Our deceptive internal models and maps

We see things based on our internal model. The internal model is the blueprint of our reality that gets constantly updated as we go through life.
We only get the information that our brain thinks is important to us, the rest is considered superfluous and hence discarded.
If we start consistently thinking about white cars, this gets incorporated into our internal model, and the number of white cars we see seems to increase.
The white cars were always there, we just "forced" our brain to notice them by thinking about them.
We also get easily deceived by optical illusions when our brain tries to fit visual information in its existing and unsuitable internal model.
As a result we get the wrong image "manufactured" in our brain.
Our senses, because of our biology, give us only a fragmented view of reality. There are sounds we can't hear and colors we can't see.
Our brain is a storyteller and our reality is whatever it tells us.
This "faulty" perception also shapes our emotional and social reality.
When our mood is jolly, our internal model primes us to notice positive events, friendly faces, and opportunities, while filtering out anything that is not in tune with how we feel. Conversely, when our mood is gloomy, the same filtering system amplifies threats and problems while simultaneously minimizing positive experiences.
This is the reason why two people can have wildly different experiences while attending the same event for example.
One person's brain may construct a narrative of elevating and entertaining social interactions, while the other person's brain may come out totally disappointed and slighted.
Our internal models actively construct our social reality.
Our brain or our storyteller make us experience different realities based on our mood, thinking and general disposition.
What we consider "objective truth" is actually our brain's subjective interpretation filtered through our unique internal blueprint and societal filters.
