While waiting for a bus in my local town centre, imagining a gigantic shadowy tyrannosaurus rex running through a corridor made from the connected empty shells of all the nearby buildings, and this thing was spying on me through an open window and where it focused an eye on a nearby individual sitting on the bench where I was sitting and he began to transform into a lethal reptilian humanoid with a long muscular tongue. It would do this to another human and another human. A woman from India walking up the road transformed into a disk shaped thing with many arms and many heads sticking out of the side and she cartwheeled in my direction spinning past me as a very fast speed
Wherever there were buildings made up from shops, flats, terraced houses and any houses that seemed to be very close together, this lethal creature would make it's path. Sometimes through a window one would see the tip of its tale or or one of it's large teeth.
Eventually in my minds eye the vast creature escaped from the area by entering a large black vortex and disappearing. And during this time a man was chatting loudly to himself probably having the most important conversation in the world.
