My door

Ok so this story may not be to interesting but it’s still a horrifying memory for me- a couple of years back when I was about either 6 or 8 I was in my room watching tv. There was this creepy ass epsiode of Sanjay and Craig playing so it did not help my mood at all when out of no where my door starts violently swinging back and forth. Like consistently same speed everything and moving wall to wall (if that makes sense) My hallway had none of the lights on so it was extremely dark but you could still tell if someone was there because the light from the living room downstairs would somewhat illumnate them. And if someone was swinging the door I would’ve seen them swinging it because theres no way someone could have swinged it they was it was. And it was definitely not the wind because 1. I would have felt the wind and 2. The wind would have had to been violent for it to be swinging the door the way it was. But there was no way strong wind and couldn’t have gotten in since it wasn’t even windy and my weak ass fan was facing me not the door(it was on its lowest setting) this goes on for a bit and I’m yelling for my dad so after being fucking scared half to death he comes and puts a plastic dresser?(idk proper word to describe it) on my door to keep it from moving and something like that never happened again.
