My Story: This happen to me when i was in secondary 2. At that time of the year, we were celebrating chinese new year. A group of my friends suggested going to a rich firend of ours to pay our respect. Everything was fine, we stayed until very late, mostly playing console games. The spooky stuff happened then, when we were about to go home, around 9 pm.
I was urgent for nature call and therefore went to the toilet. As my friend's house was rather huge, a mansion, the toilet was located at the far end of the building. I went in alone and relieve myself. Just when i was about to go out, i saw a strand of long hair falling down to the window. I thought it was a prank by my friends as his room is above this toilet at the second floor. I slowly walked towards the window and using my strength, i pull the hair, trying to pull it down. It resisted for a while, but i finally manage to pulled it down. I happily looked out the window and up, thinking they were fooled by me... but what i say was a pretty lady's head floating around and smiling.
I ran for my life as i evilish laughly trail behind me. I did ask my friends when it was their prank, but they kept saying they were playing fire cracker with his parents. Until now, i have not relate it to him, afraid that it may cause him discomfort living in his house.
