Don't believe in 'em much, but I've seen people, including Grandma, exhibit some apparent spontaneous precognition that I can't explain. So anything's possible.
I saw a demonstration once on campus. The guy solicited no money, sold us no books. He was there to demonstrate, and he wowed us. He had mailed the seminar organizer an envelope the week before the presentation with three things - the name of a card, a five-digit number, and a headline. At the end of his presentation, he called on a guy in the audience whom I knew, asked him to name a card. The guy told me later that he had ace of spades in his mind, but he changed and said the king of spades. He gave a paper to one student, asked to write down a four-digit number, did that with three other students, some of whom I knew, and gave it to a fifth student and asked her to add them up. He then asked for a copy of that day's local newspaper.
The seminar organizer opened up the envelope that she'd gotten some days before. In it was one slip of paper saying "king of spades," another with the five-digit number that the student had come up with in the addition, and another with the phrasing of a headline that wasn't 100% accurate but had the general issue right. Now, I'm sure it was a trick of some type, including the possibility that he somehow switched envelopes, but it was a good trick. I couldn't tell you today how he managed it.
