I had one of those ultra-realistic dreams once where I was diving, but the dive site was Disneyland (specifically - Main Street a la Escape from LA), and it was all about 100 feet underwater. In my dream I was swimming through the buildings thinking, "This isn't right..."
Heck, maybe with global warming that dream will come true one of these days =)
Oh! And I just had one last night that was pretty bizarre. Some of my dive buddies and I were diving on a wreck (the wreck was like a research vessel / cruise ship), trying to recover some evidence of what had happened to cause it to sink. General consensus was that it was a seamonster of some sort, and we were trying to recover a towed camera housing that had gotten snagged on the wreck. We had a cable that we were snaking through the wreck to attach the camera to, but it snapped and we couldn't get the camera back out. Turns out it didn't really matter, because the camera didn't have any film in it and wouldn't have been much use anyway.
At some point in the dream, I was diving outside of the wreck and on voice comms with one of my dive buddies. This real weird fish kept swimming up and rubbing against me, and in my dream I was asking my dive buddy what kind of fish it was. He told me "Well... it lives in rocks - must be a rockfish" I think one of my cats must have been rubbing against me in real life, because this fish was real cuddly and soft...
My weirdest dream ever was that I was a chicken, playing basketball inside of a bar with Brittney Spears and Shaq. Analyze that, rofl.
I love bizzaro dreams!
