This has been happening for a while now and don't quite know what to make of it. After being asleep for a few hours or so I'll wake up (and will know I'm awake), will be fully aware of my surroundings and I can't move. No matter how hard I try I can't move my limbs at all and I can't even speak. It feels like I'm in some sort of grip, like my body is encased in stone and I have to struggle with eveything I have to free myself from this grip. Seems like it takes about a good 30 seconds of struggling to free myself. I can breathe fine....just can't move. It's not like it happens all the time. It happens maybe once every month and a half or so and it happened again last night. Not saying it's this, that or the other thing. I don't know what this is but at times it's rather frightening. Ever hear of this or has this happened to any of you?
