What do dates mean in dreams?

I've had a dream where I dream something occurs in 2033.

Both times, I've used a small, dice-like crystal. It is rounded on one end, a point on the other (like a cone with the base sticking out). I throw it, and I see the wall nearby turn into a date, "Ma (March? May? I can't remember), (13? 17?), 2033. I see war machines near the dates, but I know something extremely bad was going on. At that time, I will be 46 or 45, depending on the month, but in the dream I think of how I will be 50.

If other dates (in dreams) are seen in the future, are they signs of possible prophecy, or are they unconcious turning points that I already expect, and am concerned with?
