Lewis Carroll 
Rhyme? And Reason? 

This poem, also called ‚Phantasmagoria‘ is a narrative discussion written in seven cantos between a ghost (a Phantom) and a man named Tibbets. Carroll portrays the ghost as not so different from human beings: although ghosts may jibber and jangle their chains, they, like us, simply have a job to do and that job is to haunt. Just as in our society, in ghost society there is a hierarchy, and ghosts are answerable to the King (who must be addressed as ‚Your Royal Whiteness‘) if they disregard the ‚Maxims of Behaviour‘.
