Dream recall is reportedly more common after propofol than after volatile anesthesia, but this may be due to delayed emergence or more amnesia after longer-acting volatiles. The electroencephalographic signs of dreaming during anesthesia and the differences between propofol and desflurane also are unknown. The authors therefore compared dream recall after propofol- or desflurane-maintained...

The ultradian NREM-REM sleep cycle and the circadian modulation of REM sleep sum to generate dreaming. Here we investigated age-related changes in dream recall, number of dreams, and emotional domain characteristics of dreaming during both NREM and REM sleep. Analysis of dream recall and sleep EEG (NREM/REM sleep) during a 40-h multiple nap protocol (150 min of wakefulness and 75 min of sleep)...

STUDY OBJECTIVES: The goal of the study was to seek physiological correlates of lucid dreaming. Lucid dreaming is a dissociated state with aspects of waking and dreaming combined in a way so as to suggest a specific alteration in brain physiology for which we now present preliminary but intriguing evidence. We show that the unusual combination of hallucinatory dream activity and wake-like...

A substantial proportion of returnees from the Iraq war have significant psychological symptoms related to war zone exposure, including high rates of post-traumatic stress disorder (PTSD), nightmares, and sleep disturbances. This pilot investigation examined the feasibility and efficacy of a promising cognitive-behavioral treatment (CBT) for nightmares, Imagery Rehearsal, combined with CBT for...

Many clinical, laboratory and non-laboratory studies have examined dream content reported by patients with schizophrenia but findings have been variable and inconsistent. Using both questionnaire-based measures and laboratory REM sleep awakenings, we investigated dream content in 14 patients with schizophrenia (mean age=25.5+/-3.2 years) under atypical antipsychotic medication and 15 healthy...

Research has shown that external stimuli presented during sleep can affect dream content, thus reflecting information processing of the sleeping brain. Olfactory stimuli should have a stronger effect on dream emotions because their processing is linked directly to the limbic system. Because selective olfactory stimulation does not increase arousal activity, intense olfactory stimulation is...

Dreaming has been a subject of cogitation since remote Antiquity. In ancient Greece, Socrates, Plato and Aristotle discussed about the meaning of dreams, concluding that the prevailing mistic and mythic concepts about them were incorrect. Instead, they thought that dreams were not provoked by spirits, ghosts or gods, which took over the mind to express themselves through dreaming. Aristotle[ 1...

Imagery rehearsal therapy (IRT) may help reduce residual nightmares and posttraumatic stress disorder (PTSD) symptoms in veterans after trauma-focused PTSD treatment. Fifteen male U.S. veterans with PTSD and trauma-related nightmares, who had not previously completed trauma-focused PTSD treatment, attended 6 IRT group sessions. No benefits were observed immediately posttreatment. At 3- and...

Dream recall is naturally a prerequisite for eliciting dream content. Therefore it is of importance to study factors (e.g., personality traits) that might affect dream recall because these factors might bias the content analytic findings in the field of dream research. The present findings indicate that different aspects of dream recall (dream recall frequency, dream recall detail, long-term...
