Be nice for a long international flight. Flight attendants go around knocking anyone out who wakes up. Only sound on the flight would be the engines, the thwank of the pans on people's skulls, and that one psychopath who refuses to put on headphones while watching videos on his phone.
"Excuse me, sir?" "Yes?" *bonk!* Yeah, that'd be good.
Wasn’t there a Stephen King short story about this? Like they put everyone to sleep to go through some kind of teleport portal. But one guy stays awake (it’s always a guy) and the process sends him mad. Like, his consciousness gets stuck in there forever. Actually that does sound pretty good.
