Though I'm sure it relates to something more mundane, I like to think this is the voice of a soul who misses being part of the connected totality of everything, misses how things were "at the start", before creation makes a soul human or even a soul a soul. Now it's stuck in a human body. It is the voice of a young simple soul - being a soul is simple - so it doesn't take a lot to confuse it, and the confusion and craziness of human life makes it sad, angry and frantic to escape.
