Try? lol Like Yoda said, "there is no try! Do or do not." Seriously speaking I know of people capable of such things but my own experience with such gifts is that exercising them requires something of the user and costs them a bit of their innocence and perhaps their soul in the end. I have found that the principals behind what people call the paranormal actually end up being very natural even if not as light hearted as Scooby Doo's principal that all such things are hoaxes and frauds. The paranormal isn't a place for children to play because the principals of the weird are a deadly game of poker between forces that play for keeps. Knowing which is which, good vs. evil (if you believe in such concepts) ends up being a matter of perspective and everyone involved is betting that they aren't wrong.
