he said on RoadRunner interview that he wrote this with automatic writing http://en.wikipedia.org/wiki/Automatic_writing and that he's not sure what it means

I've had moments like this. To help explain it, at least from my perspective, it's kind of just a state of mind you're in that does the writing from your subconscious. More specifically, if I'm feeling really emotional, but have been, say, awake far longer than I should have been and am running on a second-wind high, I'll start writing incessantly. One giant flow of idea fueled by my subconscious, processed by emotion as my conscious self takes the back seat and lets my natural mechanics do the work. It just comes out automatically as you seemingly zone out.
