The stories you believe to be true are the ones your life will become.
It's amusing to me that we refer to people who live in their heads as detached, disturbed, or mad, when reality for anyone is actually a matter of the individual's state of mind. The mad truth - all people live in their heads. Whatever you think life is, it is.
I live in a world where people are guided by limited imagination; only facts that are favorable to them are truths. They are unable to live anyway else. When a person finds out that a fact is against them, it's usually because it's the truth. No one tries to step outside of the edge of reason. No one tries to step beyond the edge of the world.
I do think that our perception of reality is fragmentary, and in 20th-century literature, it’s totally normal to not describe reality as something whole and completely transportable and explicable. That’s been accepted in novels. But genre films always pretend that reality is transportable, which means that it is explicable.
People enjoy the passion of delusions. However, the world is built on a basis that if you free yourself, you find yourself within another illusion. There is always a truth hidden within a truth. It is no different from illusions and deceptions of reality. The question then becomes - how does one become truly free?
If you know something is an illusion, why pretend it is reality?
