Are you ready to travel back to the Upside Down?!
Stranger Things Season 4 teaser trailer just dropped giving us a quick look at Eleven's fellow test subjects in the next season of the show. The scene is a flashback of her time in captivity as Dr. Martin Brenner greets a bunch of children.
There is no release date for Season 4 just yet, but I hope it's soon!
Check out the trailer below
