A flashback is a storytelling technique that takes the reader or viewer back to a previous event in a character's life. This moment can reveal important background information, emotions, or motivations that help us understand the character better. For example, a character might suddenly remember a childhood friend or a significant event that shaped who they are today. In movies and books, flashbacks are often shown through visual scenes or descriptive passages. They can be triggered by something in the present, like a smell or a sound, reminding the character of a past experience. This technique adds depth to the story and helps create a richer narrative.
