I think I had hospital delirium once...lol
Had to stay there three days due to an ice storm...slept on a very uncomfortable roll-away bed in a storage room by the ER.
I saw a lot of confusion in older patients that had a TURP, that’s a transurethral-resection... a bit like a roto-rooting of the prostate...eeek
One of my bros had an episode of it after a long time on a ventilator, had to go along with it and humor him until it passed.
I don’t like to think of anybody messing with my plumbing - as you said, just the idea of it is Eeeekkk.
