I think really what its trying to say - after reading my previous comment - is that the person has stumbled upon the realization that reality is in the mind. Life is an "organic dream". Very solipsistic. Or at least, in all the person's musings and introspection they have suddenly realized reality is all in the mind. But the whole thing was like a secret.
But seeing as the song comes after In Death Is Death, i think it could be that now that the person has died, they have awoke from the "dream" that is life.
