This happens to me almost every night before falling asleep. I like to think I'm actually just composing what I'm hearing in my head! It almost always takes on a genre like bluegrass or orchestral or electronic. Very cool I enjoy self-made illusions!

Hypnagogic hallucinations are common. They're most intense for me when I'm falling asleep in a very quiet room. You don't need a source of noise for this.

This put the fear of God in me when I was a child. Sleep paralysis, which often joins it, feels quite frightening to a kid who doesn't know what's going on.

I have an air purifier next to my bed that creates a pretty loud white noise-like sound

Whenever I’m tired - which is practically every night these days (8 month old baby) - I end up hearing distant music from the air purifier

I find it rather soothing.
