Basic meaning: People usually represent various aspects of yourself, albeit in many cases unconscious: wishes, fears, drives, habits, attitudes, and so on.

(1) If some celebrity or public figure appears in a dream, the person may be there to express something about you or someone close to you.

(2) A famous person may represent what you would like to be. This may correspond to your shadow-self, the other side of your personality that is still buried in your unconscious. If so, it means you should incorporate into your conscious life those desired qualities that you see in the famous person, because they are already present - latent - in you.

(3) Alternately, what the famous person represents may be a part of your personality or behaviour patterns that you have refused to acknowledge - for example, aggressiveness or a will to dominate.

Seeing people you know in your dream means qualities and feelings of those people that you desire for yourself. Seeing people you don't know in your dream indicates hidden aspects of yourself that you need to confront. Seeing people from your past in your dream, refers to your shadow and other unacknowledged aspects of yourself. It can represent a waking situation that is bringing out similar feelings as your past relationships.
