I read somewhere that it is a gift. You should take care of it, cultivate it for accuracy and don't talk about it too much with others as that spoils some of the spontaniety and clarity. Don't interpret what you see as that is called "colouring." Just stay tuned to what you "see" and leave it at that.
I can't say I have experienced it. I have thought that would be great if such and such happened but then it is a fluke.
Wouldn't it be great to predict the X Lotto.
