That has happened to me before as well. It wasn't always necessarily something bad but when the bad things did come true it was suprising yet saddening at the same time. I believe that everyone has the ability to see the future in their dreams and they sometimes will and then see that same image at some point the next day, week, month, etc. I think that it is a form of Deja Vu and it only happens to some people though. If you want to share your dream then feel free to and I will try to help as best as I can but if it is truly something you would rather keep to yourself then that is fine as well. The last thing I would ever want to do is force you into telling me something that you didn't want to in the first place.
