I have the Wyll windmill glitch, but was able to progress to the Spike confrontation and get his later camp dialogue. It is a new glitch.
I've always had Astarion not give me a chance to inquire about his dream when I talk to him after my fav companions. If you talked to him first though then it's a new glitch.
Yes, I was just about to update this thread to see that I figured this out! It seems that only the companion you talk to first gives you detailed commentary on their dream. All the others get cut off after one phrase. I usually talk to Astarion first, but this time I talked to Lae'Zel and she said

I don't think it's part of the game by design, and hope that we will get to hear *everyone* explain their dream in full after final release.
