I have personally investigated and interviewed people with near-death experience. What they described to me perfectly matched what their doctors saw at the time. More importantly, their experience with near-death has caused tremendous change in their view on life and values.

I knew a teacher who had near-death experience. After he came back to life, he dedicated all his time and effort to promoting one idea: Do not move or do anything to the body immediately after the person appears to be dead because at this moment the person is still alive; the soul is still with him or her.

Except for accidental death, Buddhist texts usually describe the process of a normal death this way: First, the eyes, ears and other organs will gradually stop functioning. When they are about to stop, one can no longer recognize even the most familiar faces; voices from people around become dim, as if coming from afar; body feels like sinking down in the period leading up to death, although it is impossible to sink when lying on bed. All these just indicate that the organs are about to stop working and life will soon end.
