are you sure? it might be, but the other songs in the soundtrack that are based on aphex twin songs sound almost exactly like the actual song, while this only superficially sounds like Desert Wind
the song that plays when you're in a deep dark forest all alone, completely colourblind so you only see in B&W, and the trees seem to stretch for miles into the darkness... and they are walking
This sounds like "Now the night is over and the dawn is about to break" and "No one knows when shadowy memories haunt them to this day" by The Caretaker
