Don't confuse a split personality with merely changing the focus of one's attention from objective to introspective. The mark of a good writer is the ability to make that change convincing and definitive. My writing is objective, but I venture into the surreal world of writing where my changing into a cockroach before breakfast seems to be a normal thing. A lizard merely reacts to a stimuli in a biologically programmed response, the robot too just follows the program. Humans can alter their program as they will. Investigating the thought processes of alien life forms, the human female in particular,(AIIFIN)is that cutting edge of that surreal thought process.
