Re: SLEEPERS & DANCERS
Peter is enduring the week of being not-quite-a-ghost but beyond everyone's perception. It means wandering around and trying to pass the time around campus (and occasionally being compelled to go clean up a mess or someone's messy room), which is when he spots a few people napping on the Green. He comes closer and starts to slip...
Physically, his body on the Green is largely "invisible" to everyone, but his sleeping self can be seen by others caught in the dreamspace.
