Thanks for the responses, I'll keep looking into it. I don't think it was a demon. Maybe last time. But I saw this as a man and last time I saw a non-human form. The last time I told it to leave me alone when I sensed its presence and it responded "No!" but then it left me alone for a few months. I sense that this time it was a different thing. It felt different. This one wasn't as bad as the other one. The first one seemed to leave me alone after I become very strong in my faith in God. However, I'm not so sure what this thing is....
thanks again guys
