dreaming with buildings

For some reason a large number of my dreams involve office buildings or high-rise apartment structures or large unidentifiable type downtown City buildings. In other words it might be just sort of a general convention type building or some other multipurpose building or something. And I'm moving around in the building and like a lot of dreams it's discontinuous meaning you're in one part of the building and then the next thing you know you're out in front of the building or you're in some other building or you're walking down the street in front of a different building but there's always buildings. So it's not really clear what any of that is about because I've never lived in a downtown City environment, although I've lived in the suburbs of a city for most of my life. I haven't had any particularly positive or negative experiences in any of these kinds of buildings and pretty much the same in my dreams too.
