You wake startled in the middle of the night, terrified from whatever nightmare you were just experiencing. You try to sit up but discover that you can't move your body. You try turning your head in your wife's direction, hoping to get her attention, but quickly realize that not only can you not move any part of your body, but you can't even speak. Not so much as a whispered plea to your wife, a desperate entreaty to get her attention so that she can rouse you from this terrifying state.
