Dreams that you are a celebrity means your desires and wishes may be beyond your reach at the present moment.
To dream that a friend or lover becomes a celebrity suggests your fear of losing the friendship and loyalty of this person.
To see a celebrity in your dream, or even to be dating or making out with a famous celebrity in your dream, represents your understanding about him or her and the feelings he/she generates in you.
Something in your waking life has triggered these similar beliefs and feelings.
If you dream about being friends with a celebrity, your dream is telling you that you should have higher self-esteem. You are worth believing in. You need to work on believing that you are a special person.
It is not uncommon that a real-life obsession with a certain celebrity may carry over onto your dream world. Celebrities are often seen as heroes and role models for certain qualities or the fame and acceptance we want to achieve ourselves.
To dream about a celebrity dying signifies that your feelings about that person are changing significantly. Perhaps you no longer admire what they once represented to you.
Alternatively, you may want to repress that aspect of yourself that is represented by that celebrity.
