The relationship between the dreamed body and the physical body remains an open question in sleep and dream research. This study examined whether somatosensory stimulation applied during REM sleep modulates the corresponding dream content under controlled conditions. Using a within-subject design, we compared three stimulation modalities-electrical muscular, galvanic vestibular, and haptic...
Abstract Study Objectives Sensory stimulation during rapid eye movement (REM) sleep has been proposed as a method to induce lucidity, yet most approaches rely on distal sensory modalities such as light and sound. We explored whether bodily stimulation targeting the muscle and vestibular systems differentially influences dream incorporation and lucid awareness during REM sleep. Methods 28...
Abstract Lucid dream (LD) induction using external sensory stimulation has most commonly relied on distal cues such as lights or auditory signals, with mixed success rates. In this study, we investigated whether more direct bodily stimulation targeting the muscle and vestibular systems could influence LD induction. We compared electrical muscle stimulation (EMS) and galvanic vestibular...
Abstract Lucid dreaming (LD), during which the dreamer is aware that they are dreaming, is frequently induced in laboratory settings by delivering sensory cues during rapid eye movement (REM) sleep. These cues should be incorporated into ongoing dreams and can trigger reflective awareness. This approach relies on the continuity between waking experiences and dream content. In sleep...
