Things will “only get stranger” for the residents of Hawkins, Indiana, according to a sneak peek of Netflix’s Stranger Things season two.

Netflix announced Tuesday that the hit series will be returning on October 27. A short preview released on Twitter hinted at an ominous next season.

“Some doors can’t be closed,” read the tweet, possibly hinting at the door to “the upside down,” where last season Will Byers was held captive by a terrifying “demogorgon.”

The series announced at this year’s Super Bowl that it would be coming back with a second season. 

Stranger Things was nominated for two Golden Globe awards this year, and took home the MTV Award for Show of the Year.

The success of the show has sparked the careers of its young cast members.

Millie Bobby Brown won the MTV Award for Best Actor in a Show for her performance as Eleven. Vancouver-born Finn Wolfhard, who plays Mike Wheeler, stars in the upcoming remake of Stephen King’s horror classic It. And Charlie Heaton, who plays outcast Jonathan Byers, recently starred in the Sundance drama As You Are.
