This happened about 2 months ago. My family had to attend a wedding. So we got ready about 7 p.m. And decided to leave. We were just 4 people so we took our car to reach the place. We had a good time there with our relatives and friends. "I think we should leave now, you and your brother have school tomorrow" my dad said. So I said yes and we left for home.
We finally reached home. Everybody was exhausted and looked sleepy. I looked at my watch, it showed 11: 43 p.m. We slowly moved out of car, entered home and changed our clothes. My brother and parents fell to sleep quickly. I,on the other hand watched t.v. For a little and then when I was about to go to bed I realized that I left my cell in the car. I didn't want to disturb my parents so I picked the car's key and quietly moved out of the house. We parked our car a little away from our home as someone else had already parked his car at our place. As I walked towards the car, I could feel the silence in the street. There was literally no one in the street. I reached my car, unlocked it and entered and close the door. There on the dashboard I found a phone, it was my dad's. A smile came across my face. Then I started looking for my phone. I couldn't remember where I kept it so I searched here and there, but couldn't find it. I started looking down on the mat when suddenly someone banged my window. I moved my head up and looked outside the car. Nobody was there. I was sure someone banged because there were impressions of someone's hand left on the window. I wondered for a little but then again began searching my phone. When I failed to find it, I took my dad's phone and dialled my no. I heard my phone vibrating but it was very faint. I was not able to tell from where it was coming. I again dialled and again my phone's vibrating sound came. I looked for it here and there but didn't find it. I got a bit puzzled. Then out of nowhere, again someone banged the window and this time harder. I looked outside again and like before there was no one. Now I was scared, I started sweating. My breathing became fast. I decided to not leave the car and completely locked all doors and shut my eyes.
After about 4-5 minutes I calmed down a bit, opened my eyes and looked outside, still no sign of a person there, just complete silence.
Then gathering some courage, I again dialled my no. This time someone picked it up. I was taken aback by this and said hello. It was my brother on the other side. I got some relief listening to him. He asked me " where are you?" I told him that I left my phone in car and had gone to take it, I asked him where is he right now? He replied "when we reached home after wedding, I saw you leaving your phone behind in car so I picked it up and brought it home and forgot to tell you" I was shocked hearing this. Few minutes before I heard my phone vibrating and I started arguing with him just then my attention went on the handprints on the window caused by banging. I looked into them for sometime and then I realized something and started screaming. What I realized was that handprints on window were not from outside the car but from the inside. I started panicking, opened the door of car in hurry and rushed to my home screaming. My brother met me at the door and asked about my state "what happened, I heard you screaming on phone?"
I told him about all this but he didn't believe and instead focused on calming me.
I even told my parents but they also didn't believed it and called it hallucination due to tiredness and daydreaming. Only I know this was real and this incident still gives me chills.
