Fuck no.
A couple years ago I heard about this guy who went into a coma for a few months I think and he said it was the most nightmarish experience of his life.
He was experiencing consciousness, but it was like he was trapped in a dream or another state of wakefulness in another dimension, but he was basically re-living the same scenario on repeat and it was terrifying and tortuous. He was being chased and torn apart by creatures/demons and then being respawned. In this state, he even experienced/saw his daughter being killed by being thrown into some sort of grinder and he said it felt so real and the screams and the fear felt so real that it literally traumatized him.
Just on that testimony alone I would never want to be in a coma, ever.
