Hello Aphrodite. I feel that the house symbolizes your Mind or psyche - it is open and accessible (no doors, move freely about), complex (many rooms), and coloured with awareness (white decor). Yet there is something you are fearful of and avoiding.
So, questions ...
Is there a Leo in your life that you are keeping at a distance?
Are there issues with an authority figure, or your father?
Is there some overbearing or overpowering situation in your life that you wish to avoid?
Do you need to exert more power in some situation, but do not want to?
These are some possibilities, and there are others. Anything sound familiar yet?
