Hey all! Been out of the fandom for a while but getting back into things (God Kripke knows I could never stay away for long!) Anyway, if you beautiful people could help me out with a few searches... ;)

1.  I remember reading a fic (pretty sure it was a case fic) that involved a building that allowed people to relive their memories but in doing so it took them away/ took away years from their life? The person who owned the place may have been getting it all for themselves? I want to say it was Sam, Dean, and someone else (maybe Cas, but I'm not sure) and they had to go through all the rooms, which I believe had numbers that corresponded with the age of the person at the time of the memory.

I remember a specific scene (though this could very well be from another fic entirely) of Dean as a teenager with his hair grown out longish and dancing around to Kiss' "I Wanna Rock And Roll All RIght", possibly carrying Sam on his back.

FOUND! It's Incubus by Crimson1 on ff.net.

2.  The second fic I'm looking for is a retelling of Cas pulling Dean out of hell. It was a really cool take on Cas rebuilding Dean's body from the earth, like he used straw for his hair and seashells for his nails and I think an apple for Dean's brain/heart? If I remember right, they were sitting in a field and Cas was telling Dean the story on how he rebuilt him and it was sort of fluffy. Possibly Destiel, but I'm not sure.

3.  The third was a coda to Dark Side of the Moon, with Dean seeing Sam's best memories and one of them was of Sam and Ruby together. Naturally, Dean freaked out and demanded to know what the hell this was doing in Sam's heaven, but then Sam said, "It's the day you came back from hell." I'm pretty sure it was a short, like under 1000 words, but it made me tear up and I'd love to find it.

4.  The fourth fic was written from Dean's POV and I just remember that Sam was judging Dean for sleeping with Anna, and Dean was mad because he didn't think it was wrong for Anna to forgive him for what he did in hell with her touch. I know that isn't much to go on, but it actually made me like Anna's character  (or at least understand her relationship with Dean) a hell of a lot more and I wanted to rec it to someone.

+1:  And I also have a general request: Are there any wincest fics based on the episode "Swap Meat"? Like Dean acting all seductive towards Gary!Sam and being frustrated when his advances are ignored? Or really just anything about that episode with a wincest twist. Preferably bottom!Dean but judging by my search, I'll go for anything.
