What our eyes can see is limited. What our minds can imagine is also limited. In usual cases, people don't believe things exist unless their eyes have seen it. The existence of a dualism between human flesh and spirit or between existing life and the afterlife seems to be a doubtful subject. Most people's belief seems to fall into the category of monism that "a single basic substance exists as the foundation of reality" (Web Dictionary). This reality is the human body, the materialistic world that we see every day with our eyes made of flesh. Or in cases where people cannot decide whether consciousness still exists after the body dies. However, people who have reported near-death experiences do not seem to fall into the category of monism, but rather dualism. What they experienced for a fraction of a second of body and soul, on the borders of life and death, is inexplicable. Their personal experience provided reassurance about the veracity of consciousness that survives after the death of the body, and there will be life after death in addition to the life we ​​see existing on this Earth today. The first story that seems very significant in approving the existence of dualism is that of a woman named Rebecca. . During her death experience, she was proven to be clinically dead. Clinically dead means that “as far as clinical examination can confirm, the patient is dead”. There is no pulse, no respiratory movement and no corneal reflex” (medical dictionary). Which means his heart has stopped beating. Having been clinically dead for five minutes, with what she's been through, it's convincing that another life exists. The conscious mind exists, otherwise if it turns out that someone is dead then there should be an appearance of either darkness or remembering nothing. She felt a kind of Being in the middle of a paper... a paradise or a hell where certain souls are kept” (Dictionary). Most of these published stories often felt a sense of peace and love. And they also saw either eternal light – heaven, or eternal darkness and fire – hell. They must have certain types of explanations that are not just explained by science. Because the above near-death experiences and the mind experience case cannot be proven by science. Because science can only approve of what exists today in this life. Science is a study of matter, which is “systematic knowledge of the physical or material world acquired through observation and experimentation” (dictionary). These near-death experiences appear to involve a physical phenomenon inside the brain, but they cannot be scientifically proven by the physical or material world. So consciousness would always exist far from the body.
