Yep, my family has ghosts that like to pull pranks. It's happened far too many times for coincidence. My Uncle Charley seems to be the one we can identify, and he likes to 'hide' stuff you need.
For instance, you open the fridge to get out a stick of butter-the brand new package is gone. You haven't done anything else, you just walked in to get it. Start tearing the fridge apart, then go to the freezer in the basement and get a pound out. You walk back into the kitchen, and there's the pound of butter, sitting in the frying pan on top of the stove. No one else is in the house.
Yep, that was my step sisters introduction to Uncle Charley! When we can't find something, we always shout "Give it back uncle charley, the game's over" and leave the room. Come back and it's there!
We've never seen the ghosts, but they give themselves away by us smelling something-spaghetti sauce when no one's made it, coffee (for years I didn't own a coffee pot, but the smell was like it was brewing in the same room no matter what house I was in). It gives me comfort to know they're around.
