According to Osho, whether you dream of dreaming or re-experience painful scenes, it is the same continuum of mind-dreams, night or day. Don't analyze the content; turn 180 degrees (paravritti) from the dream to the one who sees it. Emphasize witnessing. In sustained awareness, identification with the dream dissolves, the projector loses power, and suffering subsides, whether the images seem real or imagined.
Your mind is dreaming all the time; instead of fixing the dreams, simply notice the quiet watcher inside.
