Also we have all had really vivid dreams and even hallucinations from the effects of medication. Yet even though at the time they seem real, we quickly understand they are not. For those who have had NDEs they become the strongest memories they ever had.
I'm sorry you feel that way and pray that you keep an open mind and heart.
NDE can be identified thus because the thought processes are crytal clear and suffering is all gone. How can one think then even better and without any "drag" than even when not sick... at a very time of being sick and losing consciousness... It's like everything stops, the body factory rumble, and you go about and it is so peaceful and quiet. Then you start hearing voices of philosophy that immitate the voices of loved ones and what not. As I wanted to wake back up, I could not and it felt like a plastic bag was being wrapped around my head, and I kicked and screamed trying to stop going down this desert path of desolation. Then a giant hand picked me up by the hair to the side of the trail and smacked me with the last shrub of green grass around to consciousness and back to pain, fever, suffering, confusion and delirium. I later found that this giant hand is the same as the vision of Jeremiah who was picked by the hair by a similar giant hand. Mine dragged my body away from the desolate path of starvation, pulling me by the hair.
My father had one and, while he didn't have a personal encounter with Jesus or get drawn into a tunnel of light, he said he floated over his body and could later tell the doctor what he did and who came in and out of the room during the brief time that he was dead.
