Christine – I see this as a dream about your future growth - the growth of your personality or potential.
It starts with you in a store, which often relates to you looking for something you are seeking or want. And then a woman stands on your left – if you are right handed this suggests your less dominant self, the self that stands in the background of your behaviour but is not expressed so prominently. The woman with black hair, skin and clothes also suggests a partly unconscious self – in the background again.
So I feel the last thing that was said, "There are two planets in this house and one of them has to leave” seems vital. A planet is a world, and a world in the language of dreams is a different life and culture, so I feel that the mention of you mother ties in with the different hats – thoughts and style of presenting oneself – and the dry cleaning suggesting a change that is still about your potential.
The two worlds could therefore be about the world you grew up in from the influence of your mother, and the ‘you’ that has been kept in the background that you are emerging into or growing towards.
There is an awful lot of growing going on.
