Container exercise: what it is and when to use it

A container exercise is an EMDR stabilization technique: you picture a strong, personal container, like a safe, a chest, or a vault, and mentally place a disturbing thought, memory, or feeling inside it to set aside for now. Therapists teach it in Phase 2, EMDR’s preparation stage, and it also works well as a stand-alone coping tool for everyday overwhelm.

How do you build a container?

Per a 2011 clinical column in the Journal of EMDR Practice and Research, you start by picturing something strong enough to hold whatever needs to stay out of view for now: a bank vault, a treasure chest, even a bubble, whatever feels personally secure. Add real detail, a lock, thick walls, a location, then imagine placing the disturbing material inside and closing it. EMDRIA, the EMDR International Association, places it early, in Phase 2 of EMDR’s eight phases, the preparation stage that comes before any memory processing begins. The point isn’t to make the thought disappear; it’s to choose when you look at it again.

What is a container exercise used for?

Katy Murray, who wrote that column, describes it as especially useful for trauma-related intrusive thoughts, ongoing worry, and compulsive or addictive urges. Therapists also use it to close a session that didn’t fully resolve, so a client isn’t left carrying raw material between appointments. The container isn’t meant to sit empty forever. It’s opened again, on purpose, once there’s enough support to look inside.

How is a container different from a safe place or grounding?

A safe place is somewhere calm you visit and rest inside; a container does the opposite, storing distress out of view rather than inviting in calm. Grounding is different again: it anchors your attention in the present moment, through your senses, rather than storing anything at all. All three are resourcing techniques, ways of widening your window of tolerance so a hard feeling stays manageable instead of taking over. Most people learn more than one, since stabilization usually calls for a few different tools.

Does a container replace trauma processing?

No. The same clinical column is explicit that a container only creates a helpful state change in the moment; it doesn’t reprocess the memory itself. That deeper work happens across EMDR’s later phases, guided by a therapist, and once a memory is fully processed, the container isn’t needed for it anymore. Until then, it’s a legitimate coping tool, not a shortcut around the real work.

Can you use a container exercise without a therapist?

Yes, for everyday overwhelm. Picture something secure, place the thought inside, and notice where the relief shows up in your body. If nothing ever feels strong enough to hold what surfaces, or the contents keep leaking back out no matter what you try, that’s often a sign of deeper trauma material that goes better with a professional’s support than self-guided practice alone.

EmEase, a self-guided EMDR app, is built around bilateral stimulation rather than containment. The two pair naturally: use a container to close out a self-guided session, setting aside whatever surfaced until you’re ready to return to it, at app.emease.com.
