Before I arrived at my university as a freshman in 2009, I saw some rumours about the Girls' Dormitory No.18 on that bbs.
Behind No.18 is our school's No.16 dormitory for girls. Someone wrote notes on that bbs like this:
When we talked about the paranormal events, I remembered something about the girls' Dormitory No.18 in the third location (my university is in the university town. There are six locations, and the third and fourth location belongs to us).
That was a night about 20 to 21 o'clock. When a girl on the third floor of No.16 was going to hang washing on the balcony, she saw the curtain of the opposite room of No.18 Dormitory was opening. But at that time, the No.18 Dormitory had no one living there.
The story has been taken without consent; if you see it on Amazon, report the incident.
That was not the only odd thing about No.18 Dormitory. Someone said that when she returned to school on September first, she found that the aunt of the dormitory administrator was burning papers (a kind of paper which can transform into money for a ghost to spend in the underworld when somebody burned) behind No.18 Dormitory.
At that time, I just treated these as some horror stories. However, when I arrived at my university and lived in the No.18 Dormitory, I realised that these were not just as simple as horror stories. Maybe ghosts exist in this world.
