Annabelle the Doll
Thanks to the movie The Conjuring, this doll is pretty popular, and 100% real. Annabelle was a gift to a daughter going to college in 1970. Both the girl and the roommate reported finding the doll in different positions and room in their house, and even found papers with childish writing on it. They reached out to a psychic who claimed that the doll was possessed by the spirit of a girl named Annabelle, who died in a fire, and that the spirit was benevolent. A male friend disagreed and thought the doll was sinister.
He was found the next day, strangled and scratched, with only Annabelle in the room. The girls reached out to Ed and Lorraine Warren, who were paranormal investigators, and they discovered that the doll was a conduit for demons.
After two exorcisms didn’t work, they doll was placed in the Warren’s occult museum, behind a glass that warns people not to open it.
