This happened to me when i was 15 years. You see my friends like to hang around at my friends house. And coincidencely, my friends house was facing an underground tunnel. That tunnel was exiting towards ST Micheal roads, and guess what!!!!! There, i saw someone jumping around in white gown. Goosebumps were all over me. I saw it and just kept quiet about it. But my pal SHAHIZUL knew what i saw coz he saw it too.....
From that day onwards, we never use that tunnel again, only in the morning. Who knows it might still be lurking around there........
