Dream-like has always been the first way to describe Magritte's work, and maybe it remains the best. He's certainly among the oldest of my old favourites, and if the jolt of his art has been dulled a bit by familiarity, time and changes in my own sensibilities, it still holds plenty of charge regardless.
"La condition humaine", 1933
"L'empire des lumières", 1954
