Explanation

Polyphasic sleep refers to sleeping multiple times in a 24-hour period, as opposed to monophasic sleep (once per day). The most common form involves taking several short naps throughout the day instead of one long sleep session. This can reduce total sleep time to 2-5 hours daily. Options A and C describe sleep stages and dreams, while D is irrelevant.
