My grandfather had a heart attack and was clinically dead but successfully revived. Later, when we asked him if he felt or saw anything during that time, he said that there was “absolutely nothing, just blackness”, and then he was back.
My boyfriend has had several surgeries, and he told me of an experience that is more OBE than NDE, but it’s interesting. He was telling me what a horrible experience a total anesthesia was for him, and he said he remembered suddenly hearing a high-pitched sound, and the muffled voice of a woman telling him he needs to “come back”. Then his perspective changed and he could see his body on the operating table, and remembers in detail who was there and what they did. He says he described it all later to his doctor and his mother, but they dismissed it.
I also met a woman who claimed she was a psychic, and she said she got her abilities after a NDE. She was in a car crash, and suddenly she was looking at a dreamlike meadow filled with flowers, a city of white marble in the distance. She said that someone – an angel she says – approached her and told her it was not her time yet, and that she needed to go back. Maybe this one is the closest to a LD. She was a very sweet old lady and she seemed honest enough.

As for her “predictions”, she told me that I’d eventually give up tasseography (back then, people were dragging me to their friends’ houses, and then their friends’ friends, which is how I met her) but find other ways to help people. I rarely use any sort of divination these days, but we’ll see if she turns out to be right about the other part.
On a side note, I haven’t had a NDE, but in my own dreams, both lucid and regular, I’ve sometimes had “boundaries”, a portal or a line for which I was told (or sometimes just heard a voice in my head) that crossing them would lead to a final death.
