.. 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..

… is all that we see or seem
But a dream within a dream?

– A dream within a dream – Edgar Allan Poe, 1849. –
