If you dream of your old address, or dream seeing your former house, it means you have an unresolved issue with your old place.
You may have loved staying in your old home. Or you have bitter sweet memories of your former home. Maybe you think the house was good for you. You may miss your old neighborhood, or your old friends in that neighborhood.
You can interpret your dream, by reflecting on your context. Then its up to your decision, on how you would proceed to deal with this issue. Like, are you returning to your old neighborhood for a visit?
