Next time you are in Singapore, go check out the Park View building. Make sure to explore the statues outside and go into the ground floor and be amazed.
I had exactly the same thoughts when I stumbled upon it wandering around the downtown late at night. It was dark, I was alone in the patio and the building front looked amazingly scary.
Though I have heard that some of the companies there have trouble retaining staff due to rumours of haunting!
