This is not Dean in a coma exactly but he is in a totally different world than what he knew before he was kidnapped and taken to Heaven...not sure if it wets the same appitite or not, but I thought I would toss it your way in case....

In the Fields of Oberon
Genre: Slash eventual M/M
Pairings: Dean/OMCs, Dean/Sam
Rating: NC-17
Summary: Sam and Dean were on a hunt when everything went kind of wrong. Dean tripped and fell into a fairy ring and woke up in the fields of Oberon, and now instead of being the hunter he was the hunted.

It's not Life on Mars with Dean in a coma, but he does fall through a fairy ring and wake up in another world and end up with amnesia ??

Thank I will read
