My sister's eye color.. changed dramactically... after she had surgery on her feet.. she was in a great deal of pain.. we were young.. I was 12.. and she was 14..

It was at the time that the Exorist movie was around... and I just remember.. so vividly.. that I was scared to death of her... just because of the movie and the eye color change..

They did go back to their original color... after she was out of pain...

but gezzzzzzzzzzz.. I still haven't forgotten..
