Health and the human body - Psychology & behavior - REM sleep
During which sleep phase do especially vivid dreams occur most often?
Correct!
People can dream during different sleep phases. Especially vivid, visual, and emotional dreams often occur during REM sleep. REM stands for Rapid Eye Movement because the eyes move quickly beneath closed eyelids during this phase. The brain is relatively active while most skeletal muscles are strongly relaxed. The exact function of dreaming is still not fully understood scientifically.
