Ready to head back to the Upside Down? Stranger Things' Season 4 has been confirmed by Netflix, who has been gracing fans with short but sweet teasers letting everyone know that it's in the works. While we already knew it was coming, seeing everything happening like this in an official capacity is still exciting. But the announcement came with one interesting clue that we're still unpacking. It's the following message: "We're not in Hawkins anymore."Netflix's first teaser for Season 4 is super brief, but it takes viewers to the Upside Down for just a moment after showing us a quick view of the "Welcome to Hawkins" sign and a new logo that appears to be covered in creepy vines of some sort. In the background, we hear Westminster Chimes, which could be a nod to Big Ben in the U.K. — while not likely to be the setting for next season, that is where Millie Bobby Brown (Eleven) is from IRL, after all.When does Stranger Things 4 start filming?It's been more than two years since Netflix confirmed that there would be a fourth season for Stranger Things. It's safe to assume filming is underway for the new season, given the teasers that have been shared.On May 5, 2020, the channel posted a video titled "HNL Control Room." The video shows various security camera screens, each flickering to reveal a blood-splattered scene for a couple of seconds before returning to static.\n\n"Due to technical difficulties, Hawkins National Laboratory will be closed until further notice. We will be back in service tomorrow at 9:00 a.m. ET," the video description reads.The following morning at 9 a.m. EST, the channel posted another video, this one titled "Eleven, are you listening?" \n\nThe video appears to show various shots from the laboratory where Eleven was kept at the very beginning of Season 1, and Dr. Martin Brenner, or "Papa" as Eleven called him, makes a brief appearance. This video's description reads "002/004," implying there will be two more videos to come.When can we watch 'Stranger Things' Season 4?We haven't gotten all four of Netflix's teasers that are expected to come just yet, but the strange and unsettling ones we do have suggest it'll be a season worth the wait.The latest look was released on Aug. 6, and confirmed that viewers won't have answers to their myriad of questions until 2022. There's no official release date just yet, so it looks as though we'll have to wait a while longer for the new content.Here are some 'Stranger Things' Season 4 predictions:While we don't quite know just yet what will unfold during the upcoming season, it's never too early for spoilers. There's one important bit of information we know about Season 4 that we can ascertain from the ending of Season 3.The show ended as Will Byers' family packed up their belongings and set off for a new home outside of Hawkins, Ind. With Eleven in tow, the Byers family was looking for a fresh start following the supposed death of Hopper.With nothing left to keep the family in Hawkins beyond the rest of the Hawkins gang, Joyce Byers thought it best to move away from the massively dangerous town in a bid to keep Eleven safe.Though it appeared that Hopper sacrificed himself in a dangerous burst of energy that he couldn't possibly have escaped from, a post-series scene where a Russian captive is referred to as "the American" had viewers guessing. It was later confirmed that David Harbour (who plays Hopper) would be returning for the new season.Our guess is that the show will shift to big-city living for at least one of the families, and we'll see Eleven struggle with some sort of coming-of-age story before she finally comes into her own.The only thing that's certain now? We need to see the next season, STAT! The wait is officially on, and we're already having trouble counting down the days before we're reunited with our favorite kids from Hawkins.
