Damn MOS.......Glad you're doing better

When I was 16 my Grandfather was on his death bed from cancer. He was shriveled up and couldn't lift himself out of bed towards the end. He slipped into a coma at the hospital.
I stood the night with him at the hospital along with my aunt. Around 3am he started talking and saying the craziest shit. mainly to his mother (which was dead). not long after he threw his hands up in the air like he was touching someone. He proceeded to lift himself into a upright position and continued to babble.
The thing that freaked me out the most is when he actually tried getting out of bed, that's when I ran out of his hospital room.
Thankfully my aunt was older and a nurse and knew what to do...........I went home around 7am when my grandmother and mom arrived for the day. They thought me and my aunt were losing it, but this was a 120lb man on his death bed and some how had the strength to try to get out of bed........Craziest thing I ever saw.
Oh and when I went home to shower and get a few hours sleep he passed at 9am. From what I was told it's a common thing, but it scared the shit out of me cause I was so young.
