answer:I was just remembering one other possible experience. After my father in law passed away my husband and I drove up north and stayed with my mother in law. We slept in what we thought of as the guest room, which had twin beds, but actually my father in law slept in there a lot due to excruciating pain from pancreatic cancer and he didn’t wish to awaken his wife with his loud moaning and groaning. I was asleep in his bed. After I’d say about half an hour I felt “somebody” gently pinch my big toe. He was an affectionate man , a fatherly type, and it seemed right away that would be something he’d think to do. I only knew him a few years and only saw him once a year. FWIW
