I wish I could have more dreams like that, honestly. They're always the most interesting [instead of the standard "I'm in an ordinary setting but something weird/illogical is happening" that I usually get] and those "stories" always feel so much more compelling than if I was just reading a book or watching a movie.
Oh, and I'll expound a bit on my dream. It involved zombies [ugh, I know], but they were ECOLOGICAL zombies instead of the normal biological kind. There was weird plant stuff everywhere, including mutant plants that attacked people. The main character was a girl who became infected, but not zombified. Also, she was apparently a cyborg of some kind, but I'd probably cut that out if I actually wrote the full story.
