I don't know if this story exactly qualifies and don't know if they will accept it but figured it's a cute story on how some things can be other than what they seem to be.
My grandmother and I had been experiencing some rather unusual activity in the apartment. The usual kinds of things you hear about from those who have a poltergeist in the house. Lights turning on and off with no one in the room, things taken from one place and left in another, the thermostat going up and down when no one is in the room that kind of thing.
I wear a pair of slip on shoes when I go outside for a smoke and take them off and leave them by the back door when I come in and grandma or I will find the shoes in two different places in the front room or dining room.
This went on for a couple of months before we could find an explanation for it. We had pretty well decided it had to be a ghost. We were wrong.
I was standing in the kitchen doorway talking to grandma when we heard a scratching noise behind me and the kitchen light turned off we looked but could see nothing but the cat sitting there staring at us. Then as we both watched, the cat jumped up the wall and turned the light back on. Later that night my grandma caught the cat dragging one of my shoes out of the kitchen.
I later caught the cat jumping at the thermostat and changing the temperature, its one of the older styles the round ones with a dial you turn not a newer digital one. We also found a stash of things when we moved some of the furniture in my room around, things like loose keys, earrings, straws, paper wrappers coins, anything the cat could pickup and carry off.
Grandpa then caught the cat fishing in his computer desk drawer and stealing pencils, pens and a couple rubber bands.
