Twice now I've had the experience where I wake up, face down, unable to move my arms or legs, but, as far as I know, able to move my head.
That seems more like sleep quadriplegia than paralysis, but I don't think that exists.
There is always the chance that I just imagined it. When it actually happens, I'm pretty fucking sure it is happening, and I have pretty good recall of it, unlike my dreams, but when I'm more awake I feel pretty convinced I was imagining it. Like maybe I had a numb arm and imagined the other limbs, but I dunno...
So could this be sleep paralysis, or do I have some sort of parasite which has latched on to my spine?
