'Stranger Things' Trailer May Support Totally Upside Down Theory

'Stranger Things' creators the Duffer brothers weigh in.

The Season 2 trailer for “Stranger Things” premiered over the weekend to much fanfare, and the theories being generated around it may turn your world upside down.

In an interview with HuffPost, producer Shawn Levy said he and the show creators, the Duffer brothers (Ross and Matt), worked on the trailer for more than two months, securing the use of Michael Jackson’s “Thriller” only days before the clip’s release. Levy says “every shot” of it was debated over.

“We wanted to show a real taste of what’s coming, but to not give any of you guys the feeling that you’ve seen everything that’s gonna happen. So it was a matter of balancing how much we reveal, how much we withhold,” said Levy.

But was more revealed than planned? Perhaps.

First, we need to go back to a Season 2 poster that was released in the weeks leading up to the trailer. One Reddit user pointed out how the monster in the poster may not be an “actual physical creature.”

“It looks like it’s made of cloud,” said the Redditor, adding, “I’m guessing that the monster is actually in the Upside Down, but somehow the barriers between the different dimensions are breaking down, and, just like the trailer said, ‘the world is turning upside down.’”

The Reddit comment got us thinking: What if the monster isn’t an actual creature?

The theory: The monster is the Upside Down trying to take over the real world.

Up until now, we’ve just assumed the Upside Down is a place. But could it be an actual living thing?

To be honest, we were probably going to dismiss the idea if not for one peculiar scene from the Season 2 trailer.

Following a part where Chief Hopper (David Harbour) says, “Whatever is happening is spreading from this place,” there’s a voiceover from Joyce Byers (Winona Ryder). She appears to ask her son Will (Noah Schnapp), “What does it want?”

He replies, “Not me. Everyone else.”
