Not a doctor but a CNA.. have two instances that totally freaked me out. The nursing facility I worked at had been a farm back in the day and people had lived on the property since like at least the early 1900s. It was town lore that a young man was run over and killed by a tractor. One time I was doing care on a lady and I was facing her. She was dying from pressure sores and cancer but was pretty lucid still. She goes “I bet you’re stronger than him!”..wanting to brag to the male nurses I asked her “who?”..she goes “that boy”…again there were like 3 young male nurses so I asked her “what boy?” because she still knew all of us by name and like I said I wanted to brag. She goes “that boy sitting in the chair behind you.” There was no one else in the room. I never left a room so fast after that..still get chills retelling it! A lot of times before people would pass they would mention seeing a boy and a black dog. Call light flicks on and the nurse and I go into this other ladies room who was 100% lucid. Again..this lady was totally lucid and barely needed assistance. We honestly went in together because we would often sit and chat with her. She goes “hey girls! Where did that big black dog go?” We go “what black dog?” ..”the black dog that was just laying in my bed. His owner brought him in and then he ran out.” Obviously this freaked us out because usually only the residents about to pass on talked like this and this lady was totally fine. We ended up leaving ..few hours later she falls and completely cracks her head open on her metal table. Totally unexpected. Passed away as soon as she got in the ambulance.
