I have been using a tarot deck of cards for a few years,but I only use them for fun on family and friends.However over time many the things I predicted have come true.Do you think I could just be using my woman's intuition or it was coincidence. I don't even know if I believe in psychics.How can you tell if you are psychics?

I once did some of my friends fortunes with tarot cards while at a camp, and almost 99% of the predictions either would happen, or had happened at the camp that week.
They tend to be true, just because they are sort of vague. Your mind also focus's on the true details and kind of glosses over the non true bits, so you sort of see truth in all the predictions.
I don't know if they are actually real or anything, I just reckon, hey, tarot cards, how can they be magical or stuff like that, if they rolled of a production line, and you bought them for $10.95?
