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.
Three main thoughts stand out in the ode. The second main thought and the main theme of the poem is Keats' wish that he might die and be rid of life altogether, providing he coulddie as easily and painlessly as he could fall asleep. Hearing this the author doesn’t think that dying is going to be painful the author is hoping to make it easy as “falling asleep”
