This is a story that happend a long time ago to my aunt.

She was in her backyard hanging her clothes on her clothesline cause that's what they used, back in the day. Anyways, she was hanging her clothes up and with the corner of her eyes, she saw a dark shadow. She dropped her clothes and ran inside and her brother (my uncle) went in the backyard and was yelling "Whose back here?" You better leave right now?" And my aunt was screaming "He's right there!" "He's right there!" "He's right next to you!" He looked and nobody was there and she told him that "he was right next to you."  And he told her that he didn't see anything and that nobody is out there, so she went back out to hang up the clothes and, she saw it again right next to her and she went inside and saw the dark shadow through the window, so she didn't want to go back out there.
