Dreaming is often characterized as lacking high-order cognitive (HOC) skills. In two studies, we test the alternative hypothesis that the dreaming mind is highly similar to the waking mind. Multiple experience samples were obtained from late-night REM sleep and waking, following a systematic protocol described in Kahan (2001). Results indicated that reported dreaming and waking experiences are surprisingly similar in their cognitive and sensory qualities. Concurrently, ratings of dreaming and waking experiences were markedly different on questions of general reality orientation and logical organization (e.g., the bizarreness or typicality of the events, actions, and locations). Consistent with other recent studies (e.g., Bulkeley & Kahan, 2008; Kozmová & Wolman, 2006), experiences sampled from dreaming and waking were more similar with respect to their process features than with respect to their structural features.

Here we describe a type of depolarising plateau potentials (PPs; sustained depolarisations outlasting the stimuli) in layer 2/3 pyramidal cells (L2/3PC) in rat prefrontal cortex (PFC) slices, using whole-cell somatic recordings. To our knowledge, this PP type has not been described before. In particular, unlike previously described plateau potentials that originate in the large apical dendrite of L5 cortical pyramidal neurons, these L2/3PC PPs are generated independently of the apical dendrite.

Narcolepsy is a rare, chronic neurological disorder characterized by a dysregulated sleep-wake cycle, with core clinical features including excessive daytime sleepiness (EDS), cataplexy, hypnopompic/hypnagogic hallucinations, and sleep paralysis. Several treatment options are available for the symptomatic management of narcolepsy, but they have limitations. Comorbidities of narcolepsy further limit the treatment choices.

While there is evidence of continuity between waking life and dream content, findings with regard to personality are questionable due to methodological issues. In addition, previous studies have used explicit measures, although one could assume that dream content, which is formed implicitly, should have a closer relationship with implicit measures of personality. We investigated how explicit and implicit measures of self-esteem are related to two possibly pertinent variables of dream content.

Although numerous individual factors influencing dream content have been explored, research on the link between sexual orientation and dreaming remains limited. This study examined this relationship among 119 German-speaking men (mean age = 31.97 years), including 55 homosexual and 64 heterosexual participants.

Nightmares are distressing dreams that evoke strong negative emotions, such as fear or anxiety, often leading to waking from sleep and subsequent sleep disruption. They are prevalent across various age groups, with significant psychological and physiological health implications. This review explores the nature of nightmares, distinguishing them from other sleep disturbances like night terrors and sleep paralysis.
