I had a dream last night that I was in a car accident. It was pretty scary: my car slipped down a hill and flipped over. I was upside down, hanging from the seatbelt, and part of the roof/door was crushed in against my left arm. I was frightened, because I didn't know how to get out, and I was all alone. I thought my arm was broken. I've never broken a bone before, so I don't really know what it feels like. I remember thinking in the dream, "So this is what a broken arm feels like. If it is indeed broken."
(I've always joked that I have bones of steel, because they never break. But it hurt quite a lot - in my shoulder, upper arm, and even down into the little bones with which you wiggle your fingers.)
I woke up, and there was a cat sleeping on my arm.
