A Terrible Dream

The following is a dream I had during a late afternoon nap recently. After an unusually long period of adjustment post-waking, I decided there had to be some significance to the whole thing. I have yet to figure out just what that significance is however.

It was a clear, balmy day with only a few clouds in the sky. There was a slightly saline breeze. I stood on a small pier, with an unknown companion, amidst a few brightly colored tables and chairs (The kind, with umbrellas, typical of tourist locals). I had the impression that I was in or near LA.
People on the beach, started staring out to sea, aghast. I turned over my shoulder to see what they were looking at. On the horizon, a solid wall of water was rushing towards me. I had the feeling that it stretched the entire horizon, was unearthly massive, and was global in its impact.
I started to run with no regard for my cohort. I ran past screams and gasps of "We're all going to die" and "It's hopeless". I rushed across a street, through light traffic, and darted between towering buildings. The roaring, crashing, and crumpling sounds of rushing water and twisting metal were growing in the background. I pushed my way over construction debris, hopped over a homeless man, and jumped/slid over a port-a-potty. Then, I twisted to my left and up the crude wooden stairs of a building under construction.
The water was swirling and surging up at my feet. I could feel it snap at my ankles, cold and angry. Other people started to rush up from the waters, surging up the stairs behind me. I forced my way up the stairs until I reached a metal barricade. People started to cram in behind me, wedging me tighter and tighter into a tangled mess of bodies and metal bars. Somehow, by my own force of will, I pushed through the barricade, and started up the stairs again. A single man forced himself past me and darted up the stairs.
The top of the stairs ended in a plush apartment not unlike a casino in design. An imposing man sat at a desk at the entry to the room. He was looking at a computer, but turned to glare at the man before me, and greeted him with a gun extended. The man offered a bribe, in the form of a neatly rolled and banded ball of cash. The man waved him inside, then turned to me. I shrugged my shoulders and in exasperation plead "I have nothing", to which he only smiled and welcomed me just the same.
I remained at the doorway to the room, took my cell phone from my pocket, and sent a single text message to my boyfriend reading 'I made it through, are you ok?". There was a brief pause, and then I awoke.
