Do dreams ever come true/predict the future? --- James, Mumbai, India
Dreams can come true. Say you have a dream where you buy a restaurant. Say it is a good, powerful dream, so the next day you decide to call your Realtor and start looking at restaurants. Two months later you buy a restaurant. In that case, the dream "came true". But the dream didn't "predict the future" -- it set in motion a chain of events.
Now let's say that you have a dream where someone you know gets hit by a bus, and a week later that person does in fact get hit by a bus. Statistical analysis shows that that is pure coincidence. There is no scientific evidence that dreams can predict the future. For more info see How Dreams Work and How Lucid Dreaming Works
