I don't know if it was a NDE but I had an alergic reaction and passed out, I found myself floating near the ceiling, able to see and hear everyone in the room, including myself, while people around me were trying to revive me.
(I noticed that everyone else was better dressed and that I needed new shoes)
Astronauts reported the same sorts of experiences when they went through high gravity training. When the brain shuts down due to lack of oxygen, you have some pretty interesting hallucinations.
Ever get those shoes?
This is one of my favorite passages in the Bible.
1 Cor 15: The Resurrection Body
35But someone may ask, “How will the dead be raised? What kind of bodies will they have?”
36What a foolish question! When you put a seed into the ground, it doesn’t grow into a plant unless it dies first.
37And what you put in the ground is not the plant that will grow, but only a dry little seed of wheat or whatever it is you are planting.
38Then God gives it a new body—just the kind he wants it to have. A different kind of plant grows from each kind of seed.
39And just as there are different kinds of seeds and plants, so also there are different kinds of flesh—whether of humans, animals, birds, or fish.
40There are bodies in the heavens, and there are bodies on earth. The glory of the heavenly bodies is different from the beauty of the earthly bodies.
41The sun has one kind of glory, while the moon and stars each have another kind. And even the stars differ from each other in their beauty and brightness.
42It is the same way for the resurrection of the dead. Our earthly bodies, which die and decay, will be different when they are resurrected, for they will never die.
43Our bodies now disappoint us, but when they are raised, they will be full of glory. They are weak now, but when they are raised, they will be full of power.
44They are natural human bodies now, but when they are raised, they will be spiritual bodies. For just as there are natural bodies, so also there are spiritual bodies.
45The Scriptures tell us, “The first man, Adam, became a living person.” But the last Adam—that is, Christ—is a life-giving Spirit.
46What came first was the natural body, then the spiritual body comes later.
47Adam, the first man, was made from the dust of the earth, while Christ, the second man, came from heaven.
48Every human being has an earthly body just like Adam’s, but our heavenly bodies will be just like Christ’s.
49Just as we are now like Adam, the man of the earth, so we will someday be like Christ, the man from heaven.
50What I am saying, dear brothers and sisters, is that flesh and blood cannot inherit the Kingdom of God. These perishable bodies of ours are not able to live forever.
51But let me tell you a wonderful secret God has revealed to us. Not all of us will die, but we will all be transformed.
52It will happen in a moment, in the blinking of an eye, when the last trumpet is blown. For when the trumpet sounds, the Christians who have died will be raised with transformed bodies. And then we who are living will be transformed so that we will never die.
53For our perishable earthly bodies must be transformed into heavenly bodies that will never die.
54When this happens—when our perishable earthly bodies have been transformed into heavenly bodies that will never die—then at last the Scriptures will come true:
“Death is swallowed up in victory.
55 O death, where is your victory?
O death, where is your sting?”
56For sin is the sting that results in death, and the law gives sin its power.
57How we thank God, who gives us victory over sin and death through Jesus Christ our Lord!
