The relationship between video game play and threat simulation dreams.

Revonsuo proposes an evolutionary theory of dreaming in which dreams allow an individual to prepare for real world threats in the safety of the virtual setting of the dream world. Based upon previous work examining the dreams of video game players, it was hypothesized that high-end gamers would experience fewer threat simulation dreams because of frequent threat resolution rehearsal during game play. Subjects were asked to report a night before dream and fill out surveys regarding their gaming history, media use, and dream experiences. Using a factor analysis, support for the main hypothesis was found. Individuals with a history of game play experienced fewer threat severity variables in their dreams.

Paranoia in dreams and the classification of typical dreams.

The present study was geared toward expanding the previous evidence for the thematic similarities between dreaming and psychosis. Themes derived from delusions that characterize psychotic and schizophrenia-spectrum disorders, together with the modified Typical Dream Questionnaire, were administered to 280 Chinese participants from Hong Kong. These delusional themes served as some continuous variables for evaluating the degree to which the narrative contents of dreaming can be compared with those of psychotic and schizophrenia-spectrum disorders. It was found that delusions of various types, with various levels of bizarreness, could be observed in dreams. This was particularly true for themes involving paranoid suspiciousness, such as blaming others for making troubles and feeling that others are not giving proper credit for one’s achievements, which were dreamed by a majority of the participants. The current findings generated by the exploratory factor analyses precisely replicated Yu’s (2009) previous delusional model that classified dream themes into the Ego Ideal, Grandiosity, and Persecution categories. Moreover, the present study expanded the Ego Ideal category, developed measures for assessing the delusional inclination during dreaming, and discussed the reciprocal, triadic dynamics between the three major categories of dream themes.

Video game play and lucid dreams: Implications for the development of consciousness.

The improvement of various cognitive skills associated with video game play has been well documented; however, the development of consciousness implications have not been considered. In the present study several potential indicators of consciousness development, including and especially lucid dreaming frequency, were examined as a function of video game play. In the first study, high video game players were more likely to report lucid dreams, observer dreams, and dream control when dream recall frequency and motion disorientation during play were controlled. There were no similar differences in other consciousness development indices. In the second study, a slightly different pattern of results occurred because of respondents all being frequent players.

A Historical Loop of One Hundred Years: Similarities Between 19th Century and Contemporary Dream Research

Contemporary cognitive and neuropsychological approaches to dreaming show striking methodological and conceptual similarities with the scientific dream literature of the last century. The use of introspective dream reports and the emphasis on dream phenomenology are characteristic of both periods but were bannished during the first half of this century, the former by behaviorism, the latter by psychoanalysis. Three main common axioms of 19th century and contemporary dream research are described: (a) dream experience results from cognitive syntheses realized in the absence of external constraints; (b) dream narrative or dream coherency involves mental associative mechanisms; (c) dream bizarreness emerges from a cerebral state characterized by functional dissociation. According to these three axioms, the observation of dream phenomena reveals that distinct cognitive processes might function in a partly autonomous, automatic, and dissociated way, making dreaming a unique model of these cognitive processes.     

Definitions of Dream: A Paradigm for Comparing Field Descriptive Specific Studies of Dream

A single definition for dreaming is most likely impossible given the wide spectrum of fields engaged in the study of dreaming, and the diversity in currently applied definitions. Many studies do not specify a definition, yet results are likely to be comparable only when comparable definitions of the topic are used. The alternative is to develop a classification system organizing the multiplicity of definitions for dream. A dream should not be exclusively defined as a non-conscious electrophysiologic state. Dreaming is, at least in part, a mental experience that can be described during waking consciousness. Definitions for dreaming should be utilized in research and discussion which address the various axes which define dreaming: Wake/sleep, Recall, and Content.     

Theory of Mind in Dreaming: Awareness of Feelings and Thoughts of Others in Dreams.

If the awareness of what others are thinking and the ability to attribute feelings to others characterizes both waking and dreaming consciousness, it suggests that a social species like man has a state-independent need for a theory of mind; that is, an ability to know that others have feelings. The authors performed 2 studies, the first of which consisted of 35 participants who submitted 320 dream reports containing more than 1,200 dream characters and the second consisted of 24 participants who submitted 151 dream reports with 543 dream events. Participants reported that as subjects in their own dreams they were aware that their dream characters had feelings and thoughts about them. This finding shows that awareness of what others are feeling is a robust aspect of consciousness that is maintained despite the changed chemistry and changed activation patterns of the brain's neuronal connections during dreaming.

Significant Dreams: Bizarre or Beautiful?

The literature on highly significant dreams is filled with references to the bizarreness of their content. On the other hand, the concept of beauty is rarely if ever mentioned in relation to these dreams. Grounded in archetypal psychology's tenet that psychological life is aesthetic life, this article argues that the enduring, even life-long, influence some dreams have on the dreamer's life may be better approached through the idea of beauty than through the idea of bizarreness. The argument builds on Hunt's (1989, 1995) theoretical model of the nature of consciousness and dream multiplicity with its emphasis on cross-modal synesthesia as well as on insights provided by Scarry's (1999) recent essay on beauty. A detailed account of how one composer's work was profoundly influenced by his most significant dream is presented to illustrate this aesthetic approach to understanding the on-going significance of significant dreams.     

Review of The Mind at Night: The New Science of How and Why We Dream.

In this article I review "The Mind at Night: The New Science of How and Why We Dream," written by Andrea Rock. To begin with this book is an exciting journey through modern dream research. Scientific facts, which are skillfully explained, are complemented by personal accounts of well-known researchers in the field obtained through interviews. The diversity of the themes addressed in the book (e.g., sleep and memory, animal research, imaging studies, dream content analysis, consciousness research, creativity, and lucid dreaming) clearly shows the extensive "detective work" the author has accomplished. The major problem I had--as a researcher in this field--was the structure, or the lack of structure, within the book. Because of the way the book is organized, I decided to structure this review along the following themes: REM sleep, REM sleep and dreaming, biology of dreaming, dream content findings, and the integration of dream research into cognitive neuroscience in general. Despite the lack of structure of the book, Andrea Rock has written a wonderful book about modern dream research that is stimulating for researchers as well as for interested lay persons. I recommend it to everyone who is interested in dream research, the old question of the mind-body relationship, or understanding consciousness in general.

Trauma, dreaming, and psychological distress among Kurdish children.

The authors examined (a) how traumatic events are associated with children's dream structure and content and (b) which dream characteristics might moderate the negative impact of traumatic events on mental health. Participants were 122 Kurdish children (9-17 years old, M = 13.02, SD = 1.66). Their dreams were collected during 1 week using a semistructured dream diary and scored according to the dream atmosphere, the role of the dreamer, bizarreness, narrative quality, fragmentation and resolution, and content such as themes of death, persecution and rejection, hostility, and anxiety. The results substantiated the hypothesis that children exposed to a high level of traumatic events would report dreams characterized by unpleasant atmosphere, fragmented flow, and low levels of bizarre narrative quality. Pleasant dreams containing complete narratives and happy endings moderated the negative impact of traumatic events on children's mental health. The authors argue that dreaming allows cognitive-emotional processing of traumatic events and may thus enhance child well-being in war conditions.

The role of mood congruency memory effects in dream recall: A pilot study.

A methodological issue in research relating daytime mood to dream content is the question of whether mood congruency effects—that is, recalling more negative events if the current mood is more negative—also play a role in the dream recall process. This study adopted an indirect approach by testing the hypothesis that interindividual differences in mood congruency effects in a memory task carried out in the daytime correlate with mood congruency effects in dream recall (recalling more negative dream emotions, as one would predict on the basis of the current stress level or overall mood state). The findings, however, did not support the hypothesis of mood congruency effects and, thus, rule out that the findings regarding the continuity hypothesis of dreaming are biased by selective recall. Studies with different methodological approaches are necessary to validate this study’s findings. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Forgotten fantasies? Modernity, reenchantment, and dream consciousness.

Why are dreams easily forgotten or difficult to remember? Dream memory is usually attributed to stored fantasies and imaginations in sleep that have distant or no relevance to waking consciousness. Lack of dream recall suggests the modern emphasis on the significance of waking realities at the expense of oneiric experiences. Yet, in the ancient West and many contemporary non-Western societies, dreaming constitutes an unbroken chain of memory to the organization of everyday life. However, reenchantment in the modern context has given new importance to dream consciousness as vital to the development of the creative self. Emphasis on dream practices or dreamwork as leading to various forms of dream control suggests a quest for mastery of inner space. In this regard, training and motivation in dream recall provide an essential tool for advancing the self's well-being. Dreams are not treated as forgotten fantasies but dynamic pathways to new meanings of the self. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Content analysis does not belong in any theoretical category: A comment on Hartmann's "meteorite–gemstone" continuum.

This brief comment provides a detailed critique of the inclusion of the widely used Hall and Van de Castle (1966) coding system for the study of dream content in the “meteorite” category in a recent article by Ernest Hartmann (2010), a category for theorists who presumably believe that dreams come from “somewhere else.” The critique notes that content analysis is a methodology, not a theory, and that it has been used to study newspaper articles, speeches, and many other mundane texts. In the case of dream studies, it has produced results that have led many dream researchers to conclude that dreams belonged in Hartmann's “gemstone” category, a category for cognitively oriented theorists who see dreaming as 1 point on a continuum that includes daydreaming, reveries, and more rigorous focused thought. Several other problems with Hartmann's discussion of content analysis are also discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Meteorite or gemstone? Dreaming as one end of a continuum of functioning: Implications for research and for the use of dreams in therapy and self-knowledge.

Is a dream a meteorite—a bit of material arriving from a distant place that needs to be carefully analyzed to give us knowledge about that place (outside or inside us)? Is it a strange text which has come to us in a foreign language, that needs to be translated into our own? This “meteorite view” is held by some religious and spiritual persons, by many orthodox psychoanalysts and other therapists, and implicitly by many researchers. They all see the dream as something alien, something totally different from our ordinary mental functioning. This paper presents a great deal of research favoring an alternate view—that the dream is an earth-stone, not an alien stone. It may be impressive and beautiful (gemstone), but it's still an earth-stone. The dream is part of our mental functioning. It is one end of a continuum, running from focused waking thought, through looser thought, fantasy, daydreaming, reverie and dreaming. We review reasons why dreams are often considered “totally different”: they're perceptual, not conceptual; they're bizarre; they are “so real”; they're so easily forgotten; they're involuntary; they occur in REM sleep—a totally different state. We demonstrate that none of these reasons are persuasive. In each sense, there is overlap between dreams and other forms of functioning. The continuum view leads to different kinds of research and a different style of dreamwork. It also helps answer questions the field has long struggled with including: Should we study “a dream” or “dreaming”? Are dreams meaningful or meaningless?

Investigation of dream reports after transcranial direct current stimulation (tDCs) during slow wave sleep (SWS)

Despite being a prominent feature of REM sleep, dreams have also been reported from NREM sleep. Neuroimaging studies have revealed regional patterns of brain activation and deactivation during REM and NREM sleep, with frontal and posterior parietal cortices implicated as brain regions involved in dreaming. From our recent stage 2 study it was revealed that tDCs of these brain regions during this stage of sleep resulted in an increase in reported dream imagery. Thus, the aim of this study was to investigate the effect of simultaneous anodal and cathodal tDCs applied to the right posterior parietal and frontal cortex (respectively) during SWS on dream recall. After 60 s of continuous SWS, participants were administered either tDCs, low tDCs, or blank control, followed by a 60 s delay period to confirm SWS before waking the participant for dream report collection. These conditions were administered in a counterbalanced order across the night. Analyses revealed no significant difference between conditions in the three dream measures. However, an analysis of visualizable nouns to total words revealed a significantly higher ratio in the low tDCs condition compared to the tDCs condition. It was concluded that tDCs had no appreciable effect on reported dream imagery. However, such findings are preliminary as they are from a research protocol which is in the process of refinement with more definitive results expected in future. Thus, further studies should now investigate the application of tDCs using improved methodologies and to other cortical regions implicated in the process of dreaming.

     

Virtual reality training of lucid dreaming

Metacognitive reflections on one''s current state of mind are largely absent during dreaming. Lucid dreaming as the exception to this rule is a rare phenomenon; however, its occurrence can be facilitated through cognitive training. A central idea of respective training strategies is to regularly question one''s phenomenal experience: is the currently experienced world real, or just a dream? Here, we tested if such lucid dreaming training can be enhanced with dream-like virtual reality (VR): over the course of four weeks, volunteers underwent lucid dreaming training in VR scenarios comprising dream-like elements, classical lucid dreaming training or no training. We found that VR-assisted training led to significantly stronger increases in lucid dreaming compared to the no-training condition. Eye signal-verified lucid dreams during polysomnography supported behavioural results. We discuss the potential mechanisms underlying these findings, in particular the role of synthetic dream-like experiences, incorporation of VR content in dream imagery serving as memory cues, and extended dissociative effects of VR session on subsequent experiences that might amplify lucid dreaming training during wakefulness.This article is part of the theme issue ‘Offline perception: voluntary and spontaneous perceptual experiences without matching external stimulation''.     

Electronic media and lucid-control dreams: Morning after reports.

Lucid dreams, as well as control dreams, have recently been reported as associated with video game play (Gackenbach, 2006). In this study, dreams were collected from the morning after a night of rested sleep as well as electronic media use from the day before the dream. In a factor analysis, lucid and control dreams were associated with all electronic media use but most strongly with video game play. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Questionnaires and Diaries as Research Instruments in Dream Research: Methodological Issues

Dream questionnaires are widely used in dream research to measure dream recall frequency and various aspects of dream life. The present study has investigated the intercorrelation between questionnaire and diary measures. 285 participants completed a dream questionnaire and kept a dream diary over a two-week period. Results indicate that keeping a dream diary increased dream recall in low and medium dream recallers but decreased dream recall in high dream recallers. The correlation coefficients between questionnaire items measuring aspects of dream content and diary data were large, except for a more complex scale (realism/bizarreness). In the low recall group, however, considerably lower coefficients were found indicating that recall and sampling processes affect the response to global items measuring dream content. Using the example of testing gender differences, the findings of the present study clearly indicate that the measurement technique affects the results. Whereas sufficient internal consistency and retest reliability have been demonstrated for various dream questionnaires, future research should focus on the aspects of validity by comparing questionnaire data to dream content analysis of at least 20 dreams per person.     

Austrian Dream Behavior: Results of a Representative Population Survey

This study was based on a survey of a representative sample of 1000 Austrians who were questioned about their sleep and dream behavior. About two-thirds of the respondents reported that they generally recalled at least one dream per month. Dream recall frequency decreased with advancing age, but did not differ between men and women. Fifty-five percent of the respondents characterized the affective content of their dreams: 29% reported neutral, 20% positive, and 6% negative dreams. Four percent of the sample reported suffering from nightmares. These respondents more frequently reported snoring, interrupted sleep, daytime somnolence, anxiety and nervousness, depression, high dream recall, recurrent dreams, and dreaming in color. Twenty-six percent of the total sample reported that sometimes they realized during their dreams that they were dreaming. These respondents more frequently reported family problems, high dream recall, positive dream content, recurrent dreams, dreaming in color, and nightmares.     

Vatted dreams: neurophilosophy and the politics of phenomenal internalism

Despite much social‐scientific work on the neurosciences, little ethnographic and historical attention has been paid to the field of neurophilosophy. Yet anthropologists studying brain research occasionally critique neurophilosophers for reducing the mind to the brain while affirmatively citing philosophers of mind who present the mind as emerging from interactions between brain, body, and environment. This article examines the ostracized camp of so‐called ‘phenomenal internalists’ – neurophilosophers who believe that consciousness can supervene on the brain alone. This ontological commitment is driven by certain existential and political experiences from false awakenings to disenchantment with the counterculture of the 1970s. But it also draws from neuroscientific research on the dreaming brain. The inquiry concludes with a plea to anthropologists to attend to relations of detachment, both social and neural, and to reconsider their own ontological commitment to externalism in the light of dream research.     

Invisible Elites? Authority and the Dream

This paper seeks to develop a perspective on the dynamic interplay between dreaming, culture and identity. A spectrum of examples show that dream imagery has had and still has today tremendous cultural significance across a whole array of historical, religious and contemporary political and personal contexts. The visionary dream is shown to have underpinned the charter myths of both Israel and Serbia/Kosovo as well as having been the generative source of a core body of hierarchically organised spiritual knowledge in Islamic societies, possibly including the Taliban. Annunciation and calling dreams are commonplace in shamanic and some other societies and individuals can have dreams that prefigure aspects of their developing personal myths. The power and politics of dreaming is further exemplified in the author's example from his dreamwork group that suggest we can dream within the cultural and oppressive stereotypes of our gendered and racist time. Our experience of reality is presented as being dynamically co-created out of both the normative events of everyday life as well as from the human experience of the dream in its powerful and politically evocative forms.
