I want to have a session where my players drift into a sort of dreamland where I can introduce the BBEG and some other story points in a way that doesn't actually affect them. So they go to sleep, "wake up," go on this quest type thing to face the BBEG, they get to feel the utter difference in power level compared to them, probably end up dying, but as they die they wake up from the dream realizing it's a "vision of the future" type thing.
I think it's an interesting, cool idea, but I realized that one of the members of my group is in fact a skeleton PC. Technically, the undead don't sleep and so now I have no way to include him.
I've wracked my brain, but I can't think of a clever solution that fits to allow him to participate in the dream/vision thing. Any suggestions?
