dream

In my dream last night, I was swimming in a large, public swimming pool that had no windows.  I also realized that I was swimming with my white cheese muck boots on, and that they were filled with water so very hard to swim with.  I also thought that because I was in a pool, it will clean the boots off, but when I looked down they still looked dirty.

A young man at the edge of the pool threw an empty Pop Tart box into the water - chocolate frosted flavor - and I swam over and tried to kick the box out of the water, but my boots were so heavy I couldn't do it.

Doctor, what does this mean?
