Taking Hubert Hermans' the Dialogical Self Theory (DST) as a framework, this paper attempts to find out psychological clues to the ambiguity of “the Rime of the Ancient Mariner,". With Coleridge's known interest in psychology in mind, especially his refutation of the unity of the self in favor of multiplicity of the self, this paper tends to read the poem as a dialogical-self narrative reflecting all the possible I-positions needed to form a creative and psychologically normal self of the typical romantic poet. The poem with its narrative structure, narrative voices, gothic scenes and religious hints, reflects the dialogical I-positions proposed by the DST. As a typical dynamic structure of the human self, the dialogical "self" narrated in the "Rime" struggles to enhance its poetic sensitivity and romanticism that falls between its own uncertainties and a surrounding unrecognizing society. Conflicts, contradictions and sometimes integrations are all possible interactions that happen between these different I-positions in a self that extends between its internal I-positions and its external I-positions to fulfill the balance needed between centering and decentering positions in order to attain unity and, at the same time, sense of creativity.
