I'm noticing that after the dream, you can talk to Astarion and win his persuasion check to get +approval. After that, every option I tried resulted in a huge negative approval hit to Astarion except speaking to Lae'zel and then Astarion, then leaving camp. I just spent 45 minutes reloading and trying every possibility and they all end up in a very large approval hit that would not appear in dialogue, but at least a minute after you walk away.
