Director Wes Craven was inspired to make this film from a story he read in which a young boy was terrified to go to sleep. The boy's family reported that he had nightmares of being killed in his sleep. One night, they heard screams coming from his room. When they rushed to his bed, they found that he had tragically died in his sleep. Craven personified this story with Freddy Krueger, and the rest is history.
