Destiel - Nightmares

It was two nights after all the angels fell from Heaven. It took Cas 17 hours to find Dean in an abandoned house with Sam no where in sight. Dean, having nightmares and loneliness issues, was sat on the sofa, fiddling with a packet of matches with dark rings under his eyes. Cas knocked on the door and entered, only to be hugged as tightly as a terrified child hugs their comfort toy. Cas kissed Deans cheek and whispered "Its alright, you can sleep. They wont hurt you now, I wont let them.". Cas led Dean onto the sofa where Dean rested his head upon Cas' chest and fell asleep, not getting a single nightmare that night.
