Hi,
I wrote an article about how I overcame my fear of spirits:
Overcoming a fear of the spirit world » Extra Sensory Perception - Intuitive and Spiritual Development Blog
Basically, the gist of it is that you don't fear ghosts and ghouls once you realize what they are and that they feed off your fear. Send them fear energy and they expand and you get more scared, ignore/banish the nasties and they shrink.
