I’m not a medical worker, but my grandfather died when he was 54 years old of a sudden heart attack. According to my mom, I came up to her that night and told her I had seen grandpa by the window wave at me and fly off into the sky. I had no clue and no way of knowing he was dead, and I had never made up stories like this before or after. We think it might’ve been his final goodbye, so to speak. 

I still cry whenever someone mentions him to me. We shared a real bond.
