When we were younger, I am guessing around 13, my aunt and uncle dragged my sister, then 11, and I to my uncle's family farm over a school holiday. My cousin and I were born 13 days apart, partners in crime our entire lives. My uncle's father had died a few years prior to this, and his mother was living there alone. She is 94 years old now and still going strong. At that point she was well into her 70's, she still cooked large meals, killed wayward snakes that slipped into her house, churned her own butter and even made her own soap.
Whilst visiting on the farm, we "invented" a game where we would all walk in a straight line (at this point more family had arrived and we were 6 kids: 3 boys and 3 girls) and as you walk, everyone slips away from the leader and goes to hide. Once the leader realizes they are alone, he/she then starts searching for the others. Basically turning into a game of hide and seek then. First one found is the leader for the next round. My cousin, being the mastermind behind this game, dubbed it "Follow the weasel". It was the most fun to be had on a farm, being city kids, when we weren't climbing trees and reading books (at that point in my life I was addicted to Dean Koontz books, my favorite being Watchers).
One morning my cousin was in the bathroom and the next moment she started screaming and she came bolting down the passageway. She said she had been bent over the basin, brushing her teeth, and she looked at the space between her feet, and there she saw her grandfather's shoes. She whirled around and nothing was there. She freaked out and bolted down the passage. Her gran told her that she frequently saw a shadow pass doorways when she was alone and she believed it really was her grandfather. My cousin kept seeing the shoes every so often the week we were there, but I never even felt anything in that house. I'm guessing he was just checking on his family.
