We had them in my childhood home. I saw an elderly man, he sat on our screen porch, we had one of those glider type things. I was a child and did not know there was anything out of the ordinary seeing this man late at night on our porch. My mom and I both saw a young girl there. She would walk by me around a table and disappear. My whole body would go cold and I would jump under the covers, and it still would take awhile to get warm.
