Director Craven revealed that the inspiration for the iconic slasher film came from a story he read from the LA Times: a boy was having disturbing nightmares and refused to sleep for days out of fear. The same night he succumbed to exhaustion, he died in his sleep, but not before screaming for help in the middle of the night because of his nightmares. Apparently, parents don’t have to freak out if their children can hear voices. Around 8% of children do, which is as common as having asthma or dyslexia. Hearing voices is definitely creepy, but at least it’s perfectly normal.
