I think it could be said that dissociated parts of ourselves are like ghosts trying to get our attention. It is like they are trapped on the other side of a door, but they can pound on the door, whistle, and otherwise make noise. This is what creates outwardly irrational behavior. It is perhaps like they briefly take control of our bodies and make us do and say things we otherwise would not have.
The ONLY way to deal with this is to establish contact with them, through deep silence, and by making the effort to open communications. I think most people have aspects like this, although it may be limited to trauma endurers.
I just made contact with some part of myself which got over the fence, and is back in-house. It is like an old and wanted family member.
This all sounds crazy, but the fact is most of us ARE crazy but don’t know it, and the only way to go from being crazy while pretending to be sane is to pretend to be crazy while being sane. I believe I am well justified in my view that my reality testing is significantly better than most.
