A house, apartment, flat, or any place of residence often represents you or your life, even if the dream residence does not resemble your actual residence. The events in the dream residence may represent events in your life. A house can also represent security, comfort, protection, familiarity, or belonging.
Also consider the mood and condition of the house (a dreary house might represent depression or sadness, a house with missing windows might represent personal boundary issues, etc.) and anything that particularly stands out about the house.
