Weird week

 Last Thursday Cossacks performed in my school. When I entered the auditorium all my classmates had already been there. The head teacher told me to come in really quick. The cossacks' troupe started their performance. Everything was gaily and great. They sang their favorite song 'Luba' and a bunch of others such as:  "jekhali kazki", "kak mi sjaden  vkrugovuyu" and so forth.
 At some moment,  the head teacher and everyone in the hall broke into a dance.
 I was haunted by the feeling that everything that was happening  that day I already saw, for I could predict every next step of the teachers and those unknown to me people on the scene. After the concert we had taken a couple of pictures.
 From that day on I went on being haunted by the feeling that everything would happen I know.
 On the next day we had Russian, Maths, Reading and PE. Although I was in the lessons for the first time I could predict every next word of the teachers.
 In the morning I told to the guy sitting beside me that we would have a test on Reading and called up the pages on which there were the questions to it.  In the end of the lesson the teacher just confirmed them.
 I literally could predict everything in my mind: What food would be given at canteen before it was announced; What computer games and cartoons would be discussed in the class; Who would get scolded today and what for, before they did anything to provoke the reproach; The day we'll go camping; The moment when a dog in the street would burst into barking.
 It had been happening for a few days so and I felt a bit weird for even though I knew  what would happen in the next moment I couldn't do anything about it.
