We talk about entities on the main website and some of the books recommended are about Lorraine Warren and her spouse. They're the ones who worked on the Amityville house (yes, THAT Amityville house) way back when. Fate magazine has an interview w/ one of the kids who lived there then (of course he's all grown up now) who's provided some additional information into what was actually going on in that house.
