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.

Between her illness and her strict upbringing, Anna lost much of her social life and retreated into a state of depression. Eventually, she began to hear voices.

She reportedly also developed a strange aversion to religious symbols. This was the impetus for her parents' belief that their daughter was possessed. 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.

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.

Source: Silly Confusion

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 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.
