. Bodynatching is different. Nothing can inhabit your body unless they physically drone or chip you.

Bobysnatching may be different, when it is PERMANENT. But to say "Nothing can inhabit your body unless they physically drone or chip into you"- that part I'm going to have to disagree with.

Blackout while drunk- classic case of SOMETHING ELSE coming in & inhabiting your body for a short time. And this is something I have personally witnessed in people. Also there are cases of Possession.
