When I was Idk 5 or 6 maybe, my parents, my younger brother, and I lived in some rooms my parents were renting from some old couple who also lived in the house. They had a son with developmental disabilities who had passed away in the house sometime before we moved in. A rocking chair would move a tiny bit, plates fell out of the cabinets & smashed on the floor, and one of my brother’s toy cars used to move across the hallway even though nobody touched/pushed it. The older couple would say these things happened because of their son who had passed away and were happy about it.
