Facts About Stranger Things
The title was loosely based on Stephen King novels
When the show wasn’t going to be set in Montauk anymore, the Duffers needed a new title so went and bought an old copy of Stephen King’s novel Firestarter. They used the cover of the book to come up with different ideas and eventually settled on Stranger Things.
This was partly because another King novel was titled Needful Things and they liked the to-the-point nature of the title. However, it took them a while to definitely settle on the name.
