The out of body thing for me was times when "I" was not behind my eyelids. At times I could feel my feet, my hips, my buttocks but maybe not my hands, elbows, shoulders, spine or back of my head when supine or sitting. Other times I could have all or most all connections and still at others none. I have discussed this before various times in several years here... basically "I" was outside my body just in front of the bridge of my nose (usually) when frightened or in pain I would go farther and see myself either from in front, behind, to the side or above from the ceiling of a room.
Body sensations were muted, and there was little to no pain awareness until on some subconscious level I deemed it safe and I came back in or back in half way. I lived like that for probably many years. The downside was being accident prone as the therapist described "me" as a mind dragging their body around which led to various minor injuries, bumps and scrapes, cuts or burns, etc.
I get cues now when I'm "out" and learned how to put myself back in, but still sometimes, particularly in the retelling of traumas I go out or halfway out... so I had to keep telling and practicing and learn how to pick up on the cues, put myself back in, resume in telling trying to manage the body reactions or decide to stop the discussion depending on my state.
