As far as we can look back into our past, humanity has both interacted with and been haunted by the spirits of the dead. The tales of apparitions and hauntings pervade not only our most popular art but also our psyche; seemingly everyone has a ghost story to tell. While modern skepticism waves away ghosts as being merely the product of fear and imagination, many these days are saying that it is not so simple. Ghosts still have much to tell us, if we allow ourselves to be willingly haunted by the ideas that they bring forth.
