don't see how experienced practitioners only can answer this but whatever.
i have always been religious, in high school i took a world religions class, and for the end of year assignment i choose to research Wicca because i seemed drawn to it. it wound up really speaking to me, and i converted. but if you want to go back further, prophetic dreaming, clairvoyance, and the ability to sense spirits runs in my family for as long as we can remember. [one of those 'my mother was psychic, and her mother was psychic and her mother before her was psychic' sort of things]
