Hi everybody!

I am looking for a specific fic. It is really old. One of the brothers, I think it was Sam is looking for a way to bring Dean back from death. Sam succeeds (I think he made a deal), but for a long time Dean is just a dead body. I remember Sam moving the body into a house, it was winter time. After a long time Dean's heart starts beating, later he starts breathing. Then he even starts moving.Sam goes jogging with him to keep Dean active even if his mind is still missing. This process of coming back to life was really long, months or even years. I remember Sam was really scared to leave Dean's body alone. I might have listened to it as a podfic. It was truly amazing and now I can't seem to find it. Please help!
