8 Upside Down Mysteries Stranger Things Season 5 Must Solve

Stranger Things is preparing for its fifth and final season, but there are still a couple of mysteries, mostly about the Upside Down, that season 5 needs to solve. The more Stranger Things evolves, the more mysteries pop up about Hawkins, the experiments at Hawkins Lab, and the Upside Down and the monsters living in it, and while season 4 answered some of the series’ biggest questions, there are still many more that need to be solved before the audience has to say goodbye to Hawkins and all its residents – and the most intriguing and important questions are all about the Upside Down.
