Summary of: The Myth of Sanity: Divided Consciousness and the Promise of Awareness
By: Martha Stout


In ‘The Myth of Sanity: Divided Consciousness and the Promise of Awareness’, Martha Stout explores the concept of dissociation and how it serves as a double-edged sword. Dissociation is a psychological phenomenon that allows the brain to disconnect emotionally during traumatic events, serving as a survival mechanism. However, it can have negative effects, such as causing unexpected dissociative reactions and contributing to dissociative disorders. In this book summary, we delve into the intricacies of dissociation, its effects on the brain, memory, and how it manifests in traumatized children and adults. We also examine how to confront past traumas and promote healing.

The Double-Edged Sword of Dissociation

Dissociation is a natural survival mechanism that disconnects us emotionally from traumatic situations to help us act calmly. But dissociating has its downsides. After dissociating during a traumatic event, our brains can associate benign situations with trauma and toss us into dissociation again unexpectedly. Beverly’s story is just a small example. Severe trauma can cause even more intense reactions.

The Brain’s Response to Trauma

Trauma has a profound impact on memory formation and can lead to dissociative reactions. The amygdala, the emotional processing center of the brain, becomes overwhelmed, preventing the hippocampus from organizing and integrating information. Traumatic memories exist as isolated sensory images or bodily sensations and may not be connected to language-processing areas. The effects of this process are illustrated through the story of Julia, a survivor of childhood abuse who experienced severe memory gaps. Julia’s experience highlights the importance of understanding how trauma affects the brain’s memory-storing processes.

The Unfathomable Experience of Dissociative States

Dissociative states, such as fugue and demifugue, can cause individuals to lose time or have out-of-body experiences. Traumatic memories associated with everyday life can trigger fugue states, leading to individuals feeling detached from reality. On the other hand, demifugue is more common and entails a temporary feeling of separation from reality. Childhood trauma survivors are more likely to experience dissociative states, making it vital to understand why this connection exists.

Vulnerability of Children to Trauma

Children are highly vulnerable to traumatic experiences, and this vulnerability can have long-lasting effects on their psychological well-being. Even witnessing secondhand violence like muggings and shootings can traumatize children, and global tragedies like disasters affect millions of children. Although most children are not victims of abuse, disturbingly high numbers experience it before the age of 18. Traumatic situations disrupt or violate a child’s worldview, making them feel helpless and overwhelmed. As a result, their sense of meaning is highly susceptible to influence by overwhelming emotional situations. Matthew’s experience of dissociation as an adult due to his parents’ verbal fights during his childhood is an illustration of this vulnerability. Childhood trauma can have severe and lasting effects on a child’s psychological health, including dissociative identity disorder in extreme cases.
