This freaky incident happened many years back while I was in primary school in the western area of Singapore. It was our school 'tradition' to have a remedial camp for all graduating Primary 6 students. Where we stayed over for 2 nights. We had the usual remedial class during the day and other team bonding games in the evening. During the first night, we had to sleep in the classrooms. These rooms were not air-conditioned then. As with all kids, we were trying to frighten each other by telling horror stories. We were so engrossed when suddenly we noticed 2 ceiling fans above us stopped. One of the braver boys stood up and fiddled with the switches but nothing happened. As he walked back to our group, the fans turned on again. We freaked out immediately because the fan switches were not on! We scrambled with our belongings and left the room immediately to join our other classmates next door. We heard the room was haunted years later as it happened to our juniors as well.
