Neurophysiological features of dream recall and the phenomenology of dreams: Auditory stimulation impacts dream experiences.
Consciousness and cognition July 1, 2025 Gulshan Kumar, Safoora Naaz, Nahida Jabin et al.
Dream recall is more frequent after REM sleep than N2 sleep. During dream recall, EEG beta activity increases, functional connectivity within the default mode network strengthens, and the medial frontal cortex activates, regardless of sleep stage. Auditory stimulation during sleep can influence the emotional content of dreams, suggesting that targeted memory reactivation may be possible. These findings help clarify how conscious experience arises during sleep.
