The book is divided into two sections: the 'Phases of the Moon' and the 'Mask,' each delving into a different perspective on the human experience and the universe.

The couple were a fan of the supernatural, and Plath (pictured) even wrote poems on the subject, including 'Ouija' and 'Dialogue over a Ouija Board.'
Poets and novelists Sylvia Plath and Ted Hughes (pictured) used a handmade Ouija board that consisted of an overturned glass as a planchette, and penned whatever a spirit named Pan told them.

'The Changing Light at Sandover' is a 560-page poem written by James Merrill with the reported help of a Ouija board.
'Jap Herron' was dictated to Emily Grant Hutchings and Lola V. Hays through a Ouija board. Twain's publisher, however, wasn't too happy about it and sued Hutchings in 1918, after which the book stopped being published.
The famed writer Mark Twain died in 1910, but, apparently, even in the afterlife he couldn't resist writing a few words. A few years after his death he supposedly dictated a book from beyond the grave.
The book contains a collection of uplifting messages about peace and love. Ouina's supposed life story was, however, a bit more tragic. Ouina's mother died when she was born and her father, the chief of the tribe, sacrificed her when she was a teenager.

'To Woman' was supposedly dictated to an American medium in Paris known as Mary McEvilly. The spirit who did so was called Meslom. 'To Woman' is a collection of writings about a woman's role in society.
Accordig to McEvilly, Meslom was a man, and perhaps that explains some of the sexist remarks in the book (i.e. men rule and women will never be able to make laws). Coincidently or not, the book emerged shortly before American women were granted the right to vote.
'A Wanderer in the Spirit Lands' was dictated to one A. Farnese by the spirit of an Italian man known as Franchezzo.

'My Tussle with the Devil, And Other Stories' was supposedly written by a writer known as O. Henry (born William Sydney Porter) eight years after his death.
The words themselves were written by American writer Thomas Cushman Buddington in the 19th century.
Medium Albert Houghton Pratt claimed to have written the collection of short stories by communicating with O. Henry (pictured) through a Ouija board.
This book was supposedly dictated by the departed Julian, Emperor of Rome. He shared his thoughts about the Roman Empire, how bad Emperor Constantine and his successors were for adopting Christianity, and how all this affected civilization over the following 1,500 years.
Maria Valtorta's work was considered heretical and added to the Church's Index Librorum Prohibitorum (Index of Forbidden Books). Still, in 1956 'The Poem of the Man-God' was published.

These spirits reportedly channeled their words through a number of people, who penned them and turned them into books. But who are these ghosts, and why did they reach out from beyond the grave? Click through this gallery to find out.
