This was posted today on Jim Emerson's Blog. In his words: "I can't explain it but I kinda like it." It sure helps if you've seen North by Northwest (1959) a few times. I don't know if it would help if you've experimented with psychedelics (and by the way, I'd strongly recommend against it). Mostly it helps if you've got a mind that you're welling to let step outside for a walk every now and again.
