My Nightmare

I stand over the mauled, bloody body of the Lucario. My eyes glistening a crimson glow, my aura sword shining in my hand, dripping blood. In the other hand, I hold a dark blue stone with an orange and yellow center, the Lucarionite.
"You should have given this to me, Rio. You would have suffered less." I say to the corpse, in a voice unlike my own. I reel back suddenly and close my eyes, holding one of my blood-covered hands to my head.
"Aaugh." I whisper in pain as my headache subsides. I open my eyes, which have returned to normal. I look down at Rio's body and drop the sword and stone and step back, my mouth hanging open in disbelief.
"N-n-no...." I whisper, tears brimming in my eyes. I step closer to the body of the Lucario I love, and I drop to my knees, burying my face into my hands.
"What have I done?" I sob loudly. The aura sword disappears along with the stone.
"Rio, why!?" I cry.
---------------------
"RIO, IM SORRY!" I scream as I shoot up in my bed. My tear-filled eyes open and I look around, panting. I'm not in the blood-filled cave with the dead body of Rio, I'm in my room. I feel cold sweat all over me and I lay back down, staring at the ceiling. I know I won't be able to fall back asleep. The dream is still fresh in my mind. It replays over and over and I start crying again. My heart starts pounding in my chest. 'What if Rio is hurt?' I think. I can't bear it anymore so I pull the covers off of me and I open my door and sprint down the hall.
----------------------
I knock again and again on Rio's door. Tears are still dripping from my eyes before I hear a click and Rio steps out of his room, bags under his eyes. He runs his tired eyes with a paw and looks at me. When he sees the tears on my face, his eyes grow more concerned.
"R-Rosie? What's wrong?" He asks me. I don't answer, but I stare at him, relief washing through me. He tilts his head, confused. I rush towards him and wrap my arms around his neck, crying into his shoulder. He stumbles a little bit, and then starts to hold me and run his fingers through my hair, asking me what's wrong and telling me it's okay.
---------------------
You may be wondering why I'm here.
I had a dream that you weren't here anymore.
I had to check on you,
Because I could never imagine my life without you.
Please, don't ever leave me.
