A little relevant to this story, my brother and I used a TV left there by another tenant, but the knob was missing (remember those?), so we had to use pliers to change the channel.
A few years later, we moved into another house. My brother was in my room while I read a story and complained of a bump in his sleeping bag. We finally cut it open and found the knob!! No seams broken, no hole - but it still fit the TV....freaked us out.... We were not nearly as calm as this girl with real human bones in her floor! Wow....
I used to carry a Zippo my father gave me, and it disappeared and reappeared so often that my friends and I called it "Boomerang." I would put in on my dresser or some other place, and when I went back for it, it would be gone. I got to where I just wouldn't worry about it, and pretty soon, it would turn up in some weird place.
The last time it happened, I was rooming with a friend of mine, and left it on my dresser. It was gone when I went back for it. I looked for it like I always did, in the floor, in the drawers, behind the dresser, etc., and didn't find it. When I moved out and went back to Texas, I looked all over for it. I couldn't find it.
After I left, he remodeled my room, and turned it into a dining area. He remodeled the kitchen and other parts of the house, and didn't find it. One day, months later, he called and told me I'd never believe what he'd found. He came home from work, and right in the middle of the kitchen floor was my zippo. It had spots of heavy corrosion on it like you'd see on a car battery or something. He mailed it back to me, I cleaned it up, and then I bought a new lighter and put that one away.
My wife and I stayed overnight in the home of my uncle's deceased mother-in-law. My wife (who likes to glance at the time when she wakes up in the middle of the night) woke me up in the middle of the night to ask why the digital alarm clock previously on the nightstand was tucked securely under my pillow (and under my head). We took the hint and were out in 10 minutes.
