Nightmare

(This is all told from Stanford's perspective.)

I open my eyes to a pitch black room, I look around me to try and figure out where I am but fail miserably. In a attempt to escape, I take off running to my left but I'm stopped by a big metal object, blocking my path. I look up, it was the portal. Through the blue window out came, Stanley. He just stood there and stared at me.
"Stanley!" I run up to him, attempting to rap my arms around him but was quickly pushed away.
"What do you think your doing?! Why would you want some kind of demon hugging me?" He shouted?
"Stanley, I'm sorry. I'm so, so sorry." I yelp in desperation.
"Do you really think 'I'm sorry' is gonna cut it? No, no, no. Your not my brother, your a monster!" He screeched, pushing me off the ledge, the words 'monster' and 'demon' replayed in my head, I tried to shake the thought out but it wouldn't leave. I get back up and continue to run in the other direction, but blocking my path once again, Pa.
"What do you think your doing with your life? Creating deadly science experiments, slowly killing off your family one by one? I thought you would be better than that, but to my surprise your a disappointment, just like your brother. Your no son of mine." He scolded, 'disappointment' I began to sob, hearing those words from my father's mouth broke me. Covering my face with my arm, I dashed off once again. Again bumping into someone or something, removing my are to see, Fiddleford. Instead of the one I remember from all those years ago, there stood a crazed, scruffy man. He shakily picked up his arm, pointing it at me,
"Yo-Y-You d-did this, you arrogant barbarian!" He uttered, 'arrogant barbarian' was I that bad? As the routine goes and began to run again, there stopping me in my tracks was, Crampelter.
"Haha! Look at this dork! You became such a selfish, self-centred animal! You really think your family and friends would accept your weak apologies? No wonder they all abandoned you!" He cackled, 'selfish' 'self-centred' 'animal' I set off, faster than ever hoping this living hell would be over. Oh boy, I was wrong. I ran face first into a mirror, I rubbed my head as I began to gain my balance again. I looked at myself, I seemed normal, for about a minute before my reflection began to morph. It sprouted devil horns and a tail, from it's normal pale complexion it went as black as a shadow. It opened it's eyes, thin, slit pupils with glowing yellow scleras. It smiled wide at me, just at that second I woke up in a cold sweat. I breathed heavily, thank god it was just a nightmare.

But I began to think, am I a monster?
