I was around 13 when this stuff happened. Now, looking back, I'm not sure if some of the sleep paralysis was a symptom related to narcolepsy. (I was reading about it apparently sleep paralysis upon waking is a symptom.)
I had been falling asleep and waking up within an hour of falling asleep with a weird feeling in my stomach. I can't really describe it... I think the closest thing to it is when you're doing crunches and your muscles quiver from the strain - only I was completely relaxed. That's how it started.
Then I started waking up and not being able to move or speak. That terrified me and it persisted no matter what I did.
One night I fell asleep and 'woke up'. I was absolutely completely awake while I was asleep. It was like the past nights, I couldn't move or speak. Only this time there was this sort-of vortex at the end of the bed and I was being pulled into it. I could turn my head and there were three people standing in my room. They were dressed in sort of Victorian clothing and it was sort of maroon or scarlet colored. Since I couldn't speak I was screaming in my head for help but they just sort of looked at me. I don't know if the people were good or bad but going by the fact that they didn't help me and that I was afraid when I saw them, I'm assuming they weren't good. Then I woke up for real this time.
I don't really know if this is a 'ghost' thing but I found it very peculiar since very soon after that, my sleep paralysis stopped. I've never seen the Scarlet People (that's what I call them). Nothing has happened since then, the thing or whatever it is hasn't done anything like moving things, or speaking up, for all I know it could be good or evil, it could be an guardian angel or a evil entity... Who knows?
