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.

Spotlight on dream recall: the ages of dreams

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

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.

Dissociative states in dreams and brain chaos: implications for creative awareness

Bob, Petr; Louchakova, Olga

2015-01-01

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.

Noack, Amélie

2010-11-01

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.

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

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.

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.

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.

Consciousness in dreams.

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

PubMed

Hill, Clara E; Knox, Sarah; Crook-Lyon, Rachel E; Hess, Shirley A; Miles, Joe; Spangler, Patricia T; Pudasaini, Sakar

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.

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.

Dreaming and insight

PubMed Central

Edwards, Christopher L.; Ruby, Perrine M.; Malinowski, Josie E.; Bennett, Paul D.; Blagrove, Mark T.

2013-01-01

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

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.

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.

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.

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.

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.

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

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.

Dreams and acting out.

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.

[Phenomenology of dreams].

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).

The Fundamentals of Using the Digital Micromirror Device (DMD(TM)) for Projection Display

Developed by Texas Instruments (TI) the digital micromirror device (DMD(tm)) is a quickly emerging and highly useful micro-electro-mechanical structures (MEMS) device. Using standard semiconductor fabrication technology, the DMD's simplicity in concept and design will provide advantageous solutions for many different applications. At the rudimentary level, the DMD is a precision, semiconductor light switch. In the initial commercial development of DMD technology, TI has concentrated on projection display and hardcopy. This paper will focus on how the DMD is used for projection display. Other application areas are being explored and evaluated to find appropriate and beneficial uses for the DMD.

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).

Characteristics and contents of dreams.

Schredl, Michael

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.

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.

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

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.

Minding the dream self: perspectives from the analysis of self-experience in dreams.

Can ancient art of memory (AAOM) principles explain the function of dreaming? The analysis of self-experience in dreams suggests that the answer is no: The phenomenal dream self lacks certain dimensions that are crucial for the efficacy of AAOM in wakefulness. However, the comparison between dreams and AAOM may be fruitful by suggesting new perspectives for the study of lucid dreaming as well an altered perspective on the efficacy of AAOM itself.

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

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.

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.

Bereavement dream? Successful antidepressant treatment for bereavement-related distressing dreams in patients with major depression.

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.

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

The dream pattern was unchanged in six patients and dreams disappeared in another who normally dreamed often. 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.

Metacognitive mechanisms underlying lucid dreaming.

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

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.

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.

The dream in contemporary psychiatry.

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.

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.

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.

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.

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.

Dream to Predict? REM Dreaming as Prospective Coding

PubMed Central

Llewellyn, Sue

2016-01-01

The dream as prediction seems inherently improbable. The bizarre occurrences in dreams never characterize everyday life. Dreams do not come true! But assuming that bizarreness negates expectations may rest on a misunderstanding of how the predictive brain works. In evolutionary terms, the ability to rapidly predict what sensory input implies—through expectations derived from discerning patterns in associated past experiences—would have enhanced fitness and survival. For example, food and water are essential for survival, associating past experiences (to identify location patterns) predicts where they can be found. Similarly, prediction may enable predator identification from what would have been only a fleeting and ambiguous stimulus—without prior expectations. To confront the many challenges associated with natural settings, visual perception is vital for humans (and most mammals) and often responses must be rapid. Predictive coding during wake may, therefore, be based on unconscious imagery so that visual perception is maintained and appropriate motor actions triggered quickly. Speed may also dictate the form of the imagery. Bizarreness, during REM dreaming, may result from a prospective code fusing phenomena with the same meaning—within a particular context. For example, if the context is possible predation, from the perspective of the prey two different predators can both mean the same (i.e., immediate danger) and require the same response (e.g., flight). Prospective coding may also prune redundancy from memories, to focus the image on the contextually-relevant elements only, thus, rendering the non-relevant phenomena indeterminate—another aspect of bizarreness. In sum, this paper offers an evolutionary take on REM dreaming as a form of prospective coding which identifies a probabilistic pattern in past events. This pattern is portrayed in an unconscious, associative, sensorimotor image which may support cognition in wake through being mobilized as a

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

Threat in dreams: an adaptation?

Malcolm-Smith, Susan; Solms, Mark; Turnbull, Oliver; Tredoux, Colin

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 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

Daydreams and nap dreams: Content comparisons.

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.

Registratiom of TM data to digital elevation models

NASA Technical Reports Server (NTRS)

1984-01-01

Several problems arise when attempting to register LANDSAT thematic mapper data to U.S. B Geological Survey digital elevation models (DEMs). The TM data are currently available only in a rotated variant of the Space Oblique Mercator (SOM) map projection. Geometric transforms are thus; required to access TM data in the geodetic coordinates used by the DEMs. Due to positional errors in the TM data, these transforms require some sort of external control. The spatial resolution of TM data exceeds that of the most commonly DEM data. Oversampling DEM data to TM resolution introduces systematic noise. Common terrain processing algorithms (e.g., close computation) compound this problem by acting as high-pass filters.

Reflections on the self state dream.

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.

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

Voss, Ursula; Holzmann, Romain; Tuin, Inka; Hobson, J. Allan

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.

1990-10-01

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.

Dreaming: a gateway to the unconscious?

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.

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.

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.

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.

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

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.

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.

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

2014-01-01

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 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.

This article demonstrates the use of a digital word search method designed to provide greater accuracy, objectivity, and speed in the study of dreams. A revised template of 40 word search categories, built into the website of the Sleep and Dream Database (SDDb), is applied to four "classic" sets of dreams: The male and female "Norm" dreams of Hall and Van de Castle (1966), the "Engine Man" dreams discussed by Hobson (1988), and the "Barb Sanders Baseline 250" dreams examined by Domhoff (2003). A word search analysis of these original dream reports shows that a digital approach can accurately identify many of the same distinctive patterns of content found by previous investigators using much more laborious and time-consuming methods. The results of this study emphasize the compatibility of word search technologies with traditional approaches to dream content analysis. Copyright © 2014 Elsevier Inc. All rights reserved.

Exploring the dreams of hospice workers.

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.

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.

Transcending the caesura: reverie, dreaming and counter-dreaming.

PubMed

Bergstein, Avner

2013-08-01

The author reflects about our capacity to get in touch with primitive, irrepresentable, seemingly unreachable parts of the Self and with the unrepressed unconscious. It is suggested that when the patient's dreaming comes to a halt, or encounters a caesura, the analyst dreams that which the patient cannot. Getting in touch with such primitive mental states and with the origin of the Self is aspired to, not so much for discovering historical truth or recovering unconscious content, as for generating motion between different parts of the psyche. The movement itself is what expands the mind and facilitates psychic growth. Bion's brave and daring notion of 'caesura', suggesting a link between mature emotions and thinking and intra-uterine life, serves as a model for bridging seemingly unbridgeable states of mind. Bion inspires us to 'dream' creatively, to let our minds roam freely, stressing the analyst's speculative imagination and intuition often bordering on hallucination. However, being on the seam between conscious and unconscious, dreaming subverts the psychic equilibrium and poses a threat of catastrophe as a result of the confusion it affords between the psychotic and the non-psychotic parts of the personality. Hence there is a tendency to try and evade it through a more saturated mode of thinking, often relying on external reality. The analyst's dreaming and intuition, perhaps a remnant of intra-uterine life, is elaborated as means of penetrating and transcending the caesura, thus facilitating patient and analyst to bear unbearable states of mind and the painful awareness of the unknowability of the emotional experience. This is illustrated clinically. Copyright © 2013 Institute of Psychoanalysis.

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.

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

Introduction. 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. Methods. 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. Results. 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. Conclusions. 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.

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.

[Neuropsychology of dreams].

PubMed

Tirapu-Ustarroz, J

2012-07-16

Dreams are a universal human experience and studying them from the point of view of neuroscience, consciousness, emotions and cognition is quite a challenge for researchers. Thus, dreams have been addressed from a number of different perspectives ranging from philosophy to clinical medicine, as well as psychiatry, psychology, artificial intelligence, neural network models, psychophysiology or neurobiology. The main models are grounded on the biological function of dreams, especially those based on processes involving the consolidation of memory and forgetting, and models of simulation. Similarly, current models are developed upon the neurobiology and the neuropsychology of the REM phases of sleep and how they are differentiated from wakefulness. Thus, neurobiologically speaking, dreams are related to the role of acetylcholine and, neuropsychologically, to the activation of the limbic and paralimbic regions, the activation of the basal ganglia, the activation of cortical areas with a specific modality (especially Brodmann's areas 19, 22 and 37) and the deactivation of the ventromedial, parietal and dorsolateral prefrontal cortex and posterior cingulate. Dreams can be considered a state of consciousness that is characterised by a reduced control over their content, visual images and activation of the memory, and which is mediated by motivational incentives and emotional salience.

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.

Dreaming scientists and scientific dreamers: Freud as a reader of French dream literature.

Carroy, Jacqueline

2006-03-01

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.

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.

[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.

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.

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

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.

DREAMING THE ANALYTIC SESSION: A CLINICAL ESSAY.

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.

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.

The genius of the dream.

Palombo, S R

1983-01-01

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.

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.

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.

[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.

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.

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.

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.

Design of the PET-MR system for head imaging of the DREAM Project

González, A. J.; Conde, P.; Hernández, L.; Herrero, V.; Moliner, L.; Monzó, J. M.; Orero, A.; Peiró, A.; Rodríguez-Álvarez, M. J.; Ros, A.; Sánchez, F.; Soriano, A.; Vidal, L. F.; Benlloch, J. M.

2013-02-01

In this paper we describe the overall design of a PET-MR system for head imaging within the framework of the DREAM Project as well as the first detector module tests. The PET system design consists of 4 rings of 16 detector modules each and it is expected to be integrated in a head dedicated radio frequency coil of an MR scanner. The PET modules are based on monolithic LYSO crystals coupled by means of optical devices to an array of 256 Silicon Photomultipliers. These types of crystals allow to preserve the scintillation light distribution and, thus, to recover the exact photon impact position with the proper characterization of such a distribution. Every module contains 4 Application Specific Integrated Circuits (ASICs) which return detailed information of several light statistical momenta. The preliminary tests carried out on this design and controlled by means of ASICs have shown promising results towards the suitability of hybrid PET-MR systems.

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.

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

PubMed

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.

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

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.

Bizarreness effect in dream recall.

PubMed

Cipolli, C; Bolzani, R; Cornoldi, C; De Beni, R; Fagioli, I

1993-02-01

This study aimed to ascertain a) whether morning reports of dream experience more frequently reproduce bizarre contents of night reports than nonbizarre ones and b) whether this effect depends on the rarity of bizarre contents in the dream or on their richer encoding in memory. Ten subjects were awakened in rapid eye movement (REM) sleep three times per night for 4 nonconsecutive nights and asked to report their previous dream experiences. In the morning they were asked to re-report those dreams. Two separate pairs of judges scored the reports: the former identified the parts in each report with bizarre events, characters or feelings and the latter parsed each report into content units using transformational grammar criteria. By combining the data of the two analyses, content units were classified as bizarre or nonbizarre and, according to whether present in both the night and corresponding morning reports, as semantically equivalent or nonequivalent. The proportion of bizarre contents common to night and morning reports was about twice that of nonbizarre contents and was positively correlated to the quantity of bizarre contents present in the night report. These findings support the view that bizarreness enhances recall of dream contents and that this memory advantage is determined by a richer encoding at the moment of dream generation. Such a view would seem to explain why dreams in everyday life, which are typically remembered after a rather long interval, appear more markedly bizarre than those recalled in the sleep laboratory.

In May 2013, the DREAM MagellanPlus Workshop was held in Brisighella (Italy). The initiative builds from recent activities by various research groups to identify potential sites to perform deep-sea scientific drilling in the Mediterranean Sea across the deep Messinian Salinity Crisis (MSC) sedimentary record. In this workshop three generations of scientists were gathered: those who participated in formulation of the deep desiccated model, through DSDP Leg 13 drilling in 1973; those who are actively involved in present-day MSC research; and the next generation (PhD students and young post-docs). The purpose of the workshop was to identify locations for multiple-site drilling (including riser-drilling) in the Mediterranean Sea that would contribute to solve the several open questions still existing about the causes, processes, timing and consequences at local and planetary scale of an outstanding case of natural environmental change in the recent Earth history: the Messinian Salinity Crisis in the Mediterranean Sea. The product of the workshop is the identification of the structure of an experimental design of site characterization, riser-less and riser drilling, sampling, measurements, and down-hole analyses that will be the core for at least one compelling and feasible multiple phase drilling proposal. Particular focus has been given to reviewing seismic site survey data available from different research groups at pan-Mediterranean basin scale, to the assessment of additional site survey activity including 3D seismics, and to ways of establishing firm links with oil and gas industry. The scientific community behind the DREAM initiative is willing to proceed with the submission to IODP of a Multi-phase Drilling Project including several drilling proposals addressing specific drilling objectives, all linked to the driving objectives of the MSC drilling and understanding . A series of critical drilling targets were identified to address the still open questions

Critique and cure: a dream of uniting psychoanalysis and philosophy.

PubMed

Webster, Jamieson

2013-06-01

Critical theory, whose aim was to historicize philosophy through integrating it with the social sciences, turned to psychoanalysis to find its way through an accounting of philosophy after the Second World War. Over 50 years after this initial project, the rift between philosophy and psychoanalysis has never been greater. If Jacques Lacan could be considered one of the few psychoanalysts to maintain and foster links to philosophical thought in the latter half of the 20th century, his work has sadly remained marginal in the clinical field throughout America and Europe. Both critical theory and Lacan remain skeptical of the direction taken by psychoanalysis after Freud. Reflecting on the history of these two disciplines, as well as through an examination of Theodor Adorno's posthumously published dream journal, critique and cure emerge as two dialectically intertwined themes that gain momentum in the dream of the unification of the philosophical and psychoanalytic projects.

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

Lucid dreaming verified by volitional communication during REM sleep.

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.

Dreams, katharsis and anxiety.

2013-06-01

Over the centuries, the importance and the nature of the relationship of "inside" and "outside" in human experience have shifted, with consequences for notions of mind and body. This paper begins with dreams and healing in the Asklepian tradition. It continues with Aristotle's notions of psuche and how these influenced his conception of katharsis and tragedy. Jumping then to the 17th century, we will consider Descartes' focus on dreams in his theories of thinking. Finally, we will turn explicitly to Freud's use of dreams in relation to his theories of anxiety, of psychic processes and of the Oedipus Complex.

The dream: a psychodynamically informative instrument.

Glucksman, M L

2001-01-01

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.

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.

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.

Walking dreams in congenital and acquired paraplegia.

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.

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.

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

PubMed

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.

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.

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.

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.

Drebing, C E; Gooden, W E; Drebing, S M; Van de Kemp, H; Malony, H N

1995-01-01

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.

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.

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.

Recurrent Dreams and Psychosocial Adjustment in Preteenaged Children

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

Dreaming and cognition in patients with frontotemporal dysfunction.

PubMed

Paiva, Teresa; Bugalho, Paulo; Bentes, Carla

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.

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.

Disturbed dreaming during the third trimester of pregnancy.

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.

The author analyzes the nature and typologies of dreams in Tertullianus' De anima and, briefly, in the work of Agostinus, two centuries later. What are made dreams of? 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?

Red balloon: approaching dreams as self-narratives.

2011-10-01

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.

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.

The content of recurrent dreams in young adolescents

Gauchat, Aline; Séguin, Jean R.; McSween-Cadieux, Esther; Zadra, Antonio

2015-01-01

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.

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.

Automatic gender detection of dream reports: A promising approach.

Wong, Christina; Amini, Reza; De Koninck, Joseph

2016-08-01

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.

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

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.

How bizarre? A pluralist approach to dream content.

PubMed

Rosen, Melanie G

2018-05-05

Are dreams bizarre, nonsensical experiences or real-world simulations? I introduce a pluralist approach to dream content that highlights the philosophical and empirical implications of treating dreaming as a highly varied experience that can be anywhere on a spectrum from truly bizarre and incoherent to wake-like and mundane. Here I discuss several explanations for why theorists disagree on whether dreams should be defined as primarily bizarre or convincing, real-world simulations. Rating scales can underestimate or overestimate bizarreness depending on the variables of the scale and interpretation of contextual factors. Although double blind analysis of dream reports is assumed to be the most accurate method of quantifying dream bizarreness, contextual factors can only be clarified by the dreamer themselves, since only they can judge whether an event would be bizarre in their own lives, however the dreamer might find elements bizarre after waking that they did not find unusual during the dream. Dreams can at times be so bizarre and incoherent that that they are difficult or impossible to report accurately, mundane and indistinguishable from waking life or anything in-between. Both bizarre and mundane dreams should be of great interest to philosophers of mind and cognitive scientists. Copyright © 2018 Elsevier Inc. All rights reserved.

Commercialization of Medium Voltage HTS Triax TM Cable Systems

The original project scope that was established in 2007 aimed to install a 1,700 meter (1.1 mile) medium voltage HTS Triax{TM} cable system into the utility grid in New Orleans, LA. In 2010, however, the utility partner withdrew from the project, so the 1,700 meter cable installation was cancelled and the scope of work was reduced. The work then concentrated on the specific barriers to commercialization of HTS cable technology. The modified scope included long-length HTS cable design and testing, high voltage factory test development, optimized cooling system development, and HTS cable life-cycle analysis. In 2012, Southwire again analyzed themore » market for HTS cables and deemed the near term market acceptance to be low. The scope of work was further reduced to the completion of tasks already started and to testing of the existing HTS cable system in Columbus, OH. The work completed under the project included: • Long-length cable modeling and analysis • HTS wire evaluation and testing • Cable testing for AC losses • Optimized cooling system design • Life cycle testing of the HTS cable in Columbus, OH • Project management. The 200 meter long HTS Triax{TM} cable in Columbus, OH was incorporated into the project under the initial scope changes as a test bed for life cycle testing as well as the site for an optimized HTS cable cooling system. The Columbus cable utilizes the HTS TriaxTM design, so it provided an economical tool for these of the project tasks.« less

Living the Behavioral Dream.

2013-01-01

Most of us have had a workday where we left a bit frustrated about one thing or another and thought "if I was in charge, I know I could do it better." We dream of a better tomorrow where we tell our employer goodbye and become our own boss. Is that not the American Dream? We are told from early childhood that anything is possible and we can be anything we want to be if we just work hard. Somewhere between those naive childhood years and today we probably have come to realize these grand promises are more myths than truths and we become content with an approximation of this dream. To some individuals, however, approximations are not close enough.

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.

DREAM regulates BDNF-dependent spinal sensitization

PubMed Central

2010-01-01

Background The transcriptional repressor DREAM (downstream regulatory element antagonist modulator) controls the expression of prodynorphin and has been involved in the modulation of endogenous responses to pain. To investigate the role of DREAM in central mechanisms of pain sensitization, we used a line of transgenic mice (L1) overexpressing a Ca2+- and cAMP-insensitive DREAM mutant in spinal cord and dorsal root ganglia. Results L1 DREAM transgenic mice showed reduced expression in the spinal cord of several genes related to pain, including prodynorphin and BDNF (brain-derived neurotrophic factor) and a state of basal hyperalgesia without change in A-type currents. Peripheral inflammation produced enhancement of spinal reflexes and increased expression of BDNF in wild type but not in DREAM transgenic mice. The enhancement of the spinal reflexes was reproduced in vitro by persistent electrical stimulation of C-fibers in wild type but not in transgenic mice. Exposure to exogenous BDNF produced a long-term enhancement of dorsal root-ventral root responses in transgenic mice. Conclusions Our results indicate that endogenous BDNF is involved in spinal sensitization following inflammation and that blockade of BDNF induction in DREAM transgenic mice underlies the failure to develop spinal sensitization.

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.

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

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.

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

Dreams, Perception, and Creative Realization.

PubMed

Glaskin, Katie

2015-10-01

This article draws on the ethnography of Aboriginal Australia to argue that perceptual openness, extending from waking life into dreaming experience, provides an important cognitive framework for the apprehension of dreamt experience in these contexts. I argue that this perceptual openness is analogous to the "openness to experience" described as a personality trait that had been linked with dream recall frequency (among other things). An implication of identifying perceptual openness at a cultural rather than at an individual level is two-fold. It provides an example of the ways in which cultural differences affect perception, indicative of cognitive diversity; and, given the relationship between dreams and creativity suggested anecdotally and through research, a cultural orientation toward perceptual openness is also likely to have implications for the realization of creativity that occurs through dreams. Such creativity though cannot be separated from the relational context in which such dreamt material is elaborated and understood. Copyright © 2015 Cognitive Science Society, Inc.

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.

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.

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.

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.

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.

The Dynamic Radiation Environment Assimilation Model (DREAM) is a 3-year effort sponsored by the US Department of Energy to provide global, retrospective, or real-time specification of the natural and potential nuclear radiation environments. 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

Dreaming and waking: similarities and differences revisited.

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.

Deceased loved ones in the dreams of mentally retarded adults.

Turner, J L; Graffam, J H

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.

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.

Dreaming woman: Image, place, and the aesthetics of exile.

PubMed

Greenspan, Rachel

2017-08-01

Looking closely at an Argentine dream interpretation column published in a popular women's magazine from 1948 to 1951, this article examines the role of the dream image in shaping psychoanalytic discourse on femininity and national identity. The column, 'Psychoanalysis Will Help You,' emerged during Juan Domingo Perón's first presidency, featuring verbal interpretations written under the pen name 'Richard Rest,' as well as surreal photomontages by Grete Stern, a German-born, Bauhaus-trained photographer living in exile since 1936. While the column's Jungian text encourages readers' adaptation to the external reality of their social situation, Stern's droll images emphasize the disjuncture between subject and environment, exposing tensions between the experience of exile and the Peronist mission to consolidate an Argentine national identity. Experimenting formally with European avant-garde techniques, Stern presents femininity and nation as conflictive imaginary configurations. This theme resurfaces at the 2013 Venice Biennale, where Nicola Costantino's multimedia installation Eva - Argentina: A Contemporary Metaphor was exhibited alongside Carl Jung's Red Book. Formal contrasts between Stern's use of photomontage, Costantino's projection technique, and Jung's theory of mandala symbolism indicate the divergent ways in which their artwork posits the therapeutic function of the dream image, as well as the role of aesthetic production in psychoanalytic care.

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

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."

Can we still dream when the mind is blank? Sleep and dream mentations in auto-activation deficit.

Bilateral damage to the basal ganglia causes auto-activation deficit, a neuropsychological syndrome characterized by striking apathy, with a loss of self-driven behaviour that is partially reversible with external stimulation. Some patients with auto-activation deficit also experience a mental emptiness, which is defined as an absence of any self-reported thoughts. We asked whether this deficit in spontaneous activation of mental processing may be reversed during REM sleep, when dreaming activity is potentially elicited by bottom-up brainstem stimulation on the cortex. Sleep and video monitoring over two nights and cognitive tests were performed on 13 patients with auto-activation deficit secondary to bilateral striato-pallidal lesions and 13 healthy subjects. Dream mentations were collected from home diaries and after forced awakenings in non-REM and REM sleep. The home diaries were blindly analysed for length, complexity and bizarreness. A mental blank during wakefulness was complete in six patients and partial in one patient. Four (31%) patients with auto-activation deficit (versus 92% of control subjects) reported mentations when awakened from REM sleep, even when they demonstrated a mental blank during the daytime (n = 2). However, the patients' dream reports were infrequent, short, devoid of any bizarre or emotional elements and tended to be less complex than the dream mentations of control subjects. The sleep duration, continuity and stages were similar between the groups, except for a striking absence of sleep spindles in 6 of 13 patients with auto-activation deficit, despite an intact thalamus. The presence of spontaneous dreams in REM sleep in the absence of thoughts during wakefulness in patients with auto-activation deficit supports the idea that simple dream imagery is generated by brainstem stimulation and is sent to the sensory cortex. However, the lack of complexity in these dream mentations suggests that the full dreaming process (scenario

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.

Variety and intensity of emotions in nightmares and bad dreams.

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.

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

Cipolli, Carlo; Ferrara, Michele; De Gennaro, Luigi; Plazzi, Giuseppe

2017-10-01

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.

Dreams as a source of supernatural agent concepts

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

Complex dream-enacting behavior in sleepwalking.

PubMed

Pillmann, Frank

2009-02-01

Currently, dream-enacting behaviors are viewed as occurring typically in association with a REM-sleep behavior disorder. In some cases, dream-like mentation is found also in non-REM parasomnia. We report a case of complex and dramatic sleepwalking behavior in a 26-year-old adult male who tied his 4-month-old daughter to the clothesline in the attic of his house. The explanation of this seemingly senseless behavior, which was related to psychosocial stressors, was found in a detailed dream-like mentation that was reported by the patient. At the same time, an organic factor, namely, a worsening of the patient's asthma, was identified as the cause of an increased fragmentation of sleep. In some cases of non-REM parasomnia, detailed dream-like mentation may act as a bridge between psychosocial stressors and the specific parasomnic behavior.

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

Dreams and Nightmares in Personality Disorders.

2016-02-01

Although the relationship between dreaming and psychopathology has been studied quite extensively, research on dreaming in patients with personality disorders has been very scarce. In patients with borderline personality disorder, negatively toned dreams and heightened nightmare frequency have been found-characteristics not determined by co-morbid depression or posttraumatic stress disorder. The review includes suggestions for future studies as the existing results clearly indicate that this line of research is most interesting. Lastly, clinical recommendations especially regarding the treatment of the often found co-morbid nightmare disorder will be given.

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

PubMed

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.

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.

Nightmare and Abnormal Dreams: Rare Side Effects of Metformin?

PubMed Central

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

Induction of lucid dreams: a systematic review of evidence.

PubMed

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

2012-09-01

In lucid dreams the dreamer is aware of dreaming and often able to influence the ongoing dream content. Lucid dreaming is a learnable skill and a variety of techniques is suggested for lucid dreaming induction. This systematic review evaluated the evidence for the effectiveness of induction techniques. A comprehensive literature search was carried out in biomedical databases and specific resources. Thirty-five studies were included in the analysis (11 sleep laboratory and 24 field studies), of which 26 employed cognitive techniques, 11 external stimulation and one drug application. The methodological quality of the included studies was relatively low. None of the induction techniques were verified to induce lucid dreams reliably and consistently, although some of them look promising. On the basis of the reviewed studies, a taxonomy of lucid dream induction methods is presented. Several methodological issues are discussed and further directions for future studies are proposed.

Dreaming and the brain: from phenomenology to neurophysiology

2009-01-01

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.

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 as space, time and emotion

PubMed Central

Totlis, Athanasios

2011-01-01

Human beings, like all living organisms, use energy ceaselessly with whatever they do. Nothing at all happens without spending some energy, not even a glance or a dream. The Author proposes that dreams happen automatically in sleep to help us release unresolved frustration energy and emotional dilemmas left over from the day before. Energy administration is the common denominator behind the manifold workings of dreams, as it is behind all operations of our consciousness in daytime, and this is far more important than one might at first suspect. In summary, if in waking reality the day prior to a dream, a specific sensory composition (a perception or picture) frustrates our mind such that the mind is unable or unwilling to accept this sensory composition, it forms and traps within us an emotional energy charge that lingers inside till that same night when the dream uses it in order to energize from memory analogous sensory components that form a spatiotemporally similar overall representational composition of the daytime waking event. This ends up as the dream we may remember the next day. For example, if in a real event yesterday a red apple between two green apples were in front of us and for some reason we were unable or unwilling to see and accept this perception, in a dream the next time we sleep, we may see promptly a red peach between two green peaches, which will be energized temporarily from our memory to serve the need of our psyche to represent the unprocessed emotion(s) and balance the tensions inside us. The dream always produces more acceptable symbolic perceptions for us to see or sense, and in doing so uses and releases at the same time the unacknowledged emotional energy inside us pending since yesterday's event.

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

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.

Dream content and intrusive thoughts in Obsessive-Compulsive Disorder.

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.

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.

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.

PNL is a Department of Energy (DOE) national laboratory operted by Battelle Memorial Institute at its Pacific Northwest Laboratories in Richland, Washington. The objective of this investigation is to evaluate LANDSAT's thematic mapper (TM) data quality and utility characteristics from an energy research and technological perspective. Of main interest is the extent to which repetitive TM data might support DOE efforts relating to siting, developing, and monitoring energy-related facilities, and to basic geoscientific research. The investigation utilizes existing staff and facility capabilities, and ongoing programmatic activities at PNL and other DOE national laboratories to cooperatively assess the potential usefulness of the improved experimental TM data. The investigation involves: (1) both LANDSAT 4 and 5 TM data, (2) qualitative and quantitative use consideration, and 3) NASA P (corrected) and A (uncorrected) CCT analysis for a variety of sites of DOE interest. Initial results were presented at the LANDSAT Investigator's Workshops and at specialized LANDSAT TM sessions at various conferences.

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.

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.

Dream recall frequency by socioeconomic status of Chinese students.

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.

Tickle me, I think I might be dreaming! Sensory attenuation, self-other distinction, and predictive processing in lucid dreams

2014-01-01

The contrast between self- and other-produced tickles, as a special case of sensory attenuation for self-produced actions, has long been a target of empirical research. While in standard wake states it is nearly impossible to tickle oneself, there are interesting exceptions. Notably, participants awakened from REM (rapid eye movement-) sleep dreams are able to tickle themselves. So far, however, the question of whether it is possible to tickle oneself and be tickled by another in the dream state has not been investigated empirically or addressed from a theoretical perspective. Here, we report the results of an explorative web-based study in which participants were asked to rate their sensations during self-tickling and being tickled during wakefulness, imagination, and lucid dreaming. Our results, though highly preliminary, indicate that in the special case of lucid control dreams, the difference between self-tickling and being tickled by another is obliterated, with both self- and other produced tickles receiving similar ratings as self-tickling during wakefulness. This leads us to the speculative conclusion that in lucid control dreams, sensory attenuation for self-produced tickles spreads to those produced by non-self dream characters. These preliminary results provide the backdrop for a more general theoretical and metatheoretical discussion of tickling in lucid dreams in a predictive processing framework. We argue that the primary value of our study lies not so much in our results, which are subject to important limitations, but rather in the fact that they enable a new theoretical perspective on the relationship between sensory attenuation, the self-other distinction and agency, as well as suggest new questions for future research. In particular, the example of tickling during lucid dreaming raises the question of whether sensory attenuation and the self-other distinction can be simulated largely independently of external sensory input.

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.

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.

Improvement of darts performance following lucid dream practice depends on the number of distractions while rehearsing within the dream - a sleep laboratory pilot study.

Schädlich, Melanie; Erlacher, Daniel; Schredl, Michael

2017-12-01

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.

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

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

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.

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.

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

Dream-Enacting Behaviors in a Normal Population

Study Objectives: Determine the prevalence and gender distributions of behaviors enacted during dreaming (“dream-enacting [DE] behaviors”) in a normal population; the independence of such behaviors from other parasomnias; and the influence of different question wordings, socially desirable responding and personality on prevalence. Design: 3-group questionnaire study Setting: University classrooms Participants: Three undergraduate samples (Ns = 443, 201, 496; mean ages = 19.9 ± 3.2 y; 20.1 ± 3.4 y; 19.1 ± 1.6 y) Interventions: N/A Measurements and Results: Subjects completed questionnaires about DE behaviors and Social Desirability. Study 1 employed a nonspecific question about the behaviors, Study 2 employed the same question with examples, and Study 3 employed 7 questions describing specific behavior subtypes (speaking, crying, smiling/laughing, fear, anger, movement, sexual arousal). Somnambulism, somniloquy, nightmares, dream recall, alexithymia, and absorption were also assessed. Factor analyses were conducted to determine relationships among DE behaviors and their independence from other parasomnias. Prevalence increased with increasing question specificity (35.9%, 76.7%, and 98.2% for the 3 samples). No gender difference obtained for the nonspecific question, but robust differences occurred for more specific questions. Females reported more speaking, crying, fear and smiling/laughing than did males; males reported more sexual arousal. When controlling other parasomnias and dream recall frequency, these differences persisted. Factor solutions revealed that DE behaviors were independent of other parasomnias and of dream recall frequency, except for an association between dream-talking and somniloquy. Sexual arousal was related only to age. Behaviors were independent of alexithymia but moderately related to absorption. Conclusions: Dream-enacting behaviors are prevalent in healthy subjects and sensitive to question wording but not social desirability

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.

Amygdala and hippocampus volumetry and diffusivity in relation to dreaming.

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.

Loss of the Mammalian DREAM Complex Deregulates Chondrocyte Proliferation

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

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.

Manifest Dream Content as a Predictor of Suicidality.

PubMed

Glucksman, Myron L; Kramer, Milton

2017-01-01

A number of behavioral, social, biological, and cultural factors are associated with suicide. However, the ability to predict an imminent suicide attempt remains problematic. Prior studies indicate that the manifest dream content of depressed, non-suicidal patients differs from that of depressed, suicidal patients. The dream imagery of depressed, suicidal patients contains themes of death, dying, violence, and departure. The dream imagery of depressed, non-suicidal patients contains themes of rejection, helplessness, hopelessness, humiliation, failure, and loss. In the present study, the dream reports of 52 depressed patients were collected and rated for various themes. Patients were divided into three groups: Depressed and non-suicidal; Depressed, with suicidal ideation; Depressed, with suicidal ideation and/or attempt(s). Themes of death and/or dying, and to a lesser extent, themes of violence, injury, and/or murder occurred with greater frequency in the dream reports of depressed patients with suicidal ideation and/or attempts, than in the dream reports of depressed patients without suicidal ideation or behavior. These observations correspond with the prevailing psychodynamic explanation of suicide; namely, that it is a murderous attack on the self that is identified with hated internalized objects.

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.

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.

PubMed

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.

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.

The role of dreaming in childhood and in adulthood are still equally enigmatic fields yet to be fully explored. However, while there is a consensus at least about the typical content and formal characteristics of adult dream reports, these features are still a matter of debate in the case of young children. Longitudinal developmental laboratory studies concluded that preschoolers' dreams usually depict static images about mostly animals and body states of the dreamer but they basically lack the active representation of the self, human characters, social interactions, dream emotions and motion imagery. Due to methodological arguments these results became the reference points in the literature of developmental dream research, in spite of the significantly different results of numerous recent and relevant studies using extra-laboratory settings. This study aims to establish a methodologically well-controlled and valid way to collect children's dreams for a representative period of time in a familiar home setting to serve as a comparison to the laboratory method. Pre trained parents acted as interviewers in the course of a 6 week-period of dream collection upon morning awakenings. Our results suggest that even preschoolers are likely to represent their own self in an active role (70%) in their mostly kinematic (82%) dream narratives. Their dream reports contain more human, than animal characters (70 and 7% of all dream characters respectively), and social interactions, self-initiated actions, and emotions are usual part of these dreams. These results are rather similar to those of recent extra-laboratory studies, suggesting that methodological issues may strongly interfere with research outcomes especially in the case of preschoolers' dream narratives. We suggest that nighttime awakenings in the laboratory setting could be crucial in understanding the contradictory results of dream studies in case of young children. PMID:25983708

2007-01-01

Study objectives: Evaluate the prevalence and phenomenology of dream-associated behaviors affecting pregnant and postpartum mothers. Episodes consist of anxious dreams and nightmares about the new infant that are accompanied by complex behaviors (motor activity, speaking, expressing emotion). Design: Three-group design (postpartum, pregnant, null gravida), self-report, and repeated measures. Setting: Pregnancy and postpartum groups: completion of questionnaires in hospital room within 48 hours of giving birth and home telephone interviews; null gravida group: completion of questionnaires and interview in person or by telephone. Participants: Two hundred seventy-three women in 3 groups: postpartum: n = 202 (mean age = 29.7 ± 4.94 years; 95 primiparas, 107 multiparas); pregnant: n = 50 (mean age = 31.1 ± 5.44 years); null gravida: n = 21 (mean age = 28.5 ± 6.34 years). Interventions: Subjects completed questionnaires about pregnancy and birth factors, personality, and sleep and participated in interviews concerning the prevalence of recent infant dreams and nightmares, associated behaviors, anxiety, depression, and other psychopathologic factors. Measurements and Results: Most women in all groups recalled dreams (88%-91%). Postpartum and pregnant women recalled infant dreams and nightmares with equal prevalence, but more postpartum women reported they contained anxiety (75%) and the infant in peril (73%) than did pregnant women (59%, P < 0.05 and 42%, P < 0.0001). More postpartum (63%) than pregnant (40%) women reported dream-associated behaviors (P < 0.01), but neither group differed from null gravida women (56%). This was due to different distributions over groups of the behavior subtypes. Motor activity was present in twice as many postpartum (57%) as pregnant (24%) or null gravida (25%) women (all P < 0.0001). Expressing emotion was more prevalent among null gravida (56%) than postpartum women (27%) (P < 0.05) but was not different from pregnant women (37

The human population displays wide variety in demographic history, ancestry, content of DNA derived from hominins or ancient populations, adaptation, traits, copy number variation, drug response, and more. These polymorphisms are of broad interest to population geneticists, forensics investigators, and medical professionals. Historically, much of that knowledge was gained from population survey projects. Although many commercial arrays exist for genome-wide single-nucleotide polymorphism genotyping, their design specifications are limited and they do not allow a full exploration of biodiversity. We thereby aimed to design the Diversity of REcent and Ancient huMan (DREAM)-an all-inclusive microarray that would allow both identification of known associations and exploration of standing questions in genetic anthropology, forensics, and personalized medicine. DREAM includes probes to interrogate ancestry informative markers obtained from over 450 human populations, over 200 ancient genomes, and 10 archaic hominins. DREAM can identify 94% and 61% of all known Y and mitochondrial haplogroups, respectively, and was vetted to avoid interrogation of clinically relevant markers. To demonstrate its capabilities, we compared its FST distributions with those of the 1000 Genomes Project and commercial arrays. Although all arrays yielded similarly shaped (inverse J) FST distributions, DREAM's autosomal and X-chromosomal distributions had the highest mean FST, attesting to its ability to discern subpopulations. DREAM performances are further illustrated in biogeographical, identical by descent, and copy number variation analyses. In summary, with approximately 800,000 markers spanning nearly 2,000 genes, DREAM is a useful tool for genetic anthropology, forensic, and personalized medicine studies. © The Author(s) 2017.

There have been reports and claims in the psychotherapeutic literature that the consideration of recent dreams can result in personal realizations and insight. There is theoretical support for these claims from work on rapid eye movement (REM) sleep having a function of the consolidation of emotional memories and the creative formation of connections between new and older memories. To investigate these claims, 11 participants (10 females, one male) reported and considered a recent home dream in a dream discussion group that following the “Appreciating dreams” method of Montague Ullman. The group ran 11 times, each participant attending and participating once. A further nine participants (seven females, two males) reported and considered a recent home dream in a group that followed the “Listening to the dreamer” method of Michael Schredl. The two studies each had a control condition where the participant also reported a recent event, the consideration of which followed the same technique as was followed for the dream report. Outcomes of the discussions were assessed by the participants on the Gains from Dream Interpretation (GDI) scale, and on its counterpart, the Gains from Event Interpretation scale. High ratings on the GDI experiential-insight subscale were reported for both methods, when applied to dreams, and for the Ullman method Exploration-Insight ratings for the dream condition were significantly higher than for the control event condition. In the Ullman method, self-assessment of personal insight due to consideration of dream content was also significantly higher than for the event consideration condition. The findings support the view that benefits can be obtained from the consideration of dream content, in terms of identifying the waking life sources of dream content, and because personal insight may also occur. To investigate the mechanisms for the findings, the studies should be repeated with REM and non-REM dream reports, hypothesizing greater

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

PubMed

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.

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

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.

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.

Study Objectives: We investigated a generally unappreciated feature of the sleep disorder narcolepsy, in which patients mistake the memory of a dream for a real experience and form sustained delusions about significant events. Design: We interviewed patients with narcolepsy and healthy controls to establish the prevalence of this complaint and identify its predictors. Setting: Academic medical centers in Boston, Massachusetts and Leiden, The Netherlands. Participants: Patients (n = 46) with a diagnosis of narcolepsy with cataplexy, and age-matched healthy healthy controls (n = 41). Interventions: N/A. Measurements and Results: “Dream delusions” were surprisingly common in narcolepsy and were often striking in their severity. As opposed to fleeting hypnagogic and hypnopompic hallucinations of the sleep/wake transition, dream delusions were false memories induced by the experience of a vivid dream, which led to false beliefs that could persist for days or weeks. Conclusions: The delusional confusion of dreamed events with reality is a prominent feature of narcolepsy, and suggests the possibility of source memory deficits in this disorder that have not yet been fully characterized.

Although low quality of sleep has been reported in kidney transplant patients with functioning allografts, there are no previous studies investigating the dreams of these patients. We aimed to investigate the differences in dream anxiety level between renal transplant patients and healthy control subjects. We also planned to compare depression and anxiety symptoms, sleep quality and sleepiness level between these two groups. Twenty-two living-donor renal transplant recipients followed at an outpatient nephrology clinic and 22 healthy controls were enrolled in this observational cross-sectional study. Sociodemographic Data Collection Form, and the Van Dream Anxiety Scale (VDAS), the Pittsburg Sleep Quality Index (PSQI), the Insomnia Severity Index (ISI), Beck Depression and Anxiety Inventories were used for the assessment of the necessary features. Hemoglobin (Hb), blood urea nitrogen (BUN), creatinine (Cr) and glucose levels were measured. There were no significant differences between the groups in terms of dream anxiety (p = 0.45), depression (p = 0.76), sleep quality (p = 0.8), insomnia severity (p = 0.08) and Hb (p = 0.11) and glucose levels (p = 0.14). Although, BUN (p = 0.00) and creatinine (p = 0.00) levels differed significantly between the two groups, both parameters were found to be within their normal range. In our study, chronic renal failure patients with a successful kidney transplant were found to be able to completely return to normal in terms of metabolic parameters, sleep quality and mood. Similar levels of dream anxiety are also consistent with these findings.

Graph analysis of dream reports is especially informative about psychosis

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. PMID:24424108

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

Phelps, Andrea J; Forbes, David; Hopwood, Malcolm; Creamer, Mark

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.

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

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.

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

PubMed

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.

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).

Studying the interpretation of dreams in the company of analytic candidates.

Levy, Joshua

2009-08-01

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.

"Dreaming, in any case, remains a mental activity and not a physiological process, even though it springs from this process". This sentence of Mauro Mancia encapsulates the entire significance of his studies on sleeping/dreaming. A totality of observations and reflections grounded in neurophysiology and psychoanalysis which led him to study and to "see" the two faces of a problem that has engaged man's attention since the remotest antiquity. Mancia has thus given us the resources to see the dream-and not only the dream-with the marvelled eye of the artist who seeks and finds a sense in things and at the same time with the cold eye of the scientist who demands of things only their how and wherefore.

A systematic analysis of energy transfer processes in crystals of YAG doped with varying concentrations of Cr and Tm is described. Both spectral measurements and measurements of the temporal response to pulsed excitation are used to give independent determinations of the microscopic interaction parameter for Cr to Tm transfer. The different factors in influencing the temperature dependence of the Cr to Tm transfer are discussed. The dependence of the Tm cross-relaxation rate on Tm concentration is determined.

Coping with stress: dream interpretation in the Mapuche family.

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.

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.

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.

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.

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.

On the validity of Freud's dream interpretations.

PubMed

Michael, Michael

2008-03-01

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.

Dreams and Psychedelics: Neurophenomenological Comparison and Therapeutic Implications.

Kraehenmann, Rainer

2017-01-01

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,Ndimethyltryptamine), 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. Research literature related to psychedelics and dreaming is reviewed, and these two states of consciousness are systematically compared. Relevant conclusions with regard to psychedelicassisted therapy will be provided. 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. 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.

Berrou, Antoine; Collett, Oliver J P; Morris, Daniel; Esser, M J Daniel

2018-04-16

We report on Tm:YLF and Tm:LLF slab lasers (1.5 x 11 x 20 mm 3 ) end pumped from one end with a high-brightness 792 nm laser diode stack. These two lasers are compared under identical pump conditions in continuous-wave regime. A stronger negative thermal lens in Tm:LLF than in Tm:YLF is highlighted, making it more difficult to operate the Tm:LLF laser under stable lasing conditions. In a configuration where the high reflectivity cavity mirror has a radius of curvature of r = 150 mm, the Tm:YLF (Tm:LLF) laser produces a maximum output power of 150 W (143 W) for 428 W of incident pump power (respectively). For a second cavity configuration where the high reflectivity cavity mirror has a radius of curvature of r = 500 mm, the Tm:YLF laser produces a maximum output power of 164 W for 412 W of incident pump power and a 57% slope efficiency with respect to the absorbed pump power. The emitted wavelength of these two lasers are measured as a function of the output coupler reflectivity and it shows that Tm:LLF laser emits at a longer wavelength than Tm:YLF.

Psychosis and the Control of Lucid Dreaming.

Mota, Natália B; Resende, Adara; Mota-Rolim, Sérgio A; Copelli, Mauro; Ribeiro, Sidarta

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.

Psychosis and the Control of Lucid Dreaming

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.

The present study investigated the relationship between the time required for specific tasks (counting and performing squats) in lucid dreams and in the waking state. 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.

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.

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.

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.

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.

Cavallotti, Simone; Castelnovo, Anna; Ranieri, Rebecca; D'agostino, Armando

2014-04-30

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.

[Dreams and sensoperception in epicurean theory].

PubMed

Pangas, Julio César

2007-01-01

In this article, we analyse the epicurean vision on sensoperception and dreams. This epicurean vision is known to us, specially, from the wrintings of his roman divulger, Titus Lucretius Caro in his work "On the nature of things" ("De rerum natura"), IV Chant. The epicureans adopted the materialistic conception of nature, based upon Democritus of Abdera atomistic theory and, in this way, they distinguished their theories on dreams from the general principles prevailing in the popular greco-roman litterature, as well as from the divinatory perception of oneirocritics like Artemidorus and also from the first steps of the physiological conception of dreams from philosophers as the presocratics and Aristotle. We end this article with some of the more interesting paragraphs from Chant IV of the work by Lucretius, regarding this subjet.

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.

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.

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.

Migraineurs brain is hyper-excitable and hypo-metabolic. Dreaming is a mental state characterized by hallucinatory features in which imagery, emotion, motor skills and memory are created de novo. To evaluate dreams in different kinds of headache. We included 219 controls; 148 migraineurs (66 with aura-MA, 82 without aura-MO); 45 tension type headache (TTH) patients. ICHD-II diagnostic criteria were used. Ad hoc questionnaire was used to evaluate oneiric activity. The Generalized Anxiety Disorder Questionnaire, and the Patient Health Questionnaire were administered to evaluate anxiety and mood. The prevalence of dreamers was similar in different groups. Frequency of visual and auditory dreams was not different between groups. Migraineurs, particularly MA, had an increased frequency of taste dreams (present in 19.6 % of controls, 40.9 % of MA, 23.2 % of MO, 11.1 % of TTH, p < 0.01), and of olfactory dreams (present in 20 % of controls, 36 % of MA, 35 % of MO and 20 % of TTH, p < 0.01). Anxiety and mood did not influence these results. The increased frequency of taste and olfactory dreams among migraineurs seems to be specific, possibly reflecting a particular sensitivity of gustative and olfactory brain structures, as suggested by osmofobia and nausea, typical of migraine. This may suggest the role of some cerebral structures, such as amygdala and hypothalamus, which are known to be involved in migraine mechanisms as well in the biology of sleep and dreaming.

Abstract The human population displays wide variety in demographic history, ancestry, content of DNA derived from hominins or ancient populations, adaptation, traits, copy number variation, drug response, and more. These polymorphisms are of broad interest to population geneticists, forensics investigators, and medical professionals. Historically, much of that knowledge was gained from population survey projects. Although many commercial arrays exist for genome-wide single-nucleotide polymorphism genotyping, their design specifications are limited and they do not allow a full exploration of biodiversity. We thereby aimed to design the Diversity of REcent and Ancient huMan (DREAM)—an all-inclusive microarray that would allow both identification of known associations and exploration of standing questions in genetic anthropology, forensics, and personalized medicine. DREAM includes probes to interrogate ancestry informative markers obtained from over 450 human populations, over 200 ancient genomes, and 10 archaic hominins. DREAM can identify 94% and 61% of all known Y and mitochondrial haplogroups, respectively, and was vetted to avoid interrogation of clinically relevant markers. To demonstrate its capabilities, we compared its FST distributions with those of the 1000 Genomes Project and commercial arrays. Although all arrays yielded similarly shaped (inverse J) FST distributions, DREAM’s autosomal and X-chromosomal distributions had the highest mean FST, attesting to its ability to discern subpopulations. DREAM performances are further illustrated in biogeographical, identical by descent, and copy number variation analyses. In summary, with approximately 800,000 markers spanning nearly 2,000 genes, DREAM is a useful tool for genetic anthropology, forensic, and personalized medicine studies. PMID:29165562

The transcriptional repressor DREAM is involved in thyroid gene expression

2005-04-15

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

Effects of pyridoxine on dreaming: a preliminary study.

2002-02-01

The effect of pyridoxine (Vitamin B-6) on dreaming was investigated in a placebo, double-blind study to examine various claims that Vitamin B-6 increases dream vividness or the ability to recall dreams. 12 college students participated in all three treatment conditions, each of which involved ingesting either 100 mg B-6, 250 mg B-6, or a placebo prior to bedtime for a period of five consecutive days. The treatment conditions were completely counterbalanced and a two-day wash-out period occurred between the three five-day treatment blocks. Morning self-reports indicated a significant difference in dream-salience scores (this is a composite score containing measures on vividness, bizarreness, emotionality, and color) between the 250-mg condition and placebo over the first three days of each treatment. The data for dream salience suggests that Vitamin B-6 may act by increasing cortical arousal during periods of rapid eve movement (REM) sleep. An hypothesis is presented involving the role of B-6 in the conversion of tryptophan to serotonin. However, this first study needs to be replicated using the same procedures and also demonstrated in a sleep laboratory before the results can be considered certain.

The cross section of the 169Tm(n,3n)167Tm reaction has been measured from 17.5 to 21.5 MeV using activation technique. This energy region was chosen to resolve the two different trends of the previous (n,3n) cross section measurements on 169Tm. In addition, the branching ratio of the 207.8 keV γ-ray line stemming from electron capture of 167Tm was measured to be 0.419(16). The result of these measurements provide more accurate diagnostic estimation of the so called reaction-in-flight neutrons produced via the internal confinement fusion plasma in deuterium-tritium capsules at the National Ignition Facility.

Using dreams to assess clinical change during treatment.

PubMed

Glucksman, Myron L; Kramer, Milton

2004-01-01

This article describes several studies that examine the relationship between the manifest content of selected dreams reported by patients and their clinical progress during psychoanalytic and psychodynamically oriented treatment. There are a number of elements that dreaming and psychotherapy have in common: affect regulation; conflict resolution; problem-solving; self-awareness; mastery and adaptation. Four different studies examined the relationship between the manifest content of selected dreams and clinical progress during treatment. In each study, the ratings of manifest content and clinical progress by independent observers were rank-ordered and compared. In three of the four studies there was a significant correlation between the rankings of manifest content and the rankings of clinical progress. This finding suggests that the manifest content of dreams can be used as an independent variable to assess clinical progress during psychoanalytic and psychodynamically oriented treatment.

[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.

We have determined the magnetic structure of the intermetallic compound TmGa by high-resolution neutron powder diffraction and (169)Tm Mössbauer spectroscopy. This compound crystallizes in the orthorhombic (Cmcm) CrB-type structure and its magnetic structure is characterized by magnetic order of the Tm sublattice along the a-axis. The initial magnetic ordering occurs at 15(1) K and yields an incommensurate antiferromagnetic structure described by the propagation vector k1 = [0 0.275(2) 0]. At 12 K the dominant ferromagnetic ordering of the Tm sublattice along the a-axis develops in what appears to be a first-order transition. At 3 K the magnetic structure of TmGa is predominantly ferromagnetic but a weakened incommensurate component remains. The ferromagnetic Tm moment reaches 6.7(2) μB at 3 K and the amplitude of the remaining incommensurate component is 2.7(4) μB. The (169)Tm hyperfine magnetic field at 5 K is 631(1) T.

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.

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.

2008-01-01

Paradoxical sleep (PS or REM sleep) is traditionally a matter for neurophysiology, a science of the brain. Dream is associated with neuropsychology and sciences of the mind. The relationships between sleep and dream are better understood in the light of new methodologies in both domains, particularly those of basic neurosciences which elucidate the mechanisms underlying SP and functional imaging techniques. Data from these approaches are placed here in the perspective of rather old clinical observations in human cerebral lesions and in the phylogeny of vertebrates, in order to support a theory of dream. Dreams may be seen as a living marker of a cognitivo-emotional process, called here "eidictic process", involving posterior brain and limbic structures, keeping up during wakefulness, but subjected, at that time, to the leading role of a cognitivo-rational process, called here "thought process". The last one is of instrumental origin in human beings. It involves prefrontal cortices (executive tasks) and frontal/parietal cortices (attention) in the brain. Some clinical implications of the theory are illustrated.

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.

Models have become a routine research output over the past decade. They are used by many scientific disciplines in order to understand and analyses the processes and conditions within their domain of interest. This has resulted in a significant increase in scientific understanding and in a multitude of discipline specific models, modelling system software and workflows. There is now a growing realisation that to address the most pertinent questions of the age, such as climate change and the sustainable use of natural resources, we need to bringing together climate, ecological, hydrological, hydrogeological, geological and socio-economic models in order to provide the necessary framework to make truly informed decisions. At the British Geological Survey our vision is to provide scientists with the data, tools, techniques and support to address trans-disciplinary environmental questions impacting on human society. We hope to achieve this by being a leading member of an open community that will share data, applications and environmental models thus enabling collaboration and achieving sustainable solutions. The British Geological Survey has recently completed a scoping study with the aim of planning the implementation of the vision and preparing the organisation for the changes that are required to enable it to engage more effectively in trans-disciplinary modelling. This has resulted in the launch of a cross-cutting project call Data and Research for Environmental Applications and Models: The DREAM. The scoping study recognised that the investment and knowledge captured within the many existing scientific models represent a significant resource and not one that could be easily replicated in more centralised environmental modelling software. The only viable option in a ‘linked models’ approach which enables models to pass parameters between each other at runtime. This is perceived to be a pragmatic, achievable and cost-effective solution. This solution brings

Many of the nation's colleges and universities are not sure what the proposed DREAM Act would mean for their institutions--and a number of them are operating amid confusion in trying to serve undocumented students legally in light of the defeat of the measure in the Senate last year to pass the legislation. It would have allowed some immigrants…

How we remember the stuff that dreams are made of: neurobiological approaches to the brain mechanisms of dream recall.

De Gennaro, Luigi; Marzano, Cristina; Cipolli, Carlo; Ferrara, Michele

Intrinsic and historical weaknesses delayed the spread of a sound neurobiological investigation on dreaming. Nevertheless, recent independent findings confirm the hypothesis that the neurophysiological mechanisms of encoding and recall of episodic memories are largely comparable across wakefulness and sleep. Brain lesion and neuroimaging studies converge in indicating that temporo-parieto-occipital junction and ventromesial prefrontal cortex play a crucial role in dream recall. Morphoanatomical measurements disclose some direct relations between volumetric and ultrastructural measures of the hippocampus-amygdala on the one hand, and some specific qualitative features of dreaming on the other. Intracranial recordings of epileptic patients also provide support for the notion that hippocampal nuclei mediate memory formation during sleep as well as in wakefulness. Finally, surface EEG studies showed that sleep cortical oscillations associated to a successful dream recall are the same involved in encoding and recall of episodic memories during wakefulness. Although preliminary, these converging pieces of evidence strengthen the general view that the neurophysiological mechanisms underlying episodic/declarative memory formation may be the same across different states of consciousness.

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.

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

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.

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.

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.

Sierra Nevada Corporation’s Dream Chaser completed an important step toward orbital flight with a successful captive carry test at NASA’s Armstrong Flight Research Center in California, located on Edwards Air Force Base. A helicopter successfully carried a Dream Chaser test article, which has the same specifications as a flight-ready spacecraft, to the same altitude and flight conditions of an upcoming free flight test. The Dream Chaser is a lifting-body, winged spacecraft that will fly back to Earth in a manner similar to NASA’s space shuttles. The successful captive carry test clears the way for a free flight test of the spacecraft later this year in which the uncrewed Dream Chaser will be released to glide on its own and land.

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

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).

Viktor Von Weizsäcker's paper "Dreams in so-called endogenic Magersucht (anorexia," first published in the Deutsche Medizinische Wochenschrift in 1937 (translation in M. Kaufman & M. Heiman [1964]. Evolution of psychosomatic concepts: Anorexia nervosa: A paradigm (pp. 181-197), New York: International Universities Press, has been described as a noteworthy and historically important contribution to the recognition of anorexia nervosa as a psychosomatic illness. Von Weizsäcker analyzed the dreams of patients he was treating for "endogenous anorexia" (magersucht). He claimed that in the bulimic phase his patients experienced nightmares dealing with themes of death, but that in the anorectic phases of restricted eating more pleasant dreams dealt with themes of blissful contentment. The authors draw current attention to his work as another early example of the treatment of the theme of death and death symbolism in the literature on eating disorders, and suggest some reappraisal of von Weizsäcker's interpretations of his own material.

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.

The Women's Health Clinic (WHC) at Mayo Clinic in Rochester, Minnesota, has provided consultative care to women with menopausal and sexual health concerns since 2005. Clinical information on the 8688 women seen in the WHC through May 2017 who gave consent for the use of their medical records in research is contained in the Data Registry on Experiences of Aging, Menopause, and Sexuality (DREAMS). Initially, DREAMS was created to improve the clinical care of women, but it has become a valuable research tool. About 25% of the DREAMS women have been seen in the WHC 2 or more times, allowing for passive longitudinal follow-up. Additionally, about 25% of the DREAMS women live in the 27-county region included in the expanded Rochester Epidemiology Project medical records linkage system, providing additional information on those women. The cohort has been used to investigate associations between: caffeine intake and vasomotor symptom bother; recent abuse (physical, sexual, verbal, and emotional) and menopausal symptoms; specific menopausal symptoms and self-reported view of menopause; and obstructive sleep apnea risk and vasomotor symptom severity and the experience of vasomotor symptoms in women older than 60 years. A study nearing completion describes a clinical series of over 3500 women presenting for sexual health consultation by sexual function domain and by decade of life. Other studies under way are determining correlates with sexual health and dysfunction. Planned studies will investigate associations between the experience with menopause and the risk of disease.

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

Alessandria, Maria; Vetrugno, Roberto; Cortelli, Pietro; Montagna, Pasquale

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.

Dreaming and Offline Memory Consolidation

PubMed Central

Wamsley, Erin J.

2015-01-01

Converging evidence suggests that dreaming is influenced by the consolidation of memory during sleep. Following encoding, recently formed memory traces are gradually stabilized and reorganized into a more permanent form of long-term storage. Sleep provides an optimal neurophysiological state to facilitate this process, allowing memory networks to be repeatedly reactivated in the absence of new sensory input. The process of memory reactivation and consolidation in the sleeping brain appears to influence conscious experience during sleep, contributing to dream content recalled on awakening. This article outlines several lines of evidence in support of this hypothesis, and responds to some common objections. PMID:24477388

An Attempt at Matching Waking Events Into Dream Reports by Independent Judges

PubMed Central

Wang, Jia Xi; Shen, He Yong

2018-01-01

Correlations between memories and dreaming has typically been studied by linking conscious experiences and dream reports, which has illustrated that dreaming reflects waking life events, thoughts, and emotions. As some research suggests that sleep has a function of memory consolidation, and dreams reflect this, researching this relationship further may uncover more useful insights. However, most related research has been conducted using the self-report method which asks participants to judge the relationship between their own conscious experiences and dreams. This method may cause errors when the research purpose is to make comparisons between different groups, because individual differences cannot be balanced out when the results are compared among groups. Based on a knowledge of metaphors and symbols, we developed two operationalized definitions for independent judges to match conscious experiences and dreams, the descriptive incorporation and the metaphorical incorporation, and tested their reliability for the matching purpose. Two independent judges were asked to complete a linking task for 212 paired event-dreams. Results showed almost half dreams can be matched by independent judges, and the independent-judge method could provide similar proportions for the linking task, when compared with the self-report method.

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.

We report a quality effects meta-analysis on studies from the period 1966-2016 measuring either (a) lucid dreaming prevalence (one or more lucid dreams in a lifetime); (b) frequent lucid dreaming (one or more lucid dreams in a month) or both. A quality effects meta-analysis allows for the minimisation of the influence of study methodological quality on overall model estimates. Following sensitivity analysis, a heterogeneous lucid dreaming prevalence data set of 34 studies yielded a mean estimate of 55%, 95% C. I. [49%, 62%] for which moderator analysis showed no systematic bias for suspected sources of variability. A heterogeneous lucid dreaming frequency data set of 25 studies yielded a mean estimate of 23%, 95% C. I. [20%, 25%], moderator analysis revealed no suspected sources of variability. These findings are consistent with earlier estimates of lucid dreaming prevalence and frequent lucid dreaming in the population but are based on more robust evidence. Copyright © 2016 Elsevier Inc.

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.

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.

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

William Domhoff, G; Schneider, Adam

2008-12-01

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.

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

Ontogenetic patterns in the dreams of women across the lifespan.

The present study supports and extends previous research on the developmental differences in women's dreams across the lifespan. The participants included 75 Canadian women in each of 5 age groups from adolescence to old age including 12-17, 18-24, 25-39, 40-64, and 65-85, totaling 375 women. One dream per participant was scored by two independent judges using the method of content analysis. Trend analysis was used to determine the ontogenetic pattern of the dream content categories. Results demonstrated significant ontogenetic decreases (linear trends) for female and familiar characters, activities, aggression, and friendliness. These patterns of dream imagery reflect the waking developmental patterns as proposed by social theories and recognized features of aging as postulated by the continuity hypothesis. Limitations and suggestions for future research including the examining of developmental patterns in the dreams of males are discussed. Copyright © 2015 Elsevier Inc. All rights reserved.

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.

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

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.

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.

The optical and scintillation properties of Tm3+-doped yttrium aluminum garnet Y3Al5O12 (YAG) and Tm3+-doped lutetium aluminum garnet Lu3Al5O12 (LuAG) are compared. The Tm3+-doped single crystals were grown by the micro-pulling down (μ-PD) technique. Both crystals demonstrated some emission peaks originated from 4f-4f forbidden transition of Tm3+ under 241Am alpha-ray excitation. The scintillation decay time of Tm3+-doped YAG was similar to that of LuAG. When irradiated by the gamma-rays from a 137Cs source, the relative scintillation light yields of Tm:YAG was 90% greater than that of Tm:LuAG.

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

Neurobiology and clinical implications of lucid dreaming.

PubMed

Mota-Rolim, Sérgio A; Araujo, John F

2013-11-01

Several lines of evidence converge to the idea that rapid eye movement sleep (REMS) is a good model to foster our understanding of psychosis. Both REMS and psychosis course with internally generated perceptions and lack of rational judgment, which is attributed to a hyperlimbic activity along with hypofrontality. Interestingly, some individuals can become aware of dreaming during REMS, a particular experience known as lucid dreaming (LD), whose neurobiological basis is still controversial. Since the frontal lobe plays a role in self-consciousness, working memory and attention, here we hypothesize that LD is associated with increased frontal activity during REMS. A possible way to test this hypothesis is to check whether transcranial magnetic or electric stimulation of the frontal region during REMS triggers LD. We further suggest that psychosis and LD are opposite phenomena: LD as a physiological awakening while dreaming due to frontal activity, and psychosis as a pathological intrusion of dream features during wake state due to hypofrontality. We further suggest that LD research may have three main clinical implications. First, LD could be important to the study of consciousness, including its pathologies and other altered states. Second, LD could be used as a therapy for recurrent nightmares, a common symptom of depression and post-traumatic stress disorder. Finally, LD may allow for motor imagery during dreaming with possible improvement of physical rehabilitation. In all, we believe that LD research may clarify multiple aspects of brain functioning in its physiological, altered and pathological states. Copyright © 2013 The Authors. Published by Elsevier Ltd..

The cross section for the 169Tm(n,3n) 167Tm reaction was measured from 17 to 22 MeV using quasimonoenergetic neutrons produced by the 2H(d,n) 3He reaction. This energy range was studied to resolve the discrepancy between previous (n,3n) cross-section measurements. In addition, the absolute γ-ray branching ratios following the electron-capture decay of 167Tm were measured. Furthermore, these results provide more reliable nuclear data for an important diagnostic that is used at the National Ignition Facility to estimate the yield of reaction-in-flight neutrons produced via the inertial-confinement-fusion plasma in deuterium-tritium capsules.

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.

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

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.

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.

Variations in Dream Recall Frequency and Dream Theme Diversity by Age and Sex

Nielsen, Tore

2012-01-01

We assessed dream recall frequency (DRF) and dream theme diversity (DTD) with an internet questionnaire among a cohort of 28,888 male and female participants aged 10–79 years in a cross-sectional design. DRF increased from adolescence (ages 10–19) to early adulthood (20–29) and then decreased again for the next 20 years. The nature of this decrease differed for males and females. For males, it began earlier (30–39), proceeded more gradually, and reached a nadir earlier (40–49) than it did for females. For females, it began later (40–49), dropped more abruptly, and reached nadir later (50–59). Marked sex differences were observed for age strata 10–19 through 40–49 and year-by-year analyses estimated the window for these differences to be more precisely from 14 to 44 years. DTD decreased linearly with age for both sexes up to 50–59 and then dropped even more sharply for 60–79. There was a sex difference favoring males on this measure but only for ages 10–19. Findings replicate, in a single sample, those from several previous studies showing an increase in DRF from adolescence to early adulthood, a subsequent decrease primarily in early and middle adulthood, and different patterns of age-related decrease in the two sexes. Age-related changes in sleep structure, such as decreasing %REM sleep which parallel the observed dream recall changes, might help explain these findings, but these sleep changes are much smaller and more gradual in nature. Changes in the phase and amplitude of circadian rhythms of REM propensity and generational differences in life experiences may also account for some part of the findings. That decreases in DTD parallel known age-related decreases in episodic and autobiographical memory may signify that this new diversity measure indexes an aspect of autobiographical memory that also influences dream recall.

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

PubMed

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.

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.

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.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease of unknown origin and characterized by a relentless loss of motor neurons that causes a progressive muscle weakness until death. Among the several pathogenic mechanisms that have been related to ALS, a dysregulation of calcium-buffering proteins in motor neurons of the brain and spinal cord can make these neurons more vulnerable to disease progression. Downstream regulatory element antagonist modulator (DREAM) is a neuronal calcium-binding protein that plays multiple roles in the nucleus and cytosol. The main aim of this study was focused on the characterization of DREAM and glial fibrillary acid protein (GFAP) in the brain and spinal cord tissues from transgenic SOD1 G93A mice and ALS patients to unravel its potential role under neurodegenerative conditions. The DREAM and GFAP levels in the spinal cord and different brain areas from transgenic SOD1 G93A mice and ALS patients were analyzed by Western blot and immunohistochemistry. Our findings suggest that the calcium-dependent excitotoxicity progressively enhanced in the CNS in ALS could modulate the multifunctional nature of DREAM, strengthening its apoptotic way of action in both motor neurons and astrocytes, which could act as an additional factor to increase neuronal damage. The direct crosstalk between astrocytes and motor neurons can become vulnerable under neurodegenerative conditions, and DREAM could act as an additional switch to enhance motor neuron loss. Together, these findings could pave the way to further study the molecular targets of DREAM to find novel therapeutic strategies to fight ALS.

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.

Absolute calibration accuracy of L4 TM and L5 TM sensor image pairs

The Landsat suite of satellites has collected the longest continuous archive of multispectral data of any land-observing space program. From the Landsat program's inception in 1972 to the present, the Earth science user community has benefited from a historical record of remotely sensed data. However, little attention has been paid to ensuring that the data are calibrated and comparable from mission to mission, Launched in 1982 and 1984 respectively, the Landsat 4 (L4) and Landsat 5 (L5) Thematic Mappers (TM) are the backbone of an extensive archive of moderate resolution Earth imagery. To evaluate the "current" absolute accuracy of these two sensors, image pairs from the L5 TM and L4 TM sensors were compared. The approach involves comparing image statistics derived from large common areas observed eight days apart by the two sensors. The average percent differences in reflectance estimates obtained from the L4 TM agree with those from the L5 TM to within 15 percent. Additional work to characterize the absolute differences between the two sensors over the entire mission is in progress.

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.

Fifteen 1: 250000 and one 1: 1000 000 scale Landsat Thematic Mapper (TM) image mosaic maps are currently being produced of the West Antarctic ice streams on the Shirase and Siple Coasts. Landsat TM images were acquired between 1984 and 1990 in an area bounded approximately by 78°-82.5°S and 120°- 160° W. Landsat TM bands 2, 3 and 4 were combined to produce a single band, thereby maximizing data content and improving the signal-to-noise ratio. The summed single band was processed with a combination of high- and low-pass filters to remove longitudinal striping and normalize solar elevation-angle effects. The images were mosaicked and transformed to a Lambert conformal conic projection using a cubic-convolution algorithm. The projection transformation was controled with ten weighted geodetic ground-control points and internal image-to-image pass points with annotation of major glaciological features. The image maps are being published in two formats: conventional printed map sheets and on a CD-ROM.

This study was undertaken to determine the effect of 24-h transdermal nicotine patches on sleep and dream mentation in 15 smokers aged 20 to 33. Utilising a repeated measures design, it was found that more time awake and more ASDA micro-arousals occurred while wearing the nicotine patch compared to placebo. Also, the percentage of REM sleep decreased, but REM latency and the proportion of time spent in NREM sleep stages did not change significantly. Dream reports containing visual imagery, visual imagery ratings and the number of visualizable nouns were significantly greater from REM compared to Stage 2 awakenings, regardless of patch condition. However, a general interaction effect was observed. Stage 2 dream variables remained equivalent across nicotine and placebo conditions. Within REM sleep, more dream reports containing visual imagery occurred while wearing the nicotine patch, and these were rated as more vivid. The greater frequency of visual imagery reports and higher imagery ratings specifically from REM sleep suggests that previously reported dreaming side effects from 24-h nicotine patches may be specific to REM sleep. Combined with previous animal studies showing that transdermally delivered nicotine blocks PGO activity in REM sleep, the current results do no appear consistent with PGO-based hypotheses of dreaming, such as the Activation-Synthesis (AS) or Activation, Input and Modulation (AIM) models.

The dream of home ownership.

Part of the American Dream involves home ownership and its claim to a stronger investment in one's family, neighborhood, and community. The medical version of that dream is called private practice. Almost overnight, it seems, we have awakened to the reality that most primary care physicians are now employed by large corporations or hospital networks. What does this mean for our patients and the practice of medicine? Did patients lose a sense of ownership when insurance companies began to speak on their behalf? Have boutique practices, Internet sales, and online information banks restored their control? This essay explores the fundamental question, "Does ownership matter?" and suggests what we all can do to retrieve paradise lost.

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

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

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

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
