Dreaming,fenfluramine, and vitamin C.

The effect of increasing doses of fenfluramine on dream patterns was studied in 20 patients receiving a reducing diet with or without a controlled dietary intake of vitamin C daily. 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.     

Usefulness of the analysis of links among dream sources in therapy.

A study of the links among the memory sources of dreams can be carried out by means of an automatic analysis of text files including dream reports and associations. Heuristic criteria can provide plausible explanations for the existence of these links, which generally present a logical and at the same time emotional significance. The aim of this paper is to support the idea that the study of the link patterns among dream sources, in addition to being interesting from the cognitive viewpoint can be also useful for the therapeutic process. An interaction schema is described including four operators: the dreamer (patient), the therapist, the detector of possible links, and the proposer of plausible explanations. Two examples are given of application of this schema. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Dream Intensity Inventory and Chinese people's dream experience frequencies.

The present study aimed to devise a parsimonious instrument for evaluating both the quantitative and qualitative aspects of dream experiences and to quantify Chinese people's dream experiences in ways that facilitated cross-cultural comparisons. The Dream Intensity Inventory was developed and administered to 348 Chinese university students. Individual differences in dream recall frequency were observed, with some participants recalling dreams almost every morning whereas others recalled dreams less than once a month. By contrast, the Chinese participants exhibited less diverse dream awareness frequencies. Multiple dreams in a single night and nightmares were found to be prevalent among the Chinese participants. On the other hand, fewer than half of the participants experienced regularly voluntary control over dream activities and consciousness. The factor analyses of the items in the Dream Intensity Inventory resulted in three readily interpreted factors, which were labeled as the "dream quantity," "altered dream episodes," and "dream vividness" subscales, respectively. When compared with men, women participants had higher frequencies of regular dream experiences including dream awareness, nightmares, and multiple dreams, as measured by the dream quantity subscale.

Sleep and dream patterns of political liberals and conservatives.

In this study the author examined the dreams of American liberals and conservatives to highlight patterns that might correlate with their opposing political views. A total of 234 participants (134 self-described liberals and 100 self-described conservatives) completed a lengthy sleep and dream survey, and their answers revealed several notable patterns. People of both political persuasions shared a common substrate of basic human sleep and dream experience. Conservatives slept somewhat more soundly, with fewer remembered dreams. Liberals were more restless in their sleep and had a more active and varied dream life. In contrast to a previous study, liberals reported a somewhat greater proportion of bad dreams and nightmares. Consistent with earlier research, the dreams of conservatives were more mundane, whereas the dreams of liberals were more bizarre. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Dream Recall Frequency and Dream Detail as Mediated by Personality, Behavior, and Attitude

Many studies investigated how personality, behavior, and attitude mediate dream recall, but few distinguish between measures of dream recall frequency: the number of dreams experienced in a specified time frame and dream detail: individual ratings of vividness or detailed content of dreams. This study compared undergraduates' (n = 173) self-reported dream recall frequency, and dream detail, with behaviors, attitude toward dreaming, and scores on scales of Extraversion/Introversion and Type A/B. Dream recall frequency and dream detail manifested different patterns of association in relation to behaviors, attitude and personality. Dream recall frequency was associated with the frequency of experiencing emotionally disturbing dreams and trying to interpret dreams, while detail of dreams was associated with positive attitude toward dreaming and Type B personality. Although males and females both held positive attitudes toward dreaming, females experienced more emotionally disturbing dreams and felt unable to control their dreams. Interactions between personality and gender emerged for behaviors associated with dreaming. Researchers are encouraged to differentiate between dream recall frequency and dream detail.     

Perceived change in the affect associated with dreams: The fading affect bias and its moderators.

Eighty-two undergraduate participants kept dream diaries for a month. Five dreams were randomly selected from each diary and were returned to participants. They rated the affect produced by the dream at its occurrence and at its recall, as well as a number of other characteristics of the dream and characteristics of the context in which the dream occurred. Results revealed that, like memories for real autobiographical events, the negative affect associated with dreams generally faded faster than the positive affect associated with dreams (a Fading Affect Bias, or FAB). The data also showed that the FAB did not occur for: (a) dreams that were remembered to contain information that dreamers believed came true at a later date, (b) dreamers who had reportedly taken recreational drugs prior to their dream, (c) dreams remembered as lacking sound, and (d) dreams remembered as very quiet.

The influence of impactful dreams on self-perceptual depth and spiritual transformation.

Two studies contrasted the short-term effects of nightmares, existential dreams, and transcendent dreams (Busink & Kuiken, 1996; Kuiken & Sikora, 1993). Results from Study 1 indicated that existential dreams were more likely than mundane dreams, transcendent dreams, or nightmares to be followed by reported self-perceptual depth; also, transcendent dreams were more likely than mundane dreams, existential dreams, or nightmares to be followed by reported spiritual transformation. Results from Study 2 replicated these findings for existential dreams, indicating also that the type of spiritual transformation associated with transcendent dreams involved an ecstatic sense of release from everyday entanglements. Both existential dreams and transcendent dreams moved the dreamer toward an unbounded sense of life in all things, as did lucid forms of all three dream types. Such unbounded enlivenment suggests an aesthetic substrate to the changes induced by each of these dream types. The contrasting short-term effects of impactful dream types may require integration into a comprehensive model of long-term dream function.

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.

Children's Dreams and Nightmares: Emerging Trends in Research.

New manifest content analysis research on children's dreams and nightmares provides insights into how dreaming reveals developmental changes over time. Five culturally diverse research studies were conducted with varied methods for dream collection that included laboratory-collected dreams, as well as written journals, audiotaped dreams, and retrospectively recalled dreams. As children grow older, they are more able to recall dreams, dream narratives increase in length, and dreams are characterized by decreasing levels of passive victimization and have more elaborate character interactions. Age and gender differences in recall, interactions, and gender of dream characters indicate that dream research is a fertile area for studying child development and the changing function of dreams over time.

Big dreams: An analysis using central image intensity, content analysis, and word searches.

The authors provide empirical data to help answer the question of what distinguishes “big dreams” (Jung, 1974) from ordinary dreams. Reported here are the results of a multifaceted quantitative analysis of 162 most recent dreams and 162 most memorable dreams gathered from the same group of individuals. This matched collection of recent and memorable dream reports was analyzed by a novel combination of three quantitative methods: Hartmann's (1998, 2008) research on central images, Hall and Van de Castle's (1966) content analysis, and Bulkeley's (2009b) word search approach. Using these different methods of analysis on the same two sets of dreams provided an unusually detailed portrait of the basic patterns of big dreams. The results suggest that big dreams are distinguished by a tendency toward “primal” qualities of form and content: more intense imagery, more nature references, more physical aggression, more family characters, more fantastic/imaginary beings, and more magical happenings, along with less high-order cognition and less connection to ordinary daily surroundings.

A relationship between nightmare content and somatic stimuli in a sleep-disordered population: A preliminary study.

This study aimed to examine the influence of specific sleep disorders on dream content. The authors hypothesized that: (a) waking somatic concerns influence dream content and (b) somatic stimulation associated with specific sleep disorders influence dream content items. The subjects (N = 124) were included if they demonstrated obstructive sleep apnea, narcolepsy, an EEG arousal disorder during sleep, or periodic leg movements during sleep (PLMS), based on standard polysomnography. The 42-item Wahler Physical Symptom Inventory was used to quantify somatic concerns. Dream content and frequency was assessed with a 37-item Dream Questionnaire. Ten symptom-dream pairs were selected as mutually relevant and subjected to chi-square analysis. 84.6% of all subjects reported having bad dreams (N = 105). A significant proportion of patients who complain of excessive perspiration dream about perspiring, and significant proportions of those who report difficulty breathing while awake dream about feelings of choking and suffocation. Recurring dreams and dreams of paralysis are significantly more prominent in patients with narcolepsy. Patients with sleep apnea do not dream of choking/feelings of suffocation with greater frequency than nonapneics. These findings suggest that somatic stimulation associated with specific sleep disorders appears to have an inconsistent influence on certain dream content items. Furthermore, dream mentation appears to feature waking concerns, rather that being related to events associated with during sleep disorders.

A Laboratory Study of Sleep and Dreaming in a Case of Asperger's Syndrome

Asperger's Syndrome (AS) is a pervasive developmental disorder whose continuity with High-Functioning Autism is still a matter of debate. Clinical observations suggest that patients with AS may present the same sleep disorders as autistic patients, including difficulties in initiating and maintaining sleep as well as poor dream recall. We recorded the sleep of a 25-year-old male patient with AS for two nights using a full EEG montage and compared the second night to that of a group of normal participants. We found low levels of slow wave sleep (SWS: stages 3 + 4), high levels of stage 1, and a large number of awakenings. The organization of REM sleep was unremarkable, including normal REM density. Analyses of phasic EEG events revealed a very low incidence of sleep spindles and a normal number of K-complexes over bilateral frontal and central EEG leads. In order to collect dream reports, the patient was awakened three times over two nights following at least 15 minutes of REM sleep in each case. On each occasion the patient was not aware of any mental activity happening just prior to awakening. These observations are discussed with regards to the connections that may exist between EEG sleep spindle activity, selective attention, and the capacity to generate a dream report.     

The Relationship of Dream Content and Changes in Daytime Mood in Traumatized vs. Non-Traumatized Children

The study examined how the mood changes from night to morning, and how dysphoric dream contents associate with this change among children who live in traumatic environment and their controls from peaceful area. The sample consisted of 413 Palestinian boys and girls of 6–15 years of age, the mean age being 11.22 ± 2.64. The participants filled in a seven-day dream diary in which they recorded their recalled dreams every morning. First, the results, confirmed that mood change from evening to morning is a general dream function: age and gender are not related to the change. The mood chance was rather associated with what and whom the children dreamt about. Second, the hypothesis of the trauma group showing less change in dysphoric dream content and in the intensity of negative morning mood across a period of time of seven days was not confirmed. On the contrary, the results showed that both dreams incorporating dysphoric themes and negative morning mood decreased only among children living in traumatic conditions. Third, it was hypothesized that there is a stronger association between presleep negative mood and dysphoric dreams, as well as between the dysphoric dreams and negative morning mood among children living in traumatic environment than among children from peaceful area. Contrary to the hypothesis, results for the trauma group revealed a reverse association between evening mood and dream contents: the more afraid, angry and worried children felt in the evening, the more Happy recreation dreams they reported, and the happier evening mood they reported, the more Threatening stranger dreams they had. However, concurring with the hypothesis, a direct association was found between dysphoric dreams and negative morning mood in the trauma group. The more children dreamt about Threatening strangers, the more afraid, angry and worried they felt in the morning. The discussion proposes a model of the correcting or balancing dream function that is characterized by an reverse assimilation of incorporating evening mood into dreams, and by a direct accommodation of dream content into morning mood.     

The central image makes "big" dreams big: The central image as the emotional heart of the dream.

"Big dreams" are hard to define. This paper considers "big" dreams under several more easily definable subcategories: memorable dreams; important dreams (labeled by dreamer); significant dreams; and impactful dreams. Past studies are reviewed, and five new preliminary studies are presented showing that a powerful Central Image (CI) distinguishes "big" dreams in all subcategories. 1) Dreams labeled "important" by the dreamer have higher CI intensity than dreams labeled "unimportant." 2) Dreams labeled "especially significant" have especially high CI intensity. 3) Impactful dreams (leading to a new discovery) have a very high CI intensity. 4) The dreams of people who score very "thin" on the Boundary Questionnaire (BQ)--sometimes called "dream-people"--have higher CI intensity than the dreams of people who score "thick." 5) In a separate, larger group, there is a significant positive correlation between CI intensity and "thinness." It appears that CI intensity is an important measure of the "bigness" of dreams. The present results are consistent with the Contemporary Theory of Dreaming which states that dreams involve making connections guided by emotion, that the Ci of the dream pictures the emotion, and that CI intensity measures the power of the underlying emotion. "Big" dreams are dreams with great emotional power and have powerful Central Images. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Anorexia dreaming: A case study.

A case study is presented focusing on a dream of a severely anorectic woman. The dream occurred at a point when the disorder had become life threatening. The dream is discussed in terms of its significance in the dreamer's experience, its implications for the use of dreams in psychotherapy, and its relevance for the broader literature on psychopathology and dreams. Archetypal psychology's aesthetic, and phenomenological approach to dreams is presented as a framework for understanding the ongoing significance of significant dreams such as the one presented here.

Representation of the self in REM and NREM dreams.

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.

Dreams of female university students: Content analysis and the relationship to discovery via the Ullman method.

This study extended the research on the dreams of students by examining the actual content of female students' dreams and to what extent the content related to discovery via the Ullman method. Further analyses were conducted to examine what content categories significantly predicted discovery. Participants were 56 female undergraduate students who provided a dream and participated in the Ullman method of group interpretation. Dream content was analyzed via the Hall and Van de Castle method of content analysis. Many significant correlations were observed among dream content categories, discovery categories, and dream content and discovery categories together. Findings were representative of the sample being examined and provided evidence of the continuity hypothesis. Results both support and extend previous research on the dreams of students. Furthermore, specific categories of dream content were found to significantly predict discovery categories. Limitations and future directions are discussed.

REM dreaming in the transition from late childhood to adolescence: A longitudinal study.

In this longitudinal developmental study, 12 boys and 12 girls provided REM dreams at 3 age levels: 9-11, 11-13, and 13-15 years. A total of 551 dreams were coded by 2 independent raters using C. Hall and R. Van de Castle's (1966) content categories. In addition, ratings of dream realism, the dreamer's self-involvement, and the frequency of speech acts were carried out. There was little change in the basic content categories of REM dreams. However, the frequency of unrealistic dream elements declined, whereas the ability to inventively put together separate contents of the memory system to produce meaningful scenes increased. Self-representation changed from passive experience to interactive involvement, along with an increasing number of speech acts by the dreamer. The similarity of the findings with Hall and Van de Castle categories to findings with home dreams from the same 24 participants is discussed.

Do we think dreams are in black and white due to memory problems?

The present study was designed to investigate whether memory processes play a role in why some persons say their dreams are black and white. The findings indicate that the percentages of black and white dreams are related negatively to color memory and dream recall frequency. When colors were recorded immediately after the dream was recorded, the percentage of black and white dream elements dropped to 2.7%. When participants were presented the option that dream colors might not be remembered, the percentage of explicit black and white dreams became very small, and the findings are thus in line with the continuity hypothesis of dreaming. Future studies might use extensive training of color memory and dream recall in order to investigate whether highly trained persons still have some dreams or dream elements that are in black and white.
