Many People Died in the Building I Live In

Because the rent was cheap, I moved into an old apartment that was about to be demolished. The landlord only reminded me: don't open the door after four o'clock in the morning. I didn't take it seriously at first, until the first night I checked in, I saw a woman who shouldn't be there on the elevator monitor that was out of service. Later I learned that many people had died in this building. What's even more terrifying is—— Some people are obviously dead, but they are still living here.
