A couple of weeks ago I was at the hospital because my dad had a clogged artery. One of the patients kept calling out 'Nurssssssseeeeeee' in this pained and labored tone. Me and my sister got pretty worried because he did this every few minutes for HOURS and hours. The nurses weren't doing anything and the guy sounded like he was in pain. One of the nurses eventually told us that the man's mind was going, it wouldn't have mattered if he had a nurse at his side at all times, he was just... absent.
On the second day the man was still calling out 'Nuuuuurrrsssseeeeeeee' every few minutes. Well, the tiny bathroom on that floor was right next to his room so when I went to take a leak I could still hear him except that this time, I swear to god, he didn't say 'Nurse,' he said 'Braaaaaaaiiiiiiiiiinnnnnnnnnsssssssss.'
