Dream of girlfriend

Walking threw the old farm with my grandma and there is evil lurking but it will not approach us. My grandma leaves and I head to the farm house where my girlfriend and other people are. The evil gets inside and hurts people. My girlfriend gets away and runs home to get our dog. I'm fighting the evil and I'm really beat up. Our dog magicly gets bigger and I climb on her back and she carries me outside to my girlfriend .
