Write a summary of the following passage (Max 5-6 sentences).

The prisoner Went to bed, but could not get any sleep. He lay awake the whole night. The images of his past life come to his mind one after another. He saw before his eyes his wife, as if alive, asking him not to go to the fair. He heard her speak and laugh. He saw his two children. He saw himself- how merry and free from care he had been before he was arrested. Then he come to his mind the pictures of his twenty six years’ prison life, how he was flogged, how he was chained, how the people stood around enjoying his sufferings. He felt so wretched that he thought of killing himself.
