My vampires

So it started in the middle of the night... my parents were fighting,which is almost every night.Then,I heard a loud bang.I ran to the room,and saw my mom laying on the floor dead.I was so and scared.I saw my dad standing there with a pistel that was pointing at my mom.He shouted at me "Get out of the house...Now!He whispered "if you tell anyone about this,you will end up dead."I ran to my room and packed all of my clothes and a few snacks really quickly.I rushed down stairs out the house!About 16 minutes into the walk I saw a black shadow,it seemed as it was as fast as light.I thought that I was just imagining things,but then I heard it again.Then,out of thin air someone popped up behind be and choked me.
