Saw the same kind of thing when my father was passing away. He was on medication that was dealing with seizures.
He’d often have conversations with...someone. i started to listen in since i was taking care of him at the time. i was in the military decades after he was, but some things and terms don’t change.
He was having conversations with friends that never made it off Omaha Beach on June 6, 1944. My father went in with the first wave, got wounded twice that day, but not serious enough to evac.
My mother would complain about it, until i told her to leave him alone, and why she should leave him alone.
He died new years day in 2004. Just never woke up that day.
A few days before he passed on, he and i had a talk about the war. It was the first he’d ever spoken of it. Every day after D-day was gravy to him. When his health deteriorated, it was not pretty. He was hooked to an oxygen tank, pissing into a bottle, using a walker, sleeping in a chair, and his social life was going out to sit on the porch.
He wanted to die. My brother later told me that he was “cheeking” his medications so that would happen faster.
i don’t know that i blame him, and i don’t know if i would do the same thing or not...
I would not bother folks seeing dead people. Tell them it’s a vision of Heaven. Theologically possible and does no harm.
