ok, so I was gonna rec a fic earlier, but now I can't find it, so I need help.   I'm pretty sure it happened in salvation, and John sees Sam having a vision and he shakes him to try to wake him up (pretty sure he doesn't know about the visions.)  So yeah, then Dean starts getting protective cause John wants to ask questions right away and Sam just needs to pass out.  Ring any bells?   i'll love you forever
