Yeah, it's very specific. But definitely not real, and not from a movie. No trauma involved.

Yes, I have a lot of strange, vivid and interesting dreams. I "got in touch" with that side of my being during therapy in my early 30's... my therapist assigned "keeping a dream journal" as homework... almost 30 years later, I've never stopped. I think we remember our dreams better when we learn "how to remember" them.
