I am very sorry.
I had a similar dream experience.
I had a good older friend who was a kind of mentor to me.
I had moved to another state, but we got together for breakfast whenever I visited my home state.
Several years down the road, I learned that he was ill and dying.
Wasnt able to see him. He was too ill.
One night I dreamt of him.
I was trying to talk to him, but in the dream he just smiled at me and didn’t talk back.
I found out later that he had died.
His upcoming death had been on my mind, so maybe that presaged the dream.
Or maybe he was telling me he was gone.
I don’t know.
