What does it meaning yourself, in the dream?

Makeup usually symbolizes falsehood in human relations. Consequently, when the characters of our dreams groom themselves, these images are related to cheating and lying.

The same happens when you use makeup yourself. Distorting your image can prevent you, momentarily, from seeing your own shortcomings. But sooner or later the mask will disappear and your disguise will not hide the truth any longer. ... The Big Dictionary of Dreams

If you know yourself, then your life works. You do not have problems in one-to-one relationships. You do not set yourself up to be rejected or dumped on, lied to or ripped off. You do not set yourself up to be bored or frustrated, for you are in tune with and following your creative life path. Remember that no one is going to take you by the hand and lead you step by step along the way. If you want insight, ask and you will receive. But you must make your own choices and decisions. It is your life. You are the writer, producer, and director, and you are playing all the roles. Create  whatever you want. You have total freedom. It is only your thoughts that limit you. Your dream symbols help you look at the very thought patterns that are governing your life. Dreams take you to a higher level of consciousness and understanding which has the power to transform your life and your world. The whole purpose is to see objectively the life situations you are creating, survey the limitations and obstacles imposed through your own beliefs, and understand how best to work around or eliminate them. As you work on your own growth, all others will benefit; they will see your light, your knowledge and your truth.  ... Dreampedia

To fully understand the message of a dream in which a celebrity features you need to hone in on the quality they represent and decide whether it pertains to someone you know, or to some aspect of yourself. First you need to consider the outstanding trait for which that celebrity is famous, then you need to think about what makes that person stand out for you. For example if you dream of Madonna, why didn’t your dreaming mind select another female singer, for example Shirley Bassey? What is it about Madonna that inspires you? Is it her drive, her ambition, her feistiness or her ability to reinvent herself? Try to spell out in your mind the qualities this person stands for and what trait is being shown. Then consider the implications. Celebrity dreams may seem sweet or even corny, but they do have a powerful energy.

If you think the celebrity represents a quality in yourself you’d like to foster, don’t assume you have to copy them and follow their life path. Remember dreams only depict the essence of something; the way you choose to put that energy to work, and how it appears in your life, is entirely up to you.... The Element Encyclopedia
