The umbrella That wouldn't stay Open

"I dreamed I was walking somewhere I didn't recognize, carrying an umbrella even though it wasn't raining. The street was crowded, but nobody seemed to notice me, and I remember feeling like I was supposed to be somewhere else. I kept trying to open the umbrella, but it wouldn't stay up. Every time I pushed it, it folded back down like it was stuck. I remember getting frustrated, but not really upset—just tired of trying. At some point I was standing in front of a house I didn't recognize, and the door was open. I don't know whose house it was, but I remember feeling like I was supposed to go inside. I didn't. I just stood there for a while, looking at the door. Then I was back inside, and the dream shifted again. I was somewhere else, still holding the umbrella, but I don't remember where. I woke up before I figured out what I was supposed to do with it."
