The Wizard of Oz is a 1944 movie starring Judy Garland which is sometimes used as a metaphor to describe the disconnect between the dissociated reality of the personality-disordered individual (Oz) and the real world experienced by the Non-PD (Kansas). The metaphor is based on the iconic phrase: "Toto - I've a feeling we're not in Kansas any more".
In the classic 1939 MGM Musical, "The Wizard of Oz", Dorothy (Judy Garland) a young girl from Kansas, is thrust by a tornado into the freakish world of Oz, populated by munchkins, wizards, witches, and flying monkeys. The movie chronicles her adventures as she searches for a way to get back to her home in Kansas.
Not in Kansas Any More
In an iconic scene, Dorothy emerges from the house carrying her dog Toto from the house which has just been transported by a violent tornado - or "twister" into the land of Oz. As she observes the strange new colors and textures of the new world, she utters the phrase: "Toto - I've a feeling we're not in Kansas anymore".
The phrase: "I've a feeling we're not in Kansas anymore" has developed into a popular cultural icon for any situation in which reality seems to take a back seat to a new order of freakish rules, people and events.
The phrase has also been adopted by a number of Chosen Non-PD's who identify with the feeling as they discover the strange dynamics of dissociation or a new dysfunctional relationship and begin to wonder about the wisdom of getting involved with a person who has a personality disorder. In this analogy, "Kansas" becomes synonymous with normal old situation they came from and "Oz" becomes synonymous with the crazy new world they are experiencing.
