what does my dream mean

i was with my friend and two guys came up to the town we were in and and killed everyone. my freind told the two guys he would help him so one guy told my freind to kill me i told him dont and i would join up with them, i was going to kill them later i thought so then i turned into some sort of monster like a vampire. then we all looked over a big hill and on the otherside the was hell with a thousand demons and fire everywhere and they were coming towards us. then the whole sky turned red and black and a monster the was huge devil came after me and was hit by a ball of fire. i ran and met this girl and she gave me a hug and tried to stab me. but i told her not to and have her dad give us weapons to defeat the demons. i have many other nighmares about hell and war.
