In 1811 Joseph Smith, Sr. had a dream that was so vivid he shared it with his family. His wife, Lucy Mack Smith, recorded the dream in 1845 and published it in her 1853 book, Biographical Sketches of Joseph Smith The Prophet and His Progenitors For Generations.
The remarkable thing about this dream is how similar it is to a dream the Book of Mormon prophet Lehi had, which of course is recorded in 1 Nephi 8.
