Warning: You might want to sleep with the lights on after seeing this.

While taking a “spirit tour” at the famous Stanley Hotel in Estes Park, Colorado, the Mausling family may have captured a photograph of two ghosts while they were stopped on a landing of the hotel’s stairs.

John Mausling and his wife, Jessica Martinez-Mausling, were visiting the 108-year-old hotel in September, and decided to take the tour along with nine other guests, HuffPost reported. The couple took pictures along the way, and when they got home, they notices two distinctly young-looking (but blurry) little girls on the staircase that they did not remember.

Just one problem: There were no young girls on the tour that night.

“After viewing the photos later we noticed the ghost girl walking up or down the stairs, I think the girl is walking up based on her shoes,” Mausling told Travel + Leisure. “I took several photos that night some coming out foggy some coming out sharp not sure why some were clearer than others.”

In case you are having trouble locating the apparitions, one ghostly white-ish figure is on the stairs, looking into the landing area, on the right-hand corner. The other “ghost” is a blurry figure, seemingly going up (or down) the stairs on the left.

“Assuming that it’s not doctored, it ranks up there as one of the best photos of possible paranormal evidence I’ve seen,” Ben Hansen, the host of “Fact or Faked: Paranormal Files,” told HuffPost. “If it is faked, I’ve got to hand it to them for their level of detail and creativity because there’s usually enough easy signs to suggest hoaxing.”

The Stanley Hotel is actually famous for ghostly sightings and experiences. So much so that Stephen King was inspired to write “The Shining” after staying there in the 1970s.
