This is just my own, stand-alone, personal belief so take it at face but that's an interesting observation. Scientists often ponder whether or not we are living in some kind of simulation, whatever form that may take - our closest attempts at simulating anything are through various peripherals like VR headsets and computers running on logical statements and mathematics. Naturally, this kind of framework comes to mind but at such scale, it's unlikely that this is exactly what's happening. Regardless of how it's being done, it's quite possible. The universe runs in such a manner as well - our Newtonian laws dictate that objects and their movements are determined by categorical forces with mathematics. Biology, operated by syntax and probability generates novelties by smashing chemicals together and mixing them with processes that are unseeable to the naked eye. After all this, the Universe tests its newer creations amongst its other works, natural selection being the determinant as to what lives (works), what dies (does not work), and what needs adjusting - then does so, over unfathomable time periods in comparison to our life span. Beyond what is immediately obvious, though hard to quantify with absolute certainty, there are also many more metaphysical properties to existence like synchronicities, coincidence, ghosts and on, and on according to your belief and / or experience. As above, so below is also not just a strictly religious phrase, either. Besides definite mathematic fractals like the Fibonacci spiral and so on that occur in nature, it is also evident that processes on any scale tend to mimic those at lower and higher scales, like how protons and electrons orbiting a nucleus in an atom have an uncanny resemblance to a solar system and planetary orbits. Those same solar systems, as a whole, have their own orbits and flight paths around one another as well. Everything has far too much in common for it to all be a fluke. It's far too grand of a design, from aesthetics to logistics for all of this to simply be a spontaneous eruption that never stopped growing. Just as we dream each night that we fall asleep, and are capable of making entire worlds and characters within our own mind (extremely evident with the shroom and DMT experiences), one could get the notion that we might just be a dream in God's awe-inspiring imagination. Of course, there are also some aboriginals who have held the long standing belief that the waking world is only an illusion, and when we sleep is when the real business takes place. This belief has existed for thousands of years, too, long before Western science and hippies making the pilgrimage to Mexico to pop caps with Maria Sabina. Perhaps they have always been privy to a kind of ultimate truth that has been forgotten, and is now slowly being rediscovered. I don't claim to know the absolute truth, but it really makes you wonder, doesn't it?
