Suppressing unwanted thoughts can lead to an increased occurrence of the suppressed thought in dreams. This is explainable by the ironic control theory, which theorizes why the suppression of thoughts might make them more persistent. The present study examined the influence of thought suppression on dream rebound, dream distress, general psychiatric symptomatology, depression, sleep quality and...
OBJECTIVE: Sleep disturbances are a core and salient feature of posttraumatic stress disorder (PTSD). Pilot studies have indicated that combined cognitive-behavioral therapy for insomnia (CBT-I) and imagery rehearsal therapy (IRT) for nightmares improves sleep as well as PTSD symptoms. METHOD: The present study randomized 40 combat veterans (mean age 37.7 years; 90% male and 60% African...
Objective: Dreams enacted during sleepwalking or sleep terrors (SW/ST) may differ from those enacted during rapid eye movement sleep behavior disorder (RBD). Methods: Subjects completed aggression, depression, and anxiety questionnaires. The mentations associated with SW/ST and RBD behaviors were collected over their lifetime and on the morning after video polysomnography (PSG). The reports...
Dreams create new stories out of nothing. Although dreams contain themes, concerns, dream figures, objects, etc. that correspond closely to waking life, these are only story elements. The story itself weaves these mnemonic items together in a manner far more novel than a simple assemblage or collage, producing an experience having a life-like timeframe and life-like (if often bizarre and...
Sleep related symptoms of depression include sleep fragmentation, early morning awakening, decreased rapid eye movement (REM) sleep latency, increased REM density, and more negative dream content. Most tricyclic antidepressants (ADs) increase total sleep time and decrease wake time after sleep onset, while many selective serotonin reuptake inhibitors (SSRIs) have an opposite effect. However,...
Nightmares are intense and unpleasant dream experiences that characterize approximately 4 percent of the adult population at least on a weekly basis. Nightmare frequency is often co-morbid with other mental complaints; however, recent results indicate that nightmare disorder is independent from waking mental dysfunctions. Nightmare disorder is intimately related to poor subjective sleep...
A scientific study of consciousness should take into consideration both objective and subjective measures of conscious experiences. To this date, very few studies have tried to integrate third-person data, or data about the neurophysiological correlates of conscious states, with first-person data, or data about subjective experience. Inspired by Morel's invention (Casares, 1940), a literary...
Study objectives: Nightmares are disturbing mental experiences during sleep that usually result in abrupt awakenings. Frequent nightmares are associated with poor subjective sleep quality, and recent polysomnographic data suggest that nightmare sufferers exhibit impaired sleep continuity during nonrapid eye movement (NREM) sleep. Because disrupted sleep might be related to abnormal arousal...
Bereavement and its accompanying psychological response (grief) constitute potent experiences that necessitate the reorganization of cognitive-affective representations of lost significant attachment figures during both wakefulness and dreaming. The goals of this preliminary study were to explore whether the dream content of 77 adults with complicated grief (CG) differed from that of a...
Study objectives: Many studies have reported a positive association between sleep problems and suicidal ideation. Some prospective studies in the elderly have shown that insomnia is a risk factor for suicide death after controlling for other depressive symptoms. However, hypotheses to explain how this risk is mediated have not previously been assessed. We tested the hypothesis that insomnia...
Nightmares can cause great suffering as they disturb sleep, affect daily functioning and overall well-being. They are associated with psychopathology like anxiety disorders, more specifically posttraumatic stress disorder (PTSD), psychosis, personality pathology, suicide risk, and substance abuse [1,2]. Two to five percent of the general adult population suffers from one or more nightmares a...
The percentages of successful dream recall vary depending on whether the participants were awakened from REM sleep (about 80% recall) or NREM sleep (about 50% recall). The question as to whether this difference is explained by less dreaming during NREM sleep or sleep state-dependent memory processes cannot answered easily. The present pilot study was designed to test whether high recallers can...
Nightmares are defined as dreams with strong negative emotions that result in awakening. Overall, the findings of the present representative survey (N = 915) indicate that nightmare frequency decrease with age and living in urban areas are associated with heightened nightmare frequency. Longitudinal studies are needed to clarify how age affects nightmare frequency because the findings of...
The history and literature of the Roman Empire is full of reports of dream prophecies, dream ghosts and dream gods. This volume offers a fresh approach to the study of ancient dreams by asking not what the ancients dreamed or how they experienced dreaming, but why the Romans considered dreams to be important and worthy of recording. Dream reports from historical and imaginative literature from...
I propose a narrative fabrication thesis of dream reports, according to which dream reports are often not accurate representations of experiences that occur during sleep. I begin with an overview of anti-experience theses of Norman Malcolm and Daniel Dennett who reject the received view of dreams, that dreams are experiences we have during sleep which are reported upon waking. Although...
In what sense is dreaming real to people of different cultures? How do they come to conclude that dreaming is real, and how do they use dreams to expand their knowledge and control of real events? The reader is introduced to dream anthropology and shown that there are universal patterns to how dreams are experienced, expressed, and used by societies. The distinction between monophasic and...
This paper addresses claims that dreams can be a source of personal insight. Whereas there has been anecdotal backing for such claims, there is now tangential support from findings of the facilitative effect of sleep on cognitive insight, and of REM sleep in particular on emotional memory consolidation. Furthermore, the presence in dreams of metaphorical representations of waking life indicates...
Studies in cognitive psychology showed that personality (openness to experience, thin boundaries, absorption), creativity, nocturnal awakenings, and attitude toward dreams are significantly related to dream recall frequency (DRF). These results suggest the possibility of neurophysiological trait differences between subjects with high and low DRF. To test this hypothesis we compared sleep...
Recent studies in sleep and dreaming have described an activation of emotional and reward systems, as well as the processing of internal information during these states. Specifically, increased activity in the amygdala and across mesolimbic dopaminergic regions during REM sleep is likely to promote the consolidation of memory traces with high emotional/motivational value. Moreover, coordinated...
Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) is a condition characterized by repeated episodes of airway obstruction during sleep, causing intermittent asphyxia and sleep fragmentation. The goal of this study was to assess dream content analysis before and during the first night of treatment for OSAHS using Continuous Positive Pressure (CPAP). We included 38 patients diagnosed using...
