I don't have that - but I do have the urge to fling myself off high buildings if I'm ever up one. Horrible. I wonder what on earth that is all about?
My friend's dad, who's afraid of heights, fears he's going to jump off high places -not fall. Come to think of it, I have the similar urge, and I think it could be that the idea of jumping down voluntarily is easier to bear than the idea of just falling.
Anyway, I'm also afraid that I'll toss myself in front of train/tube if I don't concentrate enough (as to resist this).
And to get back to the topic, I remember when staying in St Petersburg four years ago, my local friend warned me of "vampires" that lurk in the tube (or metro, as it is called there). "Psychic" vampires make you jump into tracks and "energetic"(??) vampires suck your energy and make you fall down, I was told.
Maybe my friend had been smoking smothing, dunno, but he left me wondering whether there are similar stories somewhere.
Oh, and before someone asks, I don't know why these "vampires" are called vampires. Maybe it's just faster to say than "those weirdos that always hang around metro station".
Errr...lost my point, lost myself, sorry...
