Lucid dreams – dreams in which the dreamer is aware that is dreaming – most frequently occur during REM sleep, yet there is some evidence suggesting that lucid dreaming can occur during NREM sleep as well. By conducting a sleep laboratory study on lucid dreams, we found two possible instances of lucidity during NREM sleep which are reported here. While lucid dreaming during NREM sleep seems to...
While dreaming amputees often experience a normal body image and the phantom limb may not be present. However, dreaming experiences in amputees have mainly been collected by questionnaires. We analysed the dream reports of amputated patients with phantom limb collected after awakening from REM sleep during overnight videopolysomnography (VPSG). Six amputated patients underwent overnight VPSG...
Comparing the phenomenology, neurochemical pathology, and psychopharmacology of hallucinations and dreaming is limited by the available data. Evidence to date reveals no simple correspondence between the two states. Differences in the phenomenology of visual hallucinations and the visual component of dreams may reflect variations in visual context acting on the same underlying mechanism - the...
Study objectives: Evidence supports the use of cognitive behavioral therapies for nightmares in trauma-exposed individuals. This randomized clinical trial replicated a study of exposure, relaxation, and rescripting therapy(ERRT) and extended prior research by including broad measures of mental health difficulties, self-reported physical health problems, and quality of life. Additionally,...
Az álom- és éber világunk közötti kapcsok megtalálása számos kutatót inspirált már. Jelen cikkben egy olyan saját kutatásunkat ismertetjük, melynek célja az álmodás kontinuitás-elméletének empirikus vizsgálata és a teória pontosítása. A kontinuitás-elmélet szerint az álmok hű tükrei életünknek, személyiségünknek, gondolatainknak és a minket körülvevő környezetnek. A teória azonban meglehetősen...
Dream is a state of consciousness characterized by internally-generated sensory, cognitive and emotional experiences occurring during sleep. Dream reports tend to be particularly abundant, with complex, emotional, and perceptually vivid experiences after awakenings from rapid eye movement (REM) sleep. This is why our current knowledge of the cerebral correlates of dreaming, mainly derives from...
Several independent lines of research in neurobiology seem to support the phenomenologically-grounded view of the dreaming brain/mind as a useful model for psychosis. Hallucinatory phenomena and thought disorders found in psychosis share several peculiarities with dreaming, where internally generated, vivid sensorimotor imagery along with often heightened and incongruous emotion are paired with...
Different theories have been put forward during the last decade to explain the functional meaning of sleep and dreaming in humans. In the present paper, a new theory is presented which, while taking advantage of these earlier theories, introduces the following new and original aspects: • Circadian rhythms relevant to various organs of the body affect the reciprocal interactions which operate to...
To explore associations between dream recall, gender, sleep, perceived stress, and creativity in a large sample of adolescents. In adults, women report a higher frequency of dream recall than men. Moreover, increased awakenings seem to increase dream recall, whereas low sleep quality is associated with low dream recall. In addition, there is some evidence that dream recall is associated with...

PURPOSE: To evaluate morning dream recall frequency and content in patients with temporal lobe epilepsy (TLE). METHODS: Fifty-two patients with pharmacoresistant TLE submitted to a written dream diary during five consecutive days and continuous video-electroencephalographic (video-EEG) monitoring. A matched control group of 41 healthy subjects completed the same diary at home. The number of...
