<human>:  What is the difference between surrealism and Dadaism?
<bot>: The main difference between surrealism and Dadaism is that surrealism emphasizes the expression of imaginative dreams, as opposed to Dadaism which pushes for a rejection of traditional cultural values and aesthetics. Whereas surrealism focuses on unconscious expression of the inner self, Dadaism tends to explore the meaning of irrational thought and experience. Both surrealism and Dadaism have been seen as early predecessors of the art movement known as postmodernism.
