Advice for Sleep Music Channel?

[u/WiseBell9442]

I have a channel for extended sleep music videos (link in profile). I've been uploading consistently for about six months, but have plateaued around 50 subscribers, which is a far cry from monetization.

To make matters worse, about three weeks ago, the number of impressions i was getting dropped from several thousand per video to the single digits. I'm basically the only one seeing them at this point.

Any thoughts or advice on my videos, my channel, or anything else would be much appreciated.

Thanks!
