This article examines nightmare narratives collected as part of a person-centered ethnographic study of altered states of consciousness (ASCs) and supernaturalism in a mainland Puerto Rican community in the late 1990s. Utilizing a descriptive backdrop informed by cross-cultural studies of ASCs and highlighting the relevance of recent insights from the cognitive sciences of religion and from the...

There is debate in dream research as to whether ponto-geniculo-occipital (PGO) waves or cortical arousal during sleep underlie the biological mechanisms of dreaming. This study comprised 2 experiments. As eye movements (EMs) are currently considered the best noninvasive indicator of PGO burst activity in humans, the aim of the first experiment was to investigate the effect of low-intensity...

Laboratory research indicated lower dream recall in children compared to young adults. However, the sample sizes of these studies are very small and the findings regarding home dream recall in larger studies are conflicting. The present study compared home dream recall frequency of 558 children (mean age about 10 yrs.) with a sample of young adults (mean age about 23 yrs) and found a marked...

The interference hypothesis (Cohen, 1974; Cohen & Wolfe, 1973) was proposed to account for the difficulties in remembering dreams. Stimuli perceived on waking can either encourage activation of the waking brain or impair the transition from sleep to wake. The objective of the present study was to assess the validity of the interference hypothesis by discriminating between the natural decay of...

AIM: The aim of this study was to find out if the frequency of dream recall among neuropsychiatric patients on psychotropic drugs was significantly different from that of healthy individuals. METHODS: The study was done on 53 neuropsychiatric patients with different diagnoses who were on medication and 144 healthy individuals. The number of participants in each group who recalled their dreams...

Hartmann’s Boundary questionnaire was developed based on research regarding the personality of nightmare sufferers. Previous research showed that boundary thinness was not only related to openness to experience but also quite strongly to neuroticism. The aim of the present study was to develop a questionnaire measuring boundaries not related to neuroticism. The Boundary Personality...

The present study investigated the nightmare frequency of patients with insomnia. Patients reported more often nightmares, especially when overall dream recall frequency was statistically controlled. Moreover, nightmare frequency was related to the severity of insomnia complaints. It would be interesting to study whether specific techniques for treating nightmares (imagery rehearsal therapy)...

This study examined the applicability of imagery rehearsal therapy (IRT) to children with frequent nightmares. Eleven boys and 9 girls aged 9 to 11, with moderate to severe primary nightmares (1 or more per week for 6 months) and without posttraumatic stress disorder, were randomly divided into an imagery rehearsal treatment group (n = 9) or a waiting-list (n = 11) group. ANCOVA with repeated...

Summary. There is ample evidence that bad dreams and post-traumatic nightmares are a common consequence of exposure to traumatic events both among children and adults. The aim of the present study was to examine to what extent early-life maltreatment experiences are associated with dreams even many years later in adulthood. 37 patients suffering from primary insomnia recorded their dreams for...

The term "lucid dream" describes a dream during which the dreamer is aware of being in a dream while the dream is ongoing. Our investigation focused on the frequency of the lucid dream experience and its relationship to mental health, behavioural control (TPF; Becker, 1989), decision behaviour (EQS; Wolfram, 1982), and spatial abilities (3DW; Gittler, 1990). Data analysis of 89 subjects...

Neurobiologists and cognitive scientists are engaged in new efforts to establish the brain basis of consciousness. Progress in brain imaging and in quantitative EEG recording in humans and in unit recording in animals have all contributed to this progress. But progress has been limited by the relative poverty of the paradigms used in these studies, many of which do not take subjective...
