I think desensitizing yourself to certain things is a good idea. For instance, I started researching "spiritism" (as JW's call it), specifically Pagan religions and beliefs. I watched verboten movies that had to do with ghosts and demons, etc... Now, some people might not be able to handle that, especially if their fear of demons is very real. I had to do it in order to prove to myself that reading and watching certain things was not going to bring on a demon attack. It never did. Of course, the first few times, it scared the crap out of me and I slept with the lights on LOL. But now my home has dragons and pentacles and the like with nary an issue.
Something only has power if you give power to it. For example, I no longer fear "evil spirits"/demons or think they are real. My BF, on the other hand, does. So when he wakes up scared out of his mind, he has given that concept a power over him. Since I'm rational about these things now, I can understand the fear, but I can also talk him down from his freak-outs. So if you're afraid of, say, looking at Tarot cards... Face the fear and get yours read! I did...also had my runes read. It's all in good fun and will probably assist you in your recovery.
