Based on a real story.
Once upon a time, there was a man who lived in a village. The village was located on the bank of river saryu. There was something strange about this man. He was always found wet in the morning, and that was his daily routine. Even he was clueless of this unusual happening. The villagers & his relatives got worried & decided to follow him one night.
One night when he fell asleep, few people waited & glanced to know the mystery. Suddenly, he stood up still in deep sleep & started walking towards the river bank. Villagers stood their perplexed & gradually followed him without making any noise. And what they saw was beyond their imagination. The man jumped into the river, had bath, came out & again went to his place. He was still in sleep unaware of all this. Villagers were shocked on seeing this very situation. Now, here comes the interesting part, in real life he had no idea of swimming and he didn’t know how to swim.
Later, people decided to wait for the next night. They planned to go near the river & stop him from jumping into the river. The next night arrived. They followed him in the same manner. As soon as he was going to jump in the river, they shouted from the back. He woke up that very moment but had already made that jump. And as he did not know how to swim in actual, he drowned. His mind was trained to swim only while sleeping & actually he was unaware of swimming.
