Physiological variations hallucinations, lack of oxygen, orgasms (associated with feelings of pleasure) Psychological variations sensory deprivation, hypnosis, mindfulness meditation. Rhythms of sleep spent in cycles of 90 minutes approximately every 90 minutes we pass through five stages of sleep. These stages are associated with different brain waves (vary in frequency/amplitude) Awake and active eyes open, being attentive and responsive to the environment. Beta waves (high frequency, low amplitude), often irregular waves. Alpha waves relaxed/deep into meditation - (relatively high frequency, low amplitude), less frequent and more amplitude than beta waves, more regular than beta waves. Stages one & two - theta waves waves of larger amplitude, slow and regular, also observed during day dreams. Stages three & four the brain activity slows during deep sleep delta waves - waves of high amplitude, very slow and regular called.
