Container Exercise
Stabilization Resource
A visualization technique for temporarily setting aside difficult thoughts, memories, or emotions between processing sessions — storing them in an imagined container so you can come back to them when you're ready.
Also known as: container, container visualization, mental container
The container exercise is a visualization technique for temporarily parking difficult material — memories, thoughts, emotions, body sensations — in an imagined container of your own design. You place the material in the container. You close the container. You set it aside, trusting that it will still be there when you decide to return. It is one of the most reliable between-session stabilization tools in EMDR-informed practice.
The exercise works because the nervous system responds to clear signals about what is being processed now and what is being stored for later. Trying to “just not think about it” tends to backfire — the material resurfaces. Deliberately placing it somewhere specific, with an intention to return, lets the system actually set it down.
How to build your container
- Design the container. It can be anything: a heavy wooden chest, a steel safe, a velvet-lined box, an iron vault, a basket with a lid. What matters is that it feels strong enough to hold what you want to store, and that it closes in a way that feels definitive — a latch, a lock, a seal.
- Locate it. Where does the container live when it’s not in use? In a specific room in your imagination, buried in the earth, at the bottom of a lake, on a shelf in a library. A defined location makes it easier to close the visualization cleanly.
- Rehearse. Practice opening the container, placing a neutral thought inside (e.g., “what to make for dinner”), closing it, and moving on. Your body learns the sequence.
How to use it
- Between sessions. Material that came up during processing but isn’t finished can be placed in the container until the next session.
- When flooding threatens. If emotional intensity rises past your window of tolerance outside of a session, the container can hold the material while you ground and stabilize. See emotional flooding.
- For everyday intrusions. An intrusive worry, an unwanted memory in the middle of a meeting — the container is available for those moments too.
Contained is not the same as suppressed. The container holds the material safely so you can return to it on your own timing, not avoid it indefinitely.
