Dream sequences are scenes in films, literature, or other media that depict a character's dreams or subconscious thoughts. These sequences often feature surreal imagery, unusual events, and a departure from reality, allowing for creative storytelling and exploration of a character's inner feelings or conflicts. In storytelling, dream sequences can serve various purposes, such as foreshadowing future events, revealing hidden desires, or providing insight into a character's psyche. They can also create a sense of mystery or tension, engaging the audience by blurring the lines between reality and imagination, often involving elements like symbolism and metaphor.
