I love that show. I don't watch it regularly, but enjoy it when I do.
I agree... that is spooky.
My sister had a friendly spirit in her house. Only my sister could see her. The spirit was an older woman with long white hair and wore a flowing white dress. My sister saw her on several occasions and it actually brought her some comfort. She thinks the woman had lived in the house before, and was happy to see a nice family living there.
Fast forward a few years when my sister and her husband decided to sell the house. As soon as they put it on the market, almost anything that could have gone wrong went wrong. New water heater needed. Part of an overhang collapsed, requiring replacement. My sister felt the spirit was angry at her for leaving.
