The things Sam had said bothered Castiel as much as the symbols he had shown him. Yet, as he tried to decipher the layers or meanings it could have he was distracted by thinking about what Sam had told him and asked.
His answer was the truth, he didn’t know what Dean’s feelings were about what had happened, what they’d done. He had seemed fine with things when Castiel had left, yet confronted by Sam, he had suddenly become uncomfortable and almost… angry?
This was the problem of not understanding the ins and outs of human emotions. He just got confused. It was not a state he enjoyed. He needed to focus on this hunt, but with his thoughts circling back to Sam’s words and Dean’s actions, he couldn’t. There was only one option. Castiel had to talk with Dean about this and alone, which would be difficult thanks to Sam.
The easiest and quickest solution was to appear in Dean’s dream while he slept. He could transport Dean to him, but if Sam woke with Dean gone there would be complications. In Dean’s dreams, they could be alone there and there was no need to worry about waking Sam.
He waited until he was certain Dean would be asleep, then slipped into his dreams.
