• After presenting an overview of scholarship on post-9/11 American poetry, my article focuses on a group of largely neglected post-9/11 poems, which deal with spectral consciousness and hallucinatory experiences. In exploring this issue, I have tried to establish a relationship between trauma-related intrusive memories and hallucination on the basis of information-processing model of post-traumatic stress disorder (PTSD), that clinical researchers also utilise. Moreover, the poems I have chosen not only challenge a number of traditional binaries like, ‘presence / absence’, ‘living /dead’, ‘synchronic / diachronic’ and so on, but also maintain in their most mature form a certain cognitive stability which lends a rich dimension to post-9/11 poetics. While examining spectral consciousness in such poems, my article also identifies interesting points of connection between postmodernism and them.
