I'm the same as you. I can't stand to see other people doing it--pictures, movies, real life. Went to the circus last week and it was very scary--all I could think the whole time was that someone was going to lose their balance and fall. Most of them had nets but I think the lady that had the horses and also was hoisted into the air and did some "tricks" up there didn't. The one act that freaked me out the most was a couple that was walking upside down--way above the arena.

What causes the fear in me is when my sense of depth perception is disrupted abruptly. Like that picture over the side of the building. Rationally, I knew I wasn't or couldn't fall, but I momentarily lost sense of the depth of my field of vision. I recovered in seconds, but it is really a weird feeling. The photo looking straight down on the ship caused a similar reaction.
