I'm looking for a fic where Sam and Dean switch bodies to save dean from going to hell.
They are at Bobby's and they start experiencing each other's memories (since some of these remained within the body).
And there's also some overlap in abilities/habits/(dis)likes, for example I remember Sam reading and not being able to do it anymore (because it was straining/boring to him etc), and I think the boys sticked to eating habits that their bodies (not their souls) were used to.
I hope I'm remebering correctly and not mixing stories.
Hope somebody knows the fic I'm talking about, I've been looking for quite some time. Thanks in advance!
