This is an illustration of a dream Jonas, the main character, had had the night before. It is a family ritual to share your dreams, and you must share it all. This was when he began taking pills to stop the dreams. My guess is they regulate your hormones so teenagers don't breed with non-birthmothers. His mother keeps him home after she hears the dream and introduces the pill to Jonas. He felt pride when he was able to take them like others in his age group and is now more mature.
