The neurophysiological basis of self-awareness during sleep (lucid dreaming) is still poorly understood. Previous work suggested that transcranial alternating current stimulation (tACS) during sleep could increase dream self-awareness, but methodological flaws in those studies motivated a new investigation. In the current study, both tACS and a sham procedure were associated with signal-verified and self-rated lucid dreams, indicating that situational factors, rather than the stimulation itself, may be critical for inducing self-awareness during sleep.
