How do you fall asleep?
Silence?
Noise?
What sends you to sleep?
I mostly need white noise. I lucked out in that at my current place, the ceiling fan makes a solid buzzing noise; but otherwise I usually fall asleep with the TV on (I make a custom setting with brightness turned all the way down) and I play 80's-90's horror movies (yeah I don't know, don't judge me).
I have some Youtubers I fall asleep to, like Areal Flood Advisory (she does some videos on strategy games, but her voice is just very soothing and ASMR). There are some Youtube channels that are nothing but dark screens with thunderstorm sounds, which has become a new favorite.
