Altered states of consciousness (ASC) encompass phenomena such as near-death experiences (NDEs). NDEs are concise accounts of individuals who have undergone clinical death and subsequently been spontaneously resuscitated or revived, retaining recollection of their experiences during that interval. Numerous individuals who have undergone near-death experiences have recounted experiencing intense mental lucidity, extraordinary sensory images, and a distinct recollection of the event that surpasses the realism of their ordinary existence. The Quantum Hologram Theory of Physics and Consciousness (QHTC) elucidates the fundamental characteristics of our existence and the quantum properties of the human mind. QHTC proposes that the brain functions in a manner akin to a hologram, adhering to quantum principles. The QHTC proposes that during an ASC, cognitive processes accelerate and there is an enhanced level of perceptual lucidity. Natural language processing (NLP) refers to a collection of computer methods used to analyze and represent texts that occur naturally. Ontology is a firmly established theoretical field in the philosophy of language that focuses on conceptual frameworks for understanding reality. This study employs NLP to extract linguistic sequences from NDEs narratives stored in a database including 4267 records. It then utilizes ontology research approaches to establish a mapping between the QHTC ontology and human language. The research aims to verify some ontological components of the QHTC, including the notion that during ASC, cognitive processes accelerate and there is an enhanced level of perceptual lucidity.
