Whatever functions sleep performs, they must be so fundamentally important that they far outweigh the obvious vulnerability associated with being asleep this means we might as well cross another theory of sleep off the list, too the origins of rem sleep particularly bother researchers like libourel. Hobson and mccarley proposed activation-synthesis theory in 1977 their theory on the function of dreaming came from research that recognized the brain stem was activated during rem sleep hobson and mccarley used synthesis to refer to the brain's attempt to interpret the random activity and make sense of it. In 1953, a student at chicago university called eugene aserinsky and his adviser nathaniel kleitman discovered what's now known as rem sleep they found that two of the most famous psychiatrists in history, sigmund freud and carl jung, both had interesting theories about dreaming even though.
