Wow, lotsa memories. I haven't had any of these episodes in years, but i did when i was younger. Similar experiences to most of you, static noises, voices, laughter, hallucinations (often a 'succubus' in the form of an ancient egyptian female, like Cleopatra... how do i know? the eyes), i would 'see' the TV on, i mean with the sounds and programming, as if it really was on... but it wasn't. I would feel my body numbed, as if thousands and thousands of needles were sticking in them, and i would feel like i was flying through a tunnel on a rollercoaster, sometimes with lights flashing right by me.
Initially i was scared... hell, terrified. It almost always occured during a noon nap, almost never at night. As for it being linked with narcolepsy... well, i would say that the sleep paralysis began before the narcolepsy, and from the fear of it, that is how i developed narcolepsy. From the very beginning, i tried to control them... because i knew they were all in my head. Eventually after several months of severe episodes, i just told myself that these things aren't real, that i can't die from them, and whenever i experienced them, i didn't bother fighting or even tried waking up... i just became conscious of the experience, conscious of what exactly my body felt like, the sensations of being on a roller coaster, etc, and eventually i would fall back to sleep... and sometimes i would actually have some really great experiences.
Unfortunately, i do know a girl that has these episodes as well... and has had them for years.
