What do you guys think of my opening paaragraph to my story?

I woke from a deep sleep. I looked round the room and then suddnley rememberd what had happend the night before. The more I thought of it the more my heart felt as if it was in my mouth. Then there was a loud bang at the door. I looked out the window carefully pulling the curtain back, then there they were. The gang I saw violentley beating a person the night before. They were after me, why? What did I do? But then I rememberd one of the gang members had looked at me whilst I ran off in disbelief. I felt as I was going to faint. I let go of the curtain and fell against the wall. Why was everything bad happening to me? Why why why? -
