Spiders. Not a fan. In fact I can't even look at pictures of them.
So what do I picture every damn time I go to bed at night?
Spiders running all over my sleeping body and one of them crawling into my ear. It would build a nest there and baby spiders would be born in my ear causing deafness and a lethal case of the oogies.
I sleep on my side and every night I make sure to cover my exposed ear because it's so freakin' likely to happen. (don't worry, I'm eye rolling at myself)
There just aren't enough flamethrowers in the world to deal with these 8 legged fear machines.
