An internal monologue is the process of thinking in words, where a person reflects on their thoughts, feelings, and experiences. This self-talk can help individuals make decisions, solve problems, or understand their emotions better. It often occurs in everyday situations, such as when someone is contemplating a choice or processing an event. This mental dialogue can vary in tone and content, ranging from positive affirmations to critical self-reflection. Internal monologues are common in literature, where characters like Hamlet or Holden Caulfield express their inner thoughts, allowing readers to connect with their struggles and motivations.
