In the horror film before I wake are the nightmares of a boy real, by manifesting his gloomy dream figures in reality to real threats.
In before I wake decides the young couple Jessie and mark to do so, the orphaned orphan boy Cody to adopt, to finally found a real family. The 8 year old is a loving and good child, which however has apparently for fear before, to go to sleep. Initially, his new parents still assume that his reluctance to lay in bed the rest stems from bad experiences from previous foster families, but soon it will be disabused.
In truth Cody’s fear stems from that, that his dreams – in particular his nightmares – become a reality, while he sleeps. Everything the boy dreams, takes physical shape and because the orphan has a vivid imagination, Jessie and mark through his manifest fear of night fall soon in great danger.
