dreams - within one hour - 4, 5, 6 storey pub

I don't know how the human mind does this, "Between the hours of 7 a.m. and 8 a.m.," I had this dream about a small (or rather compact) pub.

It was at least a four or five storey, but maybe a six storey, pub with a wooden staircase winding up the centre of it. Decorated in a stained wooden panelled fashion. Filled to the brim, rammed to the gills, with hundreds of revellers. A bar on each floor, and some old friends... There was even some kind of Viking shield game taking place on the second floor. It was full of narrative and dialogue. And LIFE.

"How does the human mind do this," what ever it does, when we're dreaming?
