Umm.. technically? 'Bobby Ewing's death was a dream' wasn't an ending. It was a season finale reveal (the 9th). The actual series finale ending was JR appearing to have killed himself after being shown a world without JR by an "angel". Bobby uttered the final words of the series after hearing the gun shot and running into the room

"Oh my God..."

Of course in subsequent TV movies it was revealed JR did not kill himself but shot at a mirror at the last second.

Just saying'
