  9. Stages of Sleep and Brain Waves Alpha waves - brain waves that indicate a state of relaxation. Relaxed but awake: Alpha waves Theta waves - brain waves indicating early stages of sleep. Stage 1: Theta waves appear Light sleep; person may claim to still be awake Hypnogogic sensations may occur (floating, falling) and can be incorporated into real memories Hypnogogic = sensory experiences without sensory stimuli Hypnic jerk – knees, legs, or whole body jerks Stage 2: Sleep spindles (brief bursts of rapid brain activity) Asleep but may respond to some events, such as ringing phone Sleeptalking may occur
