If you go to a creepy hotel that inspired a really creepy book and a creepy movie about that book, you're probably going to see some really creepy stuff.
Yau took a panoramic image of the the lobby and grand stairwell during his stay. He told Fox News he waited until the stairwell was clear to take the photo, but it seems a ghostly guest might've slipped in.
The figure of what looks like a woman can be seen standing at the top of the stairwell.
If that's not creepy enough, a paranormal activity specialist told KUSA: "I immediately saw a second anomaly just to the left of the first figure. ... To the left of her, it looks like what is a child."
According to the hotel's website, the paranormal activity isn't unusual. It reads, "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."
Luckily, a tour guide told Yau the hotel's ghosts are friendly. So maybe next time, say hi?
