This study focuses on a set of dreams related to the September 11, 2001 terrorist attacks and their aftermath, using content analysis and cognitive psychology to explore the interweaving of external public catastrophe and internal psychological processes. The study tests several recent claims in contemporary dream research, including the central image theory of Hartmann [Hartmann, E., & Basile,...
A committed interdisciplinarian, Kelly Bulkeley has customarily engaged with the phenomenon of human dreaming through a variety of academic lenses, from the neuroscientific to the psychological to the religious, often within one text.Dreaming in the Worlds Religions: A Comparative History does not represent a departure.It is in some respects, as the title would suggest, a relatively...
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,...
The aim of this review is to evaluate the effectiveness of cognitive behavioral therapy (CBT) on nightmare frequency and to determine which kind of CBT is the most effective treatment. A systematic literature search was carried out in PsychInfo and PubMed articles published on or before May 1, 2008. The inclusion criteria were: nightmare treatment study, use of nonpharmacological treatment, not...
The present study investigated the effects of socio-demographic variables on dream content in a representative sample. The analyses of 380 most recent dreams showed that almost none of the socio-demographic variables like age, gender, marital status, education, income, nor town (or city) of residence size was significantly related to general dream characteristics like dream length, bizarreness,...
This paper shows how the dream archive and search engine on DreamBank.net, a Web site containing over 22,000 dream reports, can be used to generate new findings on dream content, some of which raise interesting questions about the relationship between dreaming and various forms of waking thought. It begins with studies that draw dream reports from DreamBank.net for studies of social networks in...
Twenty-two veterans with posttraumatic stress disorder (PTSD) were assessed for trauma-related nightmares (NM) and non-nightmare distressed awakenings (NNDA) before and after treatment with the alpha-1 adrenoreceptor antagonist prazosin at an average bedtime dose of 9.6 mg/day. Ratings combining frequency and intensity dimensions of NM decreased from 3.6 ± 2.6 to 2.2 ± 2.4 (p<0.05), NNDA from...
Both neurobiological and cognitive psychological evidence suggests that dreams reflect the affective concerns and emotional balance of the dreamer. Moreover, there is increasing evidence for the thesis that dreams take part in the process of emotional regulation by creating narrative structures and new associations for memories with emotional and personal relevance and giving birth to a reduced...
SummaryMany studies have reported gender differences in dream recall. Data from 175 independent studies have been included in the analyses. Overall, estimated effect sizes in five age groups of healthy persons differed significantly from zero. Variables like measurement method and publication year did not affect the gender difference but age groups showed different effect sizes. The smallest...
The present study investigated the effects of sociodemographic variables on dream recall frequencies in a representative sample of 931 persons over 14 years of age. Analyses indicated that age, sex, and the size of the place of residence had small but significant effects: women and inhabitants of large cities tend to report dreams more often than men and residents of small towns. There was also...
Eleven healthy subjects, 9 females and 2 males aged 21-23, were submitted to all night polygraphic recording and awaken in REM (Rapid Eye Movements) sleep, randomly upon tonic or phasic REM. Immediately upon awakening subjects were asked about possible dreaming according to the standardized questionnaire. Seventy-seven dreams, i.e. 79% of all 97 REM awakenings, were reported and analyzed. There...
Studies on nightmare frequency have yielded inconsistent results. We compared the frequency of nightmares and bad dreams obtained with retrospective methods (annual and monthly estimates) and with two types of prospective measures (narrative and checklist logs). Four hundred and eleven participants completed retrospective estimates of nightmare and bad dream frequency and recorded their dreams...
The continuity hypothesis in its general form states that dreams reflect waking life: concerns, thoughts, and experiences (G. W. Domhoff, 1996; M. Schredl, 1999; I. Strauch & B. Meier, 1996). For example, athletes and sport students dream about sports more often than do psychology students, presumably reflecting their engagement in sport activities and sport theory (D. Erlacher & M. Schredl,...
Longer sleep duration should be related to dream recall (longer REM sleep), but previous findings regarding the relationship between habitual sleep duration and dream recall frequency have been conflicting, whereas experimental manipulation of sleep duration yielded a significant effect. The analysis of diaries kept by the 444 participants over 14 days indicated that intra-individual...
Dream questionnaires were completed by 28 young adults with autism spectrum disorder (ASD) participants. Seventy-nine typically developed individual served as the control group. In a subset of 17 persons with ASD and 11 controls matched for verbal IQ, dream narratives were obtained following REM sleep awakenings in a sleep laboratory. Questionnaires revealed that participants with ASD, compared...
Many clinical anecdotes and an experimental study have reported intensification of dreaming by the selective serotonin-reuptake inhibitors (SSRIs). However, no published neurochemical dream model invokes serotonin as a dream-promoting neuromodulator or accounts for serotonergic dream enhancement. An experimental study of normal volunteers showed that, although SSRI treatment decreased dream...

The purpose of this study was to investigate the effect of flunitrazepam, a benzodiazepine with strong hypnotic properties, on dream content. Eight normal subjects were studied in laboratory by the awakening technique, and the dream contents were rated by two judges according to nine scaled dimensions: unreality, participation of the dreamer, pleasantness, unpleasantness, verbal aggressivity,...
The aims of the present study were to examine the rate of nightmare disorder (ND) and to determine the levels of dream anxiety and subjective sleep quality in patients with borderline personality disorder (BPD). Another aim was to determine whether dream anxiety was associated with childhood trauma, dissociative experiences, and subjective sleep disturbance in BPD patients. Finally, the...
It has long been known that dream recall, along with various other features of dreaming, changes as a function of time of night. Yet the processes which might account for these time-dependent variations remain obscure. Here we assess the contribution of homeostatic and circadian factors to the generation of NREM mentation across the diurnal cycle. Assuming that previously reported time-of-night...
Nightmares are a prevalent mental disorder resulting in disturbed sleep, distress, and impairment in daily functioning. Elaborating on previous theoretical models for anxiety disorders, sleep disorders and dreaming, this study introduces a cognitive model of recurrent nightmares, the central element of which concerns representation of the nightmare’s repetitive storyline in the memory as a...
