A/N: I've had this idea for quite a while, but I haven't really had time to write it. Also, since I've been at my dads, I havent been able to upload it as he has no Internet. Yay. Which is also why I haven't updated in a while...
I'll hopefully be updating my humour fanfiction today too :D

Anyway, I hope you like it:)

This is set somewhere after 5x09 and before 5x11, though Kara shall actually appear in this fanfiction, though not in the same way she did in the series. Yet she may still have the same intentions. You'll just have to read to find out c:

Disclaimer: As much as I wish I did, I don't own Merlin.

Sorry for my awful writing and please forgive me if I make spelling and grammar mistakes. Feel free to critique/criticise anything; I really don't mind.

Mordred's eyes snapped open as he threw himself upright, breathing deeply. His hair clung to his forehead and tears flowed down his pale face. He quickly tried to wipe his eyes, but his quavering hands made it impossible to wipe his tears away. The terrible nightmare that he had just experienced was etched into his mind, each image as clear as the objects around him. Even though he was now awake, fear was still consuming him and he was terrified that those events could one day come to pass. He tried to think that they never would, but the dream had been so vivid and had felt so real.

"It's impossible." Mordred reassured himself aloud, taken back by how hoarse his voice was. He closed his eyes to concentrate on breathing, trying to calm himself down and picture another image. Yet all he could see when he closed his eyes was the flashing images of his nightmare.

Wiping his face once again, Mordred slipped out of bed and crossed his room to the window, hoping that fresh air could help. He opened the latch and slowly inhaled the clean air, trying to control his breathing once again. But he couldn't rid himself of the panic that came with the dream, which made it harder for him to stop hyperventilating.

"At least I've stopped crying." He thought to himself, trying to be somewhat optimistic. Optimism didn't calm him down though; his heart was still pounding rapidly against his chest and his hands were shaking. Even with the cold breeze blowing against his face, he was unable to breathe properly. With the panic consuming his brain, Mordred was unable to think which made it impossible for him to distract himself and calm down.

Not knowing what else he could do, Mordred decided to go for a short walk around the castle in hope to rid the nightmare from his mind. He knew that he would need an excuse for if he encountered any guards, but he could think of one when the time came. Trying to make himself look mildly presentable for his walk, Mordred placed a long blue cloak around his own shoulders and headed out his door, pulling the hood over his head.

Merlin slowly opened his eyes, trying to hold back the tears that were building in his throat. His lungs burned as he tried to gulp down the oxygen he so desperately needed. He'd experienced terrible nightmares before, but never one as clear and haunting as the one he'd just had. The flashing images from the dream were still replaying in his head, taking over his thoughts.

He closed his eyes again and turned on his side, trying to banish it from his mind. When it didn't disappear, Merlin dragged himself out of bed, whimpering as he thought of what he'd just seen. He dreaded to think that it could be real and kept reassuring himself that it was just a dream.

"I'll just make a remedy." Merlin said slowly, remembering how Gaius used to make ones for Morgana and had once made him several that had helped. "Then I can just forget this dream and get on with everything. It was just a dream."

Merlin continued to reassure himself that it was just a dream as he made his way across his room, but he couldn't shake the feeling that something was wrong. He had managed to steady his breathing, but he couldn't stop his hands from quavering rapidly or stop the tears that were building up in his eyes. The nightmare was like a ghost, haunting him with his every move.

He left his room silently, hoping he could mix the remedy right without having to wake Gaius and finally be free of the nightmare.

It's short, but it's just an introduction c:

I can promise you this now- Every event in the nightmare will come to pass so you will find out eventually everything that was in their dreams.

Also, I haven't decided some pairings, so which would you guys prefer: Arthur/Guinevere or Arthur/Merlin? You can also vote for Morgana/Merlin if you want.

I'll be updating this ASAP anyway. I hope you enjoyed it :)
