what is supernatural in S T Coleridge's poetry?

Are you asking about his general use of the supernatural or something more specific....... possibly Rime of the Ancient Mariner?

Coleridge emphasized the supernatural and the power of the natural world in his works. "Kubla Khan" describes the building of a "stately pleasure dome" that itself is formed by the bizarre natural (supernatural?) phenomena of icy caves under a sunlit sky. "Rime of the Ancient Mariner" combines elements of the natural world (such as the Albatross) with the supernatural (such as the strange sea creatures) to describe the connection between the seen and unseen worlds, as well as human beings' interconnection with both. Nature is celebrated outright in other poems, such as Coleridge's "Sonnet: To the River Otter," and forms the basis of thoughtful meditation in "Frost at Midnight."
