A lightning storm over Wisconsin has sent Stranger Things fans wild after it appeared to look exactly like a real-life version of the hit show’s ‘Upside Down’ world. Video footage captured by Kasey Gelhausen shows the dark red sky lit up by flashes of sideways lightning. In scenes reminiscent of the Mind Flayer’s appearances in seasons one and two, the spooky skyline has captured the imagination of fans online. One said: “Just waiting for the Mind Flayer to appear.” Another added: “This is Hawkins Indiana and there’s a mind flayer acoming.”
