Dissociation, Attachment Trauma & the Brainstem with Nikki Nooteboom

In this episode of Going Inside, Dutch therapist and trainer Nikki Nooteboom joins John to explore how neurobiology is reshaping trauma therapy. From the vestibular system to dissociation and the default mode network, Nikki breaks down the deep physiological roots of trauma — and how to work with them more effectively in clinical practice. If you've ever wondered why some clients can't stay grounded or why insight alone doesn't lead to healing, this conversation is for you.

🔑 3 Key Takeaways

1. Why Knowing Isn’t Healing: Insight alone doesn’t shift trauma — the body must first rediscover safety through bottom-up integration.
2. The Vestibular System’s Role in Trauma: Learn how trauma disrupts orientation and balance at a neurological level — and why that matters more than we think.
3. Beyond Coping: Creating Real Safety in the Brain: Discover how consistent, structured grounding practices can actually rewire a brain organized around survival.

In this deeply moving episode of Going Inside, John sits down with somatic coach Marina Shriner for a raw and resonant exploration of how trauma hides in the body—and how it silently shapes our relationships, self-worth, and emotional patterns.

From immigration and war to abusive relationships and business breakdowns, Marina shares her personal healing journey and why talk therapy wasn’t enough. She reveals the powerful truth about what happens when we stop trying to think our way out of trauma—and start feeling our way through it.

Key Takeaways

🔑 You can't outthink trauma — Marina shares why healing requires going into the body, not around it.
🔑 The fixer/rescuer part may be protecting your inner child — Learn how over-functioning in relationships is often a trauma response.
🔑 Grief doesn’t go away—it waits — Discover how unprocessed grief and emotional pain can live in the nervous system for years if left unfelt.

In this episode of Going Inside, John Clarke sits down with Jessica Fern—IFS-trained trauma therapist and author of Polysecure—to explore what really happens inside our systems when we open up relationships. They unpack the intersection of attachment, trauma, and non-monogamy, and how IFS brings clarity and healing to the parts that get activated. Whether you're a therapist, curious about ethical non-monogamy, or working on your own attachment wounding, this conversation offers powerful insight, practical frameworks, and plenty of aha moments.

Key Takeaways:

• Why "opening up" a relationship often opens old wounds first—and how IFS can help you meet the infant parts crying out for safety.
• The surprising ways codependency, polyamory, and secure attachment collide—and what people get wrong about each.
• How the "shame triangle" shows up in modern relationships—and why your inner critic may be the loudest part in the room.
