Are there any books available that involve the causes and symptoms of sleep paralysis?
The library database Gale Virtual Reference Library has a number of reference books that have information on sleep paralysis, including causes and symptoms. These sources will give you brief overviews.
Encyclopedia of Sleep and Dreams: The Evolution, Function, Nature, and Mysteries of Slumber, Sleep Disorders Sourcebook, and The Gale Encyclopedia of the Unusual and Unexplained. Among others.
