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'...

Under the assumption that dream recall is a peculiar form of declarative memory, we have hypothesized that (1) the encoding of dream contents during sleep should share some electrophysiological mechanisms with the encoding of episodic memories of the awake brain and (2) recalling a dream(s) after awakening from non-rapid eye movement (NREM) and rapid eye movement (REM) sleep should be...

Dreaming pertains to both REM and NREM sleep. However, frequency and regional specific differences in EEG activity remains controversial. We investigated NREM and REM sleep EEG power density associated with and without dream recall in 17 young subjects during a 40-h multiple nap protocol under constant routine conditions. NREM sleep was associated with lower EEG power density for dream recall...

From Joseph in the book of Genesis to the 2010 blockbuster Inception, dreams have been a source of fascination. The attraction seems to derive, in part, from their bizarreness. Indeed, it is rare to hear someone muse that “I had the craziest wakefulness last night.” But we are also compelled by the allure that dreams are imbued with meaning or that they reveal something about our psyche....

If both waking and dreaming consciousness are functional, their de-differentiation would be doubly detrimental. Differentiation between waking and dreaming is achieved through neuromodulation. During dreaming, without external sensory data and with mesolimbic dopaminergic input, hyper-cholinergic input almost totally suppresses the aminergic system. During waking, with sensory gates open,...

Study objectives: To conduct a systematic investigation on the prevalence, correlates, and familial aggregation of frequent nightmares in children, and to scrutinize the associations between frequent nightmares and parent-reported behavioral and mood problems in children. Design: A cross-sectional study was conducted by collecting the data on sociodemographic, sleep, behavioral, and...

Many studies have reported gender differences in nightmare frequency. In order to study this difference systematically, data from 111 independent studies have been included in the meta-analysis reported here. Overall, estimated effect sizes regarding the gender difference in nightmare frequency differed significantly from zero in three age groups of healthy persons (adolescents, young adults,...

Emerging evidence supports the notion of disrupted sleep as a core component of Posttraumatic Stress Disorder (PTSD). Effective treatments for nighttime PTSD symptoms are critical because sleep disruption may be mechanistically linked to development and maintenance of PTSD and is associated with significant distress, functional impairment, and poor health. This review aimed to describe the...

Increasing evidence supports the clinical view that alexithymia is associated with disturbed dreaming. However, a consistent, replicable pattern of relationships between alexithymia and different dreaming components has not yet been identified. Groups of sleep-disordered outpatients (N 580; 46.0 13.2 years) and nonclinical controls (N 145; 22.9 4.2 years) were administered the Toronto...
