The final result does look like something out of Le Petit Prince. (Or so the tired artist thinks.) It was dear Johanna who suggested this, actually, and the tired artist said why not: The bed as some sort of oasis in a desert, sleep as our only refuge.
I haven't tried to make it the least bit realistic. One might photoshop something like this with live palm trees, a live actor and all. But that's not the kind of inner realism that I am interested in and would be sort of missing the whole point.
