If you have the experience of feeling awake but cannot move your body, you must realize that you are in what is referred to as a "borderland state." It is this state where folks may have "Out of Body Experiences." If this happens to you often you should do the research on OBE.
Now then, if in this state you experience and "abduction" and meet some strange form of creature, you must know that the only action you can take is MENTAL. They are doing the "astral projection/out of body" thing. I did successfully fight off one of the greys using mental imaging. I thought of flaming kung fu stars which I mentally threw at him, and he did vanish.
I urge you to research and study all you can find on the OBE and on mental imaging.
Imaging is a very powerful tool in all areas of life.
