I've had that "can't open my eyes" thing, and I think that's just part of the sleep paralysis. However, the other thing you mention could be (and I know how this is going to sound) . . . could it be partial astral projection? You could've been partially astrally projected without even knowing about it. Okay, that sounds as if I need to be fitted for an aluminum foil hat (at least that would protect me from this, maybe), but I've done some research on that and sometimes it happens spontaneously. Just food for thought.
