I'm no expert, of course, I'm just a guy speaking out of line on the internet, but... From what I saw from a cursory Cluster A search, this behavior is literally not even tangentially related to the criteria for Cluster A disorders. It's not paranoid, it's not schizoid, it's not schizotypal. These are lonely people who disassociate a part of their internal monologue. Please elaborate exactly, in your opinion, which Cluster A criteria these people display.
