I'm having a wee chuckle here - and not to take anything away from your stories ( read your link and it is mind-blowing) but this morning I was dreaming about my student cleaning a wound and then using the same swab to clean another wound in a different place on the patient. I woke in a panic that they would even contemplate doing that - and then realised I was dreaming.
Our subconscious works in intriguing ways. I often have very vivid dreams and have started trying to write them down to make more sense of them. My one this morning made perfect sense since I had yelped at a student the day before for screwing up!
