A dream is a succession of images, dynamic scenes and situations, ideas, emotions, and sensations that usually occur involuntarily in the mind during certain stages of sleep. Humans spend more than two hours dreaming per night, and each dream lasts around 5–20 minutes.

Dreams are involuntary successions of images, emotions, and sensations occurring during sleep, primarily in the REM (rapid eye movement) stage. Everyone typically dreams 3–6 times per night for 5–20 minutes each, yet 95% of these are forgotten upon waking. Dreams may process daily information, form memories, and help manage emotions.
