Ah, thanks. In that case, I've seen something similar. Though in what I've seen, a person acts as a vessel, so to speak and the entity is summoned within them. It makes them easier to talk to the entities that way. Then someone else "pilots" the session and will be the one who will lead the interaction with the entity, though anyone in attendance can technically talk to it. The process is call Jinn catching, and is apparently controversial even among Islamic exorcists. Oh, and of course, you can call me Edge if that makes things easier.
