Tell me about what happened around you, paranormal?

When I was a sophomore, I got up in the middle of the night to go to the bathroom. I found someone in the toilet and shouted, "Wow, what a coincidence? Get up in the middle of the night, your stomach is uncomfortable? " As a result, people ignored me, so I turned to see which bed was empty. As a result, there were people on every bed! ! ! So I quickly woke everyone up and went to the toilet to find out. It's empty.

The dormitory structure is as follows. I'm sure that man didn't go out through the gate. Terrible!
