One way to use 'brain fiction' in creative writing is to embrace the chaos and illogicality that often comes with it. Brain fiction doesn't always have to make immediate sense. So, when you notice these strange ideas emerging in your mind, don't be quick to dismiss them. Instead, try to find a way to incorporate them into your writing. Maybe you have a brain fiction about a city floating in the sky. You could use this as the setting for a story. Describe the architecture of the floating city, how people get around, and what kind of culture has developed there. By using brain fiction in this way, you can add an element of surprise and wonder to your creative writing.
In creative writing, 'brain fiction' can be used by first recognizing those random, unbidden thoughts that pop into our heads. These are often the building blocks of brain fiction. For example, if you suddenly have an image of a talking cat in your mind, that's brain fiction. You can then take that and develop it further. You might create a whole world where animals can talk and use that talking cat as a main character. Explore the implications of this brain - created idea, like how the society of talking animals would function, what their language would be like, and how they interact with humans or other non - talking animals. By delving deeper into these brain fictions, you can create rich and unique stories.
We can use brain fiction as a source of inspiration. Just let your mind wander and jot down those wild ideas that come up, which are all forms of brain fiction, and then build a story around them.
