THis is a bit funny question, following "can-one-name-count-for-two-people" but I think Halachically legitimate:
How a sick person with Dissociative Identity Disorder (Multiple Personality Disorder) should be mentioned in the prayer for health on Shabbos?
My consideration is that we pray for "רפואת הנפש ורפואת הגוף" and that person has one body but (probably) two souls.
Why should what they 'think' affect what we say?
Truly, the question of our time.....
