The best way to train your latent psychic abilities is ti find a legit teacher or a legit psychic who trained with someone or some school – yes, there are small localized schools for this sort of thing.
In lieu of that, there are books on training yourself. Even playing with a deck of ESP cards – or just using 6 cards from a regular – put all 6 together, pick out one face down, and try to guess which one it is. You will be exercising the part of yourself that is psychic.SImilarly, but much harder, with peole you know, try to imagine their back story if you don’t know it, then get to know more about them and see how much is right.
Be wary of charlatans on this path, as well as people who follow the dark energy. Wicca is a positive place to start, though some Wiccans can be bizarre or negative, many are interested in what you want.
Their are also ESP fairs in any major Western metro area at least yearly if not more often.
