L'appel du vide (French)
Translates literally to "the call of the void".
The urge some people get to jump from high places when they encounter them, for example, when close to the edge of a cliff. The fear of heights comes not from fear of tripping and falling but the idea that one might suddenly be compelled to throw oneself over.
Nothing makes more sense than that. As irrational as it sounds. I hear it. I feel it. I feel it.
