It's a blind spot

I do this in the shower. I imagine a snake will come up through the drain. xD

It's a actually more likely that a rat would

Same.

I imagine spiders crawling up my butt. Enjoy your toilet time everyone ;)

This has happened

I've been paranoid ever since I saw snakes on a plane

I always imagine a tarantula is inside the bowl (like in that Australian public toilet gif) and that it will bite my dick

Nope!, don't want to imagine that

I have this fear too but instead of biting, I scared it will crawl up my kitty
