L. Ron Hubbard 
Slaves of Sleep & the Masters of Sleep [PDF ebook] 

Jan Palmer wakes from a deep sleep, into a living nightmare that seems to be a parallel universe of evil Jinn, deadly secrets and beautiful but dangerous dancing girls. While trying to figure out the meaning of his dreams, he finds humankind’s fate resting in his hands. If you have ever suffered from sleepless nights or insomnia, this is a tale that might just open your eyes. Slaves of Sleep is an L. Ron Hubbard tale of parallel universes-one of the first in modern fantasy writing. Cursed with "eternal wakefulness" by an evil Jinn, never-ending nightmares and imprisoned for a crime he didn’t commit, Jan Palmer is living hell in two worlds-or is this just lucid dreaming? On Earth, he is a prisoner of his own insecurities, and in the land of the Jinn, he is "Tiger, " the swashbuckling rogue-but in both, he faces death at every turn. Unless he can discover the meaning of his dreams, before it’s too late."I stayed up all night finishing it. The yarn scintillated." -Ray Bradbury
