Apocalypse Later

I had another end-of-the-world dream last night. I seem to have those often. But it's not usually nightmarish. Usually I'm looking for a way to survive and trying to save my friends and family. In this one, I don't remember the details but I do remember a huge tidal wave sweeping across the land. I'd like to think if I was really caught in a horrible storm, like the tsunami recently, I'd survive. I think everyone thinks they would, though. Is that weird?
