Netflix finally unveiled the trailer for the next season of Stranger Things at Comic-Con on Saturday, and OMG so much nostalgia.

It starts off with the gang hanging out at a video arcade. But the fun quickly turns to horror as we realize that the Upside Down isn't finished with Will Byers – and now it's coming for everyone he loves.

What else it reveals: It's Halloween, Will is dealing with nightmarish visions, the boys suit up in Ghostbusters outfits, and Eleven – who we left trapped in the Upside Down at the end of the first season – may have found a way to escape.

The teaser is especially creepy thanks to the use of Michael Jackson's Thriller, and Vincent Price's classic, hair-raising voiceover. 

Check it out:

Now we really can't wait for Halloween: Season 2 of Stranger Things premieres October 27, 2017.
