Are indigo children real?

My mom met a psychic and he told her that I was an indigo child before she mentioned she had kids or anything. Then a year later I was in a play with a man who is also psychic. He randomly told me one day that he thought I'm an indigo. And I never told hum what the psychic my mom met said either. But I was looking indigo children up, and it seems like they have ADD or ADHD or autism. I don't have any of those things, but I match every other single characteristic. So, I was wondering, are indigo children real or not?
