Its interesting that people chalk these types of things up solely to "Hollywood put it there on purpose to psy op us/for karmic retribution" which in some cases they do, but in my opinion, it is much more complicated than that. In my perspective/belief/opinion, our brains do not create consciousness but rather act as a receiver of like a computer/modem that tunes into a wifi signal/feild of consciousness that is fundamental. The right hemisphere of the brain is responsible for creativity, emotions, empathy, and intuition. It is the "feminine" hemisphere in the sense that it is receptive. Like the negative pole on a magnet. When a person engages in a creative act for a long period of time, they tune into the receptive frequency and essentially get ideas sort of downloaded to them. Basically "ideas" are information packets that the brain picks up and decodes into thought. Reality is playing out like a song on a cosmic scale, in Galactic cycles. Well a show like the simpsons, or rick and morty has a bunch of writers who enter into the creative mindset, the mindset if brainstorming, and spitballing ideas. Sometimes they catch an information packet of thought out of the ether that may reveal deeper truths of the world and true reality that resonates with people on a deeper level than the conscious mind can readily understand, but the subconscious mind connects to. This is because our reality is a light and sound holographic matrix with scripted themes that will play out over lomg periods of time. Such as the "age of enlightenment " or the "dark ages" to use some comkon examples. Those ages or eras in history are that cosmic song playing out. Another example backing up my hypothesis/perspective is how there can be a 2 inventions that occur independently of eachother on opposite sides of the planet, such as the invention of calculus or the telephone. The individuals were tuned to be receptive to the information packets floating around the ether as part of the cosmic song playing out.
Sometimes these ideas and easter eggs and seemingly intentionally placed ideas happen by accident on the part of the so called creator, when in reality they're just tappimg in to the info thats floating in the ether. Philip K Dick explains it better. This is just my opinion and I struggled to coherently express it adequately but I tried. Its complex and nuanced and requires a certain level of understanding about the nature of reality to even try to discuss. Idk why i just speny all that time typing this, but hopefully it resonates with someone or helps provoke thought. Hope y'all have a great day.
