Today I’m joined by trauma therapist and EMDR trainer Thomas Zimmerman to talk about Flash technique, a fast-evolving approach that aims to process traumatic memories with dramatically less distress, especially for people with complex PTSD and dissociation who may struggle with the “admission cost” of standard EMDR.

We unpack what Flash is, why it can work even when someone cannot tolerate long activation, and how it differs from simply “distracting” yourself. Thomas explains his predictive processing version of Flash through a clear image: instead of dumping the whole memory into awareness, we bring in one tiny “bean” of it, then shift into a strong pleasant scene to create the kind of sensory mismatch that helps the nervous system update. We also explore why dissociation can be a brilliant adaptation, how culture shapes what we think healing should look like, and why resourcing can be practical, tolerable, and even fun.

We get concrete about clinical application too: the core resources Thomas teaches, why sensory grounding matters, how parts-informed consent changes the pace, and when to slow down for DID or severe amnesia. We close with where the research is headed, what Thomas is building next through trainings and a nonprofit, and why accessible trauma therapy could matter at a societal scale.

If this conversation sparks something for you, subscribe, share it with someone who’d benefit, and leave a review. What’s one idea from this talk you want to try or think about more?
