if you like to listen to music when you sleep, my dad used to always put on Mendelssohn‘s a midsummer nights dream to put me to bed when I was young, and it still helps me go to sleep occasionally (even though it starts off loud and fast). I also liked Nick Drake’s Pink Moon for this purpose. Ive found that having a routine and playing the same thing every night helped signal my brain to sleep (though now that I work long hours just the sound of a fan works great).
