If you weren't chronically online on Twitter in 2017, allow me to acquaint you with the thread that changed the site forever.

Created by BuzzFeed writer Adam Ellis, Dear David was a Twitter thread documenting Ellis' supernatural encounters with the ghost of a young boy. The ghost, named David, would haunt Ellis at night and had a habit of answering questions only if prefaced with a "Dear David" first — but be warned, one must only ask David two questions or else… The thread quickly became a viral hit and garnered Ellis over a million followers on Twitter. Read it at your own risk.

Six years later, the Dear David Twitter thread is now a horror film starring Augustus Prew as Ellis, and the trailer is terrifying. Taking it up a notch, David not only appears in ghost form, but as a Twitter troll mocking Ellis online with a tragic backstory and some other ghost friends. It's a full Internet-infused ghost haunting, and dare I say, is the most realistic horror film adapted from a true story I've ever seen. Don't fuck with David y'all.

Dear David releases in theaters, on demand, and on digital October 13.
