What anon said is that his looking into witchcraft may have left an open door to this. To me that doesn't imply a negative judgement at all, it just implies an awakening to more spirirual perception.
I think it's very interesting that anon mentioned saying Jesus name. Personally I have done this also, I had a really frightening experience on a spiritual level once where I called on God and it was incredible! He definately came to my rescue then and there, it took me years to get over my fear and understand what took place. Although I grew up as a Christian and am now, I also had interests in other cultic practices for a time which I know deepened my senses in this. I have also prayed the blood of Jesus over me which is said to be very protective, and I believe it.
Frustrated, I'm curious as to were you stand right now in how you view death, or if you've had anyone close pass away, or any reason to be contacted that you know of?
