Where are silioquies used?

Soliloquies are primarily used in drama and literature, particularly in plays, to express a character's inner thoughts and feelings directly to the audience. This device allows for a deeper understanding of a character's motivations and conflicts, often revealing their emotions or dilemmas when they are alone on stage. Notably used by playwrights like William Shakespeare, soliloquies enhance the narrative by providing insight into the character's psyche. They can also be found in poetry and prose, where a character reflects on their thoughts in a similar introspective manner.
