I dreampt I was at work, falling asleep in my chair. One wall of my office is window floor to ceiling. So if it's light outside my office is well lit but at night I turn on the lights. Anyway, suddenly everything goes dark, the building tilts 10 degrees and there is a deep rumbling. Well the computer is still on and connected to a video I'm now watching, so I'm wondering what happened. I consider if I should hide under my desk or move to a higher floor.

A few things: there is ocean water literally a meter below the foundation. I can walk out and stand in front of the water lapping at the shore. Every time there's a storm surge the lower buildings get flooded and they're even closer, say .5 m. So I start thinking it could be a tsunami.

So the other thing major is earthquake. It could be from a fuel fire since there's an industrial fuel storage nearby.

Lastly, nuclear blast.

So I go under the desk to take a nap, I'm so tired in dream then I hear people screaming and I don't even care, takin a nap.
