So when I was around 4 years old, my family moved into a new apartment house. I remember this because there was a nice old women name Nan who took care of my sister and I when my parents had to go to work on the weekends. Where we lived was the back house of Nan. The house we lived in only had 1 bedroom, 1 bathroom, a kitchen hall, and a living room. And to mention the distance between the bedroom and living room is not too far from each other.
My Mom also wears this protective chain around her waist to compel spirits/evil beings from her and those around her. Ever since she was young she had experience supernatural events from Cambodia to America. So the temple had given her a blessed chain to not let them bother her. This one night, she took it off ...
In one particular night, my Dad was had went out to do some business for work so he wasn't going to be home that night. It was just my sister, my mom, and me. My mom decides to take off her chain because it was bothering her for some odd reason. So she put it on top of the drawer. I remember it was late at night probably around 12 o'clock. I was up with my mom watching tv in the room and my sister was sound asleep. Not long after we hear a loud knock on the door. My mom was really confused who would be knocking in the middle of night. My mom thought it was my Dad coming home. I can tell my mom was a little scared, so I went with her to open the door.
We open the door. And there was nothing. Just the front light. My mom looked around and say nobody. She closed the door and she and I head towards the bedroom. Not even midway, we hear a loud BANG sound from the door. I remembered I started to get scared. My mom and I went back to the door and open it once more. She looked around, there was nothing to be seen. She closed the door again, but this time locked it. I can tell from her frighten face, something wasn't right.
We rushed back to the bedroom and I told my mom to put back the protective chain. She puts it on and there wasn't anymore knocks that night. But the next morning she goes to my Landlady Nan and tells her about last night. She described the figure she say at the door, and it was apparently Nan late husband who had past away years ago. My mom becomes frighten and she offers him some fruits that would help the ghost leave her alone.
Soon after, we moved to another home.
