries called "enkoimeterion" (Greek: the place to sleep) so that the healing god would come to their dreams either to cure them or to suggest treatment. In ancient Greek literature there are many reports of these experiences, but if there may be phenomena of self-suggestion, or they could be characterized as propaganda messages from the priesthood of each sanctuary for advertising purposes. The other category concerns the references about dreams found in ancient Greek medical literature, where one can find the attempts of ancient Greek physicians to interpret these dreams in a rational way as sings either of a corporal disease or of psychological distress. This second category will be the object of our study. Despite the different ways followed by each ancient Greek physician in order to explain dreams, their common intention was to give a rational answer for the creation and content of dreams setting aside any supernatural beliefs. In addition they tried to explain in a scientific way the correlation that could have emerged between the story that took place in dreams and the events that happened in everyday life. Nevertheless, ancient Greek physicians focused especially on nightmares, which were associated with physical problems. For those physicians these nightmares included information about the corporal disease of the patient, which had a reflection in the dream, and they could help them to diagnose the problem in order to restore balance of the body.

1997-01-01

The dream of producing an air-breathing, hydrogen fueled, hypervelocity aircraft has been before the aerospace community for decades. However, such a craft has not yet been realized, even in an experimental form. Despite the simplicity and beauty of the concept, many formidable problems must be overcome to make this dream a reality. This paper summarizes the aero/aerothermodynamic issues that must be addressed to make the dream a reality and discusses how aerothermodynamics facilities and their modem companion, real-gas computational fluid dynamics (CFD), can help solve the problems blocking the way to realizing the dream. The approach of the paper is first to outline the concept of an air-breathing hypersonic vehicle and then discuss the nose-to-tail aerothermodynamics issues and special aerodynamic problems that arise with such a craft. Then the utility of aerothermodynamic facilities and companion CFD analysis is illustrated by reviewing results from recent United States publications wherein these problems have been addressed. Papers selected for the discussion have k e n chosen such that the review will serve to survey important U.S. aero/aerothermodynamic real gas and conventional wind tunnel facilities that are useful in the study of hypersonic, hydrogen propelled hypervelocity vehicles.

The author presents several dreams reported by psychosomatic patients which contain an overt or disguised act of suicide. In the latter instances various transformations of the act of suicide had been brought about by the defensive functions of the dreaming ego. Paradoxically, in several of these instances it was the very efforts of the dreaming ego to defend itself which allowed the suicidal impulse to reach its consummation.

The dream between neuroscience and psychoanalysis.

PubMed

Mancia, M

2004-07-01

The dream is tackled sometimes from the neurobiological viewpoint, sometimes from the neuropsychological angle, or from the positions of experimental and psychoanalytical psychology. Interest in dreams started with psychoanalysis in 1900, and 53 years later the discovery of REM sleep by Aserinski and Kleitman, and subsequent psychophysiological findings took the dream into the realm of biology. The dichotomous model of REM and non-REM sleep is described, as a basis for thought-like activity (non-REM sleep) and dreaming (REM sleep). This led to Hobson and McCarley's theory of activation-synthesis, suggesting that the mind while dreaming is simply the brain self-activated in REM sleep. Psychophysiological research has shown that people dream in all phases of sleep, from falling asleep to waking, but that the characteristics of the dreams may differ in the different phases. Bio-imaging studies indicate that during REM sleep there is activation of the pons, the amygdala bilaterally, and the anterior cingulate cortex, and disactivation of the posterior cingulate cortex and the prefrontal cortex. The images suggest there is a neuroanatomical frame within which dreams can be generated and then forgotten. Psychoanalysis studies the dream from a completely different angle. Freud believed it was the expression of hallucinatory satisfaction of repressed desires. Today it is interpreted as the expression of a representation of the transference in the hic et nunc of the session. At the same time it also has symbol-generating functions which provide an outlet by which affective experiences and fantasies and defences stored as parts of an unrepressed unconscious in the implicit memory can be represented in pictorial terms, then thought and rendered verbally. From the psychoanalytical point of view, the dream transcends neurobiological knowledge, and looks like a process of internal activation that is only apparently chaotic, but is actually rich in meanings, arising from the person's affective and emotional history.

Time for actions in lucid dreams: effects of task modality, length, and complexity

PubMed Central

Erlacher, Daniel; Schädlich, Melanie; Stumbrys, Tadas; Schredl, Michael

2014-01-01

The relationship between time in dreams and real time has intrigued scientists for centuries. The question if actions in dreams take the same time as in wakefulness can be tested by using lucid dreams where the dreamer is able to mark time intervals with prearranged eye movements that can be objectively identified in EOG recordings. Previous research showed an equivalence of time for counting in lucid dreams and in wakefulness (LaBerge, 1985; Erlacher and Schredl, 2004), but Erlacher and Schredl (2004) found that performing squats required about 40% more time in lucid dreams than in the waking state. To find out if the task modality, the task length, or the task complexity results in prolonged times in lucid dreams, an experiment with three different conditions was conducted. In the first condition, five proficient lucid dreamers spent one to three non-consecutive nights in the sleep laboratory. Participants counted to 10, 20, and 30 in wakefulness and in their lucid dreams. Lucidity and task intervals were time stamped with left-right-left-right eye movements. The same procedure was used for the second condition where eight lucid dreamers had to walk 10, 20, or 30 steps. In the third condition, eight lucid dreamers performed a gymnastics routine, which in the waking state lasted the same time as walking 10 steps. Again, we found that performing a motor task in a lucid dream requires more time than in wakefulness. Longer durations in the dream state were present for all three tasks, but significant differences were found only for the tasks with motor activity (walking and gymnastics). However, no difference was found for relative times (no disproportional time effects) and a more complex motor task did not result in more prolonged times. Longer durations in lucid dreams might be related to the lack of muscular feedback or slower neural processing during REM sleep. Future studies should explore factors that might be associated with prolonged durations. PMID:24474942

Maternal representations in the dreams of pregnant women: a prospective comparative study

Dreams are thought to respond to self- and socially-relevant situations that evoke strong emotions and require rapid adaptation. First pregnancy is such a situation during which maternal mental representations (MMR) of the unborn baby, the self and significant others undergo remodeling. Some studies suggest that dreams during pregnancy contain more MMR and are more dysphoric, but such studies contain important methodological flaws. We assessed whether dreamed MMR, like waking MMR, change from the 7th month of pregnancy to birth, and whether pregnancy–related themes and non-pregnancy characteristics are also transformed. Sixty non-pregnant and 59 pregnant women (37 early and 22 late 3rd trimester) completed demographic and psychological questionnaires and 14-day home dream logs. Dream reports were blindly rated according to four dream categories: (1) Dreamed MMR, (2) Quality of baby/child representations, (3) Pregnancy-related themes, (4) Non-pregnancy characteristics. Controlling for age, relationship and employment status, education level and state anxiety, women in both pregnant groups reported more dreams depicting themselves as a mother or with babies/children than did non-pregnant women (all p = 0.006). Baby/child representations were less specific in the late 3rd than in the early 3rd trimester (p = 0.005) and than in non-pregnant women (p = 0.01). Pregnant groups also had more pregnancy, childbirth and fetus themes (all p = 0.01). Childbirth content was higher in late than in early 3rd trimester (p = 0.01). Pregnant groups had more morbid elements than did the non-pregnant group (all p < 0.05). Dreaming during pregnancy appears to reflect daytime processes of remodeling MMR of the woman as a mother and of her unborn baby, and parallels a decline in the quality of baby/child representations in the last stage of pregnancy. More frequent morbid content in late pregnancy suggests that the psychological challenges of pregnancy are reflected in a generally more dysphoric emotional tone in dream content. PMID:23986734

Background Lucid Dreams are a form of dream life, during which the dreamer may be aware that he/she is dreaming, can stop/re-start the dreams, depending on the pleasantness or unpleasant nature of the dream, and experiences the dream as if he/she were fully awake. Depending on their content, they may be pleasant, un-pleasant or terrifying, at least in the context of patients, who also exhibit characteristics of Reward Deficiency Syndrome (RDS) and Posttraumatic Stress Disorder (PTSD). Case Series We present eight clinical cases, with known substance abuse, childhood abuse and diagnosed PTSD/RDS. The administration of a putative dopamine agonist, KB200Z™, was associated with the elimination of unpleasant and/or terrifying, lucid dreams in 87.5% of the cases presented, whereas one very heavy cocaine abuser showed a minimal response. These results required the continuous use of this nutraceutical. The lucid dreams themselves were distinguishable from typical, PTSD nightmares insofar as their content did not appear to reflect a symbolic rendition of an originally-experienced, historical trauma. Each of the cases was diagnosed with a form of RDS, i.e., ADHD, ADD, and/or Tourette’s syndrome. They all also suffered from some form of Post-Traumatic-Stress-Disorder (PTSD) and other psychiatric diagnoses as well. Conclusion The reduction or elimination of terrifying Lucid Dreams seemed to be dependent on KB220Z, whereby voluntary stopping of the agent results in reinstatement of the terrifying non-pleasant nature of the dreams. Following more required research on a much larger population we anticipate confirmation of these seemingly interesting observations. If these results in a small number of patients are indeed confirmed we may have found a frontline solution to a very perplexing and complicated symptom known as lucid dreams. PMID:26065033

Dreams: the convergence of neurobiologic and psychoanalytic perspectives.

PubMed

Been, H

1997-01-01

Fromm's Aristotelian statement that "Dreaming is a meaningful expression of any kind of mental activity under the condition of sleep" (Fromm, 1951, p. 25) is similar to a modern neurobiological conclusion about the dreaming process. The current data from the neurosciences lead to the definition of dreams as a neuropsychological event during sleep whose manifest contents are affect laden, visual, auditory, and kinesthetic. Their functions are adaptive and problem solving in themselves. They are part of the brain's connectionist information-processing system which channel, compare, and integrate current affect-laden memories with memories of past successful strategies. Thus, the neurobiological perspective of dreams provides an underlying neuroanatomical and information-processing matrix for the dream process that further supports the current psychoanalytic view concerning their assimilative and accommodative functions. In conclusion, I would like to return to the termination phase of Mr. M's therapy. This patient planned to leave therapy approximately 22 months after the occurrence of Dream 2, as this dream had predicted. He was to be married and move to another city. Although I felt somewhat anxious about his leaving, despite his significant progress, we agreed to a termination date. Just prior to the second-to-last session Mr. M had the following dream: It took place in a large gothic building in a zoo. It is dark and depressing and filled with cages of rhesus monkeys. I go around with a nurse to inoculate the monkeys. I am scared of the virus. My future wife appears. She is immune to the virus. She is brave and she rescues me. The patient seemed pleased in relating his dream, and it offered resolution and closure for both of us despite a paucity of discussion. Two years later I received a letter from him in which he stated that he was well and had no additional "monkey dreams."

Dreaming as mind wandering: evidence from functional neuroimaging and first-person content reports.

PubMed

Fox, Kieran C R; Nijeboer, Savannah; Solomonova, Elizaveta; Domhoff, G William; Christoff, Kalina

2013-01-01

Isolated reports have long suggested a similarity in content and thought processes across mind wandering (MW) during waking, and dream mentation during sleep. This overlap has encouraged speculation that both "daydreaming" and dreaming may engage similar brain mechanisms. To explore this possibility, we systematically examined published first-person experiential reports of MW and dreaming and found many similarities: in both states, content is largely audiovisual and emotional, follows loose narratives tinged with fantasy, is strongly related to current concerns, draws on long-term memory, and simulates social interactions. Both states are also characterized by a relative lack of meta-awareness. To relate first-person reports to neural evidence, we compared meta-analytic data from numerous functional neuroimaging (PET, fMRI) studies of the default mode network (DMN, with high chances of MW) and rapid eye movement (REM) sleep (with high chances of dreaming). Our findings show large overlaps in activation patterns of cortical regions: similar to MW/DMN activity, dreaming and REM sleep activate regions implicated in self-referential thought and memory, including medial prefrontal cortex (PFC), medial temporal lobe structures, and posterior cingulate. Conversely, in REM sleep numerous PFC executive regions are deactivated, even beyond levels seen during waking MW. We argue that dreaming can be understood as an "intensified" version of waking MW: though the two share many similarities, dreams tend to be longer, more visual and immersive, and to more strongly recruit numerous key hubs of the DMN. Further, whereas MW recruits fewer PFC regions than goal-directed thought, dreaming appears to be characterized by an even deeper quiescence of PFC regions involved in cognitive control and metacognition, with a corresponding lack of insight and meta-awareness. We suggest, then, that dreaming amplifies the same features that distinguish MW from goal-directed waking thought.

Time-of-night variations in the story-like organization of dream experience developed during rapid eye movement sleep.

This study aimed to investigate the cycles (2nd/4th) and duration-related (5/10 min) variations in the story-like organization of dream experience elaborated during rapid eye movement (REM) sleep. Dream reports were analysed using story grammar rules. Reports were provided by those subjects (14 of 22) capable of reporting a dream after each of the four awakenings provoked in 2 consecutive nights during REM sleep of the 2nd and 4th cycles, after periods of either 5 or 10 min, counterbalanced across the nights. Two researchers who were blind as to the sleep condition scored the dream reports independently. The values of the indicators of report length (measured as value of total word count) and of story-like organization of dream reports were matched taking time-of-night (2nd and 4th cycles) and REM duration (5 versus 10 min) as factors. Two-way analyses of variance showed that report length increased significantly in 4th-cycle REM sleep and nearly significantly for longer REM duration, whereas the number of dream-stories per report did not vary. The indices of sequential (number of statements describing the event structure developed in the story) and hierarchical (number of episodes per story) organization increased significantly only in dream-stories reported after 10 min of 4th-cycle REM sleep. These findings indicate that the characteristics of structural organization of dream-stories vary along with time of night, and suggest that the elaboration of a long and complex dream-story requires a fairly long time and the availability of a great amount of cognitive resources to maintain its continuity and coherence. © 2014 European Sleep Research Society.

In two minds? Is schizophrenia a state 'trapped' between waking and dreaming?

PubMed

Llewellyn, Sue

2009-10-01

This paper proposes that schizophrenia is a state of mind/brain 'trapped' in-between waking and dreaming. Furthermore, it suggests that both waking and dreaming are functional. An in-between state would be disordered; neither waking nor dreaming would function properly, as the mind/brain would be attempting two, ultimately incompatible, sets of tasks simultaneously. In support of this hypothesis, evidence is synthesised across four different domains: the chemistry of the dreaming state; work on dreaming as functional for memory; the membrane theory of schizophrenia; and chaos theory. The brain produces itself; self-organizing through its modulatory systems. Differentiation between dreaming and waking is achieved through aminergic/cholinergic/dopaminergic reciprocity. Chaos theory indicates that self-organizing systems function most creatively on the 'edge of chaos'; a state which lies between order and disorder. In the mind/brain 'order' represents rigid differentiation between waking and dreaming, whereas 'disorder' results from their interpenetration. How could the latter occur? In sum, the causal sequence would be as follows. Genetic susceptibility to schizophrenia is expressed through fatty acid deficiencies which precipitate neuronal cell membrane abnormalities. In consequence, all neurotransmitter systems become disrupted. Ultimately, the reciprocal interaction between aminergic/cholinergic neuromodulation breaks down. Disrupted cholinergic input interferes with the reciprocal relationship between mesolimbic and mesocortical dopaminergic systems. Loss of reciprocity between aminergic, cholinergic and dopaminergic neuromodulation results in chronic interpenetration; a 'trapped' state, in-between waking and dreaming results. This would be 'schizophrenia'. Currently, imaging techniques do not capture dynamic neuromodulation, so this hypothesis cannot yet be tested inductively. However, the paper suggests that further evidence would be gained through a closer attention to the phenomenology of schizophrenia in the waking and dreaming states.

Coping with stress: dream interpretation in the Mapuche family.

PubMed

Degarrod, L N

1990-06-01

Dreams are shared and interpreted daily within the family unit among the Mapuche Indians of Chile. This anthropological study examines the communicative aspect of dream sharing and interpreting among Mapuche families undergoing emotional and physical stress. Specifically, it investigates the ways in which the Mapuche dream interpretation system provides the family members with another means of interaction and a way of solving their problems. It also examines how individuals influence their attitudes towards one another by communally participating in the dream interpretation process, and in its narrative performance. The data used in this research consists of dreams and of their interpretations, collected in the natural setting, from two families with members suffering of witchcraft, and fear of death. This information was collected over a period of 17 months from October 1985 to March 1987 with a Fulbright-Hayes Doctoral Dissertation Grant.

Dreaming and waking: similarities and differences revisited.

PubMed

Kahan, Tracey L; LaBerge, Stephen P

2011-09-01

Dreaming is often characterized as lacking high-order cognitive (HOC) skills. In two studies, we test the alternative hypothesis that the dreaming mind is highly similar to the waking mind. Multiple experience samples were obtained from late-night REM sleep and waking, following a systematic protocol described in Kahan (2001). Results indicated that reported dreaming and waking experiences are surprisingly similar in their cognitive and sensory qualities. Concurrently, ratings of dreaming and waking experiences were markedly different on questions of general reality orientation and logical organization (e.g., the bizarreness or typicality of the events, actions, and locations). Consistent with other recent studies (e.g., Bulkeley & Kahan, 2008; Kozmová & Wolman, 2006), experiences sampled from dreaming and waking were more similar with respect to their process features than with respect to their structural features.

The DREAM model uses Kalman filtering techniques that combine the strengths of new physical models of the radiation belts with electron observations from long-term satellite systems such as GPS and geosynchronous systems. DREAM includes a physics model for the production and long-term evolution of artificial radiation belts from high altitude nuclear explosions. DREAM has been validated against satellites in arbitrary orbits and consistently produces more accurate resultsmore » than existing models. Tools for user-specific applications and graphical displays are in beta testing and a real-time version of DREAM has been in continuous operation since November 2009.« less

Jung on the nature and interpretation of dreams: a developmental delineation with cognitive neuroscientific responses.

PubMed

Zhu, Caifang

2013-12-01

Post-Jungians tend to identify Jung's dream theory with the concept of compensation; they tend to believe that Jung's radically open stand constitutes his dream theory in its entirety. However, Jung's theory regarding dreams was a product of an evolving process throughout his whole intellectual and professional life. Unfortunately, the theory has not been understood in such a developmental light. Based on a historical and textual study of all dream articles found throughout The Collected Works of C.G. Jung, this paper maps a concise three-phase trajectory of Jung's changing views on dreams and interpretation. The paper posits that Jung's last essay, "Symbols and the Interpretation of Dreams" (1961), epitomizes his final stand, although such a stand is also reflected in a less explicit and less emphatic way during the latter period of the second phase. The paper also briefly addresses where Jung and Jungians have been enigmatic or negligent. For example, it has not been explicated fully why compensation as slight modifications and compensation as parallels to waking life situations are rare in Jung's cases In addition, contemporary cognitive and neuroscientific approaches to the study of dreams, as represented by Harry Hunt, William Domhoff, and Allan Hobson, among others, are presented in connection with Jung. The juxtaposition of Jungian, cognitive, and neuroscientific approaches showcases how cognitive and scientific findings challenge, enrich, and in some ways confirm Jung's dream theory and praxis.

Downstream regulatory element antagonistic modulator (DREAM) was originally identified in neuroendocrine cells as a calcium-binding protein that specifically binds to downstream regulatory elements (DRE) on DNA, and represses transcription of its target genes. To explore the possibility that DREAM may regulate the endocrine activity of the thyroid gland, we analyzed its mRNA expression in undifferentiated and differentiated thyroid cells. We demonstrated that DREAM is expressed in the normal thyroid tissue as well as in differentiated thyroid cells in culture while it is absent in FRT poorly differentiated cells. In the present work, we also show that DREAM specifically binds tomore » DRE sites identified in the 5' untranslated region (UTR) of the thyroid-specific transcription factors Pax8 and TTF-2/FoxE1 in a calcium-dependent manner. By gel retardation assays we demonstrated that thapsigargin treatment increases the binding of DREAM to the DRE sequences present in Pax8 and TTF-2/Foxe1 5' UTRs, and this correlates with a significant reduction of the expression of these genes. Interestingly, in poorly differentiated thyroid cells overexpression of exogenous DREAM strongly inhibits Pax8 expression. Moreover, we provide evidence that a mutated form of DREAM unable to bind Ca{sup 2+} interferes with thyroid cell proliferation. Therefore, we propose that in thyroid cells DREAM is a mediator of the calcium-signaling pathway and it is involved in the regulation of thyroid cell function.« less

Mammalian sleep

Staunton, Hugh

2005-05-01

This review examines the biological background to the development of ideas on rapid eye movement sleep (REM sleep), so-called paradoxical sleep (PS), and its relation to dreaming. Aspects of the phenomenon which are discussed include physiological changes and their anatomical location, the effects of total and selective sleep deprivation in the human and animal, and REM sleep behavior disorder, the latter with its clinical manifestations in the human. Although dreaming also occurs in other sleep phases (non-REM or NREM sleep), in the human, there is a contingent relation between REM sleep and dreaming. Thus, REM is taken as a marker for dreaming and as REM is distributed ubiquitously throughout the mammalian class, it is suggested that other mammals also dream. It is suggested that the overall function of REM sleep/dreaming is more important than the content of the individual dream; its function is to place the dreamer protagonist/observer on the topographical world. This has importance for the developing infant who needs to develop a sense of self and separateness from the world which it requires to navigate and from which it is separated for long periods in sleep. Dreaming may also serve to maintain a sense of ‘I’ness or “self” in the adult, in whom a fragility of this faculty is revealed in neurological disorders.

Terror and bliss? Commonalities and distinctions between sleep paralysis, lucid dreaming, and their associations with waking life experiences.

PubMed

Denis, Dan; Poerio, Giulia L

2017-02-01

Sleep paralysis and lucid dreaming are both dissociated experiences related to rapid eye movement (REM) sleep. Anecdotal evidence suggests that episodes of sleep paralysis and lucid dreaming are related but different experiences. In this study we test this claim systematically for the first time in an online survey with 1928 participants (age range: 18-82 years; 53% female). Confirming anecdotal evidence, sleep paralysis and lucid dreaming frequency were related positively and this association was most apparent between lucid dreaming and sleep paralysis episodes featuring vestibular-motor hallucinations. Dissociative experiences were the only common (positive) predictor of both sleep paralysis and lucid dreaming. Both experiences showed different associations with other key variables of interest: sleep paralysis was predicted by sleep quality, anxiety and life stress, whereas lucid dreaming was predicted by a positive constructive daydreaming style and vividness of sensory imagery. Overall, results suggest that dissociative experiences during wakefulness are reflected in dissociative experiences during REM sleep; while sleep paralysis is related primarily to issues of sleep quality and wellbeing, lucid dreaming may reflect a continuation of greater imaginative capacity and positive imagery in waking states. © 2016 The Authors.

Deregulated protein and Ca2+ homeostasis underlie synaptic dysfunction and neurodegeneration in Huntington disease (HD); however, the factors that disrupt homeostasis are not fully understood. Here, we determined that expression of downstream regulatory element antagonist modulator (DREAM), a multifunctional Ca2+-binding protein, is reduced in murine in vivo and in vitro HD models and in HD patients. DREAM downregulation was observed early after birth and was associated with endogenous neuroprotection. In the R6/2 mouse HD model, induced DREAM haplodeficiency or blockade of DREAM activity by chronic administration of the drug repaglinide delayed onset of motor dysfunction, reduced striatal atrophy, and prolonged life span. DREAM-related neuroprotection was linked to an interaction between DREAM and the unfolded protein response (UPR) sensor activating transcription factor 6 (ATF6). Repaglinide blocked this interaction and enhanced ATF6 processing and nuclear accumulation of transcriptionally active ATF6, improving prosurvival UPR function in striatal neurons. Together, our results identify a role for DREAM silencing in the activation of ATF6 signaling, which promotes early neuroprotection in HD. PMID:26752648

A global approach to the management of EMR (Electronic Medical Records) of patients with HIV/AIDS in Sub-Saharan Africa: the experience of DREAM Software

PubMed Central

2009-01-01

Background The DREAM Project operates within the framework of the national health systems of several sub-Saharan African countries and aims to introduce the essential components of an integrated strategy for the prevention and treatment of HIV/AIDS. The project is intended to serve as a model for a wide-ranging scale-up in the response to the epidemic. This paper aims to show DREAM's challenges and the solutions adopted. One of the solutions is the efficient management of the clinical data regarding the treatment of the patients and epidemiological analyses. Methods Specific software for the management of the patients' EMR has been created within the DREAM programme in order to deal with the challenges deriving from the context in which DREAM operates. Setting up a computer infrastructure in health centres, providing a power supply, as well as managing the data and the project resources efficiently and reliably, are some of the questions that have been analysed in this study. Results Over the years this software has proved that it is able to respond to the need for efficient management of the clinical data and organization of the health centres. Today it is used in 10 countries in sub-Saharan Africa by thousands of professionals and by now it has reached its fourth version. The medical files of over 73,000 assisted patients are managed by this software and the data collected with it have become essential for the epidemiological research that is carried out to improve the effectiveness of the therapy. Conclusion Sub-Saharan Africa is the region hardest hit by HIV and AIDS in the world. However, the resources and responses adopted so far, to confront the epidemic, have at times been rather minimalist. The DREAM project has faced the battle against the epidemic by equipping itself with qualitative standards comparable to Western ones. The experience of DREAM has revealed that it is indeed possible to guarantee levels of excellence in developing countries, also in the sphere of ICT (Information and Communication Technology), thus making the intervention even more effective and contributing to bridging the digital divide.

A study of fatal pedestrian crashes at rural low-volume road intersections in southwest China.

Although intersections correspond to a small proportion of the entire roadway system, they account for a disproportionally high number of fatal pedestrian crashes, especially on rural roads situated in low- and middle-income countries. This article examines pedestrian safety at rural intersections and suggests applicable accident prevention treatments by providing an in-depth analysis of 28 fatal pedestrian crashes from 8 low-volume roads in southwest China. The driving reliability and error analysis method (DREAM) is a method to support a systematic classification of accident causation information and to facilitate aggregation of that information into patterns of contributing factors. This is the first time that DREAM was used to analyze pedestrian-vehicle crashes and provide suggestions for road improvements in China. The key issues adversely affecting pedestrian safety can be organized in 4 distinctive thematic categories, namely, deficient intersection safety infrastructure, lack of pedestrian safety education, inadequate driver training, and insufficient traffic law enforcement. Given that resources for traffic safety investments in rural areas are limited, it is determined that the potential countermeasures should focus on low-cost, easily implementable, and long-lasting measures increasing the visibility and predictability of pedestrian movement and reducing speeding and irresponsible driving among drivers and risk-taking behaviors among pedestrians. Accident prevention treatments are suggested based on their suitability for rural areas in southwest China. These countermeasures include introducing better access management and traffic calming treatments, providing more opportunities for pedestrian education, and enhancing the quality of driver training and traffic law enforcement.

DREAMS and IMAGE: A Model and Computer Implementation for Concurrent, Life-Cycle Design of Complex Systems

Hale, Mark A.; Craig, James I.; Mistree, Farrokh; Schrage, Daniel P.

1995-01-01

Computing architectures are being assembled that extend concurrent engineering practices by providing more efficient execution and collaboration on distributed, heterogeneous computing networks. Built on the successes of initial architectures, requirements for a next-generation design computing infrastructure can be developed. These requirements concentrate on those needed by a designer in decision-making processes from product conception to recycling and can be categorized in two areas: design process and design information management. A designer both designs and executes design processes throughout design time to achieve better product and process capabilities while expanding fewer resources. In order to accomplish this, information, or more appropriately design knowledge, needs to be adequately managed during product and process decomposition as well as recomposition. A foundation has been laid that captures these requirements in a design architecture called DREAMS (Developing Robust Engineering Analysis Models and Specifications). In addition, a computing infrastructure, called IMAGE (Intelligent Multidisciplinary Aircraft Generation Environment), is being developed that satisfies design requirements defined in DREAMS and incorporates enabling computational technologies.

The authors investigated the frequency and correlates of déjà vu experiences in 386 healthy adult volunteers recruited from several areas in Japan. Déjà vu experiences and related experiences were evaluated using the Inventory of Déjà vu Experiences Assessment. Déjà vu experiences were observed by 294 (76.2%) of the 386 participants. Persons who experienced déjà vu were younger and more educated than persons who had not experienced it. There were no differences in the frequency of déjà vu experiences based on sex, hand preference, or area of residence. Subsequent factor analysis associated déjà vu with precognitive dreams and remembering dreams as dream- and memory-related factors rather than with the dissociation-related factors of depersonalization, derealization, jamais vu, and daydreams or with mental activity-related factors such as paranormal quality and travel frequency. Results suggest that déjà vu experiences are associated with good memory function.

Free Energy and Virtual Reality in Neuroscience and Psychoanalysis: A Complexity Theory of Dreaming and Mental Disorder

PubMed Central

Hopkins, Jim

2016-01-01

The main concepts of the free energy (FE) neuroscience developed by Karl Friston and colleagues parallel those of Freud's Project for a Scientific Psychology. In Hobson et al. (2014) these include an innate virtual reality generator that produces the fictive prior beliefs that Freud described as the primary process. This enables Friston's account to encompass a unified treatment—a complexity theory—of the role of virtual reality in both dreaming and mental disorder. In both accounts the brain operates to minimize FE aroused by sensory impingements—including interoceptive impingements that report compliance with biological imperatives—and constructs a representation/model of the causes of impingement that enables this minimization. In Friston's account (variational) FE equals complexity minus accuracy, and is minimized by increasing accuracy and decreasing complexity. Roughly the brain (or model) increases accuracy together with complexity in waking. This is mediated by consciousness-creating active inference—by which it explains sensory impingements in terms of perceptual experiences of their causes. In sleep it reduces complexity by processes that include both synaptic pruning and consciousness/virtual reality/dreaming in REM. The consciousness-creating active inference that effects complexity-reduction in REM dreaming must operate on FE-arousing data distinct from sensory impingement. The most relevant source is remembered arousals of emotion, both recent and remote, as processed in SWS and REM on “active systems” accounts of memory consolidation/reconsolidation. Freud describes these remembered arousals as condensed in the dreamwork for use in the conscious contents of dreams, and similar condensation can be seen in symptoms. Complexity partly reflects emotional conflict and trauma. This indicates that dreams and symptoms are both produced to reduce complexity in the form of potentially adverse (traumatic or conflicting) arousals of amygdala-related emotions. Mental disorder is thus caused by computational complexity together with mechanisms like synaptic pruning that have evolved for complexity-reduction; and important features of disorder can be understood in these terms. Details of the consilience among Freudian, systems consolidation, and complexity-reduction accounts appear clearly in the analysis of a single fragment of a dream, indicating also how complexity reduction proceeds by a process resembling Bayesian model selection.

The regularity of gender differences reported in the manifest content of dreams has been generally interpreted as a reflection of biological differences and/or early socialization. Research we have conducted on women's dreams reveals that many of their characteristics are linked to social roles. Findings suggest that the new occupational roles of women, combined with the traditional mother role decrease stereotypic feminine dream imagery. Age and life cycle phase from adolescence to old age, also appear to impact on dreams. PMID:1958649

Forgotten Dreams: Recalling the Patient in British Psychotherapy, 1945–60

The forgotten dream proved central to the early development of Sigmund Freud’s psychoanalytic technique in The Interpretation of Dreams (1900). However, little attention has been paid to the shifting uses of forgotten dreams within psychotherapeutic practice over the course of the twentieth century. This paper argues that post-war psychotherapists in London, both Jungian and Freudian, developed a range of subtly different approaches to dealing with their patients’ forgotten dreams. Theoretical commitments and institutional cultures shaped the work of practitioners including Donald Winnicott, Melanie Klein, Anna Freud, and Edward Griffith. By drawing on diaries and case notes, this paper also identifies the active role played by patients in negotiating the mechanics of therapy, and the appropriate response to a forgotten dream. This suggests a broader need for a detailed social history of post-Freudian psychotherapeutic technique, one that recognises the demands of both patients and practitioners. PMID:25766542

Here we show that the transcription-repressor DREAM binds to the A20 promoter to repress the expression of A20, the deubiquitinase suppressing inflammatory NF-κB signaling. DREAM-deficient (Dream−/−) mice displayed persistent and unchecked A20 expression in response to endotoxin. DREAM functioned by transcriptionally repressing A20 through binding to downstream regulatory elements (DREs). In contrast, USF1 binding to the DRE-associated E-box domain activated A20 expression in response to inflammatory stimuli. These studies define the critical opposing functions of DREAM and USF1 in inhibiting and inducing A20 expression, respectively, and thereby the strength of NF-κB signaling. Targeting of DREAM to induce USF1-mediated A20 expression is therefore a potential anti-inflammatory strategy in diseases such as acute lung injury associated with unconstrained NF-κB activity.

The terrorist attacks of September 11, 2001, were traumatic for people living throughout the United States. It has been suggested that people living far from the attacks experienced increased stress because of their exposure to the terrorist events via the media, particularly via television. Following a traumatic or stressful event, individuals may have dreams that reflect that experience. As part of a course on dreaming, individuals recorded their dreams both prior to and following the terrorist attacks of September 11, 2001. On September 12, these same individuals reported their activities and media exposure the previous day. Results revealed (a) changes in dream features following the attacks and (b) a strong relation between exposure to the events on television and changes in dream features after the attacks. Because of the study's within-subjects design, the results provide evidence for a direct association between television viewing and subsequent increases in stress and trauma.

Rapid Eye Movements (REMs) and visual dream recall in both congenitally blind and sighted subjects

2017-08-01

Our objective was to evaluate rapid eye movements (REMs) associated with visual dream recall in sighted subjects and congenital blind. During two consecutive nights polysomnographic recordings were performed at subjects home. REMs were detected by visual inspection on both EOG channels (EOG-H, EOG-V) and further classified as occurring isolated or in bursts. Dream recall was defined by the existence of a dream report. The two groups were compared using t-test and also the two-way ANOVA and a post-hoc Fisher test (for the features diagnosis (blind vs. sighted) and dream recall (yes or no) as a function of time). The average of REM awakenings per subject and the recall ability were identical in both groups. CB had a lower REM density than CS; the same applied to REM bursts and isolated eye movements. In the two-way ANOVA, REM bursts and REM density were significantly different for positive dream recall, mainly for the CB group and for diagnosis; furthermore for both features significant results were obtained for the interaction of time, recall and diagnosis; the interaction of recall and time was however, stronger. In line with previous findings the data show that blind have lower REMs density. However the ability of dream recall in congenitally blind and sighted controls is identical. In both groups visual dream recall is associated with an increase in REM bursts and density. REM bursts also show differences in the temporal profile. REM visual dream recall is associated with increased REMs activity.

The Los Alamos dynamic radiation environment assimilation model (DREAM) for space weather specification and forecasting

2008-01-01

The Dynamic Radiation Environment Assimilation Model (DREAM) was developed at Los Alamos National Laboratory to assess, quantify, and predict the hazards from the natural space environment and the anthropogenic environment produced by high altitude nuclear explosions (HANE). DREAM was initially developed as a basic research activity to understand and predict the dynamics of the Earth's Van Allen radiation belts. It uses Kalman filter techniques to assimilate data from space environment instruments with a physics-based model of the radiation belts. DREAM can assimilate data from a variety of types of instruments and data with various levels of resolution and fidelity bymore » assigning appropriate uncertainties to the observations. Data from any spacecraft orbit can be assimilated but DREAM was designed to function with as few as two spacecraft inputs: one from geosynchronous orbit and one from GPS orbit. With those inputs, DREAM can be used to predict the environment at any satellite in any orbit whether space environment data are available in those orbits or not. Even with very limited data input and relatively simple physics models, DREAM specifies the space environment in the radiation belts to a high level of accuracy. DREAM has been extensively tested and evaluated as we transition from research to operations. We report here on one set of test results in which we predict the environment in a highly-elliptical polar orbit. We also discuss long-duration reanalysis for spacecraft design, using DREAM for real-time operations, and prospects for 1-week forecasts of the radiation belt environment.« less

1993-02-01

Twenty-five women and twenty-one men undergoing divorce had three laboratory nights of sleep on two occasions 1 year apart. On the third night, dream reports were elicited from subjects for each period of rapid eye movement (REM) sleep. Three groups differing on dream "masochism" were compared on personality, sex role, and social adjustment. Women "masochistic" dreamers had significantly higher scores on a scale of negative aspects of traditional feminine sex role identity than men or women without such dreams. They also showed less improvement at followup and had more need for emotional support. Dream masochism may be a continuing cognitive characteristic that contributes to the vulnerability of women to major depression.

Manifest dream content as a possible predictor of suicidality.

PubMed

Glucksman, Myron L

2014-12-01

The prediction of suicidal intent remains a clinical problem. This presentation illustrates that a distinction may be made between the manifest dream reports of patients who are potentially or acutely suicidal and those who are not. A review of the literature reveals that the manifest dream reports of clinically depressed, non-suicidal individuals differ from those who are depressed and acutely suicidal. The former contain themes of loss, disappointment, rejection, helplessness, hopelessness, failure, and death. The latter contain themes of dying, death, destruction, and violence directed toward the dreamer or others, as well as hopelessness and helplessness. The author collected manifest dream reports from three clinically depressed, non-suicidal patients and three clinically depressed, potentially or acutely suicidal patients. There are apparent differences between the themes of manifest dream reports in the clinically depressed, non-suicidal patients and the clinically depressed, potentially or acutely suicidal patients. The former contain themes of death, loss, rejection, vulnerability, hopelessness, and helplessness. The latter contain themes of active harm or violence (specifically toward the dreamer), dying or being dead, aloneness, vulnerability, hopelessness, and helplessness. Clinical cases and corresponding manifest dream reports are presented. Although this is a preliminary study, it is possible that manifest dream content may be used as one of the predictors of suicidality, in conjunction with latent dream content, diagnosis, life circumstance, and clinical status.
