One summer in my teens, it was far too hot to sleep. We didnt have air conditioning so it was fans all the time. Couldn't sleep, then had to go to school the next days.
Went almost a week. Was seeing hallucinations like album covers moving their lips and talking to me. Crazy.
Then there was when Skyrim was first launched. Stayed up a few days.
I've taken to calling them "Species BATS", just because.
