The only dreams I remember on waking nowadays are lucid ones. I had awful nightmares as a kid and apparently learned how to get myself out of them (wake up) or alter them, out of sheer desperation. Sometimes I "get stuck" watching them, like a movie, where I can't change them but I can pull the plug and wake myself if they go somewhere I don't want them to.
