What our eyes can see is limited. What our mind can imagine is also limited. In most cases people do not believe that things exist unless their eyes have seen. The existence of dualism of both human flesh and spirit or existing life and afterlife seems to be a dubious topic. Most people's belief seems to fall into the category of monism that "there is only one fundamental substance as the basis of reality" (Web Dictionary). That reality is the human body, the materialistic world we see every day with our eyes made of flesh. Or in cases where people cannot decide whether consciousness still exists after the death of the body. However, people with testimonies of near-death experiences do not appear to fall into the category of monism, but dualism. What they experienced in a split second of body and soul, on the border between life and death, is inexplicable. Their personal experience reassured the veracity of consciousness that survives after the death of the body and that there will be an afterlife in addition to the life we ​​see existing on this Earth today. The first story that seems very significant to endorse the existence of dualism is a woman named Rebecca. During her death experience it was proven that she was clinically dead. Clinically dead means that “as far as can be ascertained by clinical examination, the patient is dead. There is no pulse, no respiratory movement and no corneal reflex” (medical dictionary). This means that his heart has stopped beating. Being clinically dead for five minutes, with what she experienced is convincing that there is another life. The conscious mind exists, otherwise if someone is proven to be dead, then there should be the appearance of darkness or the memory of nothingness. He felt a kind of Being in… the middle of the paper… in heaven or hell where certain souls are kept” (Dictionary). Most of these stories published people often feel a sense of peace and love. And they also saw eternal light, heaven, or eternal darkness and fire, hell. They must have some kind of explanation beyond that explained by science. In fact the aforementioned near-death experiences and the case of spirit experience cannot be proven by science. Because science can only approve what exists today in this life. Science is a study of matter, which is a “systematic knowledge of the physical or material world acquired through observation and experimentation” (dictionary). These near-death experiences appear to involve physical phenomena within the brain, however, they cannot be scientifically proven from the physical or material world. So consciousness would still exist far from the body.
