Many years ago I had a LG CRT that often would turn off in the exact moment I entered the bedroom. The monitor was configured to go to sleep after 20 or so minutes of inactivity, so it was supposed to turn off on its own. And I always assumed it was a case of only noticing it when it did happen (like when you buy a car and suddenly start seeing the same model everywhere)... But it always seemed uncannily frequent... Now I wonder if I might have somehow disturbed the electric field each time
