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...

Incorporation of laboratory elements into dreams elicited in the sleep laboratory is a methodological problem, i.e., the measurement technique affects unwittingly the object of measurement (dream content). On a theoretical level, the occurrence of laboratory references, however, fits in the framework of the continuity hypothesis of dreaming. Reviewing the literature revealed that there is a...

The present study investigated the incidence of lucid dreaming within a Japanese university student sample. From 153 Japanese students 47% reported experiencing a lucid dream at least once and 19% were frequent lucid dreamers (frequency equal or higher than once a month). Dream recall frequency was significantly related to lucid dream frequency. In the Japanese sample the incidence of lucid...

Dream reports were collected from normal subjects in an effort to determine the degree to which dream reports can be used to identify individual dreamers. Judges were asked to group the reports by their authors. The judges scored the reports correctly at chance levels. This finding indicated that dreams may be at least as much like each other as they are the signature of individual dreamers....

Whereas the effect of sex and age on dream recall have been studied widely, socioeconomic status has rarely been investigated. However, two studies reported that higher socioeconomic status was related to greater frequency of dream recall. In the present sample of 612 Chinese students from three different schools, one elite (high socioeconomic status), one rural (low socioeconomic status) and...

Dreaming during anaesthesia is defined as any recalled experience (excluding awareness) that occurred between induction of anaesthesia and the first moment of consciousness upon emergence. Dreaming is a commonly-reported side-effect of anaesthesia. The incidence is higher in patients who are interviewed immediately after anaesthesia (approximately 22%) than in those who are interviewed later...

Previous questionnaire studies of parapsychological experiences have found significant interrelations between the experiences in question and dream experiences. In this study we present a replication of these relationships using a nationality of participants neglected in previous studies, a predominantly Spanish sample. A questionnaire was published in a Spanish New Age magazine. Four hundred...

This study investigated if dream content differences exist between male and female dreamers in England. One most recent dream report was collected from each of the 100 male and 100 female research participants during dream seminars and a dream research project held in England between 1990 and 2004. The Hall-Van de Castle System of Content Analysis (1966) was used to score each dream report....
