When the Sleeper Wakes - Herbert George Wells - Google Books
George Fort Gibbs wrote The Sleeper Awakens,1941.
In Wells’ version, The Trance Chapter, someone reading or perusing the book, apparently realized the sleepless man burned out his neurons with the cocaine and was why he developed the state of cataplexy, portrayed in The Awakenings film, declaring the patients treatable by Dr. Oliver Sacks, only to regress to previous behavior. I doubt the aforementioned is treatable once the neurons are damaged, unless his state was hypnotically induced to afford the medical student something to study without objection.
