My sister is seeing dead people.?

I will start with the earliest experience I can remember ... I was sixteen years young and spending the night at my aunt's home in South Carolina .. My aunt and I were watching movies and eating junk food and I made a pallet on the floor to sleep on and retired for the evening . It was a little after midnight and my aunt woke me up ,she was upset and asked me to look out the window and tell her what I saw..I did as she asked and looked out the window . First, let me explain how the place was set up .My aunt lived in a mobile home park that was off a paved road across from a church. The entrance to the park was a dirt driveway with a field on the left as you enter, after the field, were mobile homes lined up on the left and the right side of the dirt driveway. Her home was on the right side of the park and was the second home on the right... I could clearly see the field from her windows .. In the field I could see a lot of hooded being out in the field some were tall and others were short the color of the hooded robes that they were wearing looked to be black but not sure about the color since it was night time but it was a bright lit night..I'm not sure what they were doing but they were bending down and doing something on the ground and getting back up and moving about all over the field.. I told my aunt what i saw and she explained that she was seeing the same thing as I was .. My aunt was sitting up waiting for her husband to come home from work from the second shift that he worked that evening ..My aunt and i went to different rooms in the house and trying to see if we could get a better view to see what they were doing ..Then all the sudden we heard a truck coming up the road as we looked out the window again we saw her husband coming up the Rd by the church and one of the beings was standing in the middle of the road and it looked like her husband run this thing over and we screamed at the same time .. When he got home we were crying and very upset , we tried to explain to him what we had seen and he told us that there was nothing in the road and he drove us back to the spot and showed us . We looked all around with him and saw no evidence of anything.. There was one more part of the story that I left out. There were many dogs in the area and they were barking and growing , but the next morning we asked some of the people in the park if they had seen or heard anything that night but the only thing a couple of them heard were the dogs barking.. I have never forgot that night and neither has my aunt and till this day if I bring it up she wont talk about it.. Still not sure what happened that night .. I think that your sister should seek out those that have had experience in this area and try to find out ways to deal with it .. I don't think that you should encourage her to speak to the entity but be suppotive and be there for her no matter what is going on..
