I saw something moving by my window. I was terrified and ran downstairs. I found my mom in the kitchen, getting my brother ready for school.“Mum, did you hear anything? I, uh. I thought I saw an alien.”“Are you all right? Just a dream ! ”Mum answered. Then I went back to my room. As I walked to the window, I cried, I saw a little alien, no more than three feet tall, with big and black eyes. It tried to run between my legs and escape through the window. Although I was scared, for some reason, I squeezed(挤) my legs together in time to catch it. It took out something and hurt me. I felt a terrible sense of nothingness and fainted (晕倒). Then I woke up. At first, I could hardly move. I wasnt sure whether it was a dream or not. I pulled myself out of the bed and walked downstairs. I saw my mum in the kitchen. She was really getting my brother ready for school, wearing her pink clothes. Then I realized it was just a dream because in my dream she was wearing her work clothes.From then on, I always dreamt about aliens and all the dreams felt so real. At that time, I really thought maybe I had some kind of relationship with aliens. About two months later, I stopped having such dreams.
