Well, I do believe God gives gift of visions, but what you see in visions not always means psychic. Its not only christians doesn't believe in psychics, even some jews doesn't believe in them too. Psychic is more what you rely on, like psychic does to Saul in the OT. I like the show of Touched By Angels, shown about tarot cards and psychics. Visions can be relate with prophesy, sometimes God forwarned in anything. Just believe in God does not mean being a christian, or going to church, christian is a personal relationship with Christ. But as of psychic, have to know the difference btwn prophesy or psychic. My very close friend see things in many ways, like before my mom's death, he saw something looks like hospital hall and thought might be his grandfather, till when my mom death, there were hallway is very similar in his dreams. Its been happening from time to time, He thought its psychic thing, and I told him no, its not psychic, its more a vision that God can gives. But psychic is not God's way. Sometimes its tricky to know the differences. Yes, some do have gifts of visions can be forwarned, like Isaiah, John, Peter and some others, its not psychic.
