I had a dream once that was followed by reality the very next day. It was very disconcerting. However, in my case, it was very insignificant. It involved looking out my window at a church on a hill, and ironing blue curtains. There is a reason why that happens. I read about it once, but can no longer remember it.

Most of our dreams are our subconscious trying to cope with problems that are bothering us. Dreams use amazing symbols, because they are manufactured by our right brain which only has the language of symbols. Bleed over, where the left brain provides language, is very rare.
