This is both an atmospheric sound effect depicting some eerie, alien scene or world and also relaxing some sort of theta meditation mind trip. It transforms from hair raising and unnerving into something that calms and hypnotizes… But in my opinion it is very shocking in the beginning… and super soothing as the song progresses. .
I also imagine this as a journey inward for times when you may need to block out the chaos of your surroundings. A way of recapturing your breath in such a stimulated life environment.
Shock and soothe. Best wishes.
