Eyes move slowly under the eyelids, muscle activity slows down, and you are easily awakened. <br/> <br/>Stage N2 (Light sleep) – This is the first stage of true sleep, lasting from 10 to 25 minutes. Eye movement stops, heart rate slows, and body temperature decreases. <br/> <br/>Stage N3 (Deep sleep) – You’re difficult to awaken, and if you are awakened, you do not adjust immediately and often feel groggy and disoriented for several minutes. In this deepest stage of sleep, brain waves are extremely slow. Blood flow is directed away from the brain and towards the muscles, restoring physical energy. <br/> <br/>REM sleep <br/>REM sleep (Dream sleep) – About 70 to 90 minutes after falling asleep, you enter REM sleep, where dreaming occurs. Eyes move rapidly. Breathing is shallow. Heart rate and blood pressure increase. Arm and leg muscles are paralyzed.<br/> <br/>Then switches from N3 to REM and back until transition from REM to N3 to N2 to N1 to waking up, though mose people wake up from alarms and things directly from REM, N3, or N2</div></blockquote><br/><br/>thanks i knew it was something like that but had it all messed up told ya i talk bollucks half the time lol
