Main Page | See live article | Alphabetical index In Irish folklore, Sluagh are the spirits of dead sinners; sometimes the spirits of pagan ancestors, but usually troublesome and destructive. They fly in groups like flocks of birds, coming from the west, and will try to enter a house where someone is dying to take the soul away with them. West-facing windows are sometimes kept closed to keep them out. This article is from Wikipedia. All text is available under the terms of the GNU Free Documentation License.
