Once I heard about a man, who hid the treasure with a lot of gold in country where I live. I decided to find it in any way. I wore my jacket, took my dove with me and went towards the adventure.

  I ran, swam and rode on my bike. That was long trip. And then - I remembered that I forgot to put my hat on! I decided not to come back. I decided to send my dove to bring me my hat. I wrote a letter to my mom so she will give the dove my hat. I carefully threw the dove with letter in his beak and he flew away...

  My mom gave my dove the hat and he flew to me. I continued to go.

  When I came to the place where must be treasure, I saw a man. A man, who also wants the gold. I spoke to him, offering to split up the gold, but he didn't want. Somehow I made him angry and he challenged me for a fight. I accepted. I fought him. And won the battle. He was crying. He asked forgiveness, and I forgave him. Then we finally found the treasure and he gave me all gold he must have taken for himself. And then...

 I woke up. That was a good dream.
