What is a really random or uncommon phobia you have?

I for one, have this phobia of dropping things from high heights. I am not afraid of heights or anything, I am perfectly fine with them actually, seeing as I live in a 10 story building. It's just that, when someone's holding something in their hands and then suddenly sticks their hands out over the edge of the balcony, like a phone or something... And it's not limited to just that... just being near an edge while holding something is enough for me to break in cold sweat.

The odd thing is, I don't feel anything if the thing I'm holding is food :newlol

What about you?
