It heppend last, when my school move to old Tanjong Katong Sec Sch (TKSS). It happend to one of my chinese friends.
After our music lesson, me and 3 of my friends when to clean the room. After cleaning the room, we decided to lock her inside. After a while, I told my friends to leave but she told me to go first. When my friends went out the door, on that time her face look pale. She feel so scare. In class, she dont talk at all.
When she told the teacher, she said she saw red thing wthout head and she kick the door. She said the thing close her mouth. As i know there is a white house behind. I often see police come to girl's toilet. The school is really haunted.
