I've already nearly lost myself once before. [Tilting his head towards the trees, where the dream shifts around to open the trees up towards the hide-out the rebels on Seheron were hiding in, after they killed the kids in the orphanage and their Tamassaran]
[And there's someone there who looks distinctly like Bull, watching the other qunari in front of him fall and the moment where this dream Bull loses all sense of himself and starts slaughtering them all -- and Bull in the middle of a fight isn't totally unexpected, although this fight lacks Bull's usual finesse and enjoyment of the fight itself. Instead he just looks desperate and cornered, hardly responding to anything beyond a need to kill everything in front of him, indiscriminate in killing everything. Also very unlike Bull, when there's a last enemy, Bull seems to waver, lets his guard down, as if expecting the tal-vashoth to just kill him and get it over with -- only for him to maybe change his mind at the last moment and behead the rebel, instead]
[Bull's not necessarily meaning to show this all to Dorian, since in general he speaks so little about Seheron, but Dorian's also the only one who'd likely get to see this particular dream in as much detail as he can]
