I haven't had a dream for years, not sure why. I've had a nightmare here and there, but a pleasant dream, none. My only guess would be dreams are your mind playing images of things you want or want to achieve. For me, I'm happy with what I'm doing, what I've achieved and have the girl of my dreams (literally), so I couldn't ask for more. My nightmares usually consist of losing something like Abbie, not being able to carry out a task I've studied and trained for so long to do, etc.
