I do relate to what you describe. My T has told me that experiences me as even psychotic sometimes. It does not mean that I really do have psychosis because soon after I leave my session, things look in a different light again. But yes, it certainly feels like a completely different state of mind.

And what I've found characteristic to it is that it does not seem to contain any memory nor is it susceptible to learning. Although experiencing this state definitely gives information about me to reflect on after, experiencing it repeatedly does not seem to alter this state itself very much. It's like a state without any memory about that it has happened before or what I have been thinking about it meanwhile.
