I was my grandfather's caretaker.  He was dying of lung cancer, dementia, and heart issues.  Everyday for a year I'd tuck him into bed, say a prayer and say "hasta manana abuelo" (see you tomorrow grandpa) and he'd reply with "si Dios quiere"(if God wants it or God willing)

Well things took a turn for the worst, and he had a major stroke.  He was sent home on hospice.  He went downhill fast, lost 25lbs in 2 weeks, etc etc.  His last night, both he and I knew it was his last... I tucked him into bed and said "hasta manana abuelo". He just looked me in the eyes and shook his head no. I repeated myself and again he shook his head no. 

I spent the entire night knowing it was over, I kept passing by his room to see if I could witness his spirit or consciousness leave his body (yes I'm aware that it probably would never happen).  I walked into his room at 7am and he had passed sometime during the night.
