I seem to be stumped on both. To avoid spoilers, I'll just refer to where I'm stuck at by the Journal ID (just look the quests up on the Gamepedia wiki to see which stages the IDs refer to).
Dream and Memory is at Journal ID 20004 while The Trials of Durance is at Journal ID 10003.
All I can find about both is just resting (specifically out in the wilds, not at an inn) but I've been at both of these stages for a good chunk of Act 2 and all of The White March Part 1. Durance in particular has been in the party the entire time.
Now, two of the things I can ask him about (Magran and the region) are still highlighted like there's other things for him to say, but I've been through both topics top to bottom and can't find anything that I haven't already asked him.
With the notable lack of progress I've been having, I'm worried that I won't finish either quest before the end of the game. This is the first time I'll actually be finishing the game and I intend for this to be the playthrough I import into Deadfire so I want to try and finish everything I can.
