BACKGROUND: The goal of this pilot study was to evaluate the effects of the cognitive-restructuring technique 'lucid dreaming treatment' (LDT) on chronic nightmares. Becoming lucid (realizing that one is dreaming) during a nightmare allows one to alter the nightmare storyline during the nightmare itself. METHODS: After having filled out a sleep and a posttraumatic stress disorder questionnaire,...

Dreaming is the mental activity of REM (and less commonly NREM) sleep.It is characterised by a perception of self, inner and outer world that is distinct from that of wakefulness.Neurophysiological and neuroimaging studies suggest that dreaming arises from activation of brainstem, thalamo-limbic and medial temporo-occipital areas and inactivation of dorsolateral prefrontal areas.Dream...

Sleep and dream research has recently been invigorated by convergent data from complementary neuropsychological sources such as brain-imaging studies of normal sleep, clinical investigations of dream disorders in brain-damaged patients and analyses of dream reports from healthy individuals. Here we show that by adopting a neuropsychological approach to dream phenomenology we can gain important...

Our neurobiological knowledge about human dream organisation results primarily from the study of Rapid-Eye-Movement (REM) sleep.In humans, functional neuroimaging techniques, using H 2 15 O or 18 FDG positron emission tomography (PET) and functional magnetic resonance imaging (fMRI), allowed the mapping of the regional cerebral activity during this sleep stage, which is dominated by the...

Dreaming has fascinated mankind since the dawn of history. This article focuses on the psychologically oriented research which has three major areas of interest: (1) a description of dreams (What do dreams look like?), (2) factors influencing dream content and (3) the effects of dreams on subsequent waking life. The following definition attempts to cover the consensus of the researchers in the...

Previous research regarding the relationship between habitual sleep duration and frequency of dream recall yielded conflicting results, whereas experimental manipulation of sleep duration showed a significant effect on dream recall. In this study analyzing both effects simultaneously, the findings from diaries kept by the 196 participants over 28 to 111 days indicated that intra-individual...

To examine whether there is a relation between nightmares and serum lipid levels. Fifteen subjects who met DSM-IV criteria for the diagnosis of nightmare disorder and 15 healthy control subjects participated in the study. We used an enzymatic colorimetric method for cholesterol and triglyceride determination. We measured high-density lipoprotien (HDL) cholesterol using the direct...

The threat simulation theory of dreaming (TST) () states that dream consciousness is essentially an ancient biological defence mechanism, evolutionarily selected for its capacity to repeatedly simulate threatening events. Threat simulation during dreaming rehearses the cognitive mechanisms required for efficient threat perception and threat avoidance, leading to increased probability of...

In a sample of 71 medical students, dream recall frequency was positively correlated with proneness to altered states of consciousness ( r = .26) measured by the State of Mind and Consciousness Questionnaire and dissociation ( r = .29) measured by the Dissociative Experiences Scale II. A regression analysis, however, yielded neither altered states of consciousness nor dissociation, sex, or age...

This longitudinal study tested the continuity hypothesis, which postulates that waking states and concerns are reflected in dreams. The relationship between dream content and negative waking affect was investigated both at fixed points in time and over a 6- to 10-year period. Twenty-eight participants completed measures of psychological well-being (PWB) and kept a dream log at two periods of...
