You can either dream that someone is judging you/disapproving of you or that you are judging/disapproving of someone else. In either case, a judgment indicates that you judge yourself in that same way. We generally only see the “imperfections” in others that we don’t like in ourselves. So rather than focusing on what you don’t like about someone else, examine the judgment and figure out why you don’t like that particular quality. Examine how you feel about yourself in regards to that quality.
