Keep the song title in mind.
Everyone is asking themselves these questions now and then. Wayne does it himself and at the same time he realizes that the questions are lame (he doesn't even finish his question about the birds). So he's calling it a placebo headwound: a moment where these questions pop up in mind, although you know there's never an answer and it doesn't really matter anyway.
I like to think that its alright to have questions like this sometimes, but only when you realize it's just a placebo headwound.
This is only a interpretation off course...
