Wow this is so close to my symptoms as well it’s interesting to read and see their few differences.
I too have a mixture of full narcolepsy and cataplexy attacks - but more cataplexy like the article.
I am conscious I just can’t move, I also feel a sinking feeling before it starts so I get just a few seconds warning which can help a little. My partner knows my distinctive “uh oh” I always utter before I leave for a bit.
When it happens I am in a new space and I see a new colour, it’s similar to purple but also with a lot of black mixed in, it’s not one solid colour but it morphed and swirls like those animated Gaussian noise functions. Initially it was scary but I feel like I know this place now, I can hear everyone, but I cannot move or respond or feel anything, I enjoy the serenity of being there now, it’s a little chill out zone, gifted to me.
I also dream while I’m awake, but I know it’s happening (visual and audio hallucinations) because the transitions are instant and very high res (it feels like reality, it’s never been blurry like the poster says) and since I know it’s a dream I have full control, I can modify it willingly (I enjoy adding waterfalls everywhere for some reason, and also moving about in a flying car) it’s not a conscious driven narrative I came to that conclusion because things still happen that surprise me or I mispredict events that then am able to understand why they happen with logic, which I think is very weird, my subconscious is able to build a dream so elaborate that it can surprise my consciousness with unexpected events? Isn’t that mind blowing?
It has a lot of downsides though, I can collapse any time without much warning, sometimes 1-2 seconds. it can happen during business meetings, crossing the street, balancing on places you really don’t want to fall, and no driving of course.
I take medication which helps a little but gives me terrible headaches and other unpleasant side effects.
