I think there's one called freakydreams.com, which, when you type an account of your dream into the interpreter, picks out words (such as rabbit, door, train, etc) and tells you what these elements in your dream are supposed to mean.

I don't know whether I entirely believe dream interpetation or not. I don't think they can tell the future or anything like that. I do think, though, they are a reflection of your emotions and perhaps what you think could happen to you, jumbled around with memories lurking in your subconcious and images you've seen or things you've imagined recently. That's my explanation for why dreams can be so weird, anyway.

I often have dreams about crashing or being in a natural disaster, but surviving. Maybe I'm subconciously always ready to spring into action when things go wrong and am determined to see it through? Who knows.
