It happened when I was in pri 6. I have 6 close friends. We joined band as our CCA. In our band room, there are alot of percusion instruments lying on the floor. After our band practice which ends at about 4 o'clock, 6 of us have to do our duty, keep all the instruments and keep the room clean.

After we have locked the room, we heard drum stick falling down to the floor. At that time it was almost 6. The next thing we saw, the fan on by it self and suddenly, we heard someone was playing the drum sets. We guys were shock coz that time we were wearing our shoes and no one was in the room and we have locked the door. I don't know if this story is scary or not but this is a true story.
