A question about warging
So I've been gone awhile (again). I missed the discussions here but life happens. Anyway, when I last visited the Jon Snow thread was still on page 20 or so.....and in my absence it's gone all the way to 46!!! I'm only as far as around page 36 of that thread, but all the lengthy discussions about warging in that thread have left a nagging question rattling around in my skull.
When a warg enters another's body (be it human or animal), what happens to the body they leave?
Example, if "someone" wargs into a random cat in their immediate vicinity, their soul / essence / mind / whatever enters that cat but their body is still very much awake and "doing stuff".
So does the body they leave suddenly turn into some kind of brainless zombie-like creature for the duration of the warg? Or does the warg occupy both bodies to some degree?
Or for another example....
****SPOILER WARNING FOR NEWBIES****
When Bran wargs into Hodor, he's almost always "awake". So if Bran departs Bran's body and goes with Hodor off into some other location, is Bran's body just sitting somewhere in a basket staring into empty space? What if someone comes along and tries to have a conversation with him while this is going on?
