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.
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.
Different rooms have special meaning. Consider the typical activity associated with each room: bedrooms usually represent rest and intimacy, kitchens are where ‘food’ is prepared, living rooms represent life, bathrooms are a place to get clean and deal with our issues. Garages are places of storage, attics store ‘memories’, basements are hidden or foundation places. Mud Rooms are places of transition.
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.
