Evidence of Consciousness Surviving the Body One of the most common criticisms aimed at near death experiences, is that they are hallucinations. Michael Shermer in a 2013 article in the Scientific American postulates that these experiences can be attributed to hallucinations. The question is then, is this likely the case, not is it possible, but is it likely that these cases are hallucinations? Since we cannot get a definitive answer, that is, an answer in absolute terms, our conclusion should give us an answer as to the likelihood of one conclusion over another. So, the question boils down to whether a hallucination is as good or a better explanation of what is happening, than the explanation that these are veridical perceptions. Moreover, the question is not, “Are these real experiences?” Why? Because any experience is real, even a hallucination, but we want to ask if the experience is as real or more real than our everyday experiences, which is why we want to know if the experience is veridical.
The question we should ask first, is, what is a hallucination? Hallucinations are sensory perceptions that a person experiences without external stimulus. In other words, the experience is purely subjective and only exists in their mind, as opposed to objectively verified experiences. Hallucinations can occur in any sensory modality (hearing, seeing, taste, tactile, or smell). Hallucinations are not veridical, which is why they are called hallucinations. They are distortions of reality, and they are usually associated with illnesses like schizophrenia or bipolar disorder.
What distinguishes veridical experiences from hallucinations? A veridical experience has an objective component that is shared with others, that is, we generally see (feel, taste, hear, and smell) the same things, we have shared external stimuli, which is what makes a normal sensory experience.
If NDEs are hallucinations, then why are so many people seeing the same things, at least generally? Moreover, if these experiences are not veridical, then why do so many doctors, nurses, family members, and friends verify the accuracy of the experience. In other words, those who are not having the experience corroborate the testimonial accuracy of the one’s having the NDE. This is not the case with hallucinations, that is, others, who are at the scene of the hallucination do not report that the hallucination is an account of objective reality. Hallucinations are not corroborated.
Many people who have an NDE describe their experience as hyper-real, that is, more real than real. When they compare their normal every day experiences to their NDE, their normal reality seems dreamlike by comparison. They describe their sensory experiences as expanded. For example, the ability to see what is happening in a more expanded field of vision, or seeing colors that they have never seen before. These are not the kind of reports that are associated with hallucinations, nor are they the reports of those whose brains are shutting down, or that lack oxygen, or that are the result of medication.
Why do so many people say that NDEs are hallucinations? There are many reasons. First, they are just giving their opinion. Second, these experiences (NDEs) do not fit their world view. Third, most or many people who have beliefs that are strictly materialistic are biased, and this is true no matter their education. Fourth, they have not studied NDEs, so they are just not sufficiently knowledgeable on the subject, again just giving their opinion based on what they think they know.
So, the objection that NDEs are hallucinations is just not a viable argument. Neither is it a viable argument that NDEs are random firings of a brain that is shutting down. Other criticisms of NDEs are equally lacking in evidence, such as, a lack of oxygen to the brain, delusions, dreams, or some other brain malfunction.
The most likely conclusion based on the evidence, is that these cases are not hallucinations, and that it is more likely than not, that they are veridical experiences.
