About the title
18-year-old Sarah has run away from home and now sleeps outdoors on a playground. Every night she has strange, frightening dreams, so when the girl sees an ad from a sleep study institute looking for volunteers, she jumps at the opportunity. The test subjects' bodies are covered with sensors, and after the first night Sarah feels well-rested, but when the researchers show her vaguely familiar black-and-white images, the girl has a seizure.
