So, im aware this site isnt super trustworthy and I havent found the quote in google elsewhere,but maybe its in some french website
Anyways the quote is:"
In 1974, French sleep scientist Michel Jouvet studied a man suffering from a rare condition called Morvan’s Syndrome. Jouvet observed the 27-year-old man stay awake for four solid months. He never slept, but experienced vivid hallucinations for 20 minutes every night.

From this study, Jouvet came to the remarkable conclusion that most of the disorders people experience while going without sleep were not the result of lack of sleep but the result of the body’s sleep system trying to force them into unconsciousness. According to Jouvet, this case disproved the scientific consensus that sleep is a vital function.

Sleep… is “not necessary for life,” he wrote. “A man can read the newspaper, make plans on the future, play and win cards, easily find recent memories or old, learn a complex labyrinth and
lay all night on a bed, in the dark, without having sleep”
