Well the most supernatural thing happen to me is this.
Back when I was 13, my family was moving out of this house and were planning on moving to a new state. Anyways one night when everyone was upstairs packing, I was taking something down to the garage. I was the only one down there. I don't remember why, but I suddenly turned around for some reason (don't remember if I heard something or what, but for some reason, I did turn around from where I was walking). There stood something that looked like a little girl, she looked extremely pale from what I saw and was just plain white. I saw it for a second or two and ran out one of the doors, towards the stairs. At the corner of my eyes, I saw it running the opposite direction towards the back door.
About five minutes later, I got my step brother to come down with me. The white girl wasn't there, but the back door she ran to was open wide. Which was another weird thing because the back door was always jammed and was difficult to open with just one person.
