The Dreamers by Karen Thompson Walker

A college town is suddenly in the middle of a plague which literally makes people lay down wherever they are and go to sleep. Ground zero looks to be one of the college dorms but soon the whole town is affected and infected. Students, families, faculty, the elderly and the young - all will be touched and their lives affected. This is a subtle coming-of-age, horror, love story with a moral message about the haves and have-nots. The characters are meaningful and normal enough that we identify with them but their situation is so horrific you can't help but ask yourself what you would do in their place. Who would you save and what lengths you would go to keep your family safe. COMA meets THE ROAD, this is one thriller you should not miss but you will miss sleep.
