I will tell you one thing, I know some some people that did this, and basically their lives where going normal, but after that, their lives started to follow what was predicted (being it bad or good), so technically its a game that decides your future, not reveal it
Its like your life is going normal, but if it end up saying that you will lose someone you love, or that you will suffer an accident, this will actually happen, because you did the fortune telling, and it actually "created" that future
huh? like black magic?
