The stream of human consciousness persists during sleep, albeit in altered form. Disconnected from external input, the mind and brain remain active, at times creating the bizarre sequences of thought and imagery that comprise "dreaming." Yet despite substantial effort toward understanding this unique state of consciousness, no reliable neurophysiological indicator of dreaming has been...

In general, dreams are a novel but realistic simulation of waking social life, with a mixture of characters, motivations, scenarios, and positive and negative emotions. We propose that the sharing of dreams has an empathic effect on the dreamer and on significant others who hear and engage with the telling of the dream. Study 1 tests three correlations that are predicted by the theory of dream...
The Dream Catcher test defines the criteria for a genuine discovery of the neural constituents of phenomenal consciousness. Passing the test implies that some patterns of purely brain-based data directly correspond to the subjective features of phenomenal experience, which would help to bridge the explanatory gap between consciousness and brain. Here, we conducted the Dream Catcher test for the...
The diagnosis of a nightmare disorder is based on clinically significant distress caused by the nightmares and, therefore, empirical research should focus on studying factors that affect nightmare distress in addition to nightmare frequency. Overall, 2056 persons (1212 woman, 844 men) completed the online survey. A reliable 6-item scale measuring beliefs about nightmares was developed. The...
Study objectives: To examine the efficacy of imagery rehearsal (IR) combined with cognitive behavioral therapy for insomnia (CBT-I) compared to CBT-I alone for treating recurrent nightmares in military veterans with posttraumatic stress disorder (PTSD). Methods: In this randomized controlled study, 108 male and female United States veterans of the Iraq and Afghanistan conflicts with current,...
Lucid dreaming, knowing one is dreaming while dreaming, is an important tool for exploring consciousness and bringing awareness to different aspects of life. We present a proof-of-concept system called Lucid Loop: a virtual reality experience where one can practice lucid awareness via biofeedback. Visuals are creatively generated before your eyes using a deep learning Artificial Intelligence...
OBJECTIVE Childhood adversity figures prominently in the clinical histories of children and adolescents suffering from a panoply of physical, mental or sleep disorders, including posttraumatic stress disorder. But the nature and prevalence of early adversity in the case of idiopathic nightmare-prone individuals have received little study. We characterize the types and frequencies of...
Background: Sexual abuse victims often experience symptoms of post-traumatic stress disorder (PTSD), including sleep disturbances. Objective: To investigate whether or not characteristics of sexual abuse are associated with sleep disturbance, and to explore whether correlates of sleep disturbance are distinguishable from those of PTSD symptom severity. Method: Forty-four adult sexual abuse...
Lucid dreaming refers to the phenomenon of becoming aware of the fact that one is dreaming during ongoing sleep. Despite having been physiologically validated for decades, the neurobiology of lucid dreaming is still incompletely characterized. Here we review the neuroscientific literature on lucid dreaming, including electroencephalographic, neuroimaging, brain lesion, pharmacological and brain...
