Your ability to shine and perform or to receive recognition and applause for a job well done. What the celebrity is doing in the dream may reflect how you are acting in life or in a particular situation.
The best way to figure out what the particular celebrity in your dream means is to ask yourself what he or she is best known for, what qualities do you associate with that celebrity. Perhaps it is a song they sing or a role they have play. What song of theirs stands out to you? Does the title or the lyrics hold a message for your life right now?
Perhaps it is a role they have played on TV or in a movie. What is that character like? Do you recognize yourself in that character? What else stands out about that celebrity? If you applied those qualities to yourself would you shine in life?
