dreaming of tango

I'm working in a hospital in Buenos Aires. Everytime there is a ward round we go to the intensive care unit to check how our patients are doing. On the way out, in a bay almost hidden by a corridor I always listen to fuzzy sounds of tango. The other day I ventured to see who was there. I saw a man, in his 70s, intubated and sound asleep, a small radio tuned into 92.5FM pouring tango and nothing else. I asked the nurse who this man was. She told me that he had been in coma for some time now and that his family had brought him the little radio so that he would be listening tango while he was sleeping. They said that if he was listening to tango, he would probably be dancing all the time in his dreams.
