Though I've never personally experienced what you are describing, you are farther along the road on this project than am I. Based on what you are telling me, and if it were me that it was happening to, what I would do would be create a dream character to back you up and then go in and confront 'it'. It might be a bit easier if you have a friend to back you up, so that's why I recommend you create a DC as backup. Along those lines, it becomes easier if you call it out and it therefore becomes a visible enemy. You could read more into creating DCs in Talon's CALD topic on ld4all (link in my signature).
