Bal

Apparently Bal could see ghosts ever since he was young. According to Bal, he once saw a pontianak sitting on the roof of the Curtin AL100 building.

Also, a female spirit was frequenting the area near his house, a terrace house in Desa Senadin, and it often went across the street to Anaesthesia's house (click here for Anaesthesia's experiences).

Bal stayed alone, and often had friends over. Once night, James and Jessica were at his house playing MapleStory.
They were drinking Coca-Cola, and suddenly they noticed that one of the Coke cans had been moved.
There were only 3 of them in the house and none of them had moved it.
Bal left the room, and James and Jessica heard him scolding someone in Malay not to disturb them. But there was no one else in the house...
