It was an average day of school, nothing out the ordinary, you fall asleep in class whether it's normal for you, or extremely rare, you just felt tired today and couldn't bear staying awake to listen to a Teacher yap for an hour...

You wake back up, the sun shines through the windows like an early morning, everything is quiet, you feel well rested... The classroom looks evacuated, and the board says "IT'S A || APOCALYPSE", but the kind of apocalypse is scratched out.
