This happened about 10 years ago. I was seeing a guy in the army and he had come to town to visit me. We hadn't been seeing each other long. He was staying in a lakeside holiday house that his father had left him and his sisters when his father had died.
My boyfriend and I talked about his father that night, and how much of a mean person he had been. Eventually we fell asleep around midnight or so.I remember dreaming about being in the holiday house, and feeling an enormous sense of dread. It was like a TV programme, where I could see myself and also what was happening outside the window behind us. I could see a big person running down the drive towards the house. I couldn't see his face, he was in shadow. But he was moving very fast, and I had the feeling that he was not happy about something. Just as the shadow crashed through the door of the house, I woke up.
Not so spooky you say? Well, at exactly the same time that I woke, so did my boyfriend. He asked me why I was awake. I told him about my dream, and he jerked - my boyfriend had had the exact same dream! Only my boyfriend was sure that the person coming down the driveway was his father.
I don't see this guy anymore - the whole experience was very bizarre, and it frightened me a lot.
