Describe a real or made up dream or nightmare

Once I had a dream that my Nana was getting the mail but she was hit by a car and flew like 2 miles down the the street. So I ran to her to make sure she was okay and when I got to her she was completely fine and unharmed. She just got up and said she just wanted to fly and that she had a lovely flight. And then my dream was over and I woke up crying because I thought something had happened to her.
