Sometimes when I'm up late at night and everyone else is asleep I get afraid that time has stood still except for me so I have to get up and check on people.

Brain damage. The idea of losing your sense of self or a piece of you just not existing anymore freaks me the fuck out. Hemispherectomies in particular. Like if the connections in your brain get spit does the other part of you brain have it's own personality trapped in a sort of hell completely disconnected from senses unable to communicate? Fuck that.

that thing where you hate holes, it literally makes me dizzy to look at it

This.

I'm also super paranoid about being pickpocketed. Whenever I'm around a large crowd where I don't know anybody, I put my wallet in my back pocket and keep my hand in that pocket until I'm away from the crowd. If I take it out, then I'll check that pocket like every minute.
