We have this resin lawn gnome and so it wouldn't get ruined by the snow and the sun we have it inside, sitting on the edge of the fireplace, which is raised about ten or so inches. On the night of October 30th I walked into the living room and rounded the coffee table to get to the couch. Out of the corner of my eye I see the gnome moving and then hear a shattering noise.
Now, I can't tell you how I saw the thing moving. It was just moving. I was without my glasses (very blurry vision) and the room was dimly lit, so all I saw was the gnome moving.
A rocking/reclining chair sits about two feet from the fireplace. Its base is metal, so when I heard the shattering of plastic my first thought was that the base of the gnome broke, as if it fell it would have fallen on the head and then tumbled over to to the chair and hit it. While wondering if the thing would even stand now and how badly it broke I walked behind the chair to see that the top of it had hit the base of the chair and broke.
In order for that to happen the thing would have had to fly over to the chair and hit the metal base and there was nothing near it, other than my cat, to hit it that hard to make it fly that far. The gnome was also sitting in a round wooden base that held a ceramic figurine we no longer have and that base has a lip around the edge of about 3/8". I would think if it had been hit that I would have heard it moving against the wood or that the wood base would have moved a little, but I heard nothing as this happened.
My cat was standing near the gnome on the carpet and sniffing the air around the it before it flew off the fireplace. But she didn't really freak out or anything. She just sniffed and looked around.
Also, where the gnome was sitting was in the same place where our indoor/outdoor thermometer flew off the mantle and slammed against the window, as if someone had grabbed the wire leading from it to the outside and tugged it really hard, hard enough for the wire to break.
And in that case my dog was outside on the deck sleeping and she would have woken up if anyone had been out there.
But in both events I did not feel anything was there. The things just happened with no explanations at all.
The next day I stood in that area staring at where the gnome was and where the chair is that it hit and trying to recreate the event, but found that if the gnome fell it would have tumbled and the bottom of it would have hit, not the top. I eventually just shrugged and wrote it off as something else unexplained.
