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.     

Ordinary and Recurrent Dream Recall of Active, Past and Non-recurrent Dreamers During and After Academic Stress

The role of stress in the onset and frequency of recurrent dreams was investigated by comparing dream recall of students undergoing naturalistic stress conditions. Thirty nine students in active, past and non-recurrent dream groups (n = 13) recorded frequency of nights per week involving overall and recurrent dream recall in the week prior to mid-term examinations and in a neutral study week in second semester. Self-report measures of everyday hassles and uplifts, anxiety and positive and negative affect experienced during these conditions were also collected. Anxiety and negative affect were reported as significantly higher in the pre-examination week. Overall the groups reported dreams on significantly more nights in the pre-examination week than the post examination week. Recurrent dream nights increased during the stress week for the active recurrent dream group but there was no change in recurrent dream recall for the other groups. These findings are consistent with theories that the experience of emotional stress is a critical factor in the onset and persistence of recurrent dreams.     

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.     

Personality and Dream Recall Frequency: Further Negative Findings

On the basis of previous findings of dream recall frequency being associated with thin boundariness and sensitivity we assessed the association between DRF and variables that appear related to these two measures. Data from 93 participants (47 males, 46 females, mean age 21.3 yrs., SD = 3.5) show that dream recall frequency (DRF) correlates marginally with neuroticism (r = .20) and interrogative suggestibility (r = .21), the latter result indicating that DRF obtained by questionnaire may be subject to demand bias. DRF had very low correlations with various other personality variables (need for cognition, personal locus of control, hypochondriasis, morningness-eveningness), and with narrative memory, confabulation of narrative memory, and habitual sleep length. DRF correlated positively with POMS elated (-depressed) for males (r = .31) but negatively for females (r = –.19), this significant difference in correlations may be due to sex differences in DRF in response to stress. The frequent findings of small or nonsignificant correlations between DRF and personality are discussed in terms of similar low correlations in personality psychology, but we conclude that DRF is usually sampled adequately, and that the results of no simple relationship with personality (except boundariness, creativity, and positive attitude towards dreams) are therefore robust and may indicate that dream recall is mainly determined physiologically.     

Individual Differences in the Range of Sensory Modalities Experienced in Dreams.

The present study investigated the relationship between the recalled frequency of sensory modalities experienced in dreams and waking imagery abilities. Five hundred thirty-one undergraduate students completed 4 imagery ability tests and a dream recall questionnaire containing a question on the frequency of experience of the sensory modalities in dreams. A k-means cluster analysis of the Dream Sense Modality Scale indicated that the participants fell into 3 groups: the major modalities group, whose dreams were entirely visual, auditory, and kinesthetic; the all modalities group, who experienced all sense modalities in dreams; and the no modalities group, whose dreams were without sensory content. The participants' scores on the imagery tests in the 3 groups showed significant intergroup differences. The all modalities group showed the highest levels of ability in evoking vivid imagery and controlling visual imagery and the most frequent use of visual imagery compared with the other two groups.

Reading books about dream interpretation: Gender differences.

The vast variety of books on dreamwork and dream interpretation suggests that a considerable percentage of the general population is interested in reading these books. Empirical research in this area is relatively scarce. The present representative survey (N = 2,019) indicated that about 8% of the general population have read about dream interpretation in order to learn more about their dreams, with women reading about dream interpretation more often than men. This gender difference was not explained by differences in dream recall frequency. In addition, single people as well as people with high nightmare frequencies read about dreams more often. Future research should focus on the possible benefits of reading about dream interpretation. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Working with Dreams in Psychotherapy: The Therapists' Perspective

129 therapists completed a 70-item questionnaire about working with dreams in psychotherapy. Almost all therapists (92%) worked with dreams in psychotherapy at least occasionally. Therapists reported that 15% of clients had brought dreams into therapy during the past year. Therapists engaged more in exploratory than insight- or action-oriented activities when working with dreams. They were more likely to work on dreams with clients who had troubling dreams or who were interested in working on dreams, but were unlikely to work on dreams with schizophrenic or psychotic clients. Those clinicians who were more likely to work with dreams had more training, higher estimated dream recall, more positive attitudes toward dreams, and did more personal dream work than clinicians who were not likely to work with dreams.     

Rehearsal of dreams and waking events similarly improves the quality but not the quantity of autobiographical recall.

Salient dreams are often discussed and ruminated upon over time, especially when they feature in dream work or therapy. The present study investigated the effects of rehearsal over time on dream memories, as compared to memories for waking experiences. Participants were instructed to complete a dream and waking episodic event diary over two weeks. A rehearsal group (n = 27) were instructed to read through their reports after recording them. A control group (n = 28) were instructed not to look at their reports. A surprise recall task demonstrated that rehearsal reduced significantly the detail of dream, but not waking event, reports. It maintained episodic richness for dreams. Furthermore, rehearsed dream and event reports corresponded significantly more closely with original reports than controls. These data indicate that while rehearsal may not increase dream recall over time, it may influence the phenomenology of memories that are subsequently recalled, such that a rehearsed memory is subsequently recalled, rather than the original experience.

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.

Client Reactions to Working With Dreams in Psychotherapy.

A questionnaire about working with dreams was given to 95 clients in ongoing psychotherapy. Results indicated that clients who discussed dreams in therapy (68%) had more positive attitudes toward dreams, higher dream recall, and more therapist encouragement for talking about dreams than clients who did not. Clients reported that therapists used more exploratory than insight or action dream-related activities. The outcome of the dream session was positively related to the therapists' encouragement of dream work and dream-related activities used. Clients who had not discussed dreams in therapy indicated that they had not because there was not enough time in sessions to work on dreams or it had never occurred to them to talk about their dreams in therapy.

Interest in dream interpretation: A gender difference.

Although several studies reported a significant effect with regard to the gender difference in an interest in dreams, the generalizability of these studies is limited because mainly students were recruited as participants. In this study, gender differences with regard to interest in dream interpretation as an indicator of interest in dreams in general have been demonstrated in a representative sample. There was, however, a significant age-gender interaction, indicating that interest in dreams might not be a potent variable for explaining gender differences in dream recall. In future studies, the course of interest in dreams over the life span and any associated gender differences should be investigated using carefully designed scales.

Facilitating dream recall in Chinese people.

The aim of this study was to examine the frequency of dream recall in Chinese people and to develop nonintrusive procedures to facilitate dream recall. Guidelines for remembering dreams (dream recall instructions) were established based on a review of the existing literature on dream recall and its associated factors. The efficacy of the dream recall experience was explored using this procedure in neurologically healthy individuals. One hundred seventy Chinese participants were included in the study: 100 received the dream recall instructions, and 70 did not. The recall instructions were shown to be effective in triggering dream recall in the participants. (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.     

Explaining the gender difference in dream recall frequency.

A recent meta-analysis showed a substantial and robust gender difference in dream recall frequency of medium effect size, that is, women tend to recall their dreams more often than men. The question arises as to what factors might explain this difference. Two previous studies indicate that interest in dreams plays an important role. The present study found a significant effect of frequency of nocturnal awakenings and interest in dreams on the gender difference in dream recall frequency. In addition, neuroticism and depressive mood were associated with the gender difference on the aspects of a dream recall scale and interest in dreams. Longitudinal studies are necessary to validate the present findings, especially regarding their causality. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The effects of a two-week reflection-intention training program on lucid dream recall.

Previous research in the field of lucid dreams has produced several techniques which are claimed to be a means of inducing lucid dreams, but there have been only a small number of reported studies which have evaluated their effectiveness. The present study investigated the effects of one of the most promising of these, the reflection-intention technique, which is specifically designed to increase the frequency of dream and lucid dream recall. The sample here consisted of 20 participants whose frequencies of normal dream recall and lucid dream recall were recorded before, during and after a two week training program by using a dream questionnaire and a dream journal: A one-way repeated measures analysis of variance showed a significant increase in both dream recall frequency (F2,38 = 22.09, p2,38 = 5.96, p     

Dream Recall Frequency, Attitude Towards Dreams and Openness to Experience

The question whether personality dimensions explain the interindividual differences in dream recall frequency has often been investigated by dream researchers. The present findings confirm previous research which has shown that traits such as openness-to-experience and thin boundaries correlate substantially with dream recall frequency. However, correlation coefficients are small and are much larger if attitude towards dreams or a scale measuring different aspects of dream recall are considered. Thus, future studies should consider the differentiation between items measuring dream recall and related aspects and items measuring attitudes towards dreams. Schonbar's life-style hypothesis should be revised slightly: not dream recall frequency but attitude towards dreams and the way to deal with dreams are part of a broader life style.     

Boundary Questionnaire Results in the Mentally Healthy Elderly

The Hartmann Boundary Questionnaire was administered twice, with six months in between, to 61 Swiss subjects over 60 years of age taking part in an investigation into the effects of dream-telling on five variables: well-being, sleep quality, sleep duration, dream recall and dream tone. In addition, dream epoch, i.e., the age of life of the dreamer as perceived in the dream, was recorded for those who told dreams. In addition to this study group in which the members told dreams there were two control groups. Those in the first control group were asked about well-being and sleep quality but not about dreams or dreaming, while those in the second control group were additionally asked how many dreams they had retained, how frequently they had occurred and about the dream tone (pleasant/unpleasant). All study participants were given the Hartmann Boundary Questionnaire at the beginning (pre-test) and again at the end of the six month study period (post-test). The retest reliability was high (r = 0.872 for the whole sample). We report here the relationships obtained between the questionnaire scores and age, group membership, gender and the number of dreams that were retained over a 26 week testing period. No significant correlations were found for age, group membership or dream recall. There was, however, a small, significant boundary score difference between women and men for the pre-test, indicating thinner boundaries for women, but this difference was no longer significant in the post-test.     

The Dreams of Blind Men and Women: A Replication and Extension of Previous Findings

Drawing on a sample of 372 dreams from 15 blind adults, we present two separate analyses that replicate and extend findings from previous studies. The first analysis employed DreamSearch, a software program designed for use with dream narratives, to examine the appearance of the five sensory modalities. It revealed that those blind since birth or very early childhood had (1) no visual imagery and (2) a very high percentage of gustatory, olfactory, and tactual sensory references. The second analysis found that both male and female participants differed from their sighted counterparts in the same ways on several Hall and Van de Castle (1966) coding categories, including a high percentage of locomotion/transportation dreams that contained at least one dreamer-involved misfortune. The findings on sensory references and dreamer-involved misfortunes in locomotion/transportation dreams are interpreted as evidence for the continuity between dream content and waking cognition.     

Dream content: Reflections of the emotional and psychological states of earthquake survivors.

This study investigated dream narratives as reflections of the emotional and psychological states of earthquake survivors. Dreams and dreams imagery have reportedly been affected by the emotional and psychological trauma that the dreamer goes through. Dream narratives and dream content ratings used in earlier studies were utilized in this study. Narratives and content ratings were obtained from a sample of 27 volunteer survivors of the October 8, 2005 earthquake in Pakistan (Azad Kashmir area) and 27 volunteer controls from similar demographics. Three independent raters judged the dream narratives and dream content ratings. The judges rating were highly congruent (86.05). Findings revealed that the survivor group had more vivid, unpleasant, horrifying, and hostile dreams compared with the control group. However, there were no significant gender differences. The data suggest that a closer study of dreams can be used to understand the underlying trauma for effective interventions. In addition, interesting emergence of recurrent dreams was seen, which will be independently studied in future. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
