English mathematician Charles Dodgson suffered from migraines and was intrigued by the stages of the terrifying headaches that would haunt him at the most inopportune moments. His literary work, which he authored under the pen name Lewis Carroll, features a structure that seems to have been inspired by migraine stages. Such is the case of Alice in Wonderland and Through the Looking Glass, two classics that Dodgson may have written during a postdrome stage.
