It's not exactly sleep paralysis, they said it was an overactive brain/imagination. I could move, my brain just refused to let go of the dream making feel so real it was impossible for me to move beyond what I could see (which was basically the bed and no further) and since I'm naturally quiet when scared or spooked (I'll meep at most but never scream which, if you think about it, is a really bad response should someone try to accost you, though I'm better at shouting now than I used to be)
I just remained 'locked' in my own brain and the dream's aftereffects until someone managed to drag me out of it or found me...
Even now I'm still like that whenever that happens. Though it's lessened from every night as a child to none for years and now it's back to once every few months and then some 'insomnia' afterwards...
I also spend less time afraid to move simply because I can reason through it now, even if it still takes me quite a bit of convincing. I just feel like such a coward afterwards, so I always hope it'll never happen when my friends can see me. I just feel so broken the entire day then...
Hikaru no go was pretty good indeed!
