Isn't that weird how it sort of surprises your conscious mind? And the things that set it off? I noticed that it's the sound of hyperventilation for me--I actually almost fainted while not watching Hostel, because my friends were watching it and had the sound up enough that I started breathing in time to somebody's hysterical screams. They were puzzled when I had to get up from my book and lie down on the floor with my feet on my chair.

We think it runs in the family. Dad's got some stories of his own (he's proof that you can apparently get over it), and my brother is an urban legend at our old high school for being The Reason The History Teacher No Longer Shows Those World War I Slides From The Veterans' Hospital. (He's got a really specific trigger, too, which is knowledge I may use for evil someday.) And I have one other totally unconscious incident of my own on record, but it was in reaction to pain instead.
