Imagine constantly fading into different personas without conscious awareness. Having large gaps in your memory that you cannot explain. Other people commenting to you about things that you did of which you have no recollection. This is the life of someone with Dissociative Identity Disorder.

Robert - host personality, a responsible professional that does business with China and India via the Asia Society. 

Tommy - cruel, abusive teenager who finds ways to punish the other personalities inside Robert Oxnam.

Bobby - endearing 10-year-old child who is smiley and whom everyone likes.

Baby - abused boy who never recovered from the anger and pain of the severe abuse perpetrated on him at a young age

Librarian - keeps everything in strict order and plays to Oxnam's need for predictability and stability

These are just some of the eleven alters that Robert Oxnam experiences as part of himself. Sexually abused as a baby, Oxnam's sense of self was shattered into many pieces. Years of therapy managed to achieve some sense of cohesion. The eleven portions of self were then fused into three: Robert, Wanda and Bobby.

It was quite interesting to read a male account of dissociative identity disorder, especially since this is a problem that primarily affects women.
