Dream of demons, falling, hands

I'm in school and walked into my english classroom were my teacher turns into a giant spider, my classmates turn into demons and my teacher chases me until i loose him. i walk down another corridor and find my sister drinking the blood of my best friend. she dropps him to the floor and starts slowly walking towards me making me back up until i hit the wall. i slid down it crying. my sister stops walking towards me and stares at me before vanishing in a puff of twisting black smoke. a teenage boy i have NEVER seen before pulls me to my feet. He tells me its just a dream, that he is a friend. then the world changes in puffs of black smoke and he's the last to go. i'm then in a white room and there's this green swirling portal in front of me. i walk towards it and into it and find my self standing on a cliff edge in a wasteland. the sky is dusty green and its like the stars are falling from the sky. as i look down into the wasteland i see a battle raging before me. a raven flys and sits on my shoulder, cawing loudly. the boy comes to me again and cups my face in one of his hands. he puts his head to mine and the world starts spinning and i wake up.
