I can't be near open closets, I have two in my room and even having them closed makes me feel edgy.
It's the worse at night time, I'm not afraid of the dark or anything (I love horror movies and scaring myself) but with closets it's because I always get edgy thoughts about what's in the closet or beyond the closet (like in Narnia) it just becomes all I can think about and I don't like it. It probably makes sense to be less afraid/paranoid if it's open but for some reason it's just worse for me.
I guess it could be fear of the unknown or something.
P.S coming out of/being in the closet jokes aren't going to work because I can already see them coming, no sense in trying to pull one.
