I think that, for the most part, I live inside my head. What I mean is: I don't see the world as it is, I merely take cues from the world. Like improvising over some chords as opposed to playing directly from a score. Of course I don't fabricate my own facts, or believe in what cannot be proven; I trust science and I do not have faith in an unchanging dogma. I merely take what is presented to me and use it to fill in the rest. Sort of like seeing the universe as a writing prompt. I'm sure most people do this, whether they are aware of it or not.
One example I'm aware of is places. In my mind, the places I go are different than how they are in reality. There are many versions of each place: the place as it exists, the place as it exists in my mind and the place as it exists in the minds of everyone who has ever been to that place. These are all different places.
The more I visit a certain place, the more prominence it has in my mind. I have been to Chicago, so a form of Chicago exists in my mind. I go to my bathroom regularly, so my bathroom exists in my mind as a single place. Mentally, my bathroom is bigger than Chicago, since I have been to my bathroom more than I have been to Chicago. Obviously this is not true in real life, it's just that my bathroom has a more developed style and presence in my mind that Chicago does. This is applied to many things, the people I meed, the clothes I wear, even the websites I visit.
In this way I fabricate my own little world inside of my mind, in which all aspects are connected. Sometimes this world deviates from what is in the real word, but the changes are trivial enough that they do not go against science. The sciences are the lines in which I colour my world. Though it is acceptable to colour outside of the lines on occasion, it is irrational to do so if it alters the intended meaning of the work.
I obviously like my world better than the real one, though I accept that I have to face both of them.
