I am looking for a specific fic, unfortunately I don't have a lot to go on. I assume it's hurt!Dean and Dean/Sam because that's just what I usually like.
The only thing I remember is a young Dean having nightmares that felt so real that he never knew if he was asleep or awake when he had them. He sometimes thought he woke up just to notice that he's still trapped in his dream. But whenever he really woke up, he knew it was real and he's only dreaming before. The author described this so beautifully, this scene is stuck in my head.
All this is more of an introduction to the whole story, so don't wrack your head about fics with a similar premise. It's not a big part in the story.
This one's probably quite well-known, I know I have read it a few times myself and I'll have a 'Duh' moment when somebody points it out to me.
...On second thought it's possible that it's actually j2 but I have a feeling it's not.
Thanks in advance!
