Reading dream literature: frequency, influencing factors, and self-rated benefit

Dream books have a very long history, but systematic research on how many people have read magazine articles or books on dreams and whether reading such literature is beneficial to the dreamer is scarce. In the present sample of 444 people (mostly psychology students), about 75% of the participants stated that they had read at least one magazine article on dreams, and more than 40% had read at least one book about dreams. The main factor associated with the frequency of reading dream literature was a positive attitude toward dreaming, whereas personality factors play a minor role in explaining interindividual differences in this variable. The self-rated benefit of reading dream literature varied greatly, from not helpful at all to very helpful, and was associated with dream recall frequency and positive attitude toward dreaming. Using this approach in a more sophisticated way, eliciting details about the kinds of information participants have read would help researchers learn more about what techniques of dream work are effective and thus complement the research carried out in therapist-guided sessions.     

Alexithymia and aspects of dreaming: Differential associations of alexithymia facets with dream variables

Research on aspects of dreaming associated with alexithymia has yielded mixed results. The present study recruited a young adult online sample of 577 participants who completed validated indices of alexithymia, emotion suppression, negative moods, and eight aspects of dreaming, with a focus on evaluating a counterintuitive previous finding that alexithymia and two of its core facets were associated with greater self-reported typical emotional intensity of dreams. Total alexithymia and facet scores showed differential relationships to aspects of dreaming including dream recall frequency, emotionality, meaningfulness, nightmare frequency, nightmare distress, usefulness of dreams in problem-solving and creativity, and learning about oneself through dreams. Planned hierarchical regression controlling for demographics, alcohol use, and dream recall frequency indicated that the difficulties identifying feelings (DIF) facet of alexithymia was a significant positive predictor of dream emotionality, whereas the externally oriented thinking (EOT) facet was a significant negative predictor. Stress, but not emotion suppression, mediated the positive relationship between DIF and dream emotionality. The likely role of dream emotionality in higher ratings of nightmare distress, dream meaningfulness, and learning about oneself through dreams among those with higher DIF scores is noted, along with other findings and the strengths and limitations of the study.     

Threat in dreams: an adaptation?

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

Minding the Dreamer Within: An Experimental Study on the Effects of Enhanced Dream Recall on Creative Thinking

Several studies have found an association between frequency of dream recall and creativity. We tested the hypothesis that training individuals to increase dream recall by means of a daily dream log would increase scores on the Torrance Test of Creative Thinking (TTCT). One hundred twenty‐five participants completed a baseline measure of creativity (TTCT, figural version) as well as of dream recall, dissociation, thinness of psychological boundaries, mindful‐attention awareness, and well‐being. Participants were randomly allocated to two groups: the experimental group (n = 55) received a daily dream log; while the control group (n = 32) received a similarly phrased log registering memories of a vivid episode from the previous day. After 27 days, all participants completed follow‐up measurements identical to those at baseline. A non‐randomized non‐intervention group (n = 35) was used to test for practice effects on the TTCT. There was significant selective increase for the “creative strengths” component, which was only observed in the experimental group. There were significant correlations between creativity and dissociation as well as between creativity and thinness of psychological boundaries. Enhanced dream recall through daily dream logging fosters aspects of creativity. Associations between creativity, dissociation, and thinness of boundaries, suggest that increased awareness to dreams increases creativity through a “loosening” of stereotyped thinking pattern.     

Creativity and Dream Recall

The literature on creativity and dream recall often found significant positive correlations between measures of creativity and dream recall frequency (DRF). The present study investigated the relation between creative interests and DRF in detail. The findings confirmed the results reported in the literature, according to which persons with visual and verbal creative skills recalled more dreams. It is suggested that the visual memory may serve as a mediator variable in the relation between creativity and DRF.     

Frequency of lucid dreaming in a representative German sample

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.     

Jungian personality typology and the recall of everyday and archetypal dreams

Hypotheses concerning the relations among personality types, neuroticism, and the recall of archetypal dreams were derived from Jungian theory. Dream records were obtained from a nonclinical population in two stages: first, recall of the most recent, most vivid, and earliest remembered dreams (N = 146), and then dream recall on awakening, over an average of 23 nights, from 30 of the first-sample subjects. A total of 697 dreams was recorded. Subjects also completed the Eysenck Personality Inventory (EPI) the Myers-Briggs Personality Inventory, and a Dreaming Questionnaire. Dream archetypality was rated in accordance with procedures of H. Y. Kluger. The distribution of archetypal dreams across earliest (n = 106), most vivid (n = 105), and most recent (n = 102) dream types matched Kluger's earlier results. The dream diary recall data showed that Jungian intuitives, as measured via Myers-Briggs continuous scores, recalled more archetypal dreams; introverts, as measured via Myers-Briggs continuous scores, recalled more everyday dreams; high EPI neuroticism scorers recalled fewer archetypal dreams. The results support several propositions of Jungian personality theory.     

Artistic and Scientific Creative Behavior: Openness and the Mediating Role of Interests

The arts and sciences have been identified as two specific domains that are dependent upon the creative process. A total of 369 undergraduate students served as research participants in two separate studies. In the first study, participants (N = 238) completed a measure of Openness to Experience (NEO‐PI; McCrae & Costa, 1999) and a questionnaire assessing artistic and scientific creativity (ASAS; Guastello & Shissler, 1994). Results from study 1 indicated that the Aesthetics and Actions personality traits were significantly related to artistic creativity, while the Ideas trait was the only lower level personality trait to significantly correlate with scientific creativity. In the second study, participants (N = 131) completed a measure of Openness to Experience (NEO‐PI), Vocational Interests (Holland, 1985), and an artistic and scientific creativity questionnaire (Guastello & Shissler, 1994). Findings from study 1 were largely replicated in study 2. Namely, Aesthetics and Ideas were significantly related with artistic and scientific creativity, respectively. Results from partial correlation computations were used to identify specific personality traits that were used in a series of regression models testing the second goal of the second study. Specifically, vocational interests were observed to mediate the relationship between personality dispositions and creativity. Results suggest the ability of lower level personality traits of Openness to differentiate between artistic and scientific creativity. In addition, results lend support for the motivational aspect of vocational interests.     

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

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.

Inducing lucid dreams by olfactory-cued reactivation of reality testing during early-morning sleep: A proof of concept

The reliable induction of lucid dreams is a challenge in lucid dream research. In a previous study by our research group we were able to induce in about 50% of the participants a lucid dream in a single sleep laboratory night by combining a wake-up-back-to-bed sleep protocol and a mnemonic technique. In the present study, we extended our previous procedure by additional presentation of an odor during sleep to reactivate memory traces about reality testing. In total 16 male participants spent a single night in the sleep lab whereas the procedure induced in two participants a lucid dream (12.5%). The induction rate stays below the success rate of our previous study and therefore odor-cueing seems not a promising technique for inducing lucid dreams. Beside the odor presentation, several other methodological changes have been made, which will be discussed and hopefully help further dream engineering to improve induction techniques.     

Frequency of Nightmares and Gender Significantly Predict Distressing Dreams of German Athletes Before Competitions or Games

Important sports events are highlights and stressful situations in every athlete's career. This stress might alter the dream content of athletes and consequently evoke disturbed dreaming. In this study, the authors asked 840 German athletes from various sports about distressing dreams on the nights before an important competition or game. About 15% of the athletes stated that they experienced at least 1 distressing dream before an important competition or game during the preceding 12 months. An almost equal number of athletes reported at least 1 distressing dream in their sports career. With respect to the base rate, in about 3% of the events a distressing dream occurred. Reported dream content referred mainly to athletic failure. The main risk factor for an athlete experiencing a distressing dream before a competition appears to be the frequency of experienced nightmares in general. Future research should use diary techniques to study the impact of distressing dreams on the next-day athletic performance in a competition or game.     

Absorption in imaginings, sex-role orientation, and the recall of dreams by males and females

Questionnaire measures of dream recall frequency, number of sensory qualities in dreams and emotion in dreams were correlated with several imaginal ability and personality variables in male and female college students. Absorption (i.e., subjects' degree of involvement in such activities as daydreaming, watching a movie, etc.) was the most important predictor of dream variables in females. In males sex-role orientation contrary to stereotype (i.e., femininity) was the only variable significantly related to a dream variable (i.e., frequency of dream recall). The implications of these sex differences for research on dream recall are discussed.     

The Anomalous Foundations of Dream Telling: Objective Solipsism and the Problem of Meaning

Little sociological attention is directed to dreams and dreaming, and none at all is directed to how people tell one another about dreams. Ordinary settings in which dreams are told mimic the conditions of “breaching” experiments and should produce anomie, but dream telling proceeds without trouble. Foundational orientations of ordinary dream talk assimilate into professional dream studies, where dream narratives are “data” and the analysis of narratives is “dream analysis.” That such practices proceed without trouble poses some interesting problems for sociology in terms of how anyone experiences “constraint” in the telling and hearing of dreams.     

Creativity and Dreaming: Correlation of Reported Dream Incorporation Into Waking Behavior With Level and Type of Creative Interest

Dreaming has been postulated to be a functional intrapersonal component of the creative experience. In this study, a previously validated questionnaire is used in a sleep laboratory population (N = 517) to assess levels of dream incorporation into waking behavior. Those responses are correlated with reported levels of involvement and self-defined types of the creative process. Greater involvement in creative process was significantly associated with greater incorporation of dreams into waking behavior. The reported types of creative outlet were divided for analysis between those with a creative product and those without product (experiential). The creative product grouping showed higher levels of reported dream incorporation into behavior than the experiential grouping, with both of these groupings reporting significantly higher levels of dream incorporation into waking behavior than the grouping reporting no creative outlet. Gender differences were found for both incorporation of dreaming into waking (significantly higher responses in females) and types of creative outlet (creative product significantly higher in females, experiential in males). In this study, level of interest in the creative process was positively correlated with reported level of dream incorporation into waking behavior. This study suggests that dreaming is likely to have a functional role in the creative process.     

Frequency of nightmares and gender significantly predict distressing dreams of German athletes before competitions or games

Effects of Creative Personality on EEG Alpha Oscillation: Based on the Social and General Creativity Comparative Study

The neural mechanism underlying creativity has been identified and confirmed by numerous studies. This current exploratory study compared the neural basis between social creativity and general creativity and explored the effect of creative personality on their neural basis by employing multiple regression analysis. The EEG activities of 34 participants were recorded during social or general creative tasks. The results indicated that a stronger alpha event‐related synchronization (ERS) was presented during the social creative task than during the general creative task. High creative personality individuals were found to exhibit higher event‐related desynchronization (ERD) only for the upper alpha band. Additionally, high creative personality individuals revealed no significant task differences regarding the alpha ERS. However, low creative personality individuals exhibited a stronger alpha ERS for social creative tasks than they did for general creative tasks. The current investigation could lead to new approaches for examining the brain correlates of creativity from different domains and their correlations with respect to creative personality.     

Nightmares and bad dreams: their prevalence and relationship to well-being

This study, for the first time, distinguishes between nightmares and bad dreams, measures the frequency of each using dream logs, and separately assesses the relation between nightmares, bad dreams, and well-being. Eighty-nine participants completed 7 measures of well-being and recorded their dreams for 4 consecutive weeks. The dream logs yielded estimated mean annual nightmare and bad-dream frequencies that were significantly (ps < .01) greater than the mean 12-month and 1-month retrospective estimates. Nightmare frequency had more significant correlations than bad-dream frequency with well-being, suggesting that nightmares are a more severe expression of the same basic phenomenon. The findings confirm and extend evidence that nightmares are more prevalent than was previously believed and underscore the need to differentiate nightmares from bad dreams.     

The Adaptable Mind in Design: Relating Personality,Cognitive Style,and Creative Performance

This study examined domain-specific relationships between creative personality traits, cognitive styles, and creative performance in design. Design students (n = 39) completed the Adjective Check List (ACL) and the Herrmann Brain Dominance Instrument (HBDI) to gauge personality and cognitive style, respectively. The ACL was scored using Domino's Creativity Scale (ACL-Cr) to identify creative personality traits. The sample also completed a design task that was evaluated for creativity using the Consensual Assessment Technique (CAT). Findings indicated that participants showing flexibility between cerebral, limbic, right, and left modes of thinking had significantly higher mean scores on creative personality than did those who exhibited a more entrenched cognitive style. Creative personality traits (ACL-Cr) significantly predicted creative performance on the design task. While cognitive style (HBDI) did not predict creative performance, flexibility between styles was significantly correlated to the creative personality. In sum, individuals exhibiting adaptable thinking appear to possess the flexibility necessary to design creatively and potentially transform the domain with original and imaginative solutions.     

I know how you felt last night,or do I? Self- and external ratings of emotions in REM sleep dreams

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