I'm definitely interested. It reminds me of a book I read ages ago, where the main characters were stuck in the fantasy world, except for when they slept and would act in the "real world." 

If they were asleep in both worlds, they would wake up at a weird summer camp? 

Anyway, I'm into it. 

EDIT: the book was from the Everworld series, by K.A. Applegate, but I don't remember which book, or anything else about it lol.
