The first night of nightmares had been the worst, the most frightening. Castiel had never experienced anything like it before, any fear like it before. It had taken all his will power to stifle the scream that had lept into his lungs as he awoke. On the third night he had not been so lucky, the sream escaped him before he could stop it. After only a few seconds he heard feet padding on the floor outside the room, before the door opened and a shaft of light hit Cas's eyes. A gruff voice laden with sleep broke the heavy silence that had filled the room back up since the scream, "You okay, Cas?" Castiel didn't reply, he merely pulled the covers up to his chin and wiped the tears from his eyes. The green eyes gave him a knowing look, "Nightmares?" There was no reply but the answer was self evident. Cas heard the feet padding on the floor again before the bed creaked under the weight of another person. Blue eyes gave green ones a questioning look, only recieving a shrug in reply as Dean Winchester wrapped his arms around his fallen angel. There were no more nightmares that night.
This one is longer than the others but it got quite fluffy which is much more fun to write. Again, thank you for reading :)
