Your house would represent some aspect of your life. Unique characteristics of houses or buildings that stand out are key to interpreting in the correct context. Different rooms also have special meaning. What if you are in someone else's house? Perhaps your dream is regarding your position within a group or in someone else's life. Dreaming of your parent's house or the house you grew up in could indicate issues of the past.
Finding hidden rooms, or rooms that you were unaware of in your present house can indicate a new potential for your life that you are just now realizing.
Expanded house dream:
I dreamed that I was looking through our house and realized that there were many more rooms available that we weren't even using! I told my husband that we could take all of the furniture that is in our garage, clean it up, and put it on display in one of these rooms--for people to come and browse and borrow. I was so excited as I looked and saw new empty bedrooms and office rooms. Lots and lots of them. They were very clean and ready to move in. Part of the house was also connected to Bank of America. Then, I went into a basement and there was this huge garage--very clean, no junk, with a beautiful, wrought-iron garage door, very fine quality. I wanted to bring my car down and use the garage!
Interpretation:
Your dream says that you are realizing that some major life expansion that has taken place, paving the way for the abilities and gifts you have stored up to be presented and offered to others. You are becoming aware of the vast potential opening up for new relationships, work ideas, networking, and abundant financial provision. There is also the opportunity for a fresh start, a clean slate with no clutter or 'baggage' to hinder you from a safe haven of operation.
