A singer apologized, closed his eyes, dropped his head and died onstage
I've heard a few stories where a person seemed to suddenly acknowledge that they were about to die. Granted, my grandmother repeatedly claimed she was going to die that night and the one time it was true the family lore became that she somehow knew. But to stop what you're doing like that, I wonder what it is they're actually feeling in the moment. Did he know he was going to die? Did he just feel dizzy? What do people feel in these moments just before death?
