Once, long ago I had a nightmare, that I was in a strange world, where there were plenty of surfaces, tunnels, ladders but it was impossible to determine top and bottom, absolute disorientation. That was terrible... I suppose I had a fever that night.

So I was walking down the street. Suddenly I sliped on a grass. Shortly, a huge lawnmower, with meter size blades, was drawing near me. When I was almost closed to death, I woke up.
