WTF? Weird dream!!!!!!!!!!!!?

okay, in my dream last night my mom and I went to my friends to get a text book. I rang the doorbell and a bald man answered. I asked if I could see my friend, and the man said no and slammed the door. I rang again, and my friend answered again but very cosciously and then wrote on the house wall with a pen, "call the Shelton's". I was like, what the hell? He closed the door and I seen him and the man go into a room in the house and close the door behind them. I barged through the house and into the room, and my friend had a machette, and the man was on the ground, face down. MY FRIEND CUT OFF HIS HEAD!!! SO, through protection I forced my mom outside where my friends whole family and the sheltons were doing this to some random people. they told me it was a sacrifising... my mom and I got the hell outta there!!! WHATS THIS MEAN???????
