EEG microstates reveal distinct network dynamics in lucid and non-lucid REM sleep

During lucid dreaming, the dreamer is aware they are dreaming. To identify brain network activity linked to this conscious experience, 39 sleep recordings (lucid vs. non-lucid REM sleep) from 8 lucid dreamers were analyzed using EEG microstate analysis. Microstates A and G dominated during lucid REM, while microstates B, C, and D dominated during non-lucid REM. These microstates were associated with emotional processing (A), visual processing (B), salience network activity (C), executive functions (D), and the default mode network (G). Results suggest lucidity involves increased self-visualization, metacognition, and executive processing, with decreased emotional processing and default mode network activity, indicating distinct network dynamics in lucid REM sleep.
