Ghost Busters!

I admit I don't Understand these Ghost Hunter shows. Shows like 'Dead Files' yes, they're trying to find out if the person(s) fear is justified and what they can do.The others seem, well obnoxious.I've lived in a number of haunted homes, yet none have been as bad as your average roomate;>!
I was surfing by and caught the one on Sfyfi(yuck)where an "investigator" was yelling insults to get the Spirit to respond. Luckly for him, the Dead guy WAS a gentleman;>.
Just because they're Dead doesn't make them Smart....or Dangerous. Occassionally Annoying;>?
Cheers,
Pat
