I have a second to share that happened recently to some family members.
My uncle was at his sister's house. Her grandson was going to run to get food and asked my uncle if he wanted to tag along. He said he did but he needed to put shoes on and he would meet him upstairs in a couple of minutes. So the grandson walks down the hall, and my uncle starts putting his shoes on. He looks up and he sees the boy down the hallway just standing there staring at him. He tells him again he will meet him upstairs, and the boy turns and walks into the bathroom at the end of the hall and starts combing his hair. My uncle finishes putting his shoes on, and when he looks to the bathroom the boy is closing the door. He figures he needed to use the bathroom, so he decides to wait until he gets out and keeps watching tv. So he waits and waits and waits. Thirty minutes go by. So, my uncle decides to just go wait for him upstairs. He gets up there and finds out the grandson had left a long time ago. A few minutes later the grandson is back. My uncle is totally confused, and asks him when he left the bathroom. The boy has no idea what he is talking about, and says he never combed his hair or any of that.
On top of it, the boy gets a little freaked out and shares his own story. One night he had stayed in the house and got up in the middle of the night to get a glass of water from the kitchen. His grandmother was sitting at the table, no lights, totally still. He stood there for a minute, and it felt weird to him, so he walked back to his room. On his way back, his grandmother was asleep in her room.
I guess my aunt has no idea these things happened. They don't want her to be scared in her house. But seriously...wtf.
