It was cold, dark night. With my younger sister we were swimming by boat to a small island in the middle of a lake. I climbed up a rock, and looked around. Suddenly I saw my sister running from the other end of the lake, jumping over boats and running on the water to me. I asked "How did you ran over the water?" She replied "Water? It's concrete!". Then I saw that the rock I was standing on was placed in the middle of city square. Street lamps were off, dark. Moving through the dark alleys I entered a passageway going under the city. It was heavily crowded. I tried to go to the other side, but when I opened the door to first route I thought "Wait! This is an ambush. The doors will be closed if I enter it!" I decided to go the second route, but suddenly a passer-by told me that someone broken the key, and the place is locked. I moved to the door and tried to open it, to no avail. I hit the door with my fist, and then tried to smash a nearby window, but they resisted my strikes.
