Something you might want to try
I'm a very heavy sleeper. A lot of the time I don't even hear my alarm clock go off if it isn't right next to my pillow, on the bed next to me. If it's on the dresser or table next to the bed, no chance. I won't even hear it. So I always sleep with the clock on the bed next to me. One of the things I've noticed over the years is that any clock I buy, and it doesn't matter what type it is, doesn't keep proper time and it has a very short working life. Sometimes as little as two years.
The time goes out of whack, and eventually it stops working altogether. And I have to buy a new one. I've probably gone through 6 alarm clocks in the last 15 years or so. Now a malfunctioning clock that gains or loses time should do so at a constant rate, theoretically. It should gain or lose X seconds or minutes a day, every day. Mine don't do that. They work properly for weeks on end, then all of the sudden they gain 5 minutes, or 8 minutes or 10 minutes, it's never the same, in one night. Eventually over the period of 6 months or so I'm a half hour fast, and I finally adjust it back to the time on my computer or phone. A few weeks go by, the time is in perfect synch, then it goes out again. I've been doing this for years.
I have a theory. I think that when they come for us, a field of some kind is generated around us, that affects the function of electronics, if any are in range. Or something like that. They keep that field tight, just big enough to cover our bodies, + a little bit. They want you, not your wife sleeping next to you, or the dog over in the corner. Maybe 6 inches in any direction. Most people laying in bed have nothing closer than about 3 feet from them, except me, because of this problem I have hearing sounds while asleep. My clocks seem to fall inside that range. That's why the have this intermittent problem keeping correct time. On the nights they come for me, the clock goes out of whack. On the nights they don't the clock works properly.
If you suspect you may be getting abducted, try that. put the clock on the bed with you, close. Synch it up with the internet and just leave it there and check it's time now and again against what you synchronized it to. Mine is always fast when it happens. Real time is 10:00, my clock reads 10:07. I've never kept detailed records, but that's something you might want to think about. Keep a note book next to your bed and write down the results every day. If you find you're having intermittent problems with correct time, you might be being adducted at night. That's if I'm correct, and I don't know that I am. But it's something you might find interesting to fool, around with.
