I can definitely relate to her experience -- just as I was waking up in the recovery room, I had a dream that I was a 4 year old again yelling at my father to stop the car we were in because I needed to go pee so badly, and I was being told that I could not need to pee that terribly. The lighting in my recovery room was so dim (to me) that I had a moment of worry it might be the morgue.
I am glad she is OK and seemingly happy here, but yeah, the pain meds are meant to confuse you about whether you hurt or not, and they tend to go overboard into other ways of confusion.
