Analysis of A Dream Within A Dream

Take this kiss upon the brow!
          And, in parting from you now,
          Thus much let me avow-
          You are not wrong, who deem
          That my days have been a dream;
          Yet if hope has flown away
          In a night, or in a day,
          In a vision, or in none,
          Is it therefore the less gone?
          All that we see or seem
          Is but a dream within a dream.

I stand amid the roar
          Of a surf-tormented shore,
          And I hold within my hand
          Grains of the golden sand-
          How few! yet how they creep
          Through my fingers to the deep,
          While I weep- while I weep!
          O God! can I not grasp
          Them with a tighter clasp?
          O God! can I not save
          One from the pitiless wave?
          Is all that we see or seem
          But a dream within a dream?
