Math Teacher

Alright:
In the beginning of the dream I see that im laying face up, in my b-ball ct. I get up and see my dog barking at me then, then bark toward the entrance of my house. He runs past a few trees and I lose track of him. I try to see where he went but after walking a few steps, I then realize I just stepped into my kitchen. There at the sink is my Math Teacher ( Dunno what he was doing ). He turns around and greets me, then pulls this mask out of a cabinet, he puts on my face and I feel powerless and only able to talk. He then asks me questions about all the bad things we did to him. I reply "I dunno what your talking about I swear!". So he takes the mask off my face and I am able to move. I then do another location switch ( Dunno Why ) and see im in my basement walking around the halls of it ( I have a huge basement, around 10 rooms + work-out room + Pool table room ). I then see labels on doors that i have never seen before, but appear to be in my basement. "Butcher Room" "Butcher Waiting Room" They both read. As i opened the door to the "Butcher Room" I see its a big white room with blood stains scrambled all over the wall, and legs , arms, heads, etc. I then see what happened in the past and saw my math teacher took my friends and butchered them. I go to the other room and see a red room with chairs that are out of place, as if there was a struggle. Then ( You guessed it ) I have another location switch but appear in the third person view. I see myself standing between the rooms just standing there. I then look over my souless's body's shoulder and see my math teacher coming down with a butcher knife. I then panic and run into myself which makes me in first person view now. I dont look behind myself, I only remember wishing I would wake up, and I did.
