I actually had a real deal supernatural experience. My sister had gotten a house once and my family and I stopped by to drop off some furniture and help spruce up the place before she moved in. She didn't have power so we were getting ready to call it quits because it was late and it was getting to be pretty pitch black in the house. Everybody walks outside but there was something that got left in one of the bedrooms and my mom told me to go and get it. I was already kinda nervous because as it got darker the house just seemed sort of creepy and it felt like a presence was watching you. I made my way to the master bedroom in the back to grab an item and as I was back there I remember looking at my sisters bedroom set which was in this huge box that was like chest level height. There was a screw driver sitting on the edge of the box, about 7 or so inches away from the very edge. As I was getting ready to leave the room, suddenly the screw driver just rolls over the edge of the box and lands on the floor. it sent chills up my spine and I paused for a second before getting out of the house. The boxes surface was flat and there was no incline or breeze so the screwdriver apparently just decided to mess with my head.
Months later after my sister had long moved in with her husband, I would occasionally come over to spend a few nights there. her house was kinda like a party house and lots of friends and family would come over and we would basically smoke copious amounts of weed, drink, all sorts of stuff of that nature. I put the incident in her room that happened behind me and basically all but forgot about it. My sister and her husband went out of town and had me my cousin and one of my friends watching the house. We were screwing around just doing dumb shit the entire night. Now we stayed up all night and the sun had come up. My friend and my cousin were getting sleepy and I was somewhat an insomniac so I went to my sisters bedroom to go watch TV since she had a huge flatscreen back there. I sat on the bed and began watching tv for about 5 or so minutes when suddenly her bedroom door just closes, it blew my mind. When I saw that immediately in my head I went back to the night the screwdriver fell off of that box and I get up and dart out the room to see if my cousin or friend were playing a joke on me. Each of them were asleep and had been for some time. I came to the realization that my sisters bedroom was haunted. I didn't go to sleep but it wasn't only out of fear, it was also out of amazement, I actually saw proof of something that most ppl would claim isn't real. I saw it with my own two eyes, it definitely wasn't a breeze that closed the door. Later on more stuff such as closing doors would happen but we got used to it, it rarely happened and whatever was in the house didn't feel evil. It seemed to love letting ppl know it was there from time to time though.
