A Houston man staying at one of the nation’s most famous haunted hotels has an unusual souvenir from his trip.

Henry Yau, the public relations director for the Children’s Museum of Houston, was staying at The Stanley Hotel in Estes Park, Colo. with his wife for a weekend getaway. During his stay, Yau took pictures around the historic property—which served as the inspiration for Stephen King’s “The Shining.”

But he hadn’t planned on seeing anything out of the ordinary.

“I had read about it being haunted but little did I imagine I would capture something,” Yau told FoxNews.com.

While Yau was in the lobby, he used the panoramic feature on his iPhone to capture a full view of the grand stairwell.

“I don't like when people are in my shots, so when I took this photo, I had waited until the grand stairwell was cleared of people before taking the pic,” he recalled.

That night when Yau went to bed he says he became “strangely ill.” Feeling uncharacteristically queasy, he didn’t sleep well. But the real surprise came when he was scrolling through his hotel shots the next morning.

When he looked at the photo the next morning, Yau was startled to see a figure at the top of the stairs. Yau posted the photo on Facebook with a red circle around the unidentified mass, captioning the creepy image "By golly! I think I may have captured a #ghost at #StanleyHotel. #EstesPark.”

“I honestly don't know who this figure could be,” said Yau. “When I was there, I took a historic tour and they said all ghosts who roam there are happy ghosts. So I'm hoping this one was a happy one.”

Built in 1909, the legendary hotel hosts different ghost tours after gaining a reputation for being haunted in the 1970s.

"After a century of collecting spirits, the hotel has become renowned by specialists and experts in the field of paranormal investigation as one of the nation's most active sites," according to the Stanley’s website.

After Yau’s spooky vision, he concurs that the property is definitely a hub for unusual activity.

“The Stanley Hotel is a hotspot for anyone interested in ghosts. There really is something there and I'm now a true believer.”
