Not losing my mind

Well, maybe I am. Buit at least the mystery of the ringing has been solved. It's not in my head after all! And it's not really a ringing either; there is a crew fixing the road oine block over and the backup signal beep from one of the trucks is just about the same pitch and interval as my [former] cell ring. So I guess my brain is turning a beep into a ring, but it's nice to know there's an actual external stimulus and I'm not just imagining that I'm wildly popular all of a sudden!
