Sleep is increasingly understood as a local brain phenomenon, not just a whole-brain process, with different states of consciousness—wakefulness, sleep onset, light sleep, deep sleep, and REM sleep—able to occur simultaneously, leading to dissociative states. These are classified as physiological (daydreaming, lucid dreaming, false awakenings), pathological (sleep paralysis, sleepwalking, REM sleep behavior disorder), and altered (hypnosis, anesthesia, psychedelics). The article reviews the neurophysiology and phenomenology of these states, concluding that their study is important for understanding consciousness and treating neuropsychiatric diseases.
