I wonder what you all think of as the difference between "horror" and "terror."

The two words describe two very similar but somehow different emotions. It seems to me that "terror" might be what you would experience if you were, say, about to run up Omaha Beach on D-Day while being shot at by machine guns, and "horror" is what you would experience right after you actually got shot. That is, terror is a more intellectual fear based on your rational response to a situation, and horror is a more emotional response to a situation, involving fear and disgust.

Any thoughts on this?
