An expert consensus panel reviewed treatment manuals for cognitive behavioral therapies for nightmares (CBT-N) tested in randomized clinical trials with adults. The panel developed guidelines for standardized implementation and terminology of CBT-N, addressing patient symptom presentations appropriate for treatment and components such as session length, relaxation training, stimulus control, sleep efficiency training, sleep hygiene, nightmare exposure, nightmare rescripting, and imagery rehearsal of rescripted dreams. The recommendations aim to clarify confusion caused by unstandardized nomenclature and implementation nuances, and are intended to be revised as new research evidence emerges.

People who believe that external forces control their lives (external locus of control) report having lucid dreams more often, but only if they already identify as lucid dreamers. Among 348 young adults surveyed, those who identified as lucid dreamers experienced lucid dreams about once a month, whereas non-lucid dreamers had them less than once a year. The relationship between external locus of control and lucid dreaming frequency was significant only for self-identified lucid dreamers. The authors suggest that individuals who feel a lack of control during the day may use lucid dreaming to regain a sense of agency.

The Nightmare Disorder Index Chinese Version (NDI-CV) shows good psychometric properties for measuring nightmare impact in Chinese adolescents. Among 6,014 adolescents who completed the NDI-CV along with measures of nightmare distress, sleep quality, insomnia, daytime sleepiness, anxiety, and depression, the questionnaire demonstrated strong internal consistency with a Cronbach's α coefficient of 0.876. Test-retest reliability was assessed in 423 adolescents after a 2-week interval, with a correlation coefficient confidence interval of 0.675-0.977. The findings indicate the NDI-CV is a valid and reliable instrument for assessing nightmare disorder in this population.

About 7.4% of nurses met full criteria for probable nightmare disorder, and 43.9% had partial or subthreshold symptoms, based on a new self-report measure called the Nightmare Disorder Index (NDI). The NDI showed good reliability and validity. Nurses with nightmare disorder had significantly worse psychosocial functioning—including higher posttraumatic stress, depression, anxiety, and stress—than those with subthreshold symptoms, who in turn had poorer functioning than nurses with no nightmares. The findings suggest that nightmares are common among nurses and are linked to poorer mental health, supporting increased screening in high-risk healthcare workers.
