[StormyWroten]

Ok, I had a dream where the world was ending, and I was in my neighborhood and Miley Cyrus and Billy Ray Cyrus were there and they betrayed me and my friends and almost got us killed then me and my friends were going house to house gathering people up and then we got ready to go to my crush's house, but when i got there it wasn't my crush in the house it was my mom and my two six month old cousins and my two year old brother along with my other two year old cousin and they were all lying in the floor dead with blood all over them, and at first i thought someone killed them other than my mom but then i looked up and saw my mom standing ar the sink washing dishes, and i said "Mom what happened?" and then i noticed the bloody kitchen knife besid ethe sink and i was scared, i had this weird feeling in my stomach and i was going to leave but then she said "I've been waiting for this to happen." then i yelled "NO!!" and she ran toward me with the knife in her hand stabbing at me but she kept missing nd i was fighting her away, then i grabbed the knife out of her hand and i dont remember where i stabbed her but i killed her and she dropped to the floor and i was crying but when i went outside my friends werent there and thats all i'm saying about that dreamm.. Well does anyone have any idea what this means??
