Which excerpt from Samuel Taylor Coleridge's "Kubla Khan" most clearly indicates that he has forgotten much of the dream he relates? "Could I revive within me/Her symphony and song..." "...For he on honeydew hath fed,/And drunk the milk of paradise." "Weave a circle round him thrice,/And close your eyes with holy dread." "...And all should cry, beware! beware!/His flashing eyes, his floating hair!"
