One thing the dream sequence person says that got my attention is "agony suits you, suffering less so" and considering the presence of Loviatar it got me thinking, suffering being the domain of both her and Jergal, who is referenced lots as well.
Another thing is that Swen, during the podcast where he mentions the dream NPC, refers to the custom character (player character) as "avatar" briefly, correcting himself right away. Although english is not his first language it didn't escape notice as that is something in the realm of possibilities, either for the player or the dream sequence. Just throwing thoughts here.
