Collapsing Launch Pad

I'll keep this brief as there wasnt too much detail .

In a vivid dream last night i was running away from what looked like a commercial building mixed with a missile/shuttle launch pad. Almost looked like a post modern space port.

In the dream i was running away from the building which appeared to be about 600-1000 feet in height. I was running in a concrete channel similar to the blast channels for launch pads or an aquaduct.

At about a half mile out the building collapsed, hundreds of people were running in the channels.

Felt like sharing this one for no particular reason.
