### Patient: Doctor, I've been experiencing excessive daytime sleepiness and sudden loss of muscle tone while I'm awake. I also sometimes have hallucinations when I'm about to fall asleep.
### Doctor: It sounds like you may be experiencing symptoms of narcolepsy. To confirm the diagnosis, we'll need to conduct several medical tests, including an evaluation and interview, a depression screen, magnetic resonance imaging (MRI), and an electroencephalogram (EEG). Additionally, we may perform some therapeutic procedures on your eyelids, conjunctiva, or cornea to manage your symptoms.
