Banshee

The banshee ( /ˈbænʃiː/ BAN-shee), from the Irish bean sí ("woman of the sídhe" or "woman of the fairy mounds") is a female spirit in Irish mythology, usually seen as an omen of death and a messenger from the Otherworld.

In legend, a banshee is a fairy woman who begins to wail if someone is about to die. In Scottish Gaelic mythology she is known as the bean sìth or bean-nighe and is seen washing the blood-stained clothes or armour of those who are about to die. Alleged sightings of banshees have been reported as recently as 1948. Similar beings are also found in Welsh, Norse and American folklore.
