The Middle of Nowhere akin to the Point of No Return.
One example of Nowhere: Let's say you're driving along the freeway and your car breaks down. Do you walk back to the last exit, or do you walk to the next exit? If the exits aren't within sight and you don't remember how far the exits are away, or whether you will find help at either exit, then you are in the Middle of Nowhere.
Another example: If you die without being certian about where your soul will end up, You will be in the Middle of Nowhere, until your soul reaches it's destination. I suppose if you end up being a ghost, then you will be stuck in the Middle of Nowhere.
I think I saw a documentary once, about Nowhere. It was on the Twilight Zone.
