These horror films were scary enough in theaters, but the true events they're based on are even more terrifying. Warning: You might want to leave a light on.
'Psycho,' 'Silence of the Lambs,' and 'The Texas Chainsaw Massacre'
All three films are said to be based on the crimes of one man -- Ed Gein of Wisconsin. He never left his home, never went on dates, and was devoted to his mother, so when his mom died in 1945, Gein pretty much snapped.
He began trolling around graveyards at night, stealing female corpses, and dismembering the bodies. Gein displayed some of the parts in jars around his home. He would turn others into furniture, and he even used the skin to make a suit.
But corpses weren't enough for Gein, and he soon turned to murder. That’s when police started investigating the reclusive man, and discovered his sick secrets.
Gein was convicted of killing two young women by reason of insanity and died in prison.
The American couple was accidentally left at sea during a scuba-diving excursion off the Great Barrier Reef, but it wasn't until two days after the trip that the Lonergan's belongings were found on the dive boat and the crew realized they were missing.
A massive air and water search immediately got underway, but the Lonergan's were never found.
The couple is presumed to have died at sea, but there is no evidence they were killed by sharks, as the movie suggests.
'The Exorcism of Emily Rose'
The movie is based on the horrifying true story of Anneliese Michel who was subjected to repeated exorcisms.
According to the Washington Post, Michel was believed to be possessed by demons when she refused to walk past a certain image of Jesus, would not drink water from a holy spring, and smelled really bad.
Court findings detail how Michel would rip her clothes off, compulsively do hundreds of squats, bark like a dog, eat spiders, coal and a dead bird, and lick her urine off the floor.
Michel went through 67 exorcisms over six months and died at the age of 23. Michel’s parents and the two priests involved in the exorcisms were found guilty of negligent manslaughter.
'The Amityville Horror'
The movie is based on George and Kathy Lutz’s experiences inside the home at 112 Ocean Avenue in Amityville, New York. The Lutzes moved into the home in 1976, just two years after a family of six was murdered inside. But just a couple months after moving in, the Lutz’s fled, claiming the house was haunted by demons.
The only problem is that the Lutzs’ tale was debunked
. The police, a judge, and a well-respected parapsychologist all concluded that the events never happened, and the couple even recanted some of their story.
The true part, however? The home was indeed the site of a violent murder. In November 1974, Ronald DeFeo Jr. shot and killed his father, mother, two brothers and two sisters. DeFeo’s motive is unknown.
The Amityville house is still standing. No other occupants have reported any activity.
'The Haunting in Connecticut'
Cameron Reed’s story was the inspiration behind the horror flick, and she talked with People
about the terrifying things her family experienced while renting the old home.
Reed moved into the house with her husband, three kids, and two nieces in the '80s. The rental had once been a funeral home, and according to Reed, freaky things started happening the very night they moved in.
Reed says demonic forces would take different forms and slap, grope, and threaten the family, her son started acting out, and the other children would beg to leave the home. Reed says it took three priests to finally rid the home of the evil spirits, but the experience has left her sensitive to the supernatural ever since.
The current owner of the home has never experienced anything unusual.
