First off, let me say that the worst dreams I've ever had involve waves. Large - enormous - ones. And deep, deep water. Mountainous dunes with small clusters of green dune grass poking out like razors, and undertows that could pull a truck into the dark, bubbling sea of oblivion with a single wave.
And people wonder why I don't like the beach.
But I had a strange dream maybe two nights ago regarding some scary beaches. But first, I think that I was in a train traveling along the countryside to some unknown destination. I peered out the window and saw a group of construction workers cleaning up a train wreck that I remember seeing happen earlier in my dream-land. "Looks like they're fixing it up" someone said over my shoulder. Trucks upon trucks upon trucks lined the sandy area leading up to the train wreck, and I assumed that they were helping with the cleaning of the train wreck.
I began to see enormous dunes as we approached a beach. I assumed it was a beach, at least. (thankfully, I didn't see the actual ocean due to the largeness of the dunes). Hundreds of cars were half-buried in the sand, as if one packed day at the beach a sandstorm hit and no one ever bothered to recover their cars. Several frazzled-looking people slowly walked among the dunes. The train slowed down, as if offering to pick them up. Some of them lifted up their heads and slowly waved to the train with odd grins on their faces. Creepy.
