I believe in these types of situations for sure. However, I don't think I've had any sort of prediction like this come true for me. Not yet at least, the only one really was when my Dad bet me $500 that I wouldn't run faster than his mile 4:51 when I was a Freshmen in High School. My Grandpa told him and I that I would run faster than that. He was right, my last meet of the year I ended up running 4:43!
