The commonsense view is that a lucid dream starts when the dreamer realizes that they are currently dreaming. The notion of realization, however, has been accepted at face value, with little consideration of whether the dreamer realizes that they are dreaming in the sense of actual reasoning, or if it is a mere epiphenomenon of lucid dream initiation. This article offers a solution to this...

Aim: To compare different β-adrenoceptor antagonists for the risk of reporting nightmare. Methods: The study involved two approaches: first, we investigated in VigiBase®, the World Health Organization Individual Case Safety Report (ICSR) database, the disproportionality between exposure to each β-adrenoceptor antagonists and reports of nightmares between 1967 and 2019. Second, in a...

Charles Dickens outlined a variety of manifestations of sleep and its disturbances, which were presumably related to his own and those of family and friends, also expressed in some of his characters. There are many reports of the dream-reality confusion through the anguished young Oliver Twist, the protagonist of the book of the same name. The virtual world of dreams is important for Dickens’...

In this concise review, we present an overview of research on dream recall/affect and of the hypothalamic-pituitary-adrenal (HPA) axis, discussing caveats regarding the action of hormones of the HPA axis (mainly cortisol and its free form, cortisol-binding globulin and glucocorticoid receptors). We present results of studies regarding dream recall/affect and the HPA axis under physiological...

Event-related potentials (ERPs) associated with the involuntary orientation of (bottom-up) attention towards an unexpected sound are of larger amplitude in high dream recallers (HR) than in low dream recallers (LR) during passive listening, suggesting different attentional functioning. We measured bottom-up and top-down attentional performance and their cerebral correlates in 18 HR (11 women,...

Study objectives: To test and extend Levin & Nielsen's (2007) Affective Network Dysfunction (AND) model with nightmare disorder (ND) image characteristics, and then to implement the extension as a computational simulation, the Disturbed Dreaming Model (DDM). Methods: We used AnyLogic V7.2 to computationally implement an extended AND model incorporating quantitative effects of image...

Based on the Social Simulation Theory of dreaming (SST), we studied the effects of voluntary social seclusion on dream content and sleep structure. Specifically, we studied the Compensation Hypothesis, which predicts social dream contents to increase during social seclusion, the Sociality Bias - a ratio between dream and wake interactions - and the Strengthening Hypothesis, which predicts an...

A previous study in military veterans with posttraumatic stress disorder (PTSD) and recurrent nightmares found a high prevalence of lucid dreaming (LD), the awareness while a dream continues that one is dreaming, and an “LD profile” characterized by frequent dream awareness and rare dream content control. Given the importance of the nightmare disturbance in PTSD, this study assessed with...

The currently best-supported psychological treatment for nightmares is imagery rehearsal therapy. The problem, however, is that not enough trained practitioners are available to offer this treatment. A possible solution is to conduct imagery rehearsal therapy in a guided self-help format. In the current study, 70 participants with nightmares according to the fifth edition of the Diagnostic and...
