unseen, And with thee fade away into the forest dim" (11-12, 19-20). Harold Bloom states in his essay about Keats:
And yet, he welcomes this dangerous vertigo, for the next stanza of the poem seeks to prolong his condition by his wish for drunkenness, for 'a beaker full of the warm south.' The slackening intensity from poison to narcotic to wine is itself a return to an ordinary wakeful consciousness, a sense of the usual reality from which Keats here would 'fade away into the forest dim,' to join the nightingale in its invisibility and enclosed joy; to leave behind the world of mutability, where every increase in consciousness is an increase in sorrow. (376)
Bloom also agrees that Keats believes his life is over, and he has nothing to live for, yet he does have a small glimmer of hope down inside which comes out when he talks about nature, his desire for a taste of life, and escaping with the nightingale. Martha Hale Shackford also mentions this subject of desire:
Keats longed vehemently for some magic potion, a draught that would help the poetic imagination to escape from the brooding sorrows of the world of men, the world of mind and suffering. (283)
