Kim Kardashian is 'freaking out' after spotting mystery shadow in her selfie

Is Kim Kardashian experiencing her own American Horror Story?

The Kardashians star did a double take after noticing an eerie shadow in the background of one of her recent selfies.

"Soooo I took this pic last week when I was alone," Kim explained in a July 9 Instagram post, "and now going through my phone I am freaking out noticing a woman in the window."

Fans quickly took to the comments to weigh in. Some offered an explanation. "It's just your reflection," one commenter wrote. Added another, "Your shadow from the sun." Others provided supernatural suggestions. "Looks like an alien!!" chimed in a follower. Guessed another, "Omg it's a ghost!!!!!"

And some social media users took a page from the Kardashians' book. "This is a case for the FBI," one wrote while quoting Kim's mom Kris Jenner. Referencing Scott Disick's famous prank, another commented, "Hi Kim! It's only me, it's Todd Kraines!"

While this answer remains a mystery, one thing is for sure: It's good prep for Kim's latest role, given that she's starring in season 12 of American Horror Story with Emma Roberts.
