I used to have a recurring plane crash theme in my dreams. It was random and sporadic. The criteria (such as when the crash happened, what type of plane, who I was with) all that would change from dream to dream.

On only one occasion did I "die" and was waiting to go to "heaven"... Coincidentally, the waiting area was the RiverWalk behind the RenCen in Detroit... Sure, Canada is across the river, and while it IS nice, it is not "heaven"...

And on the last one of such dreams, the plane did not end up crashing, and I have not had one since.

(And yes, I am aware of the interpretations behind these...)

And then there was the one time I dreamed about flying Business Class to HYD on a 747. Instead of seats, we had uncomfortable conference room style tables/chairs.
