Something oddly relevant: quantum insomnia:

Of course that guy not being me or you, it is obvious that he is not a quantum insomniac, but there's a rather creepy thought: Today may be the day that you woke up for the last time in your life, and you'll remain awake forever, just because there will always be branch where you are awake, and you after a night's sleep is more different from you falling asleep, than you one second later, still awake. Good night. On second thought, I probably shouldn't joke like this here but for some reason I find that concept quite funny (and I don't believe in it for a second; it is very silly that QM would prevent you from falling asleep but won't prevent you from being cognitively impaired by insomnia, but i do fear that if i get insomnia, that may make me think of the MWI while my judgement is impaired, so hereby i'm trying to pre-commit not to think of MWI after more than 20 hours awake, which i really recommend to everyone here as well)
