A couple months ago, we wrote about a YouTube user named Crysknife007 who creates aural sleep aids for the most dedicated film geeks. His specialty is long-form audio YouTube clips (sometimes up to 12 hours in length) that loop a snippet of sound from classic sci-fi movies creating a blizzard of white noise to lose yourself in. In September, we were fixating on the metallic thrum of the Nostromo’s medical bay from Alien.

But perhaps that selection was a little too mechanical for you? Maybe you want something closer to nature? In that case, you should check out his latest clip above, a 12-hour loop of a sandworm on the move from 1984’s Dune that’s topped off with a modified Shai-Hulud prayer, “Bless the Maker and His ambient sound./ Bless the rushing sand and deep bass of Him.”
