An essay ending with the expression god it was all a dream

I woke up to the sound of a loud banging on my door. Weary from last night's party, I scrambled to find my glasses. The loud banging almost hurt my ears. I quickly opened the door, not knowing who or what was behind it. As I carefully pulled the door, a woman in black dress and a black veil stood before my eyes. She didn't say a word. I stood there frozen. I wanted to run, but I couldn't. Then, the woman lifted her veil and started screaming "What did you do to me?" Now, I realized, her face was covered with blood. I pushed her away and run as fast as I could. To my surprise, I fell down the stairs and I opened my eyes. I was back in my room, sweating with all my might. Thank God, it was all a dream!
