Dream fall

"Seven teenagers who suffer from debilitating insomnia agree to take part in an experimental new procedure to cure it because they think it can't get any worse. But they couldn't be more wrong. When the lab equipment malfunctions, the patients are plunged into a terrifying dreamworld where their worst nightmares have come to life-and they have no memory of how they got there. Hunted by monsters from their darkest imaginations and tormented by secrets they'd rather keep buried, these seven strangers will be forced to band together to face their biggest fears. And if they can't find a way to defeat their dreams, they will never wake up."--Amazon.
