<human>:  How did the art movement ‘surrealism’ start?
<bot>: The movement started in the 1920s, and was inspired by the writings of Sigmund Freud. The surrealists believed that the world is not as rational and logical as we might think, and that our minds can create their own reality. The movement was especially popular in the 1930s, and many of the artists who were part of the movement had a profound influence on modern art.
