I did not watch the links provided. Just wanted to vent that I know a medic that turned into something in between a medium and shaman, abandoning "traditional" practice. She developed her own healing technique, a mix between shamanic rituals, reiki, flowers and singing, plus she can see your aura. She can contact guides, perceive ghosts, and have had the pleasure of perceiving angels. Or so she says, of course.
Why I am posting here? I want to say, I believe people born with this skills can come from any professional corner. The good part comes when they believe in them, develop them, and make a living from them.
