My Story: I've been to the old changi hospital quite a number of times and i'm sure you can get others have gone there more than once to vouch for me. This isn't a story rather it is about the spirits that still wander in that decrepid building.

There are 6 spirits wandering there(to my best knowledge) and where they usually are...An old man on the second floor of the main building usually walking in the corridor...A woman wearing a baju kurung in the building to the right of the main building and at the linen or laundryroom...A nurse also in the same building as the baju kurung woman...Spirits of children at the childrens ward section to the left of the main building which can be reached by the long staircase on the hill before the gate/barricade... Behind the hospital there is another house with a plastic/glass door which is full of rooms. It is haunted by japanese war ghosts...And finally the commando camp up the hill behind the hospital(it used to be abandoned but now they've started using it again so don't go there unless you want a bullet up your ass) is a place where the pontianak fly freely and usually not by herself...So if you really wanna see these spirits just go to the places i wrote above with no more than 4 people including yourself and just sit down switch off all your torchlights and put out your cigarettes and i promise you that 5 mins after you sit down the "show" will begin...trust me.
