Your dream diary is getting to me. I dreamed I was visiting a museum that was in the UK but something to do with America (and no, not in Bath), which had displays in the basement but you had to crawl through a rather odd arrangement of beams and door to get to it, which I duly did, came back, and then was taken there again, only to discover that in fact if the doors and beams were folded back correctly, there was a small lift. No, I don't understand it either.
