A story---
"My name is Brita, and I am 15. The story I'm going to tell happened last year and it involved my sister. My mom believes in ghosts and demons and she also practices witch craft. She had a book on raising demons and stuff. My sister would have been seven years old. The book was dangerous and my mom always told us not to even pick it up to open it. I would sometimes sneak away and just look through it and try to say the words, but never anything else.
My mom always tells me that I have a lot of power, and over the years I noticed that I can see ghosts and connect to them. I have my own that hangs around just to watch over me. That's another story though. My sister Anna took the book and was drawing symbols out of it. Just one symbol though, she drew it on the walls, door, on her skin even. My mom found her with the book and freaked. She took it away and I haven't seen it since then. That night though, Anna was sleeping on the couch while my dad and I were downstairs also. My dad was sitting watching TV and I was standing in the kitchen.
There was a black mass sitting beside Anna, to me it looked like a man wearing a trench coat and a hat. You couldn't see his face, he was all black too. He was sitting there, rubbing Anna's arm. My dad just sat there shocked but I stepped forward. The thing stood up and walked towards me. I just stood there and looked at it. It got right up to me, and gently touched my shoulder then dissolved.
Anna never even moved and she usually walks up at the slightest things, my dad just looked at me confused. We talked about it and told my mom too. She ran around the house and did all these "spells" and stuff. My dad put Anna to bed in their room and I just sat in my room for most of the night. I could feel the thing was there with me, but I wasn't scare nor did I feel in danger.
A couple nights after that my friend slept there, we were just talking and then she looked above me. Her colour drained and she started shaking and crying. I looked up and could only see a black shadow, but that was nothing new to me. I asked her what she saw, and she said it looked like me only dead, and my skin had gone a pale green colour. I brought her out of my room and she was fine after that, and I went back into my room to see if the shadow was still there. The man was sitting on my bed again he just got up and walked towards me, disappearing at the last second. I still see him sometimes, walking beside me or sitting in my room but he hasn't done anything to me or my sister."
Yeah, I have seen similar as yours, black hat and black long coat with can not see his face. I used to chase him around the house in the middle of night while everyone else sleep. Been doing this for few years. He won't let me touch him and he never had harm me. So he must be one of guardian angel to watch over me.
