Document Summary

Subjective experience your own personal experience. Consciousness is a wave of beta waves. Circadian rhythms a cycle in biochemical, physiological and behavioral processes of living entities. Alertness lower level right when we wake up. Core body temperature drops when we are sleeping. Suspension of sensation not aware of the external world. Elimination of voluntary activity can have movement but it is not voluntary. Awake and alert, awake and drowsy (alpha waves), stage 1: thetawaves, stage. 2: thetawaves and spindles, stage 3: deltawaves, stage 4: mostly deltawaves, These four stages go through a cycle of about 90 minutes. Infants are sleeping a lot - 16 hours a night. Common dreams - flying, naked in a crowd, not prepared, being chased, dying, falling. 64% of dreams we record are negative dreams. 18% of dreams we record are positive. Twice as many aggressive dreams than friendly ones. Dreams are stories waking brain weaves about neural activity evoked during rem sleep.
