Modern science approaches these accounts with healthy skepticism but also growing interest. Psychologists and medical researchers studying NDEs note the consistency of “cleansing” themes. Dr. Bruce Greyson and others have documented that NDEs often include a life review with an empathic dimension (the person feels the impact of their actions on others) which can lead to deep psychological resolution (pmc.ncbi.nlm.nih.govpmc.ncbi.nlm.nih.gov). This has been likened to an accelerated form of moral insight therapy – the mind, in a crisis state, somehow reevaluates and “resets” itself.

While not framed as supernatural, psychologists suggest that the life review and encounter with a loving light can trigger what’s known as a “transformational experience”. The experiencer might release long-held guilt or trauma – essentially a psychological cleansing – which explains why so many NDE survivors exhibit positive personality changes (more empathy, less anxiety, etc.) after recovery (blog.sevenponds.com). Some researchers have even compared NDE aftereffects to the outcomes of extensive meditation or psychedelic therapy, where individuals report a sense of “spiritual purification” or rebirth. The key common denominator is the intense, hyper-real experience of unconditional love and insight, which often leads to emotional healing from past wounds.

Neuroscience, on the other hand, strives to find mechanisms for the “white light” and euphoria reported. Hypotheses include oxygen deprivation causing tunnel vision and euphoria, or the brain releasing endorphins and DMT-like chemicals near death. These might account for sensations of peace or hallucinated light.

However, no purely material explanation has yet adequately explained the veridical perceptions and profound, consistent content of NDEs (blog.sevenponds.comblog.sevenponds.com). From a clinical standpoint, a number of studies (by Dr. Pim van Lommel, Dr. Sam Parnia, and others) have noted that NDEs often result in a therapeutic outcome: patients come back from death’s door remarkably less afraid of dying and often healing from psychological issues like depression or addiction.

Such outcomes have prompted some psychiatrists to call NDEs a form of “spontaneous therapeutic event.” If one views the bright light, life review, etc., as the mind’s last attempt to find meaning, it appears to have an inherent “purge and integrate” function – essentially aligning with the age-old idea of purgation. Even without endorsing a spiritual view, psychologists acknowledge the life review forces a person to confront themselves wholly. As one Quora commentator (in a psychological context) mused,

“The [NDE] life review…feels like it lasts forever” and often involves experiencing a sense of judgment or self-judgment that leads to profound self-forgiveness and renewal.

Some contemporary studies also explore deathbed visions and end-of-life dreams. Hospice research has found patients frequently report visions of deceased loved ones, peaceful landscapes, or cleansing water in the days before death. Patients often say these visions help them release fear or emotional burdens, making them calmer. This suggests a possible built-in psychological mechanism where the brain, in the dying process, generates comforting, cleansing narratives – or, as spiritual caregivers might say, the soul prepares itself by shedding attachments.

Lastly, thanatology (the study of death and dying) has brought together both spiritual and scientific perspectives. Conferences on NDEs include not just doctors but theologians and psychologists discussing how common motifs like “entering the Light” or “undergoing a life review” might be universal to human consciousness. Whether one believes these are true glimpses of an afterlife or not, the pattern of a post-death purification is clearly part of human experience and psychology. It provides a powerful coping schema: the idea that suffering and mistakes can be cleansed after death offers comfort to the dying and bereaved. As a result, even secular therapists sometimes use the language of “healing light” in guided visualizations for patients nearing death, because it resonates deeply and brings peace.
