Which YouTuber's voice can lull you to sleep?

I’ve exhausted things I can sleep to on Netflix, and it’s literally impossible to sleep to things on Prime (so I barely watch anything there; it’s not worth falling asleep to something I like, since I might be punished for it), so I’ve started putting on YouTube in the evenings since it won’t wake me with silence at 4am.

I’ve a few voices I love listening to, but I’d like even more.

Which YouTubers do you recommend who:

1. Have smooth, hypnotic voices,

2. have content that won’t give me uncomfortable dreams (I’m a very visual, realistic, and impressionable dreamer), and

3. have channels I’ll want to listen to when awake? (eta I like sciences and news mostly, a bit of fiction (scifi, horror, nf), gaming, other nerdy things, but never romance, pop culture , or reality tv).

I kinda need all 3.
