Near-Death Experiences (NDEs)
By Dr. Hilmar Alquiros, Philippines
Where is the color red in my brain...??
"We must confess that perception, and what depends upon it,
is inexplicable in terms of mechanical reasons,
that is through shapes, size, and motions.
If we imagine a machine whose structure makes it think, sense, and have perceptions,
we could conceive it enlarged, keeping the same proportions,
so that we could enter into it, as one enters a mill.
Assuming that, when inspecting its interior, we will find only parts that push one another,
and we will never find anything to explain a perception.
And so, one should seek perception in the simple substance and not in the composite or in the machine."
German philosopher, mathematician, historian, lawyer... Gottfried Wilhelm LEIBNIZ (1646-1716) ("Last universal genius")

c. Long-Term Effects
Near-Death Experiences (NDEs) have long been a subject of fascination and intrigue, captivating the minds of scientists, theologians, and laypeople alike. These profound experiences, often described as ethereal or otherworldly, occur at the precipice of life and death, making them both awe-inspiring and enigmatic.
Historically, narratives of experiences echoing contemporary NDE accounts can be found in ancient scriptures, literary texts, and oral traditions, suggesting that they might be an intrinsic part of human existence. These narratives, while separated by time and culture, consistently recount elements such as the sensation of floating, moving through a tunnel, encountering luminous entities, or a panoramic life review. Particularly intriguing are instances of veridical perception, where individuals, despite being unconscious or even clinically dead, report observing events or intricate details which are later corroborated.
The interpretations of NDEs are as varied as the experiences themselves. From a neurological standpoint, some scientists believe that the dying brain, under duress, releases a cascade of neurotransmitters, possibly explaining the vivid hallucinations. The effects of oxygen deprivation, leading to tunnel vision or bright flashes, could further elucidate certain common elements of NDEs. Psychologists might argue that these experiences serve a protective function, creating a mental buffer against the distressing process of dying. Meanwhile, many individuals and spiritual leaders see NDEs in a transcendent light, interpreting them as a testament to an afterlife, divine encounters, or journeys to alternate realms of consciousness.
The aftermath of an NDE is often as compelling as the experience itself. A brush with the beyond can dramatically shift an individual's perspective, leading to a more profound appreciation for life, altered priorities, or spiritual awakenings. However, this transformation can also be disorienting. The challenge of articulating such an ineffable experience or the feeling of being out of sync with one's prior beliefs and community can lead to feelings of alienation. Recognizing the depth and complexity of these experiences, several support groups and platforms have emerged, offering a sanctuary for NDE experiencers to share, reflect, and find mutual understanding.
In the grand tapestry of human experiences, NDEs are a testament to the mysteries of consciousness and existence. As research continues and more narratives emerge, they offer a unique window into the interplay of the brain, the psyche, and possibly, the soul.
a. Near-Death Experiences (NDEs):
Historical Context: Throughout history, there have been records of experiences that align with modern descriptions of NDEs, indicating that such phenomena might be a consistent part of the human experience.
Common Elements: While the exact details can vary, many NDEs share similar elements, such as a bright light, feelings of unconditional love, and a life review where one sees significant life events play out.
Veridical Perception: In some cases, individuals have perceived events or details while seemingly unconscious or clinically dead, which they could later verify as accurate!
b. Interpretations:
Neuroscientific Explanations: Some researchers suggest that NDEs result from the brain's response to extreme stress. The release of neurotransmitters like glutamate can cause hallucinations, while oxygen deprivation can result in a tunnel vision effect.
Psychological Perspectives: NDEs might represent a protective psychological mechanism, distancing the individual from the traumatic experience of dying.
Cultural Variations: It's worth noting that while there are commonalities in NDEs globally, cultural differences do exist. For instance, the specific entities or beings encountered during an NDE may align with a person's cultural or religious beliefs.
While the provided search results do not offer specific examples of NDE reports, it's widely known from various studies and anecdotal accounts that some individuals who have experienced Near-Death Experiences (NDEs) have witnessed events or gleaned information during periods when they were clinically dead. These reports are especially compelling when the details they provide are later verified by others. Here are some commonly cited types of accounts:
Spiritual and Transcendent Views: For many, NDEs hold spiritual significance. They might interpret the experience as a glimpse into the afterlife, a meeting with a higher power, or a journey into another dimension of consciousness.
Out-of-Body Observations: Some individuals report floating above their bodies during medical procedures and are sometimes able to describe specific details about their surroundings or the actions of medical personnel that they wouldn't have been able to perceive from their physical position.
Hearing Conversations: There are accounts of individuals overhearing conversations between medical staff or loved ones while they were unconscious or clinically dead. In some cases, the content of these conversations was later confirmed by the people involved.
Encounters with Deceased Loved Ones: Some report meeting deceased family members or friends and receiving messages or information from them that they previously didn't know, which are later verified as accurate.
Observations of Distant Events: A few NDE reports include descriptions of events happening at distant locations (e.g., a relative in another room or even another building) which are later confirmed to have occurred at the same time as the NDE.
c. Long-Term Effects:
Transformational Change: Many who experience NDEs describe them as life-altering. This transformative effect often results in a more profound sense of purpose and a reevaluation of life priorities.
Challenges: Reintegrating into everyday life after an NDE can be challenging. Some individuals might struggle with feelings of isolation, especially if they feel misunderstood or unsupported by their community.
Affiliation with Support Groups: Given the unique and profound nature of their experiences, some individuals seek out NDE support groups or forums, finding solace and understanding among others who have undergone similar experiences.
Overall, NDEs represent a fascinating intersection of psychology, neuroscience, spirituality, and philosophy. While science may one day offer more comprehensive explanations for the phenomena, the deeply personal and transformative nature of NDEs ensures that they will remain a topic of curiosity and wonder.

e. New Interpretations: Anti-monistic Materialism, Analytic Idealism
a. New Research:
Recent studies on Near-Death Experiences (NDEs) have been conducted worldwide, involving thousands of cases monitored with ECG and EEG, even during flatline brain activity. Reports of "terminal lucidity" in dementia patients, where individuals suddenly regain clear speech before death, challenge materialistic views by suggesting a potential non-physical aspect of consciousness. Verified out-of-body experiences (OBEs) during deep meditation indicate that consciousness might operate independently of the physical body. Additionally, NDE accounts of meeting recently deceased individuals with specific, previously unknown information further support the notion of a non-material realm of consciousness. These verified perceptions, documented and corroborated by medical personnel, challenge the materialistic view that consciousness is solely a product of brain activity, suggesting the need for new frameworks to understand these phenomena.
More researchers in many countries with better controlled Main NDE Experiences (ECG, EEG, flatline brain activity): with thousands of examples, reported in books by famous scientists and in internet collections. Specific literature and links at the end as 20.3.
Clear Speech in Dementia Patients Before Death: There are numerous anecdotal reports of dementia patients, who typically exhibit severe cognitive impairment, suddenly speaking clearly and coherently in their final hours or days. This phenomenon, often referred to as "terminal lucidity," is difficult to explain within the framework of materialistic neuroscience, as it suggests a temporary restoration of cognitive functions that were believed to be irreversibly damaged. This phenomenon of Terminal Lucidity suggests that consciousness might not be entirely dependent on the physical state of the brain. The sudden clarity observed in terminal lucidity implies that there could be an underlying aspect of consciousness that remains intact despite severe brain damage.
Out-of-Body Experiences in Deep Meditation: Many individuals report having out-of-body experiences (OBEs) during deep meditation, where they perceive themselves as existing outside their physical bodies. These experiences often include detailed observations of their surroundings or even distant locations, which they can later verify. Such phenomena suggest that consciousness can operate independently of the physical body. The ability of individuals to have verifiable perceptions during OBEs in meditation indicates that consciousness might extend beyond the physical confines of the brain. This challenges the materialistic view and supports the idea of a non-material aspect of consciousness.
Meeting Recently Deceased Individuals: In some NDE reports, individuals describe meeting people who had died recently, often without their prior knowledge of the death. These encounters provide specific information that the individuals could not have known, further challenging the notion that these experiences are purely hallucinatory or brain-generated. Meeting recently deceased individuals during NDEs and gaining information that was not previously known supports the notion of consciousness existing in a non-material realm. These experiences are difficult to explain through traditional materialistic theories.
Verified Perceptions as Evidence
The verified perceptions, the Crown witness of brain-independent consciousness, reported by clinically dead individuals are documented and corroborated by medical personnel and others present. These accounts challenge the materialistic view that consciousness is solely a product of brain activity. The consistency of these experiences across different cultures and contexts, as well as their verifiability, strengthens the case for considering them as genuine phenomena that require an explanation beyond traditional materialistic frameworks.
Some well-documented examples:
Pam Reynolds, an American singer, underwent a rare surgical procedure in 1991 to remove a brain aneurysm. During the surgery, her body temperature was lowered, her heartbeat and breathing stopped, and her brain activity ceased, essentially putting her in a state of clinical death. Despite this, she later recounted detailed observations of the surgical procedure, including specific instruments and conversations that were later verified by the medical team present.

In this famous case, a patient named Maria reported an out-of-body experience during her cardiac arrest, during which she observed a tennis shoe on a ledge outside a hospital window.

b. Classic Interpretations:
Classic interpretations often attribute Near-Death Experiences (NDEs) and Out-of-Body Experiences (OBEs) to oxygen deprivation (hypoxia), hallucinations, or drug effects. However, hypoxia typically leads to confusion and disorientation, unlike the clear and coherent experiences of NDEs. The consistency of OBE reports across cultures and the inclusion of verifiable information during clinical death challenge the hypoxia theory. Hallucinations, usually fragmented and requiring brain activity, do not explain the detailed, structured, and verifiable experiences reported during NDEs with flat EEG readings. Drug-induced experiences vary widely and lack the common elements seen in NDEs, with studies showing similar NDEs regardless of drug use, making it unlikely that drugs are the primary cause. These classic explanations struggle to account for the detailed, consistent, and verifiable nature of NDEs and OBEs.
Oxygen deprivation (hypoxia) is often cited as a cause of vivid hallucinations and altered states of consciousness during OBEs.
Duration and Clarity: Hypoxia typically leads to confusion, disorientation, and impaired cognitive function. In contrast, NDEs and OBEs often involve clear, vivid, and coherent experiences that are more intense than normal consciousness.
Consistency of Reports: The detailed and consistent nature of OBE reports across different cultures and individuals suggests a common underlying experience rather than random hallucinations caused by lack of oxygen.
Verifiable Information: Many OBE reports include verifiable information about events or conversations that occurred while the person was clinically dead, which cannot be explained by hypoxia-induced hallucinations.
Hallucinations: Hallucinations, whether due to psychological factors, drugs, or other causes, are often proposed as explanations for NDEs and OBEs.
Nature of Hallucinations: Hallucinations are typically fragmented, disjointed, and lack the coherent, structured narratives found in NDEs and OBEs.
Lack of External Stimuli: Hallucinations generally require some form of brain activity. In cases of clinical death with flat EEG readings, there is no brain activity to generate these experiences.
Verifiable Details: Hallucinatory experiences do not typically include accurate, verifiable details about external events or environments, which are frequently reported in OBEs.
Drug Effects: The use of drugs or anesthesia during medical procedures is sometimes suggested as a cause of NDEs and OBEs.
Specificity of Experience: Drug-induced experiences vary widely and are often dependent on the type of drug used. In contrast, NDEs and OBEs share many common elements regardless of the individual's background or medical treatment.
Controlled Studies: Studies have shown that individuals who have NDEs while not under the influence of drugs report experiences similar to those who are under anesthesia, suggesting that drugs are not the primary cause.
Flat Brain Function: During clinical death, the brain shows no measurable activity, making it implausible for drugs to induce such detailed and coherent experiences
c. Non-existence of Consciousness
The claim that consciousness does not exist or is merely an illusion is a radical and counterintuitive stance, contradicting our everyday experiences of thoughts, feelings, and perceptions. Materialistic monism posits that consciousness can be entirely explained by neural processes in the brain, leading to the idea that our conscious experiences are just elaborate brain-generated illusions.
Philosophers like Daniel Dennett and proponents of eliminative materialism, such as Paul and Patricia Churchland, support this view, suggesting that neuroscience will eventually explain away the need for concepts like "beliefs" or "desires." Critics argue that subjective experiences, or qualia, are real and fundamental aspects of being, challenging the illusion claim. David Chalmers’ Hard Problem of Consciousness highlights the difficulty in explaining subjective experiences through physical processes alone, pointing out the limitations of materialistic monism.
This stance is seen as a desperate attempt to preserve materialistic views amidst evidence from NDEs, terminal lucidity, and OBEs suggesting that consciousness might exist independently of the brain. Accepting consciousness as an illusion could undermine the understanding of subjective experiences and dismiss significant phenomena indicating non-material aspects of consciousness.
Radical Nature: The idea that consciousness is an illusion
contradicts our everyday experiences. Consciousness is the most
direct and undeniable aspect of our existence; we are aware of our
thoughts, feelings, and perceptions.
Materialistic Monism: Materialistic monism posits that everything, including consciousness, can be explained by physical processes in the brain. This view often leads to the assertion that what we experience as consciousness is merely the result of neural activity and not an entity in itself.
Philosophical Arguments: Philosopher Daniel Dennett, in his book "Consciousness Explained," argues that what we perceive as conscious experience is an elaborate trick played by our brain. He suggests that consciousness is a user-illusion created by complex brain functions. Some proponents of eliminative materialism, like Paul and Patricia Churchland, argue that common-sense understandings of the mind are false and that neuroscience will eventually provide explanations that eliminate the need for concepts like "beliefs" or "desires."
Counterarguments: Direct Experience: Critics argue that conscious experience is the most fundamental aspect of being and cannot be dismissed as an illusion. They point out that our subjective experiences, or qualia, are real and directly known to us. David Chalmers’ Hard Problem of Consciousness highlights the difficulty in explaining why and how physical processes in the brain give rise to subjective experiences. This problem underscores the limitations of materialistic monism in fully accounting for consciousness.
Desperate Attempt: The assertion that consciousness is an illusion is often seen as a desperate attempt to preserve materialistic monism in light of growing evidence suggesting that consciousness might not be fully explainable by physical processes alone. This stance is increasingly challenged by findings in NDE research, terminal lucidity, and OBEs, which suggest that consciousness can exist independently of brain activity.
Scientific and Philosophical Implications: Accepting consciousness as an illusion could undermine the pursuit of understanding subjective experiences. It may also dismiss significant phenomena that point to the possibility of non-material aspects of consciousness.
d. Undiscovered Mechanisms:
Monistic materialism asserts that all phenomena, including consciousness, can be explained by physical brain processes. When faced with challenging phenomena like near-death experiences (NDEs), terminal lucidity, and out-of-body experiences (OBEs), proponents argue that future discoveries will reveal the necessary physical mechanisms. This argument is speculative, lacking current empirical evidence and serving as a placeholder to uphold the materialistic framework.
Critics highlight the absence of evidence for these hypothetical mechanisms and point to David Chalmers’ Hard Problem of Consciousness, which underscores the difficulty of explaining subjective experiences through physical processes alone. Evidence from NDEs, terminal lucidity, and OBEs suggests consciousness might not be fully explainable by physical means. Philosophical perspectives like dualism and analytic idealism propose that consciousness is a non-material entity or the fundamental aspect of reality, offering coherent explanations for these challenging phenomena.
Speculative Nature: This argument is speculative because it relies on the assumption that all aspects of consciousness are physical and that the necessary discoveries are simply yet to be made. There is no current empirical evidence supporting these hypothetical mechanisms. It is a way to maintain the materialistic framework without addressing the current evidence that contradicts it, keeping Challenges and Counterarguments as:
Lack of Evidence: The claim of undiscovered mechanisms lacks empirical evidence. It is a placeholder rather than a substantive explanation, postponing the resolution of the problem indefinitely.
Hard Problem of Consciousness: David Chalmers’ Hard Problem of Consciousness emphasizes the difficulty of explaining why and how subjective experiences (Qualia) arise from physical brain processes. This challenge remains unresolved and suggests that consciousness might not be fully explainable by physical mechanisms alone.
Existing Evidence from NDEs and Other Phenomena: Near-Death Experiences (NDEs), Terminal Lucidity and Out-of-Body Experiences (OBEs).
Philosophical Implications: Dualistic interpretations propose that consciousness is a non-material entity that interacts with the physical brain but is not reducible to it. This view is directly supported by the evidence from NDEs, terminal lucidity, and OBEs. Analytic Idealism view posits that consciousness is the fundamental aspect of reality, and the material world is a manifestation of consciousness. This perspective provides a coherent framework for understanding the phenomena that challenge materialistic explanations.
e. The 'Hard core Solution' of Consciousness
The Hard Problem of Consciousness, articulated by philosopher David Chalmers, refers to the challenge of explaining why and how subjective experiences, or qualia, arise from physical processes in the brain. Unlike "easy" problems, which involve understanding cognitive functions and behaviors, the Hard Problem addresses the essence of consciousness itself. It questions how physical brain activities translate into the rich, inner experiences of awareness and perception. This problem remains unresolved, as current scientific methods struggle to bridge the gap between objective neural processes and subjective conscious experience, highlighting a fundamental mystery at the heart of human cognition.
New empirical results, especially verified perceptions during NDEs with controlled flatline brain activity, critique monistic materialism. While this framework is effective for studying the physical world, it falls short in explaining subjective experiences and consciousness. Consequently, new assumptions about non-material "spiritual" phenomena have emerged.
Anti-monistic Materialism: This perspective challenges the idea that reality is solely constituted by physical matter. It argues that consciousness and subjective experiences cannot be fully understood through materialistic explanations alone. Advocates highlight the limitations of reductionism in addressing the complexities of mind and consciousness, suggesting that non-material elements or dualistic frameworks might be necessary to explain the full spectrum of reality. This viewpoint opens the door to exploring consciousness beyond purely physical theories.
Analytic Idealism: Analytic Idealism posits that consciousness is the foundational aspect of reality. It argues that the material world is a manifestation of consciousness, not the other way around. In contrast to materialism, which sees the mind as a product of physical processes, Analytic Idealism holds that physical phenomena emerge from conscious experiences. Proponents use rigorous, logical analysis to support the idea that consciousness is primary and fundamental. This approach challenges traditional physicalist perspectives, suggesting that understanding the nature of consciousness is key to understanding the nature of reality itself.
