Not sure if you guys experience it but I’ve had those “corner of the eye” sightings several times in my old house. I was staying in a 4 room flat in Hougang in the late 80s, which was built on the site of a cemetery I heard. There are two abandoned cemeteries near Serangoon that side which is very near to our neighborhood. The tombs are barely legible now, and the whole place is covered in brush and in the grass.

One time, I was sitting here at the computer and I saw someone out of the corner of my eye open the door to the room, look in at me, then close the door again. Since I live alone with my dog, I was quite surprised, got up quick and checked it out, but there was no one in the living room. If they’re thief, I would had heard them coming in but there was no noise at all. When I was a little kid, I once saw a lady in cheong sam dress carrying a basket. She was sitting on a bench near a playground, knitting something. Actually, my sister was there with me and saw her too and we were startled and looked at each other, I mean that time was around 10pm, it was quite a spooky sight. Then when we looked back over there she was gone, along with the bench. I know I didn’t dream this up, because I’ve spoken with my sister about it recently, and she remembers it just as vividly as I do.
