So I don't generally believe in the supernatural stuff, but I've had a few experiences I can't explain that still freak me out a bit.
I used to live in a 3 bedroom apartment with a rotation of 2-3 other roommates that worked out being about 7 different people that lived there during the 2 years I lived at the place. Every single one, including myself, had a nightmare experience that only happened while living there.
The nightmare wouldn't seem different from an average dream. Then you'd notice a presence like someone who wasn't supposed to be there. Eventually the discomfort of this presence would become overbearing and wake you up. Which is when you'd realize you were in sleep paralysis and hear a woman screaming loudly in your room.
Eventually you'd shake off the paralysis and have to decompress from whatever the hell occurred. But man was it strange that it happened to all 7 roommates the exact same way and was isolated to that random apartment.
Bonus experience - At that same place I once woke up to my computer turning on by itself. The monitor lit up my small room and when I woke up to see what was going on it looked like my room was filled with smoke. There was no smell of smoke, but in my sleepy haze I didn't care as I thought it was a possible fire. So I carefully touched the door handle to make sure it wasn't going to burn me. It was fine, I opened the door and it was dark and normal for the middle of the night. I turned back to my room and watched the smoke somewhat slowly disappear. I have no explanation for what I saw that night and have never had a similar experience since then.
