My son definately fits the definition.
In the last week his intuitiveness has increased. He gets weird sensations when we discuss certain things going on or predicted. We talk about dreams that I have had and some of them cause him to get weird feelings.
examples:
When we talked about the Oct 14 th event he felt nothing.
I showed him the Mayan calendar and something clicked in him and he said "what is that?". He felt the urge to go and research more about it.
I would like to know whether any other of you that feel you are an Indigo are feeling similar increased sensations.
