Patients with REM sleep behavior disorder (RBD) enact their dreams, leading to enhanced dream recall. They report more negative emotions in their dreams, recall retrospective nightmares more frequently, and often experience more aggressive dreams. This study aims to understand dream characteristics in REM sleep behavior disorder using both retrospective and prospective measures in a controlled...
Abstract Introduction Previous research found that nightmare proneness, a purported disposition to experience frequent nightmares, accounted for nightmare frequency independent of neuroticism and distress. However, these findings may have been the result of reduced reliability and content validity of the measures. The current study aimed to replicate these findings using established, lengthier...
Objectives Insufficient sleep leads to several short- and long-term physical and mental consequences. Yoga is a popularly known complementary health approach that maintains physical and mental health through asanas, meditation, and breathing techniques. Cyclic meditation (CM), derived from one of the Upanishads, is practiced by combining physical postures (asanas) with relaxation techniques....

Dear Editor, The Merriam-Webster Dictionary Online defines dreams as a succession of ideas, pictures, or feelings that happen while people sleep ( https://www.merriam-webster.com/dictionary/dream ). The Sleep Foundation describes a dream as ideas or images that come to mind while people are asleep; a dream may occur at any sleep stage, but rapid eye movement (REM) sleep is when dreams tend to...
In adults, nightmare disorder is related to sleep deprivation, drug consumption or abuse, or other comorbid sleep disorders such as insomnia or insufficient sleep syndrome. Behavioral treatment has solid scientific evidence in disorders such as insomnia and, more recently, parasomnias. The aim of the present study was to investigate the clinical effectiveness of a Brief Behavioral Telemedicine...
Objective When metacognition arises during rapid eye movement (REM) sleep, people experience lucid dreaming (LD). Studies on this phenomenon face different obstacles. For example, its standard verification protocol requires at least three types of sensors. We hypothesized that preagreed frontalis movements (PAFMs), as a sign of lucidity, could be seen on electroencephalography (EEG) during REM...

Introduction Systematic reviews and metanalyses have shown that mindfulness-based interventions can have positive effects on health, such as reducing anxiety, depression, and chronic pain. However, their effect on sleep-related outcomes is not yet well established. Sleep can be assessed subjectively (questionnaires, sleep logs, self-reporting) and/or objectively (actigraphy, polysomnography,...
Introduction Chronic nightmares are a common and disabling feature of posttraumatic stress disorder (PTSD) for which broadly effective treatments are still lacking. While imagery rehearsal therapy (IRT) demonstrates benefits for patients with idiopathic nightmares and some patients with PTSD-related nightmares, research indicates it may be less beneficial for veterans. Narrative therapy (NT) is...
Introduction Nightmare proneness, a trait-like disposition to experience frequent nightmares, has been strongly related to psychological distress. The aim of the present study was to examine if cardiac symptoms and hypothetically-related variables, nightmares, and perceived physical health could be used to differentiate nightmare proneness and psychological distress. Materials and Methods In...
Objective: Many people have dreams nightly and some maintain consciousness during dreams. Such dreams are referred to as lucid dreams (LD). During dreams, our speech correlates with facial muscle activity, which is hard to decode, but LD could solve this problem. The primary hypothesis of this study was that the facial muscles electric activity during LD corresponds to specific sounds....
Objectives: Meditation practices positively influence the neural, hormonal and autonomic systems. We have demonstrated that long-term practice of mindfulness meditation increases N3 and rapid eye movement (REM) sleep stages and bring efficient autonomic modulation during sleep. In the present study, the probable humoral correlation that could bring about these changes is evaluated. Material and...

Observation of episodes of sleepwalking and prolonged partial sleep paralysis in the same patient is a rare condition. We present a case of 42 years gentleman who presented with recurrent episodes of sleepwalking and prolonged incomplete sleep paralysis. He was on tablet divalproate 1000mg/day and tablet olanzapine 5mg/day in view of a psychotic episode that occurred 4 years ago....
Wakefulness involves diffuse activation of cerebral cortex through Ascending Reticular Activating System (RAS), which connects midbrain and pons to cortex through the thalamus and hypothalamus. RAS is primarily composed of the pedunculopontine tegmentum (PPT) & laterodorsal tegmentum (LDT) of pons, locus coeruleus nucleus (LC) and dorsal raphe nucleus (RN) which involves all classic...
The diagnosis of a nightmare disorder is based on clinically significant distress caused by the nightmares, e.g., sleep or mood disturbances. In order to understand nightmare etiology better empirical research should focus on studying factors that affect nightmare distress in addition to nightmare frequency. Overall, 2492 persons (1437 woman, 1055 men) completed the online survey. Nightmare...

ABSTRACT Sexual behavior can be associated with several stages of sleep, including both non-rapid eye movement and rapid eye movement stages of sleep. In narcoleptic patients, orgasmic cataplexy, or orgasmolepsy, and sexual hypnagogic hallucinations can be present. Although the association between narcolepsy and sexual behaviors has already been described, few reports describe the embarrassing...

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...
