I get too creeped out to watch programs like these regularly. For some reason these are the most tolerable for me.
Most Haunted
http://www.travelchannel.com/TV_Shows/Most_Haunted can be a little funny sometimes as I think the crew is so nervous that they are jumping at their own shadow and other times I tune into where they are and can feel there really is something to the situation.
Rescue Mediums
http://www.wetv.com/shows/supernatural/rescue_mediums/ is one of the better programs I have watched other than for the fact that someone thought it a brillant idea to interject all sorts of herky-jerky deliberately creepy reenactment flashes. I do like that they try to help any stuck spirits cross over instead of just leaving them miserably reenacting traumatic events.
One show that scared the dickens out of me watching it in broadday light with my Mother was 'A Haunting' on Discovery (

http://en.wikipedia.org/wiki/A_Haunting_in_Connecticut#Specials ). This is a reenactment show and the episode I saw a young couple moved into big beautiful house being sold for a song and the current owners camp out in the living room with all the rooms upstairs nailed shut. The realtor wouldn't even go in the house. All kinds of stuff started happened and years later they finally get in a psychic team who says there is some sort of demonic portal in their kitchen and call in an exorcist that clears the place. I didn't care for that program as I felt it was much more than the others it was trying to scare people half to death unlike the other two.
I once caught a bit of a ghost show on bravo I think with a group of collage kids investigating hauntings. It rubbed me the wrong way with the young guy heading up the group being rather self-important and pretentious IMO. They would be up in the middle of the night trying to bring out the bad entity they thought might have driven a young man to suicide trying to get their gizmos to pick up something :crazy: Yeah lets provoke a possibly murderous entity and see what happens!!! :banghead:
