When I was a kid, I was afraid of pictures. Paintings, photos, you name it. I had a feeling that they were watching me, judging me. If they are realistic, that's double points.
Mirrors, too, stories of it being a parrel universe where doppelgangers live ready to take me.
Dolls, of course. After watching Chucky, I can never look at them the same way.
Public bathrooms. I still don't like them, but I thought someone would murder me there as a kid. It's always so dark and ominous.
I was a very troubled child.
