By comparing himself to the figure of Lazarus, Prufrock is engaging in something of a life-death narrative. In his imaginary conversation with the woman he seems to be addressing the poem to, Prufrock imagines himself saying "I am Lazarus, come from the dead" where Lazarus lying dead in the tomb is like Prurock engaging in his self-made universe (the poem). Lazarus returns from the land of the dead to tell others of f his experiences just as Prufrock imagines himself coming out of his thoughts - which might be drug induced - to tell of his imaginings.
