Nightmares and cardiometabolic diseases in an adult population-based sample.
Journal of Psychosomatic Research May 14, 2026 Keyuan Liu, Geoffroy Solelhac, Nicola Andrea Marchi et al.
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...

1366 Optimal Management of Nightmare Disorder due to Multifactorial Etiologies in a Patient with Hypersomnia
SLEEPJ May 8, 2026 James R. Hall, Mercy Azubuko-Uduh, Naomi Ghildiyal et al.
Abstract Introduction Nightmares are usually associated with insomnia but rarely can arise from distinct and overlapping etiologies that can result in hypersomnia. The etiologies that need to be considered would be PTSD, acute stress disorder, nightmare disorder, depression, anxiety, medication/substance effect, narcolepsy, Idiopathic Hypersomnia. Rare causes are intracranial mass lesion, CNS...
1050 A Nightmare at the US-Mexico Border: Prevalence Associated with Acculturation, Sleep Health, and Mental Health – Data from the NoCHeS Study
SLEEPJ May 8, 2026 Alexei Kotov, Andrea Diaz-Pacheco, Patricia Molina et al.
Abstract Introduction Previous research has linked nightmares to anxiety, depression, and poor sleep quality. However, much less is known about how nightmares intersect with acculturation patterns and bicultural experiences in border communities. Understanding the connection between nightmares and acculturation is especially important in contexts where cultural identity, discrimination, and...
0104 Does the Menstrual Cycle Affect How Dreaming Shapes Emotional Memory and Reactivity?
SLEEPJ May 8, 2026 Jing Zhang, Andres Pena, Negin Sattari Barabadi et al.
Abstract Introduction Sleep supports emotion regulation by preferentially consolidating emotional memories while attenuating reactivity. We have shown that dream recall plays an active role by increasing negative over neutral memories and reducing reactivity. In women, fluctuating reproductive hormones across the menstrual cycle influence sleep features implicated in emotional memory, yet...
1048 Cortisol Awakening Response Predicts Nightmares in College Students: Evidence for Stress-Physiology Sensitivity in Disturbed Dreaming
SLEEPJ May 8, 2026 Elijah Nichols, Nancy Hamilton, Michele Okun
Abstract Introduction Nightmares are emotionally intense sleep disturbances linked to impaired emotion regulation and physiological arousal. Although stress sensitivity is theorized to increase vulnerability to nightmares, little research has examined whether specific HPA-axis indices, particularly the Cortisol Awakening Response (CAR), predict nightmare frequency in non-clinical young adults....
1200 Delivery of Cognitive Behavioral Therapy for Nightmares (CBT-N) in Primary Care Mental Health Integration Within the Veterans Health Administration
SLEEPJ May 8, 2026 Courtney J Bolstad, Constance H Fung, Lori L. Davis et al.
Abstract Introduction Nightmares are common, undertreated, and linked to various biopsychosocial issues in veterans. To address this clinical need, a provider training and consultation program in Cognitive Behavioral Therapy for Nightmares (CBT-N) was established in 2020 within the Veterans Health Administration (VHA). Program evaluation data indicate that clinicians perceive CBT-N to be...
0128 Emotion Regulation Approaches are Related to Nightmare Frequency and Nightmare-Related Impairment
SLEEPJ May 8, 2026 Andrew Meierotto, Garrett Baber, Nancy Hamilton
Abstract Introduction Dreaming is theorized to facilitate fear extinction, a type of implicit emotion regulation, whereas nightmares are thought to reflect failures in this regulatory process. However, it is not known whether the frequency of nightmares and associated functional impairment are related to explicit emotion regulation styles. This study examined associations between nightmare...
Associations Between Alexithymia, Negative Dream Emotions, and Nightmares: A Study Using Most Recent Dream Reports
Imagination, Cognition and Personality May 7, 2026 Yui Yoshioka
Alexithymia is characterized by difficulties in identifying and describing feelings and a tendency toward externally oriented thinking. This study investigated the relationship between alexithymia and dream emotions among 282 Japanese adults using the 20-item Toronto Alexithymia Scale (TAS-20), the Japanese version of the Mannheim Dream Questionnaire (MADRE), and a Most Recent Dream report...

Associations between stress and sensory sensitivity as risk factors for nightmares
International Journal of Dream Research May 4, 2026 Jamie Bueno, Petroc Sumner, Brittany Bueno
Nightmares are considered a hallmark symptom of post-traumatic stress disorder (PTSD). A risk factor for nightmares may be sensory processing sensitivity (SPS), a constellation of traits involving increased responsivity to sensory stimulation and emotion, and deeper cognitive processing. Here we tested whether this relationship between SPS and nightmares mainly occurs when stress or trauma are...
