I had a dream

I had a dream where I was trying to escape from some people (who knows why) and we were in a building where the furniture was packed close together (pretty much no open space), making it an obstacle to get around. But not only that, but if you were on a lower level, the floors would seem invisible (but not the furniture), so you could sort of see the people on the above floors (and in my case, see how close they were to catching you, so you could move away from them). The building was a combination of many different homes and apartment buildings I've lived in throughout my life.
