Maybe your dream is waiting for you to let him go. If you are aware that you are dreaming, try to make a conscious effort not to curse him out, but to let him go. Wave when he waves and tell him, “Good-bye”. (Kinda like the preacher that kept preaching the same sermon each Sunday. When his parrishioners compained that he needed a to preach a new sermon, he said, “Well, seems like you haven’t heard the first one yet.”).
