What's the weirdest physical sensation you've felt?

The first time I got scintillating scotoma from a migraine. The preceding blindspot was really weird. I always thought a blind spot would just be a dark spot in your vision, but no. It was like that spot just didn't exist anymore. Like someone had used the 'pinch' filter in photoshop. and then the blind spot started flashing a full rainbow of colors before turning into a ring that grew bigger and bigger until it just left my field of vision. Didn't know what it was at the time. Thought I was in the process of going blind.

That, and...lol. the other day, my friend and I were driving somewhere down a bumpy road. First time ever I could actually feel my boobs bouncing. it was a bit embarrassing, even though he wasn't aware of it, but at the same time 'hey! cooolll! " :P
