Abstract Background Approximately 5% of people suffer from nightmares at least every 2 weeks. One cognitive behavioral intervention for recurrent nightmares is imagery rehearsal therapy (IRT), in which individuals recall, modify, and rehearse a less distressing version of their dream. Objective This randomized controlled trial evaluated the efficacy of a web application called “DreamMend” as a...

Lucid dreaming (LD) is a state of conscious awareness of the ongoing oneiric state, predominantly linked to REM sleep. Progress in understanding its neurobiological basis has been hindered by small sample sizes, diverse EEG setups, and artifacts like saccadic eye movements. To address these challenges in characterizing the electrophysiological correlates of LD, we introduced an adaptive...

Abstract Background Since people with nightmares rarely seek help, low-threshold interventions and self-help methods are needed. Among different treatment approaches for nightmares, imagery rehearsal therapy (IRT) is the method of choice. Objective In the current study, the authors tested whether IRT is also effective when applied in a short version, within the scope of a single session of...

Dreams in which the dreamer is aware of the dream state (lucid dreams, LD) are difficult to induce in naïve subjects in-laboratory. Recently, Stumbrys and Erlacher (2014) used a combination of existing induction techniques together with a self-developed experiment protocol and achieved comparatively high LD induction rates. In this study, we simplified their methodology slightly and repeated...
