This is a real, normal thing?? I can hear snippets of music, usually orchestral or opera, as vividly as if they were actually playing, but all I'm listening to is the white noise of a fan, and I'm just remembering them from before. When I was young, it was often a radio announcer because we listened to the radio in the car a lot. I always thought this was very bizarre and was not supposed to happen to normal people.
