This is what she had to say on her YouTube channel:
I have narcolepsy with cataplexy, and it can be very frustrating to try to explain what it's like to people who have never seen narcolepsy in real life, and how much of a struggle it can be. Most people think that it's funny until they see what actually happens, or they are completely unprepared and get really scared and panic.I filmed this by accident, and it was really weird to go back and watch later from an outside perspective. I am posting this video as a way to help educate people, so please no trolling. Just like people with epilepsy, I can't control having a sleep attack or cataplexy any more than they can control having a seizure. Thank you for your understanding.
