Tales of clocks and time jar loose another memory of years gone by. When I was a youngster, I built my first LED clock. It had 6 digits that were .6" tall. It would show the time - down to the seconds.
I learned a lot from building it, and in those days, had a transistor radio that I used to play music on local (and some - not so local) AM radio stations. Well, when set near the LED clock, it would pick up the clock generated noise. It almost had a tune or rhythm to it.
Anyway, I got pretty good at estimating the elapsed seconds - a game I used to play.
I used this LED clock to wake me up in the mornings, and for some reason, I got to where I would 'snap' awake and do a mental countdown... 10, 9, 8, 7, 6, 5, 4, 3, 2, 1,... *BEEP* *BEEP* *BEEP* would go my clock - on cue.
Now... keep in mind that I wound not open my eyes to look at the alarm clock - I would just wake up 10 seconds prior to it going off.
I can't do that 'trick' anymore... but I used to.

Computers also make 'noise' when you place an AM radio near them, and waaaay back in the day, when I was using a new PCB Layout program that ran on the IBM AT (6 MHz), I got good at predicting where the program was in the 'routing' phase of the program, just by listening to the 'tune' of the noise generated. (They didn't have much in the way of 'status' messages that told you what was going on - so you just waited.)
Okay... these aren't 'supernatural'... but they are 'cool' experiences.
