Pairings: Sam/Castiel, Sam/Castiel/Dean

Summary: Castiel had a terrible nightmare, but the good thing is that he has two beautiful hunters to make him feel better.

Warnings: kind of porn

Notes: It's the first time I write something like this, and I don't like much wincest, so sorry if it's missing some Dean/Sam interaction. I still hope you enjoy! The first chapter is only about Castiel's dream, so if you want to go directly to the good stuff, go to chapter 2.

Don't Dream, Reality Is Better

Castiel was walking with no course, in a place he didn't know; there was an old factory nearby, surrounded by some trees, but he didn't know exactly where he was. He knew he was helping Sam and Dean on a hunt, as he usual did since they had been together, but he didn't know where the brothers were, or what they were hunting. It all seemed a little strange…

Castiel walked towards the gray building, watchful to everything around him. As he got closer, he saw someone lied on the ground, and he stopped for a second, frozen, when he realized that person was Sam and that he was bleeding; so Castiel ran to him. Only when Castiel was very near Sam, he noticed the pool of red blood around him, not to mention the blood on his shirt and jacket. But Castiel didn't care, and kneeled down on the black ground covered by the red liquid, next to Sam.

Sam had the eyes closed and he didn't move. "Sam." Castiel called in hope, but also fear.

The young man opened his eyes slightly. "Cas." He answered in a low voice as he saw his angel, and smiled a little.

"Sam." Castiel said again as he caressed Sam's head, then passed the hand under Sam's head to the shoulders and lift him a little. Sam whined when he was moved, and instantly he brought a hand to his chest. Castiel grabbed Sam's bloodied hand tight, he couldn't help it, and pulled the hand down gently, so he could take a look at the wound where Sam had been stabbed.

Castiel placed a hand over the profound cut to heal it, but when he did it, nothing happened. Castiel closed his eyes and tried harder, once, twice… "No", he breathed out in fear. He saw Sam's eyes opening again, and looking in the half-open green eyes, Castiel confessed in a sad voice, "I can't heal you".

Sam opened his eyes a little more, not because of what Castiel told him, but because of the heartbreaking way the angel looked at him. "It's okay." Sam said in almost a whisper; he knew how Castiel felt, he had been through the same, so he had to make it as less painful for Castiel as possible.

Castiel shook his head. No…That couldn't be happening. He was the Winchesters' guardian, he always had been, and over the time he became so much more than that… an ally, a friend, and now a lover. They had been through so much… bad, terrible things, but they had also experienced wonderful moments together. But it was all going to end, because he was failing as a keeper, not because of Heaven's orders but because Castiel had made his personal task to protect the brothers he loved. And now he couldn't save Sam; as much as he wanted to do something, anything to save him, he couldn't. Castiel didn't know why his powers weren't working, perhaps it was the place, perhaps someone decided to cut his powers from Heaven… but why did it had to be in the moment he needed the most?

"Cas." Sam's weak voice made him focus in what was happening outside of himself. Only then Castiel noticed he was clutching Sam's arm and pulling his cold body tight against himself. "Go."

Castiel looked surprised and confused, but he made up his mind quickly. "No. I won't leave you." Castiel said as his eyes filled with tears.

"Go." Sam repeated, touching Castiel's shirt. "Go find Dean."

Sam was right; Dean was also there and he could need some help, but part of him still didn't want to leave Sam. "Tell Dean…" Sam forced to say despite the burning pain, "I love him." And tears rolled down Sam's face. He blinked a few times to take away the salty fluid from his eyes, so he could see Castiel clearly, although he wished he couldn't watch the angel's sorrowful face. "I love you too." He said in a whisper; his body was no longer responding to his command.

"Sam…" Castiel passed his free hand (the other one was on Sam's back supporting his body) by Sam's face, gently washing away the tears. He leaned down and kissed Sam's bloodied lips softly one last time. "I'll love you forever." Castiel said as he pulled back.

He waited to see Sam's green eyes opening again… but they didn't. Castiel bit his trembling lip and he held Sam's lifeless body tighter. He kept holding him, as his tears fell on Sam's shirt, until the beautiful glowing light of Sam's soul disappeared.

Then he tremulously laid the soulless body on the ground again, stood up and walked away, slowly, because he felt like he was leaving there a part of himself. Castiel tried to focus on finding Dean, he hoped Dean was alright, but if he was, he'll cease to be. How was he going to tell Dean that Sam had died, and that he couldn't bring him back, because if his powers had been taken from him, only God knows when, if ever, he'd have them back again. Castiel could already see Dean's agonizingly devastated face, as he walked around the factory.

As he made the curve, he saw Dean standing at the far end of the building. Castiel walked in his direction, without Dean noticing him; Dean was turned to the side, looking at something that was hidden behind the building. Castiel noticed Dean oddly quiet, and he immediately found out why when he heard a shot and saw Dean instantly falling on the ground.

Castiel felt like he had been stabbed in the ached part of his heart, that it was the only thing he had left because the rest had died with Sam. "DEEEAN!" Castiel screamed with tears in his eyes as he ran in Dean's direction. One had been terribly painful, but his two lovers, it was just unbearable. They made him what he was, they made him feel, taught him to fight, they were the reason why he did every single thing, even the bad things, and even after those bad things they still forgave him and showed the redemption road where the guilt was replaced by peace, and soon came the affection and love that bounded the three of them together in ways impossible to describe and understand… So, yes, they were him, and now he was nothing.

Castiel stopped when he got close to Dean, who had been shot in the head. At a far distance he still saw the person who had killed Dean running away, but Castiel didn't go after them. Instead, he kept staring at Dean's face, with eyes open but with no life, and for the first time Castiel felt so empty and lonely inside, lost in a large world that had no longer meaning to him…
