I'm out in a boat, in a tropical place, like a bay in the ocean. I'm fairly close to a rocky promontory, there is also a beach, and there are swimmers paddling around. Somebody else in the boat points out their dog , just walking like normal on the bottom of the ocean, about 20 feet down. He's hunting for eels. They tell me he found and caught one, and then we see he is hunting another one.

Someone remarks that the ocean surface is strange, unusually calm, and there are these little cups in the surface. I start to think... I think this means that there is... and in the corner of my eye comes a huge rogue wave, broken and foaming, and just overtaking us all as I'm trying to warn "BIG WAVE", but it's too late, I and everything else gets swallowed up in it.
