When you can recognize that the other person is attributing thoughts and feelings to you that aren't what you are thinking and feeling, and so you realize what it happening is about them and not about you.. it helps. Then you say out loud that you don' t feel what the person is projecting onto you. (You know inside it is what the other person is feeling, since it is projection).

So you don't have to take it in, you can let it bounce off and fall away because it isn't true. We each know our own truths.
