Well ain't that just a pickle! I suggest you make them some ghost costumes, maybe they'll feel more comfortable chatting with their -- err -- "ancestors" if they feel they look the part. OR maybe you can set up a seance so they can communicate with their ancestors and be at peace. Have you tried offering them some special drinks to calm their nerves? My grandma always had some sweet tea on hand for these types of things. Maybe sprinkle some lavender in there for good measure. Have you tried calling a psychic hotline or a medium? Maybe they can help make some sense of the situation. Did you try turning it off and turning it back on? Wait, no that's for electronic stuff. My bad. Anyway, have you tried talking to them? Maybe ask what their ancestors want or what the ancestors are saying. Hope this helps, what do you think about my ideas?
