(Relax, there is no end date in sight just yet.)

But Ackles can one-up that feeling with a dream he had.

I can see it right now, Ackles says.

Its just one scene.

Think: Middle America, Big Sky country.

I drive up in the Impala, and I park in the middle of the intersection.

Theres nobody for miles.

Its a guy on a motorbike.

And we never really see his face.

Hes got a helmet on.

Because I dont need the extra seat anymore.

And I even have the soundtrack in my head.

There were no words spoken.

I had this swelling score.

It was like some Robert Zemeckis film.

When its all said and done, its going to be tough.

Im going to lose several friends.
