Sensing the Departed: Understanding ‘Sense of Presence’ Experiences

As the holiday season approaches, many individuals experience a heightened awareness of both connection and absence, particularly when it comes to loved ones who have passed away. This phenomenon, often characterized by a fleeting sense of the deceased’s presence, has been scientifically termed “sense of presence” experiences. These moments can manifest in various ways, such as a familiar scent, a brief visual impression, or a comforting touch, bringing comfort to those who are grieving.

Research indicates that these experiences are more widespread than commonly assumed. According to a review published in 2020, between 47 percent and 82 percent of bereaved individuals reported having sensed the presence of a deceased loved one. The accounts vary but often reflect a deep emotional connection rather than spiritual beliefs. One participant recounted feeling a deceased relative’s arm around her shoulders during a solitary meal, while another described the comforting smell of cigar smoke associated with his grandfather.

Exploring the Emotional Landscape of Grief

A significant study conducted by psychiatrist William Dewi Rees in 1971 found that nearly 40 percent of widowed individuals in Wales reported sensing their deceased spouses. Rees’s pioneering work in bereavement research challenged prevailing notions that framed such experiences as pathological or purely hallucinatory. Instead, he argued for their commonality and comforting nature among the bereaved.

Despite these findings, the mental health community has historically struggled with integrating the concept of a sense of presence into mainstream understanding. Many professionals viewed these experiences through a lens of skepticism, often attributing them to hallucinations or spiritual phenomena. This perspective shifted with the introduction of the Continuing Bonds Theory in the 1990s, as articulated in the influential book “Continuing Bonds: New Understandings of Grief” by Dennis Klass, Phyllis Silverman, and Steven Nickman. This framework posits that such experiences are a natural extension of the ongoing relationship with the deceased rather than indicators of pathology.

Current research, including ongoing studies by PhD candidates, is delving deeper into the neurological underpinnings of these phenomena. Investigations are focusing on how the brain constructs and maintains personal networks associated with significant relationships. These networks encompass memories, emotions, and social perceptions tied to individuals who have played important roles in our lives.

The Brain’s Adaptation to Loss

When someone close passes away, the brain does not instantly adjust to this absence. Instead, it engages in a gradual process of adaptation, aiming to sustain its emotional and psychological bonds with the deceased. This adjustment does not signify denial but reflects a deep-seated effort to redefine the relationship in light of the loss. For many, this re-evaluation is particularly poignant during the holiday season, a time often marked by gatherings and family ties.

The sense of presence is viewed as a momentary expression of this internal adjustment. It represents how one’s mental model of the deceased may influence perceptions in everyday life. This theory distinguishes grief-related presences from neurological phenomena such as autoscopic hallucinations or other disorders, which often feel disorienting and unfamiliar. In contrast, the sensations associated with grief are typically recognized as belonging to the lost loved one, highlighting the enduring bonds of attachment and memory.

To further investigate these experiences, researchers are conducting studies utilizing electroencephalograms (EEGs) to measure brain activity in response to different relationships within an individual’s social circle. Preliminary findings suggest that each significant relationship activates its unique neural network, providing a potential explanation for why some individuals continue to experience a sense of presence long after their loved ones have passed.

Understanding these complex interactions between memory, attachment, and the brain can illuminate the essential role that such experiences play in the grieving process. By openly discussing and exploring these moments, particularly during a season that emphasizes connection, individuals may find solace in their shared experiences of loss. Ultimately, the ongoing study of sense of presence experiences may enhance our understanding of how we maintain meaningful relationships with those who are no longer physically present.
