What does it mean if you dream about gold?

it means you constantly think about money, and how to get rich.

Another answer:

The gold most likely represents whatever is most precious to you. The meaning of the dream depends on your feelings during the dream - is the gold lost? - are you afraid of losing the gold? - are you celebrating finding gold? Each of these could represent a different meaning. Yet all would have something to do with whatever is your "treasure."
