Some dooms day stuff. I have a fear of MASSIVE objects, but also a fascination of it.
The color pallet was an ivory cream white for the walls in a gold art deco design.
It appeared to be a subway hub that had a large mall attached to it facing the open ocean.
Sitting on probably a 20, maybe 30 feet wall above sea level as the waves increased.
Standing on the wall hands gripping the railing in front with the entrance to the hub that lead down a flight of stairs of about 15 steps with and landing and another 15 stepes to the main doors to the hub behind my back watching what appears to be a Black Spire miles off in the distance.
The clouds were varying shades and colors of greys and dark blues with lightning every few seconds followed by thunder and turning into super cells at this point moving at unrealistic speeds, not too fast though, but just noticeably faster then average.
The sea receded when a blue beam of light from the thick clouds hit the spire at a 90 degree angle.
It pulled millions of tons water up into the clouds towards and above the spire then let it all crash down in a controlled manner.
The waves were Deep Impact looking, I died being crushed in fear and awe. Didn't wake up, but instead repeated the moment starting a second before the blue beam happened and I retreated into the hub this time only last seconds longer, before waking up.
