As much as this might seem to be utter bull**** to the multitude of people who do not believe in ghosts, all I can do is retell what I experienced.
Due to ongoing renovations in our house, mum forced me and my younger brothers to accompany her on her shopping trip. The three of us however were unwilling to spend the Friday with our mother hunting down a new pair of shoes, so we begged to be dropped off at our grandparent's house.
As much as this may seem made up, that day was the first time I left my phone back home and the irony of my mistake is something that makes me cringe every time I think about it.
So, we were standing in front of the gate, ringing the bell hoping that our grandfather would open the door. Our biggest mistake I believe was failing to check whether my grandparents were home.
After ten minutes of ringing the bell, I heard my younger brother cry out "grandpa open up!" I looked up to see our grandpa standing with his back towards the open window in his room on the second floor. We tried to get his attention but he did not move an inch.
That should've been a warning to me, since my grandfather has no problem in hearing clearly. After 20 minutes of standing in the sun I led my brothers to my grandparent's neighbour's house, hoping to be able to use the house phone and get mum to pick us up.
I rang the bell and Mrs. Stone answered it, greeting us with the common "hello" and "how are you?" She led us to her living room and inquired why we were at her house. I told her all about mum going shopping and dropping us off with grandma and how grandpa wouldn't open the door, when a confused look came over her face.
I asked her what was wrong and she said that my grandparents were actually not home. As a matter of fact, they had left the house keys with her. My brother and I couldn't make sense of what she was telling us, we had just seen grandpa at the window!
But being the superstitious person I am, I told my brother that we should just call mum. After all, in every horror movie, the actors make the same mistake and walk right into the haunted house only to be killed by an entity.
Usually my paranoia was absolutely stupid but when we told mum the story she was glad we didn't enter the house. Apparently we weren't the first people to see grandpa standing at the window with the house being empty.
I haven't been able to go to my grandparent's house alone ever since. My superstitious nature hasn't been made fun of since then though.
