112 Ocean Avenue is perhaps one of the more famous examples of a recurring yet notoriously hard to classify a breed of villain known as the "Possessed Object" - in this case a house which most come to know as both the "Amyville House" and also "High Hopes": although it can be argued that the true antagonists of the Amityville Horror where poltergeists or demons there is also a school of taught (especially in the movie series based on the events) that the house itself was somehow alive, making it a villain in its own right.
112 Ocean Avenue is a real location in Amityville though the locals dislike the attention the Amityville Horror brings to their neighborhood and as such have renamed the house as well as redesigned it: in the movies 112 Ocean Avenue is infamous for its demonic windows that resemble glowing eyes - the style of architect this building was originally is described as Dutch Colonial.
In the movies, 112 Ocean Avenue was said to be isolated but in reality it was within 50ft of other houses and the story of the Amityville Horror is deeply controversial even to this day: with some claiming that it was a demonic phenomena and others claiming it was a hoax.
Regardless of what truly happened at 112 Ocean Avenue, one thing is known for certain, this home was the location of a grisly mass-murder by Ronald "Ronny" DeFeo Jr. in 1974 - this massacre is widely claimed to have given the location its curse (though in the films it is suggested that DeFeo was possessed by the house into committing these acts).
Supernatural events that are attributed to 112 Ocean Avenue includes swarms of flies, an invisible "imaginary friend" that turns out to be some kind of demonic pig, spouts of madness and violence in people that stay too long, poltergeist activities such as rattling of windows and slamming of doors: a priest who came to bless the house reported hearing a dark voice (possibly of the house itself) yell "GET OUT!" and many people felt ill by going near the building.
Unpleasant sights and smells would appear on and off in varied parts of the home and the basement was said to have a mysterious "red room" that was not part of the home's blueprint - perhaps a manifestation of the house's true-nature.
Most disturbing of all was claims that green slime would pour out of the walls (changed to blood in the movies) and a crucifix hung on a wall was found turned upside down - making it a Satanic symbol.
Criticisms of the Amityville Horror have been the similiarities between the demonic phenomena described in the book and those found in stories such as The Exorcist as well as the fact that the new owners of 112 Ocean Avenue have never experienced malevolent forces (then again the new owners do not discuss the Amityville Horror as they, like most residents of Amityville, dislike the publicity it receives)
112 Ocean Avenue has been heavily altered over the years and bears little resemblence to the haunting building seen in the movies or book yet the original house will always stand as a symbol of one of the most unusual and disturbing ghost stories of American lore (at least in modern times).
It is also worth noting that in the film series (prior to the remake) 112 Ocean Avenue was eventually destroyed but the evil of the house remained active long after this event and went on to possess varied objects and people - including a dollhouse that heavily resembled the original.
- This is a fictional speculation, and is based loosely on a claim made by the parapsychologist Hans Holzer that the haunting was caused by a Native American chief whose body was buried on the site of the house.
- In the 2005 remake of The Amityville Horror, the history behind the house on 112 Ocean Avenue in Amityville which was once originally called "The Sanctuary", was revealed with facts about the site and the cursed spirit of a dead man named Jeremiah Ketcham (fictionalized version of the real-life controversial figure John Ketcham) who haunts the house.
- Jeremiah Ketcham, a 17th century reverend, moved to Amityville during the summer of 1673 and completed the first construction of his property by the late autumn of that year as he soon began his missionary work with the Native American inhabitants of that area.
- During the 17th century witch trails, Reverend Ketcham advocated extraordinarily cruel and outlandish methods of torture for the "witches" within the Amityville area. And his suspicions fell upon not only those already convicted of witchcraft, but also on established members of the community. In 1670, he stood trail for extremism. With some of the community members suggested that Ketcham himself was a warlock, a male witch.
- In the film Amityville 1992: It's About Time, the house in Amityville, according to Rusty Sterling's dearest neighbor and local psychic Iris Wheeler, was Jean Delae, a 15th century?.
