I really need your help on this, so please bear with me if I'm not as good as other writers in describing what happened. This happened 2 or 3 months ago.
I was on my laptop, reading stories on here when all of a sudden I felt like I needed to use the bathroom. I closed the site and went to the bathroom; half way through my business I heard singing. Not singing, more like humming. The type of humming that a lady will do when she's sewing. I wasn't scared; I just sat there fascinated by how beautiful the sound was. After a few minutes it stopped. I went out of the bathroom and ever since then everything has been quiet until now.
It was my sister's birthday and she was going to the mall with her friends so it was only me and the housekeeper. I was sitting on the laptop on the dining table and next to me was the sofa the housekeeper was sitting on. After 15 minutes, she asked me if I heard anything, I told her no. She told me that she heard the door unlock (it was locked, I'm 100&% sure I locked it myself!) and that when she looked the door was open! I told her that there's probably something wrong with the lock. Half an hour later, I went to my room to watch TV. While I was watching TV, the door slammed shut by itself. This was the same door that I mentioned in my previous story.
