"A new type of person is coming
 into incarnation right now, almost a "next step" as humanity 
progresses. These people hold great hope for the future-the promise of a
 new humanity and civilization. They carry different
 energies, paradigms, and ways of thinking and feeling. These new people
 are called "Indigo Souls" because clairvoyants notice that the color 
indigo is unusually prominent in their aura. Indigo is the color of the 
third eye; these souls have a high degree of activity in their third eye
 center. During the years we have come across thousands of Indigo Souls.
 Most of them are already adults, but very few know they are Indigo or 
understand their soul nature. Many are struggling because they are 
different. They have a depth of feeling and thinking that differs from 
those around them. They have powerful internal forces of energy, 
intelligence, and feelings that they often don't understand, and 
consequently find difficult to manage. They are unusually sensitive, 
making them more easily disturbed by things that don't bother others. 
They carry aspirations and visions that make them long for something 
more, and be dissatisfied with the world as it is. They often feel 
limited and  frustrated  by what is considered the "normal world".
If this description speaks to you, then you are probably an  Indigo Soul.
Again, this is my abstract from the "Preface" of the book "Indigo Adults" by Kabir Jaffe & Ritama Davidson
