Reliving memories long after trauma. Why does it happen?


I just returned from a week’s trip to Lebanon to train participants in a Scripture-Engaged mental health-informed trauma healing program. It was a wonderful experience. I made new friends, heard important stories of hardship and God’s faithfulness. I ate good (no, great!) food, and saw some beautiful scenery. Now, as I try to get my body clock back on home time zone, I’m waking early. In those wee hours of the morning, many of these memories come without any seeming effort on my part. There are great ones–laughter, sweet times, a poignant story of pain and heartache, a story of courage–and the brief moments of terror in several taxi rides. Since we survived the taxi rides, these latter memories are no longer negative as much as they invoke a chuckle or two.

In a small way, I’m reliving and recalling memories. I can smell the smells. I can feel the tension of riding in the front seat of a taxi going 60 miles an hour on a city street or the driver’s attempt to squeeze between a barrier and a large truck at a high rate of speed with only inches to spare. I can feel it and see it. And I didn’t even try to recall either the good or the bad. They just appeared.

This is how traumatic memory works. You experience a trauma and later flashes of memory–painful, shocking, unwanted–appear after the subtlest of triggers. You do not merely remember it, you feel it. You taste it, as if it were happening again. They come in bits and pieces, flashes and images; rarely in a linear sequential fashion.

While most good and bad memories fade and are replaced by new and more salient experiences, some memories stay powerfully strong and consistently intrude into the present. Even when we tell ourselves, “We’re safe now. We are no longer in danger” or “You’re not a child anymore, you are grown up and don’t have to be afraid of being hit,” the memories and associated feelings keep coming. It is as if your logic and perceptions aren’t able to moderate the response.

Let me give you a little silly example. I once became violently ill  for 4 days after eating deli turkey. To this day I cringe and feel stomach pain when presented with deli turkey. That experience was more than 12 years ago. Yet still I react. I know that what is in front of me is not tainted but it doesn’t seem to matter to my stomach.  Sure, the reaction I have is minimal and faded compared to immediately after my illness. But it is not gone.

Why does this happen? What are the processes in play that keep us experiencing and reliving what may be old and distant–as if it were still present? What follows is brief and a relatively simplistic summary of two very complex processes. Use them to help you understand yourself or a friend and to increase your empathy for those trapped in such processes.

Memory and the Connected Self

Psychology focuses much of its work on the individual person–the self. However, the self never exists outside of social connections (or disconnections) with others. Our understanding of our self begins at birth with billions of interactions (smiles, frowns, words, touch, etc.) with others. As we develop and become aware of ourselves, we often have key experiences of success or failure that continue to shape our sense of self long into the future. Find someone with a powerful sense of failure and you will find someone who will struggle to interpret present success as indicative of who they are. Whether success or failure oriented, both outlooks form on the basis of how we perceive that others see us. It seems that shame and humiliation act as intensifiers making it hard to alter our sense of self even after corrective experiences. They turn me from “bad things happened to me” into “I am bad.”

Memory and the (dis)Connected Brain

In simplistic language, the brain is an amazingly connected and efficient organ firing constantly day and night. Memories are stored and accessed, intensified or eroded, and often altered through the firing of neurons. The efficient brain “learns” to access information quickly. Just as you no longer have to think to insert your key into a lock the right side up, you also no longer have to consciously recall a memory–it just happens. Because multiple hormones and structures in the brain are involved in memory formation, it stands to reason that ignoring a life-altering memory (and the full-bodied experience of it) is next to impossible. Structures like the brainstem, amygdala, hypothalamus, hippocampus are evaluating and communicating (or not) with high-level processing within the cortex even before you know it. Thus, a memory and its reaction is already well-underway before a person can think and critique such a memory.

So, are we doomed to be controlled by our past?

No. There is ample evidence that we can form new connections and minimize intrusive and unwanted memories. The brain is plastic. It is adaptable and changeable. And yet, we are not in the age of the MiB neuralyzer. God does not usually remove us from our histories or make them so distant they have no effect on us. Adaptation takes time and energy and rarely is so complete that the person no longer feels nothing when they recall a painful event (in fact, feeling nothing might be rather dangerous as it would be a denial of reality).

So, the next time you are beating yourself up for still struggling with the past (or are questioning why a loved one can’t move beyond a trauma), be gentle. Consider instead how you might develop a corrective response that accepts what has happened and gives opportunity for a new second response after the first automatic reaction.

Why we react and then think

Ever wonder why? Check out this quote by Richard McNally¹ about the role of the amygdala,

LeDoux discovered two pathways for activating the amygdala, a subcortical structure integral to the experiences and expression of conditioned fear. One pathway rapidly transmits sensory input about fear stimuli to the amygdala via a subcortical route, whereas the second pathway passes through the cortex, taking twice as long to reach the amygdala. Subcortical activation of the amygdala makes it possible for a fight-or-flight reaction to begin even before information about fear-evoking stimulus has reached conscious awareness via the cortical route.” (p. 178, emphases mine)

If this is true, then in anxiety and intense emotion-producing events our brains begin the reaction phase prior to any thought processes. If true, then we might consider

  1. The goal of trauma treatment or anger management is NOT to avoid having reactions but to more quickly reach cognitions and alternative emotions that help moderate a negative reaction
  2. the empirical evidence for the clinical process whereby a client adopts a neutral reaction as opposed to a negative reaction is quite lacking. There are a number of models that process to “cool down” the amygdala, but these treatments often lack serious empirical support.

So, the next time you instantly react in a way that bothers you, don’t be so hard on yourself. Instead stop yourself, take a deep breath, work to analyze the situation and to lean into a post hoc truth. We have our hands full enough with what we know we need to do, we don’t need to worry so much about our first reaction.

Inside the brain of a Christian Psychologist


Ever wanted to get inside the head of a christian psychologist? Now you can explore the CAT scan images of a psychologist’s head courtesy of yours truly. Consider offering diagnoses and explanations as to how such an mind might work.

These images were taken to rule other matters that might be causing sinusitis. I found looking at my head both nerve wracking AND exciting at the same time.

Conclusion: Negative sinusitis. Nothing missing of note.
