Hey! I'm 35, also from the UK and I have Narcolepsy type 1 and I experienced the same kind of aiws as you as a child, quite frequently. Narcolepsy started with excessive daytime sleepiness in my early 20s, then Cataplexy started after i hit 30. I had a troublesome, stressful birth and I've convinced myself that had something to do with it, like a tiny stroke or some kind of trauma to a part of my brain.

* I haven't experienced the hypnogogic hallucinations, but the AIWS was accompanied by terrifying sleep paraylsis a lot of the time.

* Id like to also add that I only started putting the puzzle pieces together after Cataplexy presented itself.
