I had a dream last night that i was on a beach just chilling watching the water when large waves started to appear on the horizon. waves started crashing up against everything and i had to move inland before waking up. 

woke up to pic related on the news.

It's an interesting coincidence, but I don't think it's anything more than that. I agree with the anon above me. Personally, I dream about giant waves multiple times a year. If there was at least 1000 users lurking on this board who have this dream once a year on average, that would give us a 94% chance that at least one person will have such a dream on any given day.
I think there's far more people like that on this board which means that in all likelihood, multiple people have had this dream last night. This post seems to confirm that (). It just seem very unlikely until you examine the numbers.
