Strange beliefs

What's the weirdest thing that you at least somewhat believe in?

For me, it's probably gnomes.  You don't have to believe me, but I've seen them around 3am.  My friend and I used to ride in the bed of my dad's truck while he threw papers for his paper route.  It seemed to happen in the fog or mist.  Just really small things running by, but there was definitely a triangle shape on top, like one of their hats.

I fully believe they have a really nice set up underground.  They steal TV's and computers and random machines to take apart, and probably anything that's fun.   I imagine it being like a big rec room/workshop/man cave sort of place.
