Very good!
I did as you described and headphoned myself and turned down the lights. Initially it made me think of a crystal cave in the middle of the oceanic abyss (probably due to the resonant, slightly high-pitched sounds you employed) filled with strange life. Towards the middle it switched to a completely deserted and desertified planet in some far-away galaxy. Then at the end it started getting slightly eerie and I thought of some poor comatose soul in a hospital room, unable to wake up.
3 distinct scenarios in one musical piece! Very good man.
