While my mother was in CCU, she did maintain a sense of humor. If nothing else, it amused the rest of us.
After she was stabilized, moved into her room, and we could see her, I knew she was OK, when she looked up at me and said, "If I thought breaking my hip would bring all this on, I would just have committed hari kari and gotten it over with."
One afternoon, I returned to her room and asked, "Which doctors have you seen since I left?" Her response was "Like I would know who was in here." This was a valid point given we seemed to add at least one specialist to her team every day. After being poked and prodded for several days, by Monday she would simply address any new medical personnel who entered the room with, "Who are you? Have I met you before? Are you going to stick me?"
At one point I told her one of the family members she had not seen in a long time was on her way up to see her. "Well if she is coming to see me. That surely means I am going to die." When the family member walked in the room, her words were, "Oh God, I'm doomed."
As the week progressed and she grew more weary, she told me, "I don't want to see anyone, just tell them I'm too sick, tell them I died."
