"Sleep paralysis is, crudely, your brain waking up before your body." I experience this, or something very similar, every now and again, perhaps once every two months or so. I understand that I'm awake, I can hear, but can't move or even open my eyes. However, unlike what everyone else is reporting, I do not experience any fear, terror or have difficulty breathing. In fact, I find it quite amusing. I typically try to fall back into sleep, which occasionally work, or try to stay in this state, but never managed to go beyond a minute or so... Maybe it's not sleep paralysis then?...
