The home had been in the same family for generations and many of them had died under mysterious and horrible circumstances. Several children were also found drowned in a nearby creek, one was murdered, and a few of them were found hung to death in the attic.
According to the Perrons, it started out small. Carolyn would notice that the broom would go missing or seemed to move from place to place on its own. She would also hear the sound of something scraping against the kettle in the kitchen when no one was there. The girls would also notice spirits around the house, though, for the most part, they were harmless.
The demonic spirit that was depicted in the film, Bathsheba, was the worst of them all. As it so turns out, a certain Bathsheba Sherman did live in the property in the mid-1800s. She was rumoured to be a Satanist and there was evidence that she had been involved in the death of a neighbour's child. The Perrons believed that it was her spirit that tormented them.
Over the ten years that the family lived in that house, the Warrens made multiple trips to investigate the unexplainable events. They also conducted a seance to rid the house of the demonic spirit. After the seance, Roger kicked the Warrens out, worrying about his wife's mental stability.

Peggy claimed that went she to settle them down, she found them huddled in a corner with terrified expressions on their faces.
After a few more unexplainable incidents, they sought help from their neighbours, Vic and Peggy, who too claimed to hear strange noises coming from around the house. When the strange incidents continued, Peggy called a popular publication to investigate the supernatural occurrences.
The publication called the Society for Psychical Research (SPR), who sent Maurice Grosse, a paranormal researcher to investigate the case. During his stay at the house, Grosse has said he witnessed more than 2,000 different incidents of supernatural nature.
It was during this time in the house that the supposed poltergeist started speaking through one of the daughters, Janet. The young girl would often go into a trance-like state where she would speak in a deep, scratchy voice, claiming to be the ghost of a man named Bill Wilkins, who had died in the house years before.

According to her, the doll swiftly made its true nature known and became a real nightmare for the girls. It started out small - a hand movement here and there. There could've been a logical reason for that. But after the movements of the doll increased, their explanations dried up.
They claimed that notes started appearing around the apartment only a few weeks in. But, the girls had no idea where it came from. Each note had a different message - 'Help Lou' and 'Help us' were just two of the terrifying scrawls, seemingly in a child's handwriting. One day, Donna saw that the doll had blood on her hands. It was the final straw and they proceeded to call in help. The medium which they hired informed them that the doll had brought the spirit of a 7-year-old girl, Annabelle Higgins into their apartment.
Reportedly, once, when Donna's friend, Lou was staying over, he seemed to be unable to move. He glanced down and saw Annabelle at his feet. The doll began gliding up until her hands around his neck, trying to strangle him. Ed and Lorraine were summoned at the recommendation of a local priest who then locked the doll up in their occult museum.

Between 1975 and 1976, Father Ernst Alt and Arnold Renz performed 67 exorcisms on her during which she would scream, thrash, and bark. Anna stopped eating and would also bang her head against the floor.

Under the cover of the night, the Bean clan would ambush travelers, robbing and murdering them. The bodies were taken back to the cave where they were dismembered and prepared for dinner.

Although at first, they assumed that Eugene was simply answering himself in a changed voice. But, they later realized that it was the doll who was returning the speech.
The family claimed that the doll would emit a terrifying giggle and would often catch glimpses of it running from room to room.

Thomas claims that he'd feel a huge presence in the room and when he'd pray, he'd notice that her face would apparently become distorted. She'd also speak in a language that was foreign to him. She'd spit and hiss while having the look of a serpent in her eyes. Once when he laid a crucifix on her, she let out a huge scream confirming his belief that she was indeed possessed.
The film: A teen girl finds herself besieged by an evil supernatural force after she plays Ouija with two classmates.
The true story: The film takes cues from the so-called 'Vallecas Case', which took place in a small suburb in Madrid. It revolved around a teenage girl called Estefania Gutierrez Lazaro who died mysteriously in 1991. Her parents were convinced that her death had something to do with her interest in the Ouija boards.
According to a report by The Sun, Estefania held a seance at her school to contact the boyfriend of one of her friends. However, it was interrupted by a teacher after which her parents claimed that they saw a strange swirling smoke enter her nose and mouth. She apparently began having seizures and hallucinations days later. The parents claimed that over the subsequent months, doors in the house would slam of their own accord, shadowy figures would lurk around. Even a photograph of Estefania apparently burst into flames with no explanation whatsoever.
Over one year after Estafania's death, her mother felt that someone was grabbing her feet, but there was no one around. The father would also sometimes notice his son being picked up and thrown on to the adjacent bed. Police Inspector Jose Pedro Negri who was investigating the case in a 2012 documentary revealed that when he first entered the room, he saw the crucifix turn upside down and the door had three to four deep scratches in them as if someone had clawed deep into the door.
The film: A young family are visited by ghosts in their home. At first the ghosts appear friendly, moving objects around the house to the amusement of everyone, but they soon turn nasty and start to terrorise the family before they 'kidnap' the youngest daughter.
The true story: The film was based loosely on the events experienced in 1958 by the Hermanns, a family from New York. Over the course of a two months, the family watched bottles exploding and caps flying across the room. A statue of the Virgin Mary did the same, breaking a mirror clean across the room as it struck it. The most dangerous of them all was when a large bookcase was pushed over by unseen forces.
Ultimately, they called the police, who sadly were of no assistance. Ironically, one of the officers was nearly hit by an airborne globe. They then sought help from a local priest. It's unclear as to whether the priest was able to eliminate the poltergeist from the premises, but the haunting did eventually stop in March 1958.
The most commonly held belief is that the family lived atop a Native American burial ground which would explain the paranormal occurences.
14. The Mothman Prophecies
The film: A reporter is drawn to a small town to investigate a series of strange events, including psychic visions and the appearance of bizarre entities.
The true story: The film is based on the 'otherworldly' occurrences that took place in West Virginia from 1966 to 1967. On December 15, 1967, the Silver Bridge collapsed killing 46 people. What caused the bridge to collapse wasn't a mystery - a crack in the bridge link led to the catastrophe. But the real mystery was the appearance of a strange visitor that was sighted several times by the citizens. The visitor ever since was dubbed the Mothman.
The Mothman first made it to the news when a couple who were driving down a highway claimed that they came face-to-face with a creature that was seven-feet-tall with large red eyes and a 10-foot wingspan. Terrified, the couple headed back to the town, travelling at almost 100 miles per hour. All the while, the creature cruised along the ground right behind them swiftly soaring fifty feet above their car.
The film: 3 college students take a road trip into Mexico for a week only to find themselves captive to a group of satanic Mexican drug smugglers who kill tourists and who are looking for a group of new ones to prepare for a sacrifice.
