The problem is that people can't sleep when they want to, but if they are forbidden to do so, they can't help dropping off. So the method consisted of keeping your eyes wide open and fixing your gaze on some point of the bedroom wall. If by any chance you shut your eyes, hundreds of nasty little demons would pour out of the spot and eat you up. And you are absolutely not allowed to treat this as a joke.. According to Marc, you invariably fall asleep after ten minutes max, unless of course you replace the little devils with little fairies, which would stop you falling asleep at all.
