I can't pinpoint the exact location but if you see deserted bungalows in Bangsar area, they're most probably haunted. Especially those on the hills.

As a person who is consistently surrounded by these things every week, I suggest you dont look for this kinda things. Shit does happen, man. When it happens to you, you'll be wishing you hadn't gone looking for it. Ever seen a Pontianak staring at you back? I got knocked out cold for a night, bro.
