If I remember everything that happened up to the point of death, it truly depends on the situation of my death. Would I respawn if I lived till 108 and my organs just decided to stop and I died like that, I'd say, "Am I in heaven?" Look around and see normal people acting normally, chuckle to my self and blurt out, "Hah! this looks like Hell! I knew Earth was actually Hell." being shot it would simply be, "AAAAAAAAAAAAHHHH" look around a bit, "AAaaaaaaahhh....? The FUCK?" If it's in a game it's usually, "Nice Shot."
