I had the bulletproof dreams too. I also used to have dreams often in which I could fly or jump really high. Those were always a blast.
I don't dream much these days, or if I do, I've forgotten them by the time I wake up. . .
I think one of my weirdest had me driving a car through someone's really big intestines. I think I was only 8, and didn't know what intestines would really look like. . . so they were blue in my dream.
