I recommend the Deep Sleep playlist on Spotify! A very soothing experience which makes you drift away to a world full of beautiful dreams and has you wake up feeling refreshed and rejuvenated like you've never been before.

Not talking about dust, but actual decent albums which are good to fall asleep to.
Nick Drake - Pink Moon for some quiet, semi-folky tunes with top-notch finger picking and soothing vocals.
Jan Jelenik - Loop-Finding-Jazz-Records for some glitchy idm type stuff where the drums are just pops and clicks and the instruments are warm layers of chords and noise.
Music For Nine Post Cards - Hiroshi Yoshimura for some slow, minimal, but totally gorgeous and soulful ambient music w/o any drums or vocals. Feels like it can soothe the soul.
