Weird dream...

So I had a really weird dream last night. I was in some kind of swimming/deep sea program but I was trying to escape something (I think it was one of those water planes)...anyways, we had to swim in like this dome-type thing but there were sharks! And some guy was with me (don't know who...) and he was helping me escape. Also, there were these water obstacles we had to get over to reach safety. I don't really remember anything else about it...told ya it was weird!
