Akin to the infinite patterns of fractals found in natural creativity, networks of knowledge feed themselves, resulting in repetitive branching. In recursive reality, it's impossible to know which is the base reality. This leads to questions about the fabric of space and time, e.g. the simulation hypothesis.
See A dream within a dream by Edgar Allan Poe, first published in 1849:
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?
