The human mind releases certain frequencies of brain waves during different stages of the sleeping cycle, when monitored by an EEG (electroencephalogram). The brain releases Beta waves while the human mind is awake and also during REM (rapid eye movement) sleep. REM sleep is typically the fourth stage of sleep and occurs every ninety minutes throughout the night. There is clinically no difference in brain function during REM sleep and being wide awake. However, this makes dreaming as real as reality to our minds.
