A Fear of Tripping on a Sidewalk, Falling Straight Down, Causing my Nose to Puncture my Brain and Kill Me:Yes, this really belongs in your "Wazzhuh" category! I think I can explain a little bit... You know that feeling you get sometimes as you're falling asleep and it's like you're falling and you wake up with a start? Combine that with learning once in science class that if hit a certain way in the nose, a bone will go into your brain and instantly kill you (it's even some martial arts move). So, alas, I'm afraid of falling flat on my face and instantly dying from the puncturing of my brain by a nose bone! Similarly, I fear getting toenails ripped off tripping too. These aren't debliitating though, they just come to my mind sometimes and make me shiver, especially if I start to trip.
