Everybody has a secret world inside of them. I mean everybody. All of the people in the whole world, I mean everybody — no matter how dull and boring they are on the outside. Inside them they've all got unimaginable, magnificent, wonderful, stupid, amazing worlds... Not just one world. Hundreds of them. Thousands, maybe.
Neil Gaiman: The Sandman Vol.5
Sometimes, when you look around. Everything seems still and clam on the surface. Then you detect a little disturbance. And you know for sure there lies some other secret world.
Peter Gabriel: Secret World 1994
Something that is kept or meant to be kept unknown or unseen by others.
Something that is a mystery.
A valid but not commonly known or recognized method of achieving or maintaining something.
One's life and activities. A particular group of living things.
All that relates to a particular sphere of activity.
There is a continual temptation to narrow life. From the things we sign up to, commit resources to and give credence to. But the world / worlds behind our world shouts at us to drop a pebble in the pond and disturb our line of sight.
The rewrite is going well... so is the secret world.
