My mother and her sister, now in their late 50's went to a field together when they were under ten years of age. They lived on farm land, which is a total of 64 acres. My grandparents were searching for them for over ten hours. When they finally found their daughters, they ask who they were talking to and they replied that they were talking to the big rock floating in the field. My mother has a pinhole on her arm, that she has had for as long as she can remember. She believes that it could be from this event, but she cannot be sure. I believe that this should be further investigated.
