The brain constantly picks and chooses
The filtering function within the brain controls your reality
Have you ever heard of brain-stem reticular activating system? Sorry to be daunting from the start.
Extremely simply put, it is an organ which functions as a filter in the brain.
So what does this filter do?
For example, is there any place that you go to every day? If you are employed, is there an office you commute to almost daily?
If yes, let me ask you something.
Can you tell me the color and the design of the office floor?
Did you just go "what....?"
There is a few people who remember them correctly, but majority of us are not able. You might try to remember and come somewhere very close, but when you do look at the real floor to confirm, it could be completely different.
This is the same floor you are looking at almost every day.
Even the face of the wrist watch we look at quite often, when we actually try to draw the details, most of us cannot.
If you like, go ahead and try drawing your watch (put it away first). I bet you are not able to precisely draw where the logos are located, shapes of long hand and short hand, shapes of the inscription, etc.
A wrist watch is something you look at more often than the office floor, is it not?
Why does something like this happen?
The filtering function - brain-stem reticular activating system - is the reason why.
This filter in many different ways has a function of closely looking only at things and matters you are conscious of.
Even when you think you are looking at "everything", in actuality you are only looking at the "parts of things" you are conscious of.
The lenses called "eyes" may be capturing everything, however it is the "brain" that actually sees, therefore you have not actually seen anything without brain-stem reticular activating system capturing them.
For details on the brain seeing things, please refer to Human beings have extremely limited vision.
As explained, human beings look closely only at things they are conscious of.
If that is the case though, what could happen?
Simply put, realities differ from one person to the next. What each of us is conscious of determines the view and the reality appearing in front of our eyes.
Let me give you a simple example.
You are walking in a town that you know well, and suddenly your tooth starts to ache.
"Ouch, this hurts. Nooo!" and you look around yourself and realize "wow, I see so many signboards on dentist offices".
From this particular point on, your reality has changed to "there are quite a few dentists in this town".
I assume you understand this logic?
I believe we all have experienced something similar before.
We are covering topics from brain science (cognitive science） here, and together with quantum theoretical (quantum mechanical) interpretation, the understanding of "consciousness changes reality" should be deepened.
