Haunted doll

A haunted doll is a handmade or manufactured doll or stuffed animal that is reported to be cursed or possessed in some way.
Origins.
The earliest haunted dolls were poppets, effigies and voodoo objects which were created by early peoples for either religious or ceremonial purposes. These traditional objects were later acquired by various civilizations for mystical purposes or the occult. In Rome, dolls were used quite often in magical rituals to represent a connection with a god or goddess. Egyptian priests and magicians often used poppets for ceremonial purposes, to free the body of evil or to place curses on those who went against the will of the Gods.
According to Wiccan beliefs, poppets have been used to place curses on members of a community, for religious, or traditional purposes. Some of the earliest effigies were used by African, Native American and European cultures. The European poppet has its roots in early Germanic and Scandinavian tribes who used them for ceremonial purposes. Modern day Wiccans have adapted this practice for their own uses. Most Wiccans believe a poppet is a symbolic representation of a person, and spells and other actions are performed on the poppet to transfer whatever might be affecting the targeted individual out of their body in something like a healing ritual. The Kongolese "nkisi" statuettes, and the "bocio" figurines used in Vodun traditions of Benin and Togo, are traditional effigy-like dolls of West and Central Africa believed by their practitioners to be "spirit embodying" forces that can also "heal or protect". Voodoo dolls are fairly modern novelty items. Their concept is thought to be based on European poppet dolls.
West African fetish magic.
Fetishism is defined by "Merriam-Webster" as worshiping an object believed to have magical power to protect or aid its owner. In West African culture, they used dolls placed inside or around homes, and for every wish or harm inflicted on another, a nail was driven into the doll's body. Additionally, chicken blood and other various liquids were often poured on the doll's body, and are described to have a malevolent ambience. Due to the alienness of African culture, Europeans in the 16th and 17th centuries grew to be wary of these objects and believed they were evidence of sorcery.
Psychology.
Research around why people perceive dolls as "creepy" has been conducted with some varying conclusions. A 2013 study by psychologist Frank McAndrew named doll collecting as one of the creepiest hobbies an individual could have. Of the topic of creepiness McAndrew stated that it was related to uncertainty, as something "might be dangerous but you’re not sure it is". In a 2015 article for Smithsonian.com, writer Linda Rodriguez McRobbie stated that "Dolls inhabit this area of uncertainty largely because they look human but we know they are not". Since the doll lacks ability to mimic, human brains at the most basic evolutionary tactic remain suspicious of whether or not it is human since they may expect the doll to mimic their own actions. This leads to feelings of physical coldness when the doll does not act the way one thinks it should.
The market.
As of 2017, a market has arisen where consumers search for dolls that come with supposed paranormal phenomena. Films about certain dolls, like Annabelle, have created a desire to explore claims of haunted dolls. According to Katherine Carlson of "The New Yorker", such dolls bring with them a certain fascination that a regular doll does not, since "a haunted doll requires proof — or at least enough of a backstory that a prospective buyer can embrace the possibility of the supernatural". The dolls are typically sold by private users and can be found for sale on eBay, Amazon, Etsy and many other sites. Carlson reports that sales listings are often accompanied by stories and claims detailing the background of the doll and claimed paranormal phenomena. Folklore professor Libby Tucker purchased an allegedly haunted doll for discussion in her "Folklore of the Supernatural" class, and said that the value of such items for folklore researchers is considerable.

Haunted dolls have also made appearances in TV. In an episode of "Ghost Adventures" they visit a haunted Island of dolls. Additionally, a murdering haunted doll named "Talky Tina," appeared in "The Twilight Zone." The doll was inspired by the real life toy "Chatty Cathy."
