There is a place where imagination exists outside the mind.
I wrote a series of stories based around a war with a parallel universe called the Libariverse from whence all stories come and where all fictional characters are alive.
The basis of the first story is a writer who concocts a story about an author who discovers our real universe and attacks it, only to find his room invaded by a Dodo riding mad Hatter who beats him to death with a teapot.
