Something that's always confused me is kissing bodies. Does this just wake up the dream self, forcing them to find a way off the moon, or does the dream self take over the body while being in the same place? It seemed that it was the former with Jane, but I'm not sure

It wakes up the Dream Self, whether they’ve been knocked out, are simply asleep, or have not yet awakened in their Moons, corpsesmooching is a surefire way to get Dreamers to wake up if they haven’t already, and take over for the now deceased body.
