' Horror ' stories of fairies

One popular belief was that they were the dead, or some subclass of the dead. The Irish banshee (Irish Gaelic bean sí or Scottish Gaelic bean shìth, which both mean "fairy woman") is sometimes described as a ghost. The northern English Cauld Lad of Hylton, though described as a murdered boy, is also described as a household sprite like a brownie, much of the time a Barghest or Elf. One tale recounted a man caught by the fairies, who found that whenever he looked steadily at one, the fairy was a dead neighbor of his. This was among the most common views expressed by those who believed in fairies, although many of the informants would express the view with some doubts.

ooh wow! thats amazing!!!

Demons
A fourth belief was the fairies were devils entirely. This belief became much more popular with the growth of Puritanism. The hobgoblin, once a friendly household spirit, became a wicked goblin. Dealing with fairies was in some cases considered a form of witchcraft and punished as such in this era. Disassociating himself from such evils may be why Oberon, in A Midsummer Night's Dream, carefully observed that neither he nor his court feared the church bells.

The belief in their angelic nature was less common than that they were the dead, but still found popularity, especially in Theosophist circles. Informants who described their nature sometimes held aspects of both the third and the fourth view, or observed that the matter was disputed.
