“The past is never dead, not even the past.”
William Faulkner
In clinical practice, there are times when someone describes anxiety, insomnia, depression, or a constant sense of dread, but nothing in their current life fully explains it. They have a supportive relationship. Their work is normal. They treated. They understand and to some extent have made peace with their childhood. And yet, something in the body remains awake.
What if some of the things we carry didn’t start with us?
Increasingly, research and systemic approaches show that trauma is not only psychological. It is biological. It is a relationship. It can be passed down through generations, shaping stress responses, emotional patterns, and even our sense of identity.
The question is not whether the past influences us. It does. The deeper question is how.
Trauma does not end with a person
Trauma occurs when an experience overwhelms the nervous system’s ability to integrate. War, genocide, forced migration, suicide, early death, abandonment, sudden loss. These events destroy the fabric of family life. When grief can’t be processed or talked about, it just doesn’t go away.
Freud described the repetition compulsion as an unconscious drive to repeat an unresolved experience. Jung observed that what remains unconscious returns as fate. Both pointed to the same phenomenon: that which is not united cannot be resolved. It reappears in behavior, emotions, and relationship patterns.
Families are often silent around painful events. A child has been given. A brother who died young. The grandfather who did not return from the war. Silence itself becomes part of the heritage. What is excluded or unspoken can remain as anxiety without story, grief without story, vigilance without context.
In this way, the injury can echo.
Genetic stress biology
Modern research in epigenetics offers an explanation for how these echoes can move.
Epigenetics refers to changes in gene expression that occur without changing the DNA sequence. Environmental stress, especially chronic or excessive stress, can leave chemical signals in genes that affect the functioning of the stress response system. These changes can affect cortisol regulation, immune function, and emotional reactivity.
Studies of generations of Holocaust survivors, war veterans, and traumatized populations have shown that stress hormone patterns change in subsequent generations. Children and grandchildren may show increased alertness, anxiety, difficulty calming down, or vulnerability to depression, despite not directly experiencing the initial trauma.
This does not mean that we are biologically doomed. These adaptations are designed to increase survival. If your ancestors lived in dangerous conditions, high alertness would have been protective. The nervous system adapts to its intended environment.
It is also important to understand that three generations can share the same biological environment. When a woman is pregnant with a girl, developing eggs that may one day become her grandchildren are already forming in the fetus. In this sense, the effects of stress can affect multiple generations simultaneously.
However, biology can tell the whole story.
Beyond Biology: Morphic Resonance and the Field of Memory
Rupert Sheldrake, a visionary British scientist, proposed a controversial but interesting hypothesis known as morphic resonance. He proposed that systems inherit collective memory not just through genes, but through spheres of influence that connect similar patterns over time.
According to this view, organisms and social systems are shaped by morphic fields, forming patterns that influence behavior, development, and memory. These fields transfer data from previous similar systems. The more the pattern repeats, the stronger the field becomes.
Although morphic resonance is not accepted as mainstream science and remains a hypothesis, it provides a conceptual framework that many systemic clinicians work with. It suggests that families exist within domains of shared relationships that extend beyond individual biographies.
If such fields exist, emotional patterns, loyalties, and unresolved traumas may persist in ways that cannot be fully explained by genetics alone. Recurring family themes, similar intergenerational relationship dynamics, recurring patterns of loss or illness may reflect participation in the realm of shared memory.
Whether understood as biological or relational, the effect is the same. The past remains active within the present.
Signs as echoes
In practice, it can look like anxiety that is bigger than the current life circumstances. Insomnia that begins at the same age, an uncle died. Depression, which sets off a sad tone from current events. Pervasive feelings of being alone, dangerous, or responsible for others without a clear cause.
Sometimes the body remembers something that the mind does not.
These signs are not imaginary. They are a real physiological state. Heart rate changes. Cortisol changes. Muscles become stiff. But the trigger may not be up to date. It can be located in inherited stress reactions or in the wider field of family system relationships.
Obsessed loyalty can play a role. A child may identify with a departed ancestor. A grandchild can carry the emotional burden of a grandmother whose suffering was never acknowledged. The body can become a place where unfinished grief seeks expression.
This is not mystical thinking. This is an observation that is repeated in all therapeutic settings. The characters are sometimes softened as previously hidden family stories are revealed. When the outcast is acknowledged, anxiety can decrease. When sadness is released, the nervous system can calm down.
Working with the Square
Systemic approaches, such as Family Constellations, operate on the understanding that people are placed within spheres of relationships. In this work, family dynamics are spatially mapped to reveal disparate identities and loyalties.
Clients often find that what they thought was purely personal anxiety is intertwined with past family events. By symbolically restoring the estranged family members to their rightful place and acknowledging what has happened, the system can be reorganized.
This process is not about guilt. It’s about order. It recognizes that every member of the family belongs, and when someone is forgotten or rejected, the system can try to make it up to the next generation.
From the perspective of morphic resonance, such work is directly related to the field of relationships. Biologically, it can help regulate stress responses by resolving internal conflicts and reducing chronic anxiety. Both frameworks point to the same outcome: integration.
Healing as integration
Realizing that some aspects of our suffering did not originate with us can be profoundly relieving. It moves the story from a personal flaw to an inherited pattern. It calls for sympathy.
The alert will stop the replay. When disrespectful loyalties are brought to consciousness, we make choices. The nervous system no longer needs to respect the past in order to respect it.
The past may be dead. It can live within our biology and relationships. But it should not define our future.
Healing does not require denying one’s ancestors or blaming one’s parents. It requires something quieter and more difficult: recognition. When what has been silenced is addressed, when what has been removed is restored, the body often responds.
And sometimes, as the system reorganizes, anxiety eases, sleep returns, and the present finally feels like the present.
The past can be heard, but it must not be repeated.
