I used to do the same: I would fall asleep to Rings of Saturn in high school. Same deal; more melodic than expected and also untreated AuDHD and bipolar made for a noisy brain.

Not napalm death, but for a while I went to sleep to the movie "Die hard."

Machine guns and explosions dont normally line up with lullaby's, but I'd watched it so much that I found it comforting. I expect my brain just learned to filter out the louder noises as I slept.
