One of the "symptoms" that my friend had was that he would have these "prophetic" events were he would have an intuition of something happening just before it happened but at times, it was rather confusing as to which actually happened first. At other times, it was quite convincing. Even so, he has since given up on these kinds of "signs and wonders" because, of course, that has issues of its own for theological reasons. There were many reasons to believe in such occurrences. One specific example was when he was putting a nickel on end on a counter that had a relatively rough surface. As other people began observing, he just grabbed the nickel and abruptly placed it down on the rough surface and let go while the nickel stayed on end. Sure, it could have been a coincidence but incidents such as that were quite frequent. Other people then tried to make the nickel stand on end but they were not able to do it. It was like his belief was so strong that he just made it happen. It was things similar to this that irritated his immediate boss so much that he refused to work with him any longer and actually fired him at one point even though his job performance was excellent. The owner invited him back but he just quit. It was shortly after that, he had a massive attack of sz where he was not able to sleep or eat for three days straight. It is a good story considering that he was able to make a complete recovery all on his own.
