Lets see...
First of all, I have zombie dreams, too (or I have had them, I can't remember a dream since last year or so), but I like them.
Why?
I always know they are dreams and/or have a shotgun. Whenever I know it's a dream, I can do whatever I want. I especially like using telekinesis-like jedi powers and always try to use them once I wake up (never works... or does it? *twilight zone theme song here*)
Second, I can remember several dreams I have had; I have had a dream set in the tanker from Far Cry (like the 2nd or 3rd mission) where I was caught, but I grabbed a gun(from one of the bad guys) and threaten to shoot the bad guys, but then the bad guy said, "Time out!" and was replaced with William Shatner. I then woke up.
In another dream I remember I was at a beach, I fell in the water, and sank like a rock. Wasn't scared, because I could breathe underwater. I landed on a ledge where above me was a vertical cliff going out of sight, and below was a vertical drop-off into nothingness. I walked along on this little ledge I was on, and saw a lobster sitting there. I often site this as proof that dreams actually are in color, because the lobster was bright red like it had been boiled.
Last one, I was sitting next to the ocean on the lawn of my Grandparents' house, looking out to sea. I blinked and suddenly it was night where it had been day. I blinked again and the time changed again, always to the opposite of what it had been. I thought that was strange.
That's all for now, if I think of any more, I'll put them up.
