Waking up IN a Nightmare

Ever been in a nightmare so revolting that you wake up with a trauma? Cold sweat pouring down your face, a heaving chest and a prayer wishing that it won't come true. Imagine that nightmare happening for real and all the trauma and pain you will experience will be tenfold. You can't speak and your mind becomes blank to digest all that you are experiencing at that moment. The nightmare just plays back in your head and all your body can muster is to freeze and stare blankly to space hoping that sometime you will wake up (but as a matter of fact you are).
