Fans will have to wait nearly ​another year before they can ​return to Hawkins, Indiana and the world of Stranger Things. But, in the meantime, the Duffer Brothers have revealed some new secrets about what audiences can expect from the next season in their new book, Stranger Things: Worlds Turned Upside Down, which is available now.

One particularly exciting tidbit from the duo is that they promise the show's third season is going to be the "grossest" yet and will be inspired by horror legends John Carpenter and David Cronenberg. These influences point to a level of horror that might have viewers' stomachs turning.

"There are horror movies and horror masters that we haven't really paid tribute to as much in previous seasons that we are definitely going to get into this season," the Duffers say. Both Carpenter's The Thing and Cronenberg's The Fly reveled in gross body mutations and practical effects showing human bodies morphing into truly disgusting creatures. The combination of the Upside Down creatures of Stranger Things and classic '80s effects could lead to some of the hit series' most horrifying moments yet.

Stranger Things's next season will be set during the Summer of Love of 1985 and the Duffers say, "... the Hawkins pool is open for business. I think there'll be a sense of fun and joy."

However, that joy will quickly turn to terror—especially if the townspeople of Hawkins are going to suffer extreme mutations because of the malevolent Upside Down creatures.

Stranger Things's third season is expected to air in summer 2019.
