Thanks to Naju who suggested me to get my dream analyzed.. :)
And this was the answer I got from one of the websites that offered dream interpretations.
An angel or spirit guide can represent the idea of receiving guidance, support, comfort, etc., or that you would like to.
Overwhelming circumstances in real life, feelings of helplessness or hopelessness, or something feeling out of control—or a fear of such things.
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.
And honestly, I'm not satisfied yet with the answers. Might check some other sites. :)
