I think there have been a few people that have had their predictions come true. I will give you what my opinion is, psychics do exist and they are good at reading the past and present, but very few of us have had the big picture predictions that we have been told about come to pass. Once in a while a psychic may correctly predict a phone call or some other small event.
What I've learned from my own experience and from reading everyone else's postings is that no psychic is right for everyone, we may recommend a psychic that we establised a good connection with but that does not mean that the next person will have the same experience. No psychic is 100% correct because everyone has free will. I have learned to call psychics and ask them about my current situation and offer guidance. Most psychics will give you future predictions and if they come to pass great, but I woulld not hold off on living your life based on a future prediction, because like I said before none of them have been 100% correct everyone.
