Yes, I’m convinced both our parents could hear us and respond even when unconscious. I think it gave them great comfort to hear us saying positive and happy things.

H’s buddy’s wife had a progressive condition that trapped her in a body that she became unable to move or communicate and left her bedbound for 5 years. Her poor devoted H visited every day but it was causing him to be severely depressed. One day, she was perspiring profusely and the recommended treatment ended up giving her 24 hours of being able to speak and move. She told her H she wanted to go home and be able to die in her bed and bedroom. He made it happen, though it took some work in his part.
