Dreams are so strange.

Last night I had the most vivid dream. I was staying in a hotel room next to Bill and Hillary Clinton (and one of their mothers). The room I was staying in was very nice, but when I walked in there were a few things leftover from the previous guest (keys, watch, sunglasses, wallet). At this point I was suspicious. Checking the closet, it turned out that the previous guest had not checked out, and was missing. From here the dream got even stranger, with me hiding around the hotel from a guy was out to get me (not sure of me, or something to do with the previous guest). Occasionally I dream about elevators and going up and down, being very afraid that the elevator is going to crash into the first floor. This dream was no different. I saw the Clintons once during the dream (and their mom), but the dream wasn't really about them. I wonder where all this comes from?
