Why not? Destiel & Sam/Jess (high school AU)

Its own prison

Cas

It's dark. I can't see anything. It's cold and I have this intense feeling of loneliness and isolation. I get a strong urge to cry, but I can't find it in me too. I'm standing in nothingness.

"Castiel," a voice whispers from the darkness. It sends chill down my whole body. I want to run as far away from it as possible, but I can't figure out which direction it came from. It sounds like it's coming from all around me.

"Who are you?!" I yell out. I'm suddenly angry. Furious, I feel like I want to kill someone. I want to take a knife and dig it through their heart. I want to make them suffer. The voice laughs.

"You are just like me." They say. My anger intensified. I want to take a blade and carve into human flesh. Someone, someone like dean. I want to put the blade into dean's chest and carve out his heart while I watch the life leave his eyes.

"Where am I?!" I yell out. I feel the voice surrounding me. I feel like my chest is closing in. I fall to the ground. My head is pounding. I scream at the pain. The voice scoffs.

"You are in my prison, Castiel." It says. Prison. I remember sam and Jessica. I suddenly snap out of my murderous rage. I am disgusted with myself. This place, it, it's making feel things. I need to get out.

"What am I doing here?" I ask, feeling hopeless. I feel like everyone has abandoned me.

"I am going to save you." It says. I breath heavily, trying to catch my breath. The emotions are so overwhelming, I feel the tears start to fall.

"From what?" I call out. I look around in the darkness, in attempt to pin-point the voice, but it's no use.

"The crash, my dear Castiel." That's right. The crash. I remember now. I was in the car when we were hit. I was with jo. If I was in the car, how did I get here?

"Why? Why would you do that?" I ask. Confusion, anger, sadness, hopelessness, and nothingness is all sweeping over me at once. I feel my eyes start to get fuzzy. I can't take all this. I want it to all stop. I want to die.

"I can't let you die yet, you still have work to do." It answers. I struggle to breathe, I feel as if I am floating on air, yet at the same time I'm made of lead.

"What are you talking about?" I say between breaths.

"Castiel, you are my son. You are the only thing important to me." I try to absorb what the voice has said, but I am too overwhelmed with emotions. I can barely comprehend a word it is saying.

"What- how-?" I can't even get out an entire sentence anymore. I feel drained of all my energy.

"That is- you'll have to say goodbye to your girlfriend." It laughed at my pathetic ness. I wanted to tear it apart, but I couldn't even get my legs to stand.

"Who? Who are you talking about?" I yelled. It said girlfriend. What if he is talking about dean?

"Jooo-annnnaaaaa" it taunted. I wanted to scream in rage, but I couldn't find my voice anymore. Once again, it laughed it's sickening laugh.

"In order to bring you back, another life must be taken." It explained. That doesn't make any sense, angles do it all the time! "Ah, but there is where you're wrong, Castiel. Why do you think angels run a heaven and hell?" It was as if it was reading my mind, it couldn't do that, could it? "It's because they know that when they revive anyone back to life, another is taken, weather they deserve it or not."

It's starting to piece together in my head. It wants to take jo's life for mine. No.

"No!" I yelled out. I suddenly felt a surge of adrenaline. "I won't let you!" Suddenly, an immense, white light started to appear. I couldn't figure out where it was coming from. It was all around me. Then I realized something. It was coming from me.

The light expanded, it was so bright, I couldn't see anything inside of it, but I'm sure there's nothing.

I feel strong again, no longer sad or angry, I feel unstoppable. I don't hear the voice anymore, maybe I scared it away. I look around in the lightness, it's like I'm in a shining star.

This has to be a dream. A terrible, horrible dream. Suddenly, The voice chuckled.

"I'll see you soon, Castiel." Everytime it said my name, a layer of fear formed. The light started to dye down a little. I tried to back away, terrified of being back in the darkness, but that only made it dim quicker. I trembled, and my legs started shaking.

It stuck it's face into what was left of the light. "Boo!" It roared. It had big, Black horns, and red, glowing eyes. The skin was black as night, and it looked scaley and rough. The teeth were sharp as knives, and coated in yellow and black gunk. Saliva flowed from its mouth.

I gasped and fell back. Suddenly, I was falling down a pit, one that felt like it would never end. I was engulfed in darkness and emptiness. 

My eyes fly open, and I see light. It's so bright, it hurts my head. When my eyes adjust, I see I'm in the motel room. I've never been happier to see a motel room. Dean is standing next to me, he turns to me.

"Cas," He says, trying to calm me down. My whole body hurts so bad. I remember jo. That was no dream. No.

"Dean," I started to say, but something was stuck in my throat. I felt like my throat was on fire. Dean hushed me.

"Don't talk, You need to go back to sleep." I was getting frustrated. I needed him to save jo, and sleep was the last thing I needed. I shook my head.

"Jo," I tried again, but I couldn't finish. He smirked.

"Jo is fine, she will be okay." He said. No! No you need to listen to me! That's what I wanted to say.

"No... no, please, go to her. She is..." is what came out instead. Anna walked up to and stuck a needle in my neck. Damnit, no!

"It's going to kill her..." I said under my breath right before I fell into a deep sleep.
