Fans of Stranger Things have always been curious about the existence of the Upside Down, mainly its Hawkins counterpart. Does the Upside Down version of the human dimension only exist in Hawkins or does it extend to other parts of the world? Whether there is another Upside Down elsewhere, the question on most people’s minds is how it was created in the first place. Some fans suggest it has something to do with a young Will Byers (Noah Schnapp) and his disappearance in 1983.
