I don't think this has anything to do with God or even metaphysics, as evidenced by: "Oh to hell with superstition There's a stranger in the house I don't need no exorcism I need a key And the lock is inside out"

I think it's about trying and failing to understand consciousness, and specifically your own mind. The ghosts are part of that consciousness, but not the primary ones, evidenced by "a partition from the host." So I suppose he's trying to find himself, trying to find what he truly thinks and believes. Maybe the ghosts are humans' inherent biases and illogical thoughts that have to be weeded out before truly understanding something.
