52 validation analyses across 6 datasets, 148 subjects, and 1,267 awakenings. No dataset-stage combination showed evidence of above-chance generalization after bootstrap testing. Dataset identity dominates predictive variance (74.5%). All code and data publicly available.

Abstract Introduction Nightmare Disorder (ND) is a prevalent sleep disorder linked to nocturnal and daytime impairments. Image Rehearsal Therapy (IRT) shows moderate effects, and evidence for other psychological interventions, including eye movement desensitization and reprocessing (EMDR), remains scarce in adults with idiopathic ND (IND). Methods This case study explored EMDR therapy's...
Abstract: A dream's context and the dreamer's individual history, culture, and language, create a significant matrix for dreamwork. When analyzing the dream of a patient from another culture, we may not understand the associations of the dreamer, not only because we cannot discuss the imagery and feelings aroused by the dream, or because we are unaware of the cultural references, but also...

Nightmare proneness and neuroticism are strongly related constructs which differentially predict variance in nightmares, yet their empirical distinctiveness remains unclear. The current study examined relationships among nightmare proneness, neuroticism, and nightmares in 774 university students. Principal axis exploratory factor analysis indicated that nightmare proneness and neuroticism items...
Nightmares, which are associated with various biopsychosocial issues, are common and often undertreated among veterans. To address the demand for Cognitive Behavioral Therapy for Nightmares (CBT-N) in the Veterans Health Administration (VHA), experts have trained mental health clinicians in its delivery. Program evaluation data show positive clinician perceptions of CBT-N but reveal...
Abstract Dream recall varies substantially both between individuals and from night to night within the same individual. Although nocturnal awakenings are thought to facilitate the encoding and later retrieval of dream experiences, it remains unclear whether dream recall is shaped primarily by awakening frequency or by more specific awakening characteristics, including duration, sleep stage, and...
Nightmares can trigger stress responses and lead to insufficient or poor-quality sleep, which are associated with cardiometabolic diseases (CMD) and their risk factors. However, research on the association and underlying mechanisms between nightmares and CMD in the general population remains limited. Data from three follow-ups of the CoLaus|PsyCoLaus study (Lausanne, Switzerland). Frequent...
