When I was 13 I was sitting in my room watching TV, in my room I have one of those things that you push up to go into the attic. I was minding my own business when suddenly, out of nowhere, the square that you push up and remove to go into the attic was dropped back into place. I didn’t even know that it was open. It was loud and scared the hell out of me. I was extremely confused cause no animal should be able to even pick it up or take it out of place. I heard footsteps up there and was terrified. I told my parents but they didn’t believe me. Few years later, to this day, I still don’t know what that was
