Well, this happened to me as a child so it could have been just my imagination but I was peering out my window one night and I saw something near my best friends (who lived next door) window. It was white and appeared almost like a fog with the shape of a woman. It disappeared into my friends window. I didn't think much about it until the next day when my friend said that she had seen her dead aunt in her room the night before. Thats when I told her what I had seen. So, not sure what it was and call it what you will but it did seem a strange coincidence.
