I also experience so much of this sense of things being surreal or like we're looking in on a pre-recorded movie clip that we can't interact with directly. And when we do we feel surprised to see our bodies entering the scene.

I briefly discussed a fit I had with my first psychiatrist, and he thought it was probably a kind of seizure, but I have kept the derealisation experiences from all pdocs. Partly because I'm tired of being hurt by them fobbing me off on other matters I am concerned about, and I certainly don't want to risk them sending me off to a locked ward or putting me on antipsychotics (big phobias of mine). I'd rather just live with my weird experiences and keep them to myself.
