I have a fear of buildings with a really, really high ceiling. It scares me, i have dreams about it where i fall up to the ceiling or something. What's really scary is when i dream about a ceiling that never seems to end. I have a fear of looking up at really tall buildings, where i feel like i'm going to fall down if i look all the way up at it. When I'm up in a really high place, I feel a lot more comfortable looking down than looking up. Looking up is scary.
