I watched my father slowly die, he talked to angels. I could hear his side of the conversation. He kept reaching up and asking for them to hurry. He did die and return twice, each time he told us about all the people he met, and told him it wasn't his time, go back. Dad was terminal for years, in and out of hospitals and ER's. I get my bull headed ways from him.
Like in your case everyone blamed hallucinations, at least when others could hear. Most told me they believed after years of seeing the same things, they would never admit it to each other. I had an EMT tell me she never saved anyone that smiled and reached up, she could only save people that looked scared and screamed in fear. She was 100% convinced dying people could see their next home.
Thanks for sharing, I returned the favor because I do care, and I think people need to hear about what comes next.
