2 years ago. This happened 2 years ago when my family went for a holiday at Sabah. We checked in at an old apartment. There was 3 bedrooms in the apartment. My family stayed in one of the room while my grandmother and the maid stayed in another room. During the night, the door knob at my grandmother's room suddenly turned, seemed like there is someone outside trying to open the door. My grandmother was scared and asked the maid to check it out. When she opened the door there was nobody outside. (Memory collected at the Bukit Panjang Public Library during the "irememberGhost stories" campaign from 27 Sep to 30 Nov 2012)
