Book Review: After the Light: What I Discovered on the Other Side of Life That Can Change Your World

In 1997, Greyson reviewed Kimberly Clark Sharp’s memoir After the Light, a first-person account of a near-death experience and its transformative effects. The review exemplifies Greyson’s approach to NDE literature: rigorous yet compassionate, balancing clinical skepticism with recognition of the profound impact these experiences have on those who undergo them.

Key findings

  • Sharp’s memoir combines personal NDE narrative with clinical expertise as a critical care social worker, lending credibility to accounts that might otherwise be dismissed as merely anecdotal.1
  • The book opens not with Sharp’s own experience but with the case of Maria, a migrant worker whose out-of-body perception of a tennis shoe on a hospital window ledge represents a striking example of veridical perception during cardiac arrest.1
  • Greyson endorses Sharp’s clinical approach of validating NDErs’ experiences as real while remaining agnostic about metaphysical claims, recognizing the therapeutic value of such validation.1
  • The book’s strength lies in its balance: Sharp avoids imposing either a Christian theological interpretation or a reductionist medical explanation (such as “ICU psychosis”) on the experiences she documents.1
  • Sharp’s wit and down-to-earth style make accounts of spiritual and anomalous phenomena accessible and difficult to dismiss, despite their extraordinary nature.1

Overview

Greyson’s 1997 review of After the Light addresses a question that might seem rhetorical: with so many first-person NDE accounts already published, do we need another one?1 His answer is unequivocal, we can never have too many. Yet he immediately clarifies that Sharp’s book is not merely another autobiographical NDE story. What distinguishes it is the author’s dual perspective: she writes both as someone who has undergone a transformative near-death experience and as a trained clinical care social worker with professional expertise in medical settings and patient psychology.

The book emerged from Sharp’s long involvement with the International Association for Near-Death Studies (IANDS), where she served as the Northwest Regional Coordinator and, for many years, coordinated the Seattle Friends of IANDS chapter, described as the oldest and largest local affiliate of its kind.1 This dual role (both experiencer and professional advocate) shapes the entire narrative and gives it an authority that pure memoir or pure clinical analysis alone could not achieve.

Sharp’s Account and Clinical Expertise

Greyson emphasizes that Sharp brings to her NDE narrative “her clinical expertise as a critical care social worker and her earthy humor.”1 The book contains what Sharp herself calls “woo-woo” experiences, spiritual and anomalous phenomena that might ordinarily invite skepticism or dismissal. However, Sharp’s writing style and her willingness to acknowledge the extraordinary nature of her material (even with humor) make these accounts difficult to dismiss outright. Greyson notes that Sharp alludes to her “secret persona” as a stand-up comic, and this comedic sensibility permeates the book, lending it an accessibility that prevents it from becoming either preachy or overly credulous.

Importantly, Sharp does not impose a single interpretive framework on the experiences she describes. While she herself maintains a traditional Christian orientation and references angelic and divine intervention in her own experiences, she does not insist that only Christians are saved, nor does she impose her theological interpretation on the NDEs of her patients.1 Instead, she takes each experience at face value and allows the experiencer to formulate their own understanding. This clinical restraint (the refusal to pathologize or to over-interpret) is precisely what Greyson, as both scientist and clinician, finds valuable.

Validation and Clinical Utility

A central theme in Greyson’s review is the therapeutic power of validation. Sharp’s fundamental message to her patients is straightforward: “What you experienced is real.”1 Greyson acknowledges the tension this creates for a scientist. As a researcher, he notes, he cannot be certain that every NDEr’s experience is literally real in an ontological sense. However, as a clinician, he is “quite certain” that validating the sanity and reality of an NDEr’s experience is helpful and therapeutic.1

This distinction (between metaphysical truth and clinical utility) is crucial to understanding Greyson’s approach to NDE literature and research. Sharp’s refusal to impose either a medical reductionist interpretation (dismissing the experience as “ICU psychosis”) or an exclusively theological one allows her patients to maintain their dignity and autonomy in making sense of their own experiences. The book models a clinical stance that respects both scientific rigor and the lived reality of the experiencer.

The Maria Case: Veridical Perception

Greyson devotes particular attention to the case of Maria, which Sharp places at the beginning of her book rather than burying it in a later chapter. Maria was a migrant worker admitted to Harborview Medical Center’s cardiac care unit, where Sharp was working as a social worker. During cardiac arrest, Maria’s consciousness appeared to leave her body and travel to a third-story window ledge on the side of the hospital farthest from the cardiac care unit. There, Maria perceived “a man’s dark blue tennis shoe, well-worn, scuffed on the left side where the little toe would go. The shoelace was caught under the heel.”1

What makes this case significant is not merely the perception itself but Sharp’s subsequent verification. Despite her own NDE background, Sharp’s professional training initially led her to doubt Maria’s account. However, she eventually located the shoe by going from room to room and pressing her face against windows, and crucially, the scuffed toe could only be seen from a perspective outside and above the window, exactly as Maria had described it.1 This case of apparent veridical perception during unconsciousness is one of the most compelling in NDE literature, and Greyson notes that Sharp’s detailed account here is the definitive version of the “Maria’s tennis shoe” story, having been published previously in his own 1984 NDE anthology and cited by other researchers including Susan Blackmore.

By opening her book with this case rather than her own NDE, Sharp establishes credibility and demonstrates that the phenomena she is describing are not merely subjective or psychological but may involve genuine perception of external facts. This strategic placement underscores the book’s central claim: that NDEs warrant serious attention not as mere hallucinations or fantasies but as experiences that may reveal something about consciousness and reality.

Greyson’s Assessment

Greyson’s overall assessment is decidedly positive. He recognizes that After the Light succeeds in what it sets out to do: provide a compassionate, clinically informed, and accessible account of near-death experience and its aftermath. The book does not attempt to prove the existence of an afterlife or to convert readers to a particular religious worldview. Instead, it documents the profound changes that NDEs produce in those who experience them and offers practical guidance for integrating these experiences into daily life.

The review reflects Greyson’s broader conviction that first-person NDE narratives, when written with honesty and clinical awareness, constitute valuable data for understanding consciousness, spirituality, and human resilience. Sharp’s combination of personal testimony, clinical expertise, and willingness to engage with both the extraordinary and the mundane aspects of NDE aftereffects makes After the Light a significant contribution to NDE literature. For Greyson, the book exemplifies how rigorous thinking and openness to anomalous phenomena need not be mutually exclusive, a principle that has guided his own four decades of NDE research and his leadership of the Division of Perceptual Studies at the University of Virginia.
