Lost

It was a normal school field trip to the science lab...right? Not for Zia. When she stumbles into a room with four others. Something happens. Now whenever they fall asleep, it's a new dimension, new places, some horrific, some amazing. But all of them have something hidden in them. And every single one of them will help them get back home. With her rag tag group, will they make it back, or are they doomed to stay on this loop?
