A symbol of creativity, of the ability to create your own world the way you want it.
If you dream of a famous artist, you need to ask yourself what this particular artist means to you, and how you feel about his or her work.
If you’re a fan, then you’re on the right track, either with regard to a specific matter you’re concerned about or your life in general.
If the artist is an unknown male figure, then your intellect is trying to convey a message about something you’re working on. Consider the picture: Is it just begun, half finished, nearly complete? Is it a good painting, or is it a mess? If the artist is an unknown female figure, then the picture concerns matters of the emotions.
Again, look at the picture itself, as well as the other symbols in the dream, to judge what the picture is trying to tell you.
The same goes if YOU are the artist.
