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...
The August 2010 issue of Journal of Clinical Sleep Medicine (Vol. 6, No. 4) included an article suggesting treatment recommendations for adult nightmare disorder. Although we appreciate the work by the authors, we were left with three basic concerns about the methodology utilized and results found. First, works providing evidence for some of the treatments were not reported in the original...
Nightmares are a prevalent disorder leading to daily impairments. Two cognitive-behavioural self-help interventions--imagery rehearsal and exposure--recently showed short-term efficacy compared to a waiting-list and a group that recorded their nightmares. This paper reports the long-term results of the imagery rehearsal (n=103) and exposure (n=95) interventions. Participants were assigned...
Soldiers who play video games to varying degrees were solicited to fill out a survey on dreams and gaming. A prescreening filtered out those who were not soldiers, who did not game and who were suffering from various psychological problems in the last six months. The remaining soldiers filled out these inventories; general and military demographics, history of video game play, Emotional...
Számos személyiségjellemzőről bebizonyosodott már, hogy kapcsolatba hozható az álmokra való emlékezés képességével. Több kutatás irányult az alvásminőség és az álomfelidézés kapcsolatának feltárására is. Szintén sokakat inspirált az álom tartalmi jellemzői és az álmok felidézhetősége közti viszony megragadása. Mind ez idáig azonban nem került egy kutatás fókuszába sem az életminőség és az...
Motor activity in rapid eye movement (REM) sleep behaviour disorder (RBD) has been linked to dream content. Systematic and controlled sleep laboratory studies directly assessing the relation between RBD behaviours and experienced dream content are, however, largely lacking. We aimed to investigate whether a link can be established between RBD behaviours and dream content when both are...
Among sleep stages, awakenings from rapid eye movement (REM) sleep produce the greatest number and reported intensity of dream reports. Dreaming is a conscious state that lacks the insight and cognitive control typical of healthy waking but allows the remarkable emergence of coherent narrative, vivid visual imagery, strong emotion, and sometimes never-before-experienced elements. Similar to...
The need to study dreaming is the promise that it will unlock the mystery of psychosis and perhaps contribute to resolving the mind–body problem. A number of questions arise in the study of dreams. Can dreams be reliably measured? Do dreams reflect differences where we know psychological differences exist? Do dreams change when there is a change in the state of the dreamer? Do dreams change...
A number of differences between the dreams of schizophrenia patients and those of healthy participants have been linked to changes in waking life that schizophrenia may cause. This way, the "continuity hypothesis" has become a standard way to relate dreaming and waking experiences in schizophrenia. Nevertheless, some of the findings in dream literature are not compatible with the continuity...
The purposes of this study were: (1) to explore cancer patients' complaints of poor sleep, which often involve a combination of somatic symptoms and nightmares; and (2) to understand these sleep disturbances in the light of modern dream theories and intervention modalities. The literature search originated with several major articles (Revonsuo, 2000; Krakow & Zadra, 2006; Hobson, 2009) which...
Activity in the prefrontal cortex may distinguish the meta-awareness experienced during lucid dreams from its absence in normal dreams. To examine a possible relationship between dream lucidity and prefrontal task performance, we carried out a prospective study in 28 high school students. Participants performed the Wisconsin Card Sort and Iowa Gambling tasks, then for 1 week kept dream journals...
Dreams are a universal human experience and they form cultural themes in folk traditions and religious rituals, such as pilgrimages and dream incubation. Dreams and dream beliefs are important since they contain representations of interacting supernatural agents that have full access to information of strategic importance to humans. The relevance of dreams often relates to the dreamers'...
