More weird dreams
Furry snakes (fake fur too, yuck) with cats' heads were menacing trains going through Purley, jumping on board and killing the passengers. At some point the dream switched to looking like it was shot on 16mm black and white film, and when I looked out of the window of the train I yelled "continuity error!" cos the view outside was looking down the side of the train instead of out at the fields.
The ticket inspector reassured me that it had been done for dramatic reasons and I shouldn't worry.
