Before becoming a Catholic, I was Lutheran. I fell away from active Lutheranism in my teens, however (which in a way precipitated my interest in Catholicism) and started studying "psychic powers." Then I got into Ceremonial Magick (the "Eastern Orthodoxy" of witchcraft practicioners, in other words a highly liturgical and well-planned out process.) I tried astral projection (out of body experiences) and tarot cards were something I got pretty good with. In the end I started seeing things, hearing things, etc. My mother called me one day and said, "were you astral projecting, because I saw you in my room last night."
These experiences got progressively more negative and finally I stopped, thank God, and became Catholic back in 1998. That stopped it all. Now of course Orthodoxy is in my sights but that isn't the point of this discussion.
