I’m pretty sure this is a thing, I sleep with a fan so my girlfriend does too, I often get up a lot in the middle of the night and she hardly wakes, and we even sleep with the TV on sometimes though i don’t like it. One time though I accidentally unplugged the fan and our white noise was gone and she shot straight up super startled like I had set off fireworks

For me it’s the cat scratching the carpet. I’m either just in time or too late.

I once slept through an earthquake, but the fan stopping will wake me up every time.

So it’s not just me…?

I feel this way about hearing my dog puke, lol
