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.
