Well it was only really horrifying until I figured out what was going on. Actually it was one of the things that lead me to my field of science/study.

I mean, it still feels pretty terrible and all, but now I can appreciate it as one of those mysterious quirks of an organ I find utterly fascinating.

And I think I'd actually be more inclined to freak out if I were hallucinating and able to move as opposed to hallucinating and unable to move, so I feel worse for you, friend.
