i was in grade 5 when this happened
first thing my classmates and i were playing around because our teacher is sick. until the lights were flickered off. but the aircon was still on. after a few minutes We heard something whisper "Psst." we all looked back where the sound came from. and the lights flicker on and our adviser saw us in one corner hugging each other like its the end of the world. our adviser asked us why and we tried to tell him but he said it was only our imagination.
