Have you or someone you know been diagnosed with narcolepsy? What were the signs, ie how did you know or suspect it might be a problem?

The reason I ask is because I've finally decided to get something done about my sleep (or specifically constant feeling of tiredness) so I was doing some reading online and have realised narcolepsy isn't just about people falling asleep in the middle of the sentence/their dinner/while driving up the road. Specifically, the weird REM-onset hallucinations etc, I've been having these for years (I call them my "crazy falling asleep dreams") and I've had them all - hallucinations, paralysis, noises inside and outside my head, etc. OK I know these can also be a sign of sleep-deprivation in a more general sense, but geez, I'm now wondering if this might be the reason the nanna-napping urge has always been so strong in me.

I'm booked in to see GP in a couple of weeks to get a referral for a sleep study, just interested in case there are some narcoleptics around who have been diagnosed even though they've maybe had more subtle sets of symptoms.
