I did not "see" anything other than a bright light, but I was overcome with an incredible feeling that I was in the presence of, and communicating with somebody who was conveying a message of absolute love for, and total understanding of everything that I was. The feeling of euphoria is impossible to fully describe, because of the absoluteness of it.
I wanted to stay where I was. It was the best feeling I'd ever experienced, and I was content. Somehow, I was "shown" some bits of what I had to live for -- people I had not yet met, and amazing places and things that I had not yet seen or done. I don't really remember making a choice to return, but I woke up in a hospital with a broken back and other injuries. I later learned that I had been hit by a car while riding my bicycle, and was given CPR by a passing stranger.
It makes me uncomfortable to talk about this because it's all just so unbelievable, but there it is.
As the years have gone by, I've met the friends and family that I had in my visions, and I've also been to the places and done the things that I saw myself doing in the vision.
My whole perspective on life was changed by this event, and I have no fear of death whatsoever.
