Flaming Lips - Placebo Headwound lyrics

Where does outer space end It's sort of hard to imagine Is it real? Is it nothing, nothing? Cause it's not so clear anymore to me Why do birds always fly south When sometimes its warm in yer head wound Is that nothing, nothing? Cause its not so clear anymore to me And if God hears all my questions Well how come there's never an answer? Is it nothing, nothing?
