The first experience I remember was before I was school age; I am guessing I was about three years old. I was in my grandmother's living room, sitting in front of and end table. My grandmother was sitting on the sofa on one side and my mother was sitting in a chair at the other side of the table. I was playing with cards or small toys on the table. It was evening, so the rest of the house was darkened.
I turned to look at the hallway to my left, about twelve feet away, and saw a figure of a man about four feet tall, all black, wearing a low hat with a very wide brim. I did not see a face or any features, but I did see that his coat was covered with hundreds of little strips of black cloth, each maybe an inch wide and about six inches long.
They asked me what I was looking at, and when I turned to look at them and then look back, it was gone. I told them what I saw, and while they assured me that there was no one, I insisted that I saw it. I don't remember crying, but I must have looked frightened, both for them to ask the question of what I was looking at, but also because they made a show of looking through the rooms down the hallway and assuring me that nothing was there.
This happened so far back in my memory that I was inclined to think it may have been a dream. But it has stuck in my memory all my life, and so many people have seen a similar figure with the hat and/or ragged clothing, perhaps it was real?
This kept going on until I was 9 when everyone of them seemed to just vanish in front of me. Then this year I saw them again and when I went on holidays they appeared when I meditated and appeared everywhere. My friend and I seem to have almost a sixth sense. He can glimpse the future like I can But I can glimpse the past. I'm wiccan and an expert at seeing auras but It seems I can sense death. They were like your description apart from the fact that they never had a hat they were always dressed head to toe in a ragged cloak.
I used to be terrified of them but now I'm not. They show me their past while I figure out a way to free them. So if you see one of them again don't be scared either beckon to them to come over to you or go over to them they arent bad they just want to leave. Ask them a question about the happiest moment in their life then say to them to cling on to it. It seems they choose us for some reason. I think we might all have a secret sixth sense. Use that to your advantage and try to free them.
