How to determine the split personality in a person?
Interesting fact: the most popular way of a person with a split personality is Dr. Jekyll and Mr. Hyde. According to the novel by R. Stevenson, they make films depicting Hyde as a hulk who can jump on rooftops. During the transformation on it is always torn clothing. But the way this image is presented is different from the description of Hyde in the original story. Stevenson was short and frail young (younger than Jekyll), a man whose hands had increased hairiness. The only truth that films show is that this creature causes unpleasant feelings to all who see it.
