The devices and figurative language models you'll want to focus on when composing these parts are:
Stream of consciousness:
Use fragmented sentences, run-on sentences, and illogical jumps in thought to represent the character's chaotic inner world.
Include sensory details that are disconnected from reality or exaggerated to the point of absurdity.
Use slang, colloquialisms, and informal language to create a sense of immediacy and urgency.
The walls are closing in, I can feel them. They're painted a sickly green, the color of moldy cheese. They're dripping with slime, and it's trickling down my neck. I can't breathe, the air is thick with the stench of decay. The floor is sinking beneath me, I'm falling into a bottomless pit. Help! Help! Can anyone hear me?
Introduce unrelated topics or ideas into the text, highlighting the character's inability to focus or think rationally.
The toaster is plotting against me, I can see it in its beady little eyes. It wants to burn my toast to a crisp, just like it did to that poor, defenseless bagel yesterday. I won't let it win, though. I will fight back with the spatula of righteousness! But first, I must discuss the philosophical implications of free will versus determinism.
Use exaggerated language to emphasize the character's intense emotions and irrational beliefs.
My brain is on fire, I can feel it sizzling and popping like a pan of hot oil. The voices in my head are screaming, they're telling me to do terrible things. I can't shut them out, they're too loud! I can't take it anymore, I'm going to explode!
Bombard the reader with sensory details, creating a sense of disorientation and confusion.
The colors are too bright, they're burning my eyes. The sounds are too loud, they're piercing my eardrums. The smells are too strong, they're making me nauseous. I can't feel my body, I'm floating in space. This isn't real, this can't be real.
Give the reader direct access to the character's thoughts and feelings, even if they are disturbing or illogical.
"They're watching me," I thought, my eyes darting around the room. "They know what I'm thinking, they know what I've done. I can't escape them, they're everywhere. I have to hide, I have to disappear."
Additionally, you can pair these devices with the following to further enhance the effect:
- Use repetitive phrases, illogical arguments, and accusations to make the character's rant seem unhinged and out of control.
- Include elaborate and bizarre theories to demonstrate the character's paranoid and distrustful nature.
Jump from topic to topic rapidly, highlighting the character's inability to concentrate on anything for very long.
Use short sentences, exclamation points, and all caps to create a sense of urgency and excitement.
By using these devices and figurative language modules, you can create a character whose mental state is unsettling and disturbing, making the reader question their sanity and the reliability of the narrator.
