I remember those episodes, that prison one was freaky. They had one a few weeks ago where the lady's bedroom closet door kept opening and closing and no one was in the room. At one point though two people were in there talking and they heard the closet door open but didn't see anyone there. They tried to debunk it by recreating how someone could be doing it but they couldn't do it. They claimed that house to be haunted.
There was also the one down in New Orleans at a plantation where they were filming with a thermal camera. The two head investigators were walking around outside at night with the camera and some figure ran right in front of them. They couldn't see it with there eyes, but the thermal camera picked it up. When they froze the shot they could see the outline of a head and shoulder. Freaky!!!
Like I said my husband and I love watching that show, so I'm sure we have seen every episode. I'm so interested in this kind of stuff.
