Julie Flygare’s battle with the condition, which has caused extreme exhaustion and even hallucinations, began in college, reports Reader’s Digest.

“It became a sort of schedule I kept,” Flygare tells Reader’s Digest. “I couldn’t go to class early because the urge to sleep was so strong, so I began this habit of excusing myself to the bathroom repeatedly just to slap myself or splash water on my face so I could stay awake,” she says. Her symptoms of narcolepsy grew terrifying when she began hallucinating at age 21.
