Mr. Samson was a newspaper editor in Boston, America. On the night of August 28, 1988, when he was on night duty, he dreamed that a volcano (火山) near the Island of Java erupted (爆发) , and that the local people were buried under lava (熔岩).

When he woke up from the bad dream with a start, he thought it was very interesting material, so he wrote it down on a piece of paper, left it on the desk and went home. Early in the morning, the editor-in-chief came to work and saw the paper. He took it for the latest news that something important had happened last night and published it immediately. Only later did he find out it was just about what Mr. Samson had seen in his dream. But it was all too late because the newspaper had already been delivered (传送).And it caused a great panic.

In no time the editors met to discuss the serious problem. They finally decided to make an apology in the newspaper. Just at that time word came that a volcano on a small Island between Java and Sumatra did erupt. The eruption made the small island lose two thirds of its area, and the seismic sea waves caused tragedy (悲剧) in human.
