10 Amazing Discoveries Made in Dreams

10. Anatomical Structure of a Fossil Fish

Swiss-born naturalist Louis Agassiz, considered a founding father of modern American science, is best known for his five-volume work, Recherches sur les poissons fossiles (Research on Fossil Fish), published in intervals from 1833 to 1843. As he was working on a particular type of fossil fish for the publication, Agassiz was stuck figuring out how to decipher the anatomical structure of the specimen as fossilized in a slab of stone. Fortunately, two nights in a row, he dreamt about the fish in perfect condition, but alas, shortly after awakening, he could not remember the details of the fish’s anatomy. Thus, on the third night, Agassiz left a pen and paper by his bedside and prayed he would have the dream again. As he had hoped, the dream did come, and while only half-awake, he drew the fish and went back to sleep. Shockingly, when the scientist fully awakened the following morning, he marveled at how accurately detailed his illustration was, thereby leading him to correctly decipher the stone slab.
