A few years ago I was in a bad motorcycle accident that left me comatose with a broken jaw and six missing teeth, among a slew of other injuries. What you described felt exactly like waking up from my coma. That floating feeling, and being hyperaware of all the sensations around you but not reacting to any of them. There’s a peaceful numbness among all the calamity. I learned then that opioids don’t get rid of the pain, it just makes you be okay with the pain being there, at least in my experience. Reading this was a bit triggering but I weirdly enjoyed it. It’s an extremely unique experience that you worded way better than I could have.
