And I'm not presenting my statements as "proof". I don't know whether they die permanently or not and I suppose it could go either way. I am not trying to prove anything myself. I am pointing out the flaws in your proofs. Your evidence is relying on unreliable statements (no concrete evidence) from people who don't know anything about human souls. Just because Birgitte knows MORE doesn't mean she's either correct or accurate. I've read statements of a lot of knowledgeable people in scientific or clinical fields that are STUPID wrong. Even if she is correct, her soul is presently different than a human soul. When she does, it goes to T'A'R'. When a human soul dies, it goes elsewhere. If you kill Birgitte's soul in T'A'R', it has no where to go, it's already dead in its destination.

As an additional thought, there's the everyday risk that your nightmare will enter into T'A'R' and if you die you're dead. This is something that affects neither dreamers, nor wolfbrothers, nor Heroes. it's possible that these unlucky people are just "Dead", but given the general patterns throughout the cosmology of Randland, I doubt this. They probably just die and their souls go wherever human souls go. However, they would be being killed in T'A'R' just like any Dreamer. Jordan does not strike me as being the sort of author who would prescribe this fate for his peasantry and non-heroic innocents.
