According to Jung, your life specifics are very important in making good interpretations. Age, sex, marital status, career, birth order, etc.

In general, though, the house would represent your psyche. The rooms of the house are different parts of that psyche.

Females in dreams most often represent your animus, or feminine characteristics. Perhaps the dream is telling you to honor your animus- the bathing or anointing of the old woman's feet. By accepting your animus and actualizing it in reality, you will morph into the real man that you are capable of being.
