You don't have to be a psychic to predict that someone is going to die, it is the most accurate prediction you can give, we are all going to die at some point.
I could claim the same sort of premonition, I dreampt a couple of years ago that I switched on Sky and the reports that Michael had died from a heart attack was on, and that is what happened on Thursday night, but I don't see it as psychic, just a dream.
I do think there are people out there with extraordinary perception, but I supose every medium in the world will be trying to connect with him. Wait for the stories.
