As I stated in my story that preceded this one, my home was only about 20 years old when I moved in. The previous owners were a family of four we never had the chance to meet. My parents never experienced anything paranormal and deny it exists.
A few things have happened since the first story I published.
I was at home alone one evening. I was sitting in my computer chair reading. My cat was resting about six feet away from me on a large easy chair. She was sound asleep. I stood up to go to get some water from the fridge when I felt a little weird, like I was being watched or something. I went and got the water, drank it and went to sit back down. But as soon as I got about a foot away from my chair, a white mist zoomed past my feet and went right through my desk, wall and disappeared. I was frightened enormously. I ran to the other side of the wall but it was gone. My cat stood, snarling, at the area it exited through. The wall was, at the time, in between me and my kitchen my fridge to be exact. Perhaps a coincidence because I was there a couple of seconds before? Maybe no, maybe so.
Another incident was when I was in the room where the book was thrown at me. I was sleeping in the bed because we had guests, and my animals were in the living room, sleeping. The door, no longer glass, opened. But this time it opened very widely and made horrible creaking noises. I didn't feel or hear anything but then I felt my bed moved a little. I felt weight on the mattress and then the sheets shifted a little. I pulled them back and made a quick "No." sound. The weight suddenly lifted and I stared at the place again. It scared me but I went back to sleep. The door stayed open, though, and it creeped me out.
