you were hanging out with rubbery in nighttime, you're sitting next with her on a bench waiting for someone, you notice her visible and I mean VISIBLE eyebags you decide to ask about it

"Oh it's nothing... Things happen when I'm asleep.. You don't wanna know what will happen..."

after a few minutes, she accidentally fell asleep you didn't mind about it until you hear something creeking creepily

her neck extended.

Oh no! You've encounter a yokai! What will you do now?
