There's this myth in my community, probably started by the fairly obscure sect many of the older folks follow, that after staying awake continuously for thirty days and thirty nights, your mind will momentarily be touched by the deity. I don't know the details, but there was something about a vision involving a mossy sepulcher and the eye of a wolverine. Even though I'm aware that it's probably bs like many of their practices (fish-entrail bracelets?), it has long made me curious about what staying up for so long would be like, mentally. And if the delirium were accompanied by some kind of spiritual revelation and infusion of transcendental energies, I would not say "no" to that either.
