cycles‚ each lasting about 90 minutes. During these cycles‚ we will experience 5 different stages of sleep- the first four being characterized as non-rapid eye movement sleep (NREM)‚ and the last stage being characterized as rapid eye movement sleep (REM). When human beings are awake‚ the electrical activity in their brain usually takes the form of fast‚ erratic brain waves. These waves are known as beta waves. During stage 1 of sleep‚ the brains electrical activity begins to change‚ with the brain

according to a study published in September 22 in Nature Neuroscience‚ people may be able to reimagine and reduce the power of fearful memories while they sleep.
