Lucid 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.

Lucid dreaming, where the dreamer knows they are dreaming, can be triggered in a lab by training people to associate the sleep laboratory with reflective awareness before sleep. In three studies with 101 participants, a morning nap followed verbal instructions and audio primes. Some conditions added immersive virtual reality rehearsal of the lab, haptic stimulation during REM sleep, or virtual reality with fake system errors. Across all conditions, 40-45% of dreams were rated lucid, and 11-32% were signal-verified lucid dreams. However, the extra virtual reality and haptic techniques did not increase lucidity compared to the basic lab training alone. This suggests that simply training people to recognize the lab context is a powerful method.

Lucid dreaming has mental and physical health benefits, but most induction techniques require extensive practice. A portable interactive prototype called LuciEntry was designed to help induce lucid dreaming using timed visual and auditory cues. Lab and field studies were conducted, and interview data revealed three themes. From these findings and design practice, seven considerations were derived to guide future lucid dream systems. The work aims to inspire further research into interactive technologies for altered states of consciousness.

Lucid dreaming—becoming aware that one is dreaming while continuing to dream—is a notable exception to the typically poor self-reflective consciousness during sleep. Once met with skepticism, it now receives increasing attention for its relevance to the neuroscience of consciousness. This review provides an overview of neuroscientific literature on lucid dreaming and discusses clinical and practical applications. Recent findings highlight lucid dreaming's emerging potential as a methodology for consciousness research within sleep science.

During retrieval of schema-based memories, the medial prefrontal cortex (mPFC) decouples from the default mode network (DMN), and the degree of this decoupling predicts memory performance. This suggests a demand-specific reconfiguration of the DMN supports schema memory. In a control condition relying on episodic memory, activity in the parahippocampal gyrus was positively related to memory performance. These results indicate dynamic reconfiguration of brain networks in response to task demands, with the mPFC decoupling for schema memory and the parahippocampal gyrus decoupling for episodic memory.
