So for the bit of you wondering what are indigo, crystal and rainbow children let me clarify
First let me tell you, google as a complied amount of info there does not mean all of it is good i personally find some of it lofty or insulting due to ignorant mindsets.
There was a wave as early in the 1970's about children being born with brighter auras than before, and these children has indigo auras, in peaked even higher from 1990 to 1995
They called these children the indigo children, they are part of the many group of individuals called the star children. these children were quite human and were mentioned in all prophecies around the world like the hopi people link here- http://www.crystalinks.com/hopi2.html
indigos and all other children are described to be old souls who have incarnated to help people adjust into the dimensional shift which is coming very soon, since that dimension is native to indigos they know it more as "home" and will be the best people to help you brake into your new wonderful environment.
indigo and crystal children even though not pushed into the spot light even has some scientific finding behind them that they has extra dna coding not found before in other people, but apparently this is changing, since everyone else it getting this coding as well. Do you feel as though time is moving quicker than before? well if you just brushed it off its time to pay attention, listen to that inner voice and focus on the important things in life, be prepared for the journey that will soon come.
well since i didn't have much time to go into this topic as i wanted it shall be addressed later on
