I still do not know if ghosts are real. But one night in my first year of college, something happened that I can never explain. I was new to the hostel. Near our water cooler, there was a room that was always locked from outside. Around 1 AM, while watching 3 Idiots, I went to fill my empty water bottle. Suddenly, I heard someone running towards me from behind. Before I could turn around, something pushed me HARD from behind. I turned instantly. Nobody. The corridor was completely empty. Then something fell inside that locked room. And I heard a voice: "Darwaza kholo... darwaza kholo..." I could hear footsteps around me. Then loud sounds, like someone jumping inside the room. Everything felt terrifyingly real. Thankfully, I had a Rudraksha on my hand. I ran to my room, locked the door and played Hanuman Chalisa at full volume until morning. The next day, I found out why that room had always been locked. A student had died by suicide inside it. I changed my hostel building that same day. Maybe ghosts are not real. But I still cannot explain who pushed me that night.
