It seems when one dies and they become a ghost, they can still get Progression by roleplay experience.
Having died, after about 3 or so in game hours I wandered near some players and emoted how I died, I received the message tick for experience. Leaving for a bit again, and returning, and performing a similar emote, I received yet another message tick for experience.
I don't know if I am actually receiving the experience, because of the game design, but figured if the message wasn't supposed to be happening at all to post it here, since the journal entry says I'm not supposed to be able to learn anything new in this state.
