What i'm going to tell all of u is true and it happened to me on the 19 or 20th of Jan 2001.I and 5 others slept in a PSA chalet in sentosa.The whole place was very eerie but the haunted place is actually not the chalet but the vacant colonial house situated a few metres away from it....further up the hill.I woke up at 3 in the morning to join a group of 8 for the most scariest adventure of my life.We were guided by experienced ghost hunters who brought us to the house.The moment we reached the house..i could hear children's laughter followed by low howling voices.....how scarieeeeeee...we then slowly went into the house and continued to hear voices.We then went up the stairs and one of the guys(shudder) saw a figure of a guy crawling on the ceiling!almost simultaneously i saw a white figure standing next to a tree outside the house..that's when we heard the noise grew louder n louder till one of the guyz decided that we shall not proceed any further coz 'it's too c! lose for comfort'...we never did set foot in the house again.
