Dreams don’t stay with us for very long. You wake up remembering every detail of the adventure you just had, only to forget it completely after breakfast.

Maybe you had a vision, would you simply dismiss it, or spend a few seconds writing it down so that when it really happens, you know where to find solid confirmation that you didn't make it all up?

Now, what does it mean if 300 people had the same dream on one single night? It would be a waste if everyone kept the dream to themselves.
