So, I just had a thought and was wondering if anyone can kinda clear up this confusion in my head.
Solas has been sleeping for round about 1000 years right? And he makes the comment about waking up and seeing things worse than what they were.
But, he talks about dreaming at Ostagar and seeing current events.
*snip*
We don't know how long he has been awake, but Corypheus has been working on his plans for at least a couple of years, I think. And Solas has been traveling as Solas and trying to do things like communicate with the Dalish for at least a little while. So it's not possible to pinpoint when or what woke him up just yet.
Though there is a ton of speculation.
But yes, in uthenera, a person's mind is just in the Fade, so things are jumbled and interpreted and all that, as the Ostagar stuff shows. It's also a good reason why Solas and Varric's banter includes many presumptions about the dwarves and Varric speaking optimistically, while Solas is more preoccupied with the downfall of a great people. He didn't know any of that. Also, with dwarves, things are funny since they can mine lyrium with precautions and are supposedly cut off from the Fade and magic. Red lyrium being an obvious exception.
But if they're cut off from dreamd and thus, The Fade, this also explains why Solas was unable to see or understand what happened to them and thus, he sees the negative.
And even after waking up and returning to the world, everything is awful, according to his perception. And he blames himself for whatever it was that he did (of which we know only the barest detail). So he spends a lot of time dreaming in the Fade, even after waking after spending all that time in Fade stasis. It IS sad. He's a character with so many layers and so much pain.
Once you realize all his time in the Fade now isn't exactly all about making new discoveries, as he's selling it to you. The Fade is where whatever remains of the world he knew, his life, hopes, dreams, cities, people (aside from Mythal, at least).
Wait, wait. Guys. You're forgetting that the Fade has a completely different time mechanic. We've seen time and time again some kind of spirit "recreation" of events, especially where the Veil is thin, that span a very long time in Thedas terms, or short ones, too, yet for the spirits of the Fade no time has "passed" at all. We've even seen spirits trapped in a kind of loop until someone or something releases them. I.e. whether Solas dreams himself into the Fade or if his consciousness was floating around there, or even if he was physically there at whatever point, the distance in time doesn't matter. For all we know, the events of Ostagar could be playing out over and over for centuries to come and I wouldn't be surprised if the Veil thinned considerably after such a battle, after so many intense and tragic emotions flooded that place, so Solas could easily have wandered the Fade to pick up information a couple of weeks or days before the events of Inquisition and base his knowledge about recent events on what he sees there and it would amount to the same thing (unlikely, as I concur that he obviously attempted to make contact with the Dalish and his tone seems to imply that this happened "a while ago" and several times). He's obviously spent enough time awake to at least get a grasp of the major events in Thedas, yet all the information he gives us is tantamount to the same rumors no doubt we heard, so it really doesn't indicate anything at all about when and how he woke.
I agree about the dwarves, though, that regardless of how long Solas has been awake, he must have some "recent" memories of dwarves being different, powerful and in control, even if they were cut off from the Fade at the time (he implies the downfall, which would imply that he saw them pre-Blight, yet there isn't a lot of indication as to when the dwarves changed, if that's what happened - correct me if I'm wrong). His opinions about dwarves seems similar to his opinions about the Dalish to me, he has drawn his conclusions, so to speak, without necessarily seeing the whole picture (and that to my mind suggests that he can't have been awake for too long, because his beliefs haven't had time to adjust to possible new, expanded experiences of the races).
I'm not saying this to be contradictory, I'm merely saying that we should speculate on these with that in mind, i.e. that Thedas chronology is absolutely no guide in this question for the above stated reasons.
