Spirits of the dead

One belief held that fairies were spirits of the dead. This derived from many factors common in various folklore and myths: same or similar tales of both ghosts and fairies; the Irish sídhe, origin of their term for fairies, were ancient burial mounds; deemed dangerous to eat food in Fairyland and Hades; the dead and fairies depicted as living underground. Diane Purkiss observed an equating of fairies with the untimely dead who left "unfinished lives". One tale recounted a man caught by the fairies, who found that whenever he looked steadily at a fairy, it appeared as a dead neighbor of his. This theory was among the more common traditions related, although many informants also expressed doubts.
