I have noticed that sometimes my dreams are quite simple visual metaphors:
I dreamt I walked through the doors of my local nightclub but nobody was around. Walking through some dark corridors and passing through push doors I found myself in the bright, noisy arena of a cattle auction which had a sunken floor. Men surrounded the edge, peering down, looking at the animals, only that the cattle being led around the perimeter were horse-sized dogs. "Who'll give me 450... 450...475.... Done!" could be heard over the Tannoy I followed the animals out through a shiny steel-lined corridor and ended up in a room with carcasses hanging from the ceiling. End.
My interpretation was that nightclubs are cattle markets. In my locality a 'dog', at the time, was a derogatory term for a woman.
