AP PSYCHOLOGY

Detailed explanation-1: -REM sleep happens about an hour to an hour and a half after falling asleep. REM sleep is when you tend to have vivid dreams.

Detailed explanation-2: -Dreaming. A majority of your dreams take place during REM sleep. However, REM is not the only stage in which dreams occur-that’s actually a common myth about sleep. That said, the dreams you experience in REM sleep are usually more vivid than non-REM sleep dreams.

Detailed explanation-3: -REM Stage R Stage R occurs about 90 minutes after you fall asleep, and is the primary “dreaming” stage of sleep.

Detailed explanation-4: -Rapid eye movement (REM) sleep, or stage R, usually starts about 90 minutes after you fall asleep. Brain activity increases, your eyes dart around quickly, and your pulse, blood pressure, and breathing speed up. This is also when you do most of your dreaming. REM sleep is important for learning and memory.

Detailed explanation-5: -Subjects awakened from REM sleep recall elaborate, vivid, hallucinogenic and emotional dreams, whereas subjects awakened during non-REM sleep report fewer dreams, which, when they occur, are more conceptual, less vivid and less emotion-laden.
