What do you actually fall asleep to? (honest answers welcome)

We're a small team building nive, a sleep-sounds app, and we launch here on Oct 27. Before then I'd love real answers, not what you think you should do:

🌧️ Rain / nature sounds

🟤 Brown or white noise

🎧 Podcasts or YouTube

📺 TV in the background

🤫 Total silence

🌀 Something weird (tell us!)

And the follow-up: does the sound stopping ever wake you up? That's the one problem we built nive around (it fades out instead of cutting off), and I'm curious how common it really is.
