I think you get what I was fumbling around to say. I also think all of the possibilities for hallucinations you mention are plausible.

I used to dabble in some of the theories your husband has raised. I understand why he would go there. However, in my experience going down those paths further loosened my grip on reality like you mentioned. I'm not saying he's wrong, I'm just suggesting I've gone down both paths and that one is much less preferable to me at least. To each his own for sure. This is all such an individual and unique experience

There was a doctor who heard voices. She started working with them as though they were messages from her subconscious. It helped her to address them and get rid of them. I'll have to try and remember her name.

Making the man go away is of the utmost importance. I agree completely. My mind is analytical and I'm used to tackling problems a certain way. It is my style to first break it down and look for patterns and a possible root cause. So in this case you may be less concerned with why the man appears, but in my mind knowing why he appears is potentially key we need to solve for how to make him go away.

Otherwise, you're just treating symptoms hoping it works. This seems to be why meds are only partially effective. We do not understand the root cause of various mental issues and therefore we have yet to develop effective strategies to fully solve it.

Thanks for explaining how he's not really watching and more of an uncomfortable unwelcome presence. That is different. You're a sport for considering all of these possibilities. I always like talking with you!
