I use to dream about an apartment building I lived in for 13 years. My T and I agreed the recurring theme implied I was struggling/working with things that had happened during the time I lived in that place.

Were yours my dreams, I would look at the period I lived with my parents and issues from those days and/or with those people. The parent/child triad in dreams is often important as anything three-legged like that is very sturdy. The dreams could be about your whole "support structure" as it were.
