Where Do We Go When We Sleep

This is for a competition to create artwork for the musician Billie Eilish's album "Where Do We Go When We Sleep".
As I listened to the album, I got a very subtle, kinda eery feeling like there is a lot under the surface that isn't seen. Tried to capture that feeling with this image.
