My grandfather was already old and sickly, he would often be hospitalized and come home for only a few day just to go back to the hostpital, things got worse when his wife (my grandmother) passed away so not only was he ill, he was also depressed so one day while Me and my cousins were with him in his bedroom/office he just suddenly collapsed and fell, his eyes were still open and was we can tell he was still conscious so we immediatly had to call an ambulance. When they loaded him into the ambulance I was just staring right at him but his eyes just rolled back into his head and his feet became limp and the ambulance doors just closed right after. He was pronounced DOA at the hospital and till this day I still feel haunted seeing the exact moment he lost consciousness
