I've never posted here before, so I hope this is in the right place. I'm writing a psychological horror novel shadowing my own personal traumatic experiences. The girl in the story experiences long-term high-level stress, causing her to lose clinically important hours of sleep and start hallucinating. One of the reasons she loses sleep is because she has terrifying nightmares every time she closes her eyes. The repetition of nightmares, lack of sleep, and stress is integral to the story; but how do I keep this exciting to the reader? How do I prevent them from becoming bored too quickly? I'm not even particularly fond of reading about dreams in novels, myself (for the record, I'm not writing this with any intention of publishing; I'm writing it for myself. I'm just a perfectionist, is all). My only idea is to make the nightmares themselves separate chapters. Short, long - it doesn't matter. Then I don't have to force them into the narrative every time (e.g. "She woke up screaming," "She shook her head to erase the unsettling images.") and can just jump into the next chapter if I feel like it. Any thoughts? Thank you in advance.
