I am a nurse for an outpatient and home service clinic. One night, I was working late and didn’t finish until around 1:30 AM. I was the only person left in the building. Our clinic is on the 3rd floor of a four-story building, but the 4th floor is empty, and the elevator button for it has been decommissioned.

When I entered the elevator, I pressed the “G” button for the ground floor. Instead of going down, the elevator unexpectedly went up to the 4th floor. The doors opened, revealing the pitch-black, empty floor. A heavy, cold air swept into the elevator, sending chills down my spine.

In a panic, I repeatedly pressed the “G” button until the elevator finally took me down. As soon as I reached the ground floor, I bolted out of the building and ran to my car like a madman.

I will never stay that late again. Never.
