How is the poem, Late and Deep, an example of Surrealism?

Several aspects of "Late and Deep" show surrealistic influences. Most prominent is the perplexing and dreamlike "we flourish the white hair of time." The German verb means "to brandish" in English. The image is nightmarish, as human hair functions as an object, a totem, or a flag. Similarly, the stair in the water, birds to a shoe, and the white meal "You grind in the mills of death" all have a surrealistic and nightmarish quality.
