I am afraid of heights, to an extent.
For example, I can be in a one hundred story building at the top floor, and I'll be just fine so long as I don't stand next to the window. (Because I do not trust the stability of the wall holding the window.)
Or, I can be on the second floor of the mall, but I won't stand next to the rail. (Afraid I'll get pushed over.)
I would be fine in a jet, because I would be (for the most part) in total control. Plus I could eject, and I would have a parachute.
...I guess I'm not really afraid of heights, just free-fall.
I'm SEMI afraid of the dark, but that's because I have poor eyesight and a very active imagination. So if it's dark, and I'm not wearing glasses, I see some crazy shit. One time, the shadow on the corner of my ceiling and my leftmost wall, I saw an enormous tarantula, and another one (shadow of my knee on the same wall) seemed like it was staring at me.
And I'm totally claustrophobic, just not so much as sword.
