Angela at Three Buttons recently posted about coincidences, and here is mine. Personally, I think it is more than a coincidence -- it's an interesting story, whatever you believe!
I was having a dream one night when I was about 16 -- I was in an emergency department of a hospital, and there was a young guy there who had been in an accident. His head was cracked like an egg, and he was wearing a baseball cap. I liked the cap, and stole it.
Then (in the dream) I was having a party at my dream apartment, and I heard a very loud, urgent, angry knocking. I knew it was the ghost of the guy whose cap I had stolen, coming back to claim it.
At that point I woke up. I lay in bed wondering whether to get up and check the door, because the knocking had been so loud in my dream I thought it must have been real knocking which woke me. I didn't get up in the end because I figured if it woke me at the far end of the house, it would definitely have woken my parents whose bedroom was right next to the front door. It was 3am, and I rolled over and went back to sleep.
The next morning we were in the car listening to the radio. The news came on and there was a report about a woman in Melbourne who had been bashed and raped overnight when she answered a knock at the door at 3am! Eeeeek! We lived in the outer 'burbs of Melbourne at the time, and the attack happened in the inner 'burbs.
