A fictionalized memoir is a blend of real-life experiences and fictional elements. It's not strictly factual like a traditional memoir. The author might tweak events or add fictional characters for a more engaging story.
Night is actually a memoir. The author recounts real events and feelings from a specific period of their life, which is a key characteristic of a memoir.
Memoirs are typically nonfiction. They provide an account of someone's life or specific experiences as they actually happened. Authors share their true stories and perspectives without fictional elements.
