Once upon a time, a merchant came to my village for the purpose of trading. After a long walk in desert, he decided to take a rest under a tree for few hours before entering the country. And all of a sudden, a door opened from nothingness and an old man appeared saying' 'Welcome to our strange world, and you will spend fabulous moments'' the merchant hesitated for an instant then he went through the door hoping to get something new. All people there, in that strange world came around him, looking for what he was offering of goods. They all did not have money, but they bought from him what they wanted, promising him that they would give him money later. He trusted them and he just wrote their name in paper in case if he forgot their names. He sold all of his goods; happily, he left them, completing his journey to the village. After spending three days, he decided to go back to where he sold his goods. However, something amazing happened, he did not find the door which was under the tree. Sadly, he returned to the village and told people there about what happened. They said'' Show us the names'' then, a man said '' I know these names, some of which are our ancestor's names. That made all people shocked and they just kept scramming in fear.
