It's Friday the 13th, so of course the Duffer Brothers decided to release the final trailer for Stranger Things Season 2 today.

The clip begins on Halloween night in the fictional town of Hawkins, Indiana, and though Will is still safe from the Upside Down, it looks like something came back with him. He's having visions of a "shadow" descending upon the small town, and though doctors chock it up to his imagination, Chief Hopper knows better. "These are not nightmares," he says. "It's happening."

And who better to know what's going on than our beloved Eleven? Back from the Upside Down, apparently, we see her running around the woods before finally making it back to Hawkins. Though the trailer doesn't show her reuniting with Mike, Dustin, Lucas and Will, it's clear she's going to do whatever is necessary to save her friends.

Find out what terror Stranger Things Season 2 has in store when it returns to Netflix on October 27. Watch the final trailer above.
