It started as a nightmare. Comics writer Adam Ellis dreamt of a strange boy with a grotesquely crushed head, and a warning: call the boy "Dear David" and ask him two questions, and he'll answer. But ask a third, and you seal your fate. But he didn't heed that warning. And ever since, his rocking chair has rocked all on its own, objects around his apartment have seemingly been moved by unseen hands, and every midnight on the dot, his cats become obsessed with...something on the other side of his door. He's been telling the story, complete with photos and videos, on his Twitter page for the past couple of months.
Now, we're not going to try to argue about if "Dear David" is real or fake. But we know for sure that it has blown up the internet. But why? Why do human beings like ghost stories so much? Even if — sometimes especially if — we don't believe them? In other words, why do we like scaring ourselves so much?
