JT,
Next time you run into one of the ghosts, say this: "In the name of Jesus, whom do you serve?" Demons have the ability to take on any form that they want to. The Bible refers to them as "familiar spirits". Ihave friends that were approcahed by a familiar spirit that took on the form of an Indian princess. The spirit showed its true colors when it asked them to leave and the people refusedto move out.
They don't like being challenged and they certainly don't like being evicted - it took a group of us to get rid of three that were in a house that I used to rent. They were somewhat noisy and you could feel a sense of aggression as soon as you walked in the house. If you stood in the spots that they liked to dwell, you would feel a cold chill start at your feet and then work it's way up your legs and back. These three unwanted guests were attracted to the hosue, because a Mormon couple lived there before me and the husband used to beat the crap out of his wife. He even threw her down the steps - the railing is still wobbly to this day.
In your case, these spirits may have been there for a long time, which means that they are very rooted. I believe the Bible when it says all spirits (people) return to the Father. So, anything that we run into is usually up to no good. Rick says that one of the latest photographs showed a dark mist/cloud. I don't like it and I think it needs to go. I don't mess with these things, because I know how they affect people and what they can do to relationships. Man, the experiences that I can tell.
Anyway, food for thought...
