During one summer it was me my older sister and my cousin Eric. He had come down for the summer and the basement was our little hangout at the time.
We were just downstairs in the basement playing cards and talking then out of no where everybody had gotten quiet and I did not know why. A second later I heard a little girl voice say "look" or "look back there" in my ear, and then my older sister said she saw a black shadow go past my shoulder. So I look in the back of the basement, mind you no one is back there and the lights are off in the back, and then I hear a nail of some sort get dragged across one of the workbenches we have in the back. And then we all hear a ping on the ground look at each other and ran upstairs cause we were scared.
Then 15 minutes later we go back downstairs and check in the back on the floor to see if anything is on the ground and one single nail you would screw to the wall was lying there. We all looked at each other and ran back upstairs and did not bother to turn the front light out. We tried to tell my parents about it but my mom kept denying it saying there was no such thing, but my father he believed us cause he had said he experienced some paranormal events in this house. My mom had said once she saw a white shadow of a little girl in her bedroom doorway but she keeps denying it was something paranormal and she had come up with an excuse for it. To this day she still will not admit that paranormal occurrences can happen. I still get scared going in my basement.
