My brown Musician Window (SWC)

I don't know if this is a supernatural story or not. Heard many stories of ghosts and unexplainable stories from my father and grand father. But didn't believed and related myself to those stories. Until now.
My home is situated by facing towards west, back is to the east. The room where I have been living from my childhood is in the southern direction. I am describing the position of my house so that you can imagine its location. It is in the north-eastern part of India. The problem is the only window of my room and it is also in the south. It makes sounds! When I study in the evening there would be a sound like punching. Firstly, I didn't mind it and continued my study. But when it often began to punch in the evening, I was worried. I told my parents but as expected they only laughed at it and thought one of my excuses to bunk study. The days, years passed away like this.
This is the window
Now I am a grown up man, married and living a happy life. In early 2017 the window again came to the limelight. My wife began to hear some sort of musical sound coming through the rod bars of the window. They sounds as shaking all the time like when there is an earthquake! I was surprised that I have also heard those sounds when came closer to the window. I have never noticed it until then.
The real tragedy began when we heard someone punching, and sometimes like throwing a stone at the window. I try to look after if somebody is doing this in disguise, but got no clue. I opened and checked the surrounding just after the punching sound. Sometimes I stand outside and my wife inside to caught the source of the sound, but in vain. We dis not suceed.
Now, though I am living in a small town I think rationally. I believe in science and that everything which can't be described through evidence doesn't exist. But these incidence had brought me to a dilemma to believe it or not. And there was a peculiar behavior of the window. It makes its louder sounds, and more often on tuesdays and saturdays.
The days became months and we had no clue. My wife is also a graduate and teacher, but was desperate to get the solution. Therefore we went to a priest who was believed that he can control the supernatural forces. He had asked us the position, color of the window and meditated for some time. Then he gave us a small packet of something wrapped in a white piece of cloth. And told us to hang it on the window. We did it, and it slowly began to diminish and someday, we can't tell the exact day, it stopped to make any noise and music.
This story may be seen as chilly and I didn't believed in ghost and supernatural things, but now I have to. In Hindu philosophy it is believed that we all are souls. When a people die, the soul does not die and it simply changes its body from one person to another. And when there is some hindrance for the soul to enter a new body then it is strucked in between somewhere and in some place. The priest has told us that there was a bad soul struck in our window which was not able to find an another body to enter at its birth. Thanks to God that the miserable soul who might have finally got a new life.

This is my real story which is written because of the SWC, Supernatural Writing Contest organised by @jerrybanfield. Thanks to him. You can also vote for him for witness as I did in https://steemit.com/~witnesses.
