Final answer:
Non-realism in drama often involves using abstract, surreal, or fantastical elements such as symbolic characters, dream sequences, non-linear narratives, and the use of metaphor and allegory.
Step-by-step explanation:
Dramatic devices that are considered hallmarks of non-realism often include elements that break from the conventions of realistic theatre, where everyday life and typical experiences are depicted in a straightforward fashion. Non-realism instead embraces more abstract, surreal, or fantastical elements that go beyond the ordinary. Common non-realistic devices include symbolic characters, dream sequences, non-linear narratives, and the use of metaphor and allegory to represent reality in a more subjective and less literal way. These techniques create a layer of meaning that is deeper than the literal events on stage. For example, in non-realist theatre, a character may have exaggerated features or unexpected reactions to emphasize a theme or idea, scenery and props might be deliberately unrealistic to highlight symbolism or theme, and lighting and sound are used in exaggerated ways to create mood or indicate a break from reality.
