Dean woke up screaming.
„What's happened?" asked concerned Cas.
Dean bounced on a bed and looked frightened at an angel.
„How did you…!?"
„It's a long story." Cas murmured. He rubbed his forehed. „What's happened?" Cas repeated.
Dean sat and buried his face in his hands. Castiel was still patiently standing in the courner.
„I had a nightmire"
„Again?"
Winchester sighed loudly. He still saw a Sam's face splashed in blood and a knife in his hand.
„Tell me about it".
„It's not very pleasant for me" said Dean and looked little agitated at Cas.
„Just tell me," pressed Cas.
Dean couldn't withstand any longer. He began to tell him about Sam who still hadn't his soul back and wanted Dean's death. Winchester described every wound, quoted every word, showed every hit. Castiel was listening. He just wanted Dean to feel better.
„…then I woke up and saw you," ended Dean with a strong relief. He releted his nightmire for the first time in his life.
„I'm so sorry," said sadly Castiel. „Are you still sleepy?"
Dean stretched his sore muscles.
„No," he murmured. „But I need sleep".
Castiel touched Dean's forehead. Winchester heavily flopped at his pillow.
Cas hoped that he helped. He just loved Dean and wanted him to feel safe.
