 The nightingale described within the poem experiences a type of death but does not actually die . Instead , the <unk> is capable of living through its song , which is a fate that humans cannot expect . The poem ends with an acceptance that pleasure cannot last and that death is an inevitable part of life . In the poem , Keats imagines the loss of the physical world and sees himself dead — as a " sod " over which the nightingale sings . The contrast between the immortal nightingale and mortal man sitting in his garden , is made all the more acute by an effort of the imagination . The presence of weather is noticeable in the poem , as spring came early in 1819 , bringing <unk> all over the heath .
