The people declared clinically dead with no brain function, who see themselves floating over the bed where their body is lying, in what is called the near death experience [it really is death-temporarily] show that the mind of man does not depend entirely on brain function. Then they move swiftly through a dark tunnel toward a light. The light is described as a loving person. They feel themselves fall back into their body. The body comes back to life, etc. They tell the doctors detailed descriptions of what they saw and heard spoken while they were dead with no brain function. These cases are documented. The mind and the soul continues after death. It's the body that dies.
