Reoccurring dreams?

Ooh, that makes sense. Well...It's scary as all hell when it happens.

Well, outside of that there's this other dream I've had where there were area's of the world that had started to snow unexpectedly before suddenly getting so cold that it instantly froze everything it came in contact with. It was odd, because you could actually visibly see it coming. Some people and I were trying to run from it, and others around us as we ran were actually frozen in what they were doing. We started running through this tunnel, and could see frost appearing on the walls of the tunnel as we ran. In the last dream I had about it, the frost had started to edge ahead of us before I woke up. In a previous dream, we actually froze to "death", though I think we were revived somehow. Can't remember.

Sounds like some movie I've seen before, now that I think about it.
