Three and a half years ago, when I was diagnosed as a Schizophrenic, I experienced some dissociative symptoms and I believed that I was both Captain Kirk and Spock.  The irrational and logical personalities really clashed, and I believed that I was the two characters combined.  Some notable pairs that I believed I was, were Tom Hanks and Meg Ryan, and Jesus and God.

These split personalities evolved into the entire crew of the Enterprise,  acting as captain, commander and communications, as well as engineering.   The hospital I stayed in became the Star Ship Enterprise, with the flat screen television as the view screen, and my bed being the quarters.

What about you?
