Dissociation is a normal response to overwhelming and life threatening circumstances.
It is the primary defense of very young children who must cope with and survive violent and abusive environments.
I found this short video on YouTube.
I like it because it provides a clear and easy to understand psychiatric definition of a complex process that all of us use at some point in our lives.
Unfortunately, I cannot find the link to the source video.
My gratitude to everyone who tells me that they want to know more about Dissociative Identity Disorder.
