For a multitude of reasons and research I have studied for years what happens when we die. While interviewing all walks of life patients who either work with terminally ill patients, or have had deathbed experiences themselves or have come back from death, such as a cardiac arrest etc. I have learned that the dying often seem to know that they're dying. During the week leading up to death, they begin to talk about a journey they are taking. They ask for their shoes, or their plane tickets or to go home when they are at home. Does this then lead us to think that the dying see this as a trip to somewhere else?.
Some will say this is a side effect of the powerful pain killers they are taking, others say NO! In one major national study (by psychologists Karlis Osis, PhD, and Erlendur Haraldsson, PhD, of the University of Iceland) comparing deathbed experiences in the U.S. and India, the overall majority of patients who were still conscious within an hour of death saw deceased loved ones beckoning or calling to them, whether they were medicated or not.
Let’s talk about seeing "the white light” some say it is like finding your way. A feeling of love and peace. All who experience it, are always changed in a way that they live their lives in a different manner.
There have been millions of studies, and in study after study it is confirmed that around 50 percent of the bereaved sense the presence of lost loved ones, either in the moment of death, or sometime shortly after. Psychiatrists call this "grief hallucinations," the science of such subjective experiences remains poorly understood; certainly, it doesn't explain how we can have them before we know someone has died. This happened to someone I know well. She was at a barbecue and looked across to the porch next door ( her house ) and saw her Uncle smiling at her. She was only 6 and did not fully understand death or even know he had dies a few weeks earlier.
