How do these final lines from "kubla khan" by samuel taylor coleridge affect the overall tone of the poem?

his flashing eyes, his floating hair!
weave a circle round him thrice,
and close your eyes with holy dread
for he on honey-dew hath fed,
and drunk the milk of paradise.

the last lines bring the poem to a (sacred, climatic exotic, historical, dreamlike, madness) close. flashing eyes evoke the image of passionate creativity. by talking about "holy dread," coleridge suggests that creation is both (sacred, climatic exotic, historical, dreamlike, madness) and demonic.
