What is the definition of drama stimulus?

Drama stimulus is any event, object, or situation that triggers a dramatic conflict or action in a play or dramatic work. It is the initial impulse that sets the plot into motion and drives the characters to react and interact with each other. The drama stimulus can be internal, such as a character's inner turmoil or desire, or external, such as a physical event or obstacle. It is what creates the tension and suspense that is essential to any dramatic narrative.
