The antonyms for the word "auto-biographies" include fictional tales, invented stories, and imaginary works. These are pieces of literature that describe events and characters that are not based on actual people, places, or experiences. Unlike auto-biographies, these works are created purely from the author's imagination and do not aim to relay factual information to the reader. Authors of such works can take creative liberties with their storytelling and explore themes and concepts that are not limited by reality. While auto-biographies serve to document and preserve personal histories and experiences, antonyms like fictional tales offer an escape from reality for readers to enjoy.
