Activities that purposely allow yourself to be used or taken advantage of, that sell yourself short, or that allow others to cross your boundaries can represent feelings that you must do something like this in real life for some reason. Consider what's behind these feelings (beliefs, judgments, lack of support for self, or other issues). Dreaming of someone else doing this could represent a perception or judgment you have of that actual person (or whoever or whatever they represent), or the way you are labeling that person in your mind (for example, you might think they are self-sabotaging or insecure).
