But a dream

I love this poem. People see it differently. How I interpret it:   First he talks about being in a dream. I see life as a dream. Not that of my own but of another. Could we be but a dream.  The sand is our time, we should hold on to it tight and for as long as we can for it won't always be there. Enjoy it and embrace it.
I like this poem because life has always been a puzzle to me. How we came to be and how we will end. Why do we rush so much to get no where?  The only destiny I believe is that one day, that sand will run out. We can hold tighter or let loose, it's our choice. 

A Dream Within a Dream
by Edgar Allan Poe
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?
