I'm Chen Mo, the host of the supernatural radio show Whispers in the Dead of Night.
One night, a listener named Lin Xiaoya called in to describe a bizarre experience in the elevator of her new apartment building:
Her reflection in the mirror was always a beat behind, and the elevator buttons would often light up by themselves for "-18th floor."
"Last night, it really stopped on the -18th floor," she said, trembling. "There was no one behind me, but I felt a cold breath on the back of my neck."
After the show, I looked into it and was shocked to discover that Lin Xiaoya had died in an accident involving that elevator three years ago.
The next day, during a live broadcast, the hotline suddenly rang.
The caller ID flashed the same name: Lin Xiaoya.
And the date of that first eerie call was unmistakably the day she fell to her death three years ago.
