Sure, ask away. As for these questions:
I came to find i could do this when i started getting weird visions that came in flashes... Those flashes came with physical sensations, and were surprising. Sometimes i could discern what i would see, sometimes it was just a blur. And at all times, i questioned my sanity. I started testing myself and turns out i somehow formed a connection that seemed to be closed before. My best guess is that it is a connection to a "joined consciousness of living" or whatever you wanna call it. I still have a lot to learn and i am not sure exactly what and how i am doing. But i'm pretty sure i'm sane, and it sure does work.
As for the interest: Who didn't wanna spit fire through his mouth and have lighting come out of his fingertips as a child?
In truth, what opened me up to these sensations was Tai Chi in the first place. And the only reason i went to learn it to begin with was harsh analytic skepticism. Fate is not without a sense of irony
