Hello. When he is like that,he tells me,he is 'sorting things out' ,kind of undoing the web of connections and associations that ocd has created.he is trying so hard not to use his ocd that it kind of become his ocd subject. He gets 'involved' with something he thought or an intrusive image and it can spiral out of his control to such an extent that he is motionless,rigid,stares at one spot ir blinks rapidly. U can see that he's not in reality. When he finally comes out of it,you can see it in his eyes that he is back.he is trying to say something to himself as a reassurance and help himself but ocd is blocking his internal monologue.it is a power struggle. OCD vs HIM. It's scary.
