Grieving Through Presence: How Science Explains Sensing the Deceased

As the festive season approaches, many individuals experience heightened emotions related to grief, particularly when reflecting on loved ones who are no longer present. This phenomenon, often described as a “sense of presence,” involves fleeting impressions that suggest the deceased may still be nearby. These experiences can include familiar scents, visual apparitions, or even a comforting touch. Understanding the psychological and neurological underpinnings of these sensations can provide insight into the grieving process.

Research indicates that a significant number of bereaved individuals report sensing the presence of loved ones. A review published in 2020 revealed that between 47 percent and 82 percent of those who have lost someone close experienced such phenomena. Reports in the scientific literature illustrate that these experiences are not isolated occurrences. For instance, one individual described feeling a loved one’s embrace while seated alone at a dining table. Another recalled the comforting scent of cigar smoke that reminded them of their grandfather.

The emotional connection to the deceased plays a critical role in these experiences. A recent study conducted as part of a PhD research project involved interviews with 26 bereaved individuals across New Zealand, Australia, Canada, and the United States. Participants reported that their sense of presence was most strongly correlated with the emotional closeness of their relationship, rather than with spiritual beliefs or cultural backgrounds. Many described these moments occurring during times of emotional need or in locations associated with the deceased.

Research conducted by psychiatrist William Dewi Rees in 1971 laid the groundwork for understanding these experiences. In his study of 293 widowed individuals in Wales, he found that nearly 40 percent reported sensing their deceased spouses. This pioneering work highlighted the notion that such experiences are common and often comforting, though they were historically dismissed by some in the psychiatric community as hallucinations or supernatural occurrences.

A significant shift in the understanding of these phenomena arose with the development of the Continuing Bonds Theory in the 1990s, as articulated in the book *Continuing Bonds: New Understandings of Grief* by Dennis Klass, Phyllis Silverman, and Steven Nickman. This framework posits that a sense of presence is not pathological but rather indicative of a bereaved person’s ongoing emotional connection with the deceased.

Current research seeks to delve deeper into the neurological processes behind these experiences. Early findings suggest that the brain maintains a complex “person network” that encompasses memories, emotions, and social perceptions related to significant individuals. When a loved one passes away, the brain does not immediately update this network. Instead, it undergoes a gradual process of adaptation, allowing individuals to maintain an inner relationship with the deceased even after physical separation.

Understanding the mechanics behind a sense of presence may also differentiate it from other neurological phenomena, such as autoscopic hallucinations, which can occur in specific medical conditions. Grief-related presences are typically recognized as familiar and comforting, while neurological hallucinations may feel disorienting or alien.

To further explore these concepts, ongoing research includes an electroencephalogram (EEG) study measuring brain activity in response to various social stimuli. Early results indicate that each relationship may activate a distinct neural network, shedding light on why some individuals continue to feel a loved one’s presence after their passing.

By examining the experiences of sensing the deceased more closely and discussing them openly, researchers hope to enhance understanding of a common aspect of grief, particularly during a season that emphasizes connection and remembrance. Understanding these moments may offer solace to those navigating the complexities of loss and highlight the enduring bonds that remain, even in the absence of physical presence.
