Have you ever experienced something paranormal? [I Am Interested In the Paranormal]

I have experienced a few things. Nothing scary...sometimes slightly unsettling. My sister and I went on an investigation in a local theatre. She got pushed through a door at great force by something. I saw her fly. Evertone else was on the other side of the door....which was at the top of 8 steps. She landed on the floor at the bottom of the steps and cracked a bone in her back! It was enough proof for her that there was something unpleasant there. She's never been on another since. I have a visitor in my kitchen at present....but its not threatening in any way
