The wildness of imagination.
There is a limit to the credibility you can put into a story. Unless you are writing absurdia, your reader expects, especially if they are paying, some modicum of logic in your tale.
On the other hand, if you're doing it for yourself or putting it out for free, you can let your imagination run wild.
Tonight I came across a writer with more imagination than you could shake a bag of spanners at.
Take a look, and just soak up the madness. It's good for you. In a wilted pocket-watch kind of way.
