Lol nap attacks. Always imagined people just thumping out mid stride.
I don't see why not.
Narcolepsy isn't retardism. Since, unlinke retardisms, you can stop those attacks, and there isn't any specific things to launch them. Retardisms are stupid things you do in certain situations or times, they are more like reflexes or habbits, it is easier to get than remove, for example, I've a habbit of nearly crushing the face of the person why touches my left shoulder from behind, luckly, I have never hit anyone because of that reflex, also other, when there is a long meeting/talk and I'm sitting, my legs start shaking.
+ When I'm waiting for something, and I need to wait at some point, I start walking circles.
