Trauma-Worlds and their Transformation: Moving beyond a life built around fear, dissociation and shame

The Embodiment Conference – Online

Friday October 23rd, 2020.

2pm UK time live. FREE to watch for 48 hours afterwards.


When we suffer experiences that are emotionally damaging, survival systems are activated inside of us. These systems are built around fear, dissociation, and shame. They change how we feel and think about both ourselves and others. They also change how we behave.

In the short term these changes are protective, but in the long term they create terrible suffering.  Indeed, as the changes are incorporated into both our minds and bodies, we start to live from within a reality that is distorted, self-critical and dulled. I call this reality a ‘trauma-world’.

In this presentation I’ll describe trauma-worlds, the protection that they offer and the suffering that they create.  I’ll then explore how we can transform our trauma-worlds, and move away from their distortions towards a more compassionate and vibrant life.
