Hi so I'm actually looking for 3 different fics. Please any help or recs (no problem with self recs)

1. fallingcas!Dean Cas dreams for the first time and its of Dean
2. Cas marks Dean as he raises him even though he shoulden't
3. LOTR crossover where the boys are dropped into middle earth

First fic

Falling Cas dreams destiel slash. 

I'm looking for a fic I read where Cas was falling and went to sleep for the first time and all he can see are graphic dreams of himself and Dean. He's overwhelmed and run's into Dean and Sam's room. Dean assumes he's had a nightmare and Cas goes along with this lie saying that he dreamed of Lucifer. 

Please Please help me find this I've been looking all over the internet for this. 

Second fic Destiel

It was a story that had a wonderfully detailed account of Dean being pulled from the Pit by Cas. It dealt with Cas marking Dean. At one point Cas admitts that he was never supposed to mark Dean and that it should have been Michael but Dean wouldn't let go of Cas. 

Third Fic Crossover

I'm looking for a Lord Of The Rings/ Supernatural crossover. Anything where the boys are dropped into Middle Earth. Please no Crack fics. I'm looking for a serious fic where the boys are in middle earth and seem to be stuck there and become involved with the events transpiring like going into battle. Absolutely No Wincest! I would prefer a fic that includes Castiel and any that involve Destiel will be properly venerated as divine. 

I throw myself at the mercy of the Internet for your help.
