Unexplainable Fear?

Read this:
I had a nightmare about the Inco Superstack. In it, Mr.**** made everyone walk along the 400 all the way from Toronto to Sudbury. It was very short though. Sudbury seemed to be only a KM or two away though. Once we were there, we were all standing on a VERY thin balance beam like trail over an impossibly deep ravine. Up ahead was this incredibly wide base. As wide as all of Toronto. I felt this incredible fear, not of falling, but of the Superstack. I felt like if I looked up and saw the Superstack’s full height, I would die. Mr. **** told everybody to look up. I refused, and he said if I didn’t he would push me into the ravine. I tried to run, but he grabbed me and pushed me off the trail into the ravine. I was careening out of control, and tried to close my eyes so I didn’t see the Superstack ahead of me. I didn’t seem to have any eyelids though, so I ended up almost seeing it. I just saw this bright light all of a sudden, and for a second I felt like I was on fire, but then I suddenly woke up. I am sure I would have done a movie-style bolt upright, if it weren’t for the fact that I didn’t remember the dream until now. This must have been my scariest nightmare in at least three months.

PS: The Inco Superstack is a tall smokestack in Sudbury. About the height of the Empire State Building actually. Nothing scary about it though.

EDIT: My teacher isn't called Mr.Bitch or anything. I just don't want anyone to know what class I am in, as that could help stalkers. Stupid, I know, but bleh.

This is like my worst nightmares. Either someone I love or me is about the go over the edge.

I hate heights with a passion.

The fear wasn't about the heights though. I love roller coasters in real life! It was about the smokestack.
