A Doorway to Narnia?

Last year we finally got a wall put up around the house where I live. A door was put into the back wall.

I was confused at first because there is nothing behind my house. There is no road or pathway. There is just undergrowth and a few trees. Why put a door there?

But then I realized that this door could lead to Narnia (like in The Silver Chair).

Why not?

Anytime I venture beyond this door I could meet Aslan! Alas, so far I've only met Zevi, my own dog.

But maybe tomorrow will be different.
