'We are haunted during the holidays by things done and left undone, but especially by the Ghost of Christmas Past. You can hear that melancholy and nostalgia in many of our best-known Christmas songs, from Sam Smith's old-fashioned new version of "Have Yourself a Merry Little Christmas" to "I'll be Home for Christmas" to "Merry Christmas Darling." Why, in this season of joy, are we so often brought to the point of tears? Well partly it's because the past, as Mr. Faulkner said, isn't past. It's always present, swirling around us, reminding us of who we were, are, and ought to be (and maybe where we ought to be, and with whom).
Those ghosts may sadden us or frighten us, but critics who work within a literary field called Hauntology argue that in stories from The Iliad to Hamlet to The Sixth Sense, these ghosts of longing may haunt us from our past, but they simultaneously beckon us forward toward our future. A good haunting may, in fact, be just the thing we require to achieve our best destiny, to become the people we are called to become. And what better time than the holidays to face those ghosts head-on and amend our lives?' - Greg Garrett
