My Story: This happened to me & my frenz sometime ago. The story took place at the Punggol Adventure Camping site.
We had a night run. We were supposed to bring a torchlight along. My friend was having trouble with finding her torchlight as it was dark in our tent. So, me & my frenz waited for her outside the tent. But she told us to go first because she was scared that we might get scolding 'coz of her. Me & me frenz agreed.
We were walking towards our group which was assembling in the field, when we heard a loud scream. We stopped in our tracks, knowing that our fren was in trouble, went back to our tent. There was my fren, shivering in fright. Her face looked pale when we shone the light to her. We asked her what had happend but she insisted that we have our run first then she would tell us.
After the run, she said that she saw a girl crying in the opposite tent and when she realized, she was going to consult the girl, the girl gave a high peircing laugh and vanished.....
