SOPRANOS LAST DINER scene Tony's DREAM? Hallucination? Imagination? He really died / was SHOT in his SLEEP?

I am almost sure that the last scene in the Diner was in Tony Soprano's DREAM, or a hallucination, or his 'imagination' while he was sleeping in maybe the safe house in episode # 85 which was the last episode right before #86, the finale. Does anyone agree this could be possible? Most of the things that happened in that last Diner scene seemed SURREAL, & not reality ESPECIALLY how Chase photographed each of them in a solo shot opening their mouths WIDE to pop in the onion rings like COMMUNION WAFERS, & at the the beginning of scene, when Tony walked into the diner, the '"DREAM'' song was playing [forgot the title]. Also that Meadow was delayed because of her parking, & that also indicated that it was in Tony's mind to avoid her being in any gunfire or what he was really FEARING might happen. I feel he was controlling that in his dream or imagination since SHE was his favorite & many more things in that last scene that weren't REALITY. I think he died in his SLEEP when blacked out
