Creating reality one question at a time

The narrative in the part of chapter four that I’m writing is sparse. The section is based on a folklore tale that has lots of sketchy detail and imagery that is far from reality. How much weight in reality my novel has is something that I have struggled with in the past. It has previously tripped me up and stopped me from getting into writing. What is reality anyway? How “real” does a story need to be? Is truth stranger than fiction? In reality people believe in ghosts, some cultures honour their ancestors as if they still live, and people build their beliefs and values on things that they cannot see, touch or experience. When is something far-fetched? Does it matter? Can I write questions forever without ever answering any of them? All these questions and more plagued me for a long time but then I came to accept that none of the questions have to matter.
The world is made up of individuals who have unique experiences and are able to identify with others based on the shared experience of the human condition. That is my understanding and logic of what reality is, and based on it I no longer struggled over the idea of reality within the context of my novel and writing my novel began. I need to be clear about what I’m writing and not lost in the peripheral variables of the unknown.
