Submarine Dream

Just realised I never posted about this really, really odd dream I had the other day. Basically, I was on a submarine, and I was diving with this other guy and we got into a fight while we were swimming around, and he went a bit deep and the pressure killed him, but I could withstand the pressure better and so it didn't kill me. And then everyone was blaming me for the fact that he was dead (including myself). Then for some reason I was in English Lit and everyone was pretty hostile to me but Martin was asking like if it was all ok and telling me that it wasn't really my fault.
