Describe what Dorothy saw

When Dorothy opened the door, this is what she saw. Outside it was very dark. It was pitch black. All of a sudden the sky was bright with lightning. There were tall mountains covered with snow. In the distance there was a castle high in the mountains with a flag on top of it. Below the mountains there was a huge forest with a stream passing in the middle. Dorothy saw a road which leads to the castle having a bridge in the middle with a stream passing underneath it leading to a lake.
