My mom is 96. She's healthy, active and other than normal short-term memory lapses she's amazingly alert and lucid.. But three times in the last year she's mentioned seeing someone walking in the living room...always at night but at different times. If she closes her eyes and looks away, it disappears. She says she isn't frightened by it. I have never been in the room with her when this happens. It happened again tonight (early evening). I'm having her call her doctor tomorrow but wonder if anyone else has had this experience. She isn't taking any opiates, just the standard blood pressure, cholesterol stuff. I did some research online that says it could be dementia- or Parkinson's-related.
I'm glad it isn't bothering your mother, anyway. Did she say what she was doing when she saw this "person"? - I'm wondering if she'd just woken from a doze, or if the person appears in the same place, or resembles the same person, questions like that. I think it's probably jumping the gun to start worrying about dementia and Parkinson's Disease :)
If you use the search on this forum and look up hallucinations, you will find many posts. Some people have auditory hallucinations. Some find hallucinations comforting. Outside of a UTI test, I wouldn’t subject her to tests so long as she isn’t concerned.
My husband talked to deceased loved ones for about 2 weeks prior to his passing, so I know that they do come to visit,(even though I didn't see them) especially when someone is near death. To me it was comforting, knowing there were others with him as he transitioned from this life to the next.
