So, question. Is there a sound that you find particularly soothing? Mine is the sound of tree frogs piping. I was in St. Lucia & they were SO LOUD I was convinced I would never sleep a wink. Instead, I slept great when I was there, & to this day the sound is super relaxing.
I love, love, love the sound of a crackling fireplace, fused with that of a thundering storm outside. It's rare to have it here, but if you like environmental sounds like this, https://asoftmurmur.com/ is such a great site for it
