The story of "Dear David"

In August 2017, writer and cartoonist Adam Ellis posted a series of tweets in which he detailed a possible haunting in his apartment, centered around vivid dreams in which a dead child named "Dear David" would torment him.  He could ask David two questions, but was told to NEVER ask a third...  the tweets became a viral sensation, with the creepy experiences snowballing into a series of bizarre events, backed up with photo, audio and video evidence.  The Twitterverse exploded with theories and debate with eagle-eyed followers using technology to notice small hidden details and go even deeper into the rabbit hole.  So, was this an authentic haunting, or just a really good ghost story told in a clever way?  We deep-dive into one of the biggest pieces of internet horror lore like only Disquietude can.
