When I was a kid I got a two deck cassette player and alarm clock combo. I used it as my alarm for about 16 years, and I still get a weird feeling if I hear that precise tone. It makes me feel a bit sleepy and disoriented for a split second. With the same clock I also started to wake up to the sound of the system powering up the speakers to play the torn before the tone sounded. It seems I’d slap the snooze button in my sleep so I had to get a new alarm.
