small broom

I dreamt that I was in a large room. I forget a huge portion of the beginning of this dream. There was a girl there I grew up with (SM). It was as if we were prepping for an event. The room was a large cube. Probably two story high ceilings or more. There was a large rectangular part of the floor that was taken out, large enough to fit a couple of cars in. There was broke up branches and log all over one part of the floor. We were supposed to be dressed a certain way and there were a pile of costumes at the opening of one side of the building. I had one shoe and couldn't find the other. I found a small broom and tried to start cleaning up the wood bits.  Then SM came with a larger more efficient one. I felt threatened, missing one shoe, wanting to be of help but feeling like even if I had an idea, it would be taken, if I tried, someone had better tools. I kept sweeping.
