Well, NDEs and "Past Life Recall" aren't New Age concepts. I know many people get confused about this, but New Age is NOT mysticism. That is to say, New Age uses mysticism but it isn't mysticism itself.
New Age is, basically, a movement that takes all manner of thought - history, religion, science, mysticism, philosophy, etc - and SMASHES it all together into one. It goes beyond Proof and into Possibility. Due to this, it isn't limited by proof and allows a person to build on ideas that haven't been...set in stone, so to speak. The movement also has various "points" it's trying to reach and the "truth" that New Age seeks MUST fit all of these points. Refer to Wikipedia on this, they aren't easy to find.
A unique thing about New Age is that it EXPLAINS. You cannot claim something is New Age if you cannot explain it and connect it to other ideas and theories. This is different from Transhumanism and Transhumanists - the idea of transhumans isn't far fetched, but the ideas have NEVER been properly detailed and explained in Transhumanism, while they HAVE in New Age.
If you see the hype of hard logic and chemical science as Enlightenment, then New Age would be Endarkenment. Think of the Allegory of the Cave. Many people thought Enlightenment was everyone coming out of the cave and "into the light". However, this isn't the case. Instead, everyone was drawn to the "light of the flame". While this DID help them measure and make some sense of the area of the cave they were in, they got so addicted to the fire that they never left it. In order to get out of the cave properly, people have to go deeper into the cave - into the darkness - in order to find the real exit. That's the analogy there - going into the darkness, Endarkenment.
New Age, as a movement, is meant to do many things. I'll list basic ones here:
1) Have the world go through many revolutions - political, cultural, economic, scholarly, etc
2) Bring science back to its philosophical bases so that it can evolve to a higher form.
3) Rediscover lost knowledge and spread all the knowledge we have in the world today all across the world.
4) Create communities for mentally and spiritually gifted individuals, known as ESPers, so that they may flourish instead of being hunted down and alienated.
5) Fuse religion and irreligion. (Exoreligion has been seen to do this, like with Scientology.)
6) Discover the secrets of human evolution and upgrade ourselves without interfering with that evolution (transhuman stuff right there).
7) Become "one" with the universe; per se, healing and living alongside nature, expanding ourselves throughout space, attaining spiritual and mental prowess to that extent, etc

Those are a few points, not all of them.
A good way to get into New Age is to research "Ages". Many Ages are said to exist in the present day and from now on. This includes the Space Age, Age of Aquarius, Information Age, Age of Awakening, etc. Studying modern trends, such as trans and metro life, is also an important thing to do - as those generate a "new norm" which will come into contact with the movement later on.
Personally, I believe the Fourth Science (the main science after Physics), Neuro-interfacing (like with Virtual Reality), and age-alteration technologies will be created faster due to the movement, but that's just the Futurist in me :P
