Abstract: Robert Hass is an American Modernist poetand an expert intranslationand literary criticism as well.With the word flow，Hass opens up a path into the sub- consciousnessand consciously inducesa“hypnotic state” through the poetic rhythms. As a poet， Robert Hass uses hypnotic language to create a dream- like feeling. Meanwhile，the sober reality often makes the poet wake up the dream at the end of the poem. This paper analyzes the art of hypnosis of Hass’poetry in three aspects：1. Hass plants word flow into poetry and，with the flow of seasonal words，he breaks the boundaries of time and space to create a dream-like feeling in his poetry；2.“light” in Hass’poetry often softens the reality，purifies the memory，and helps to wake up nightmares；3. the essence of the hypnosis in his poetry is to soften the reality. Hass takes poetry as the container to carry the weight of reality，a weight that life can hardly bear.
