A dream I had [draft 2]

Everyone has had been dreaming. Some dreams are wonderful while others are terrible. I had a marvelous dream last night. In the dream I went to school as usual, and on my way to school, a witch appeared in front of me out of the blue. She told me that she would attack my school and kill everybody, then she flew away. It made me afraid, so I ran to school in a hurry. When I got to the street behind my school, I was surprised at the condition─ My school was gone! Suddenly, the witch appeared, laughing loudly, and she said she had cast a spell on everyone to ruin them, with that she indicated that I would be the next one. I tried to escape in vain, so I decided to fight her and I threw a stone at her. To my surprise, she turned into a smoke after being hit by me, then the smoke disappeared. A math book lay on the place where the witch had been. Finally I woke up, this dream may mean that I ‘m really afraid of math and want to avoid it, but after doing this dream, I decided to try to overcome this challenge from now on.
