As gaining extrasensorial knowledge, that is to say clairvoyance, outside an ecstasy or some other mystical state, is among the signs listed in the Rituale Romanum for demonic possession, it's not something that the faithful should be pondering. Personally, I've always found that a preoccupation with occult knowledge (by this I mean hidden, not the more sinister connotation) is the mark of a mind that wishes to exert power.
Knowledge of the future or hidden things profits a man nothing; persistence in the Catholic faith and deliberate abandonment to Divine Providence is the only sure control over one's live, in this world and the world to come.
