"The Love Song of J. Alfred Prufrock" by T.S. Eliot is a classic example of stream of consciousness in poetry. The entire poem is presented as a series of fragmented thoughts and images, reflecting the inner world of the speaker, J. Alfred Prufrock.
One example of stream of consciousness in the poem can be seen in the opening lines:
"Let us go then, you and I, When the evening is spread out against the sky Like a patient etherized upon a table; Let us go, through certain half-deserted streets, The muttering retreats Of restless nights in one-night cheap hotels And sawdust restaurants with oyster-shells: Streets that follow like a tedious argument Of insidious intent"
Here, the speaker's thoughts move from a suggestion to go somewhere, to a vivid description of the evening sky, and then to a somewhat disturbing image of a patient etherized on a table. The speaker's thoughts then shift to a description of the streets they will be walking through, with specific details such as the "sawdust restaurants with oyster-shells." The poem continues in this manner, with the speaker's thoughts and images flowing in a seemingly random and unstructured manner.
