J. Steve Miller devoted his work to a phenomenon that fifty years ago was ignored by the scientific community or perceived as a mental disorder. In our time, a huge amount of material has been accumulated on this topic, which in the specialized literature is called the experience of dying, clinical death or near-death experiences (NDEs) and which poses the inevitable questions: “Is there life after death?
