I usually don't have nightmares, but I will (semi) regularly have dreams where bad things happen to me (like having to re-take all of my college courses from a technicality, excessive financial troubles, or being thrown in jail for something strange). When I'm having a good dream, I seem to notice it whilst dreaming somehow choose to wake myself.
On a funnier note, my sister called me several months ago because she had dreamed that I was hurt or killed, and she wanted to make sure I was ok...but she didn't call until several days afterwards.
