She came out to play — and petrify.

A 134-year-old talking doll invented by Thomas Edison managed to spook social media users — who called it “horrifying” and “the stuff of nightmares.”

Before Halloween, the National Park Service posted a Facebook photo of the doll, on display at Thomas Edison National Historical Park in West Orange, NJ, one of the famed inventor’s earliest creations.

They also added a link to the eerie audio of the seemingly innocent toy — with blonde curls and blue dress — and users were horrified, with one calling it “the creepiest voice you will ever hear.”

“The doll and her voice are TERRIFYING,” another wrote.

“That voice is no doll, that’s a danged demon,” someone added.

“Coincidentally, Edison invented the light bulb shortly thereafter. And never turned it off again at night,” another quipped.

“I’ve never heard anyone say, ‘Oh, she’s so cute,'” archivist at Thomas Edison National Historical Park, Leonard DeGraaf, told The Post.

Edison, an Ohio native who moved to West Orange, NJ, in 1886 and whose legendary lab and residence are preserved at the historical park — created the doll in 1890 after he invented the phonograph.

It has a mini phonograph mechanism inside its body that plays roughly 20-second recordings, which varied in each doll, but included songs such as “Mary Had a Little Lamb,” “Twinkle, Twinkle, Little Star” and “Baa Baa Black Sheep,” along with the prayer, “Now I Lay Me Down to Sleep.”

“They produced about 10,000 dolls and only sold about 2,500,” said DeGraaf.

“These early recordings, if you weren’t in the room when the recording was made, you’d have a hard time understanding what was said,” he said.

The doll made history as the first commercially-produced recorded-audio entertainment device in the world — and the women who taped their voices are thought to be the first paid recording artists.

“We had never before been able to record a human voice or a sound on something, store it, and then play it back. So the whole concept of it was just astonishing to people,” DeGraaf said.

The dolls, which sold for $10 undressed and between $12 to $20 clothed, were considered “quite expensive” at the time.

“They were sold by mail order, but they were also sold in higher-end toy stores. Actually one of the stores in New York was Schwarz Toy Bazaar in Union Square, which you may know better as FAO Schwarz,” he said.

The dolls were taken off the market after only two months because “they were costly and prone to breaking down,” DeGraaf explained.

Some Facebook users thought they were pulled from shelves for a more obvious reason.

“I don’t think it was because the phonograph was too fragile for kids to play with,” one said. “It had to have been that it just sounded frightening and gave them nightmares!!”
