I heard this story from my friends. One of my friends said that her neighbour died from heart attack when he saw a pontianak. He was on the haunted bed in the hospital as he was sick where it was said that a pregnant lady died. Her husband did not put an onion under her armpit. So from that day onwards, it was said that her ghost roamed the ward where she last stayed. Once a staff, saw a woman in white circling the bed!!
It is a true story. Which hospital was it?? I do not know.
