You definitely went for a simpler solution!

And thanks for sharing that comment, I can second your two observations

For multiple months, I thought I’m waking up at night because I need to go to the bathroom so often (even checked for insulin resistance but markers were perfect). Interestingly enough, most of the times (not always) there are one or multiple louder sounds just before I wake up to go to the bathroom. Zero memory or conscious perception of the noise, still woke up and feeling like I need to go to the bathroom

One time there was construction/renovation going on one floor below mine. I'm talking sledgehammers, jackhammers, the whole shebang.

For some reason, I've never slept better. Every little noise generally wakes me up (like someone walking in the same room) but the demolition noises kind of numbed me to all audio, apparently.

I also somehow sleep better when I leave a window open, and get some morning sun and noise? Though in that case, loud motorcycles revving will probably wake me up, but random people talking/shouting is fine.
