Summary
AI-generated from the abstractLucid dream induction using external sensory stimulation has often relied on lights or sounds, with mixed success. This study tested whether direct bodily stimulation—electrical muscle stimulation (EMS) and galvanic vestibular stimulation (GVS)—could induce lucid dreams. Twenty-eight participants completed two morning naps: one with stimulation during REM sleep and one with sham control. EMS and GVS did not increase stimulus incorporation. Lucidity rates were high in both EMS conditions, suggesting baseline lucidity, cognitive training, and expectations played a role. However, GVS significantly increased externally rated lucidity and DLQ questionnaire scores compared to control, indicating that galvanic vestibular stimulation can enhance dream lucidity.

Abstract
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 stimulation (GVS), each combined with a two-week cognitive training protocol including dream journaling, reality checks, and association training. Twenty-eight participants (14 per group) completed two counterbalanced morning naps: one with stimulation (STIM) during REM sleep and with one sham-stimulation control (SHAM). EMS and GVS stimulation did not lead to increased incorporation of the stimulus. Lucidity rates were high in both EMS conditions, highlighting the substantial role of elevated baseline lucidity in induction studies, cognitive training, and expectation effects. In contrast, GVS stimulation significantly increased externally rated lucidity and DLQ questionnaire scores compared to control. Overall, the findings indicate that galvanic vestibular stimulation can increase dream lucidity. Future work should further examine the mechanisms by which vestibular stimulation influences dream awareness and its potential role in lucid dream induction. Abstract Figure
