Dean's dreams are actually attacks from faerie

[bratfarrar]

Relevant facts about the fic I'm looking for:

• I'm 98% sure it's set post-removal of the mark of Cain


• Dean's having nightmares, but they don't happen if he sleeps next to Sam


• They're actually attacks on him by faerie, who are coming after him because of his escape back in "Clap Your Hands"


• They use dream root so that Sam can walk into Dean's faerie-induced nightmares and help him fight back against the faerie


• In the end, they're able to force the faeries into corporal form, and fight them off that way


• It was on the longer side--I think it was split into two parts


• It's either smarmy gen, or slow-burn wincest--don't remember which for sure.

Thanks!
