People with nightmare disorder tend to have lower blood levels of triglycerides, total cholesterol, and low-density lipoprotein (LDL) compared to healthy individuals. The study compared 15 people diagnosed with nightmare disorder to 15 healthy controls, measuring their lipid profiles through blood tests. The findings suggest a link between nightmares and low serum lipid levels.
