Be well rested, prayer/meditation/protective ritual the night before, and wear/carry protective items.

I don't prepare spiritually at all, I just go. :-|

I wear or carry protective items only.

I have prayer/meditation/ritual on site where I plan to hunt ghost.

I have a group of people who pray/meditate/perform rituals for my protection while I am hunting ghost at a location.

I only take protective measures IF and WHEN I run into a negative thingy while hunting ghost.
