What characteristic is most associated with surrealist artworks?

Surrealist artworks are primarily characterized by their depiction of dream-like and fantastical elements. This movement, which emerged in the early 20th century, places a strong emphasis on exploring the unconscious mind, dreams, and irrational juxtapositions. Surrealists sought to challenge the viewer's perceptions of reality by incorporating bizarre and unexpected imagery that often reflects dream scenarios, thus creating a sense of disorientation and inviting deeper psychological exploration.

In this context, while strict adherence to realistic forms, the use of vibrant primary colors only, and the focus on social and political themes may appear in various artistic movements or styles, they do not capture the distinctive essence of surrealism. The surrealist emphasis on the irrational and the imaginative underlines its foundational principles, making the portrayal of the fantastical the most defining characteristic.
