So there used to be this cartoon called Silverhawks, which was about these dudes who are partially made of metal and they can fly.

First dream I can remember, I was at the doctor and they wanted to give me a shot in my leg. I was really afraid of needles at the time, but suddenly I became a Silverhawk. The nurse was trying to stick the needle in my thigh, but my thigh was metal, so her plan was foiled.
