Dream of an unfamiliar House and the search for Self

"I was in a house that I knew was supposed to be mine, but it didn't look like my real house. I was walking around trying to find a bedroom. I don't know why I needed it. I just remember feeling like I was supposed to be there. There were too many rooms. I would open one door and find another hallway behind it. At one point I found a room with all my old things in it. Clothes, some books, even a few things I thought I had thrown away years ago. Then I heard someone downstairs. I thought it was my mother, so I went down to see. Nobody was there. The front door was open, though, and I could see rain outside. I went back upstairs and suddenly the house seemed much bigger. I couldn't find the room with my things anymore. I wasn't really scared. Mostly I was annoyed and confused. I kept thinking, "I live here, so why can't I find my own room?" Then I woke up before I figured it out."
