Black Robe/hooded Figure

I know this isn't a dream site but my recent experiences I can only describe as psychic. Preceding my experience for about a week or two I've had a series of dreams of hooded figures and prior to those, firstly, I want to recall something: weeks ago a person I went to school with had randomly crossed my mind. Since then I couldn't get her off my mind, and she wasn't even an acquaintance or someone I knew closely or personally. She was just someone I would see around, a popular girl at school. I never kept in touch with her, not even on social media. Well recently on the news she'd popped up as someone missing. The public and news believes foul play is involved. I'm afraid to tell anyone about my precognition because of the sensitivity of the issue. I have visions of her surrounded by water and flecks of black dirt or pieces of floating bark. When I think of her, I feel strangulation like hands around my neck. I try to block it and avoid it. Since then for a few nights I have had dreams of black hooded figures. Then last night I woke up, fully awake - and saw a black hooded figure in the darkest corner of the room, it looked like it was holding a dim candle - like in a ritual, almost like an acolyte in mass. Like it decided to manifest itself physically. I said to it in my mind, "Yeah - that's all you CAN do." Then it disappeared. She's still missing. This is happening on the other side of the US, and this random connection has frightened me. Is it just coincidence? I don't sleep much as I have an infant who keeps me awake sometimes. I know what I saw.
