Are we all just figments of Tommy Westphall's mind?

Remember the show St. Elsewhere?  It was a tv show about a hospital in Boston that ran from October 1982 to May 1988.  The show was chock full of 80's tv stars...

I believe I see Flounder, Deal or No Deal Howie, Mr. Shoop, Denzel Washington, Ed Bagley Jr., Dick Cheney and the lead singer from El DeBarge... so like I said chock full of 80s TV star power.  

Speaking of El DeBarge...  Who's Johnny?  http://www.youtube.com/watch?v=6jaWPQ3Z7FE

Getting back to the meat of this blog...

So, when all was said and done with St. Elsewhere the writer's ended the series like this:

The final episode of St. Elsewhere, known as "The Last One", ended in a context different from every other episode of the series. As the viewer pans away from snow beginning to fall at St. Eligius, the scene changes to Donald Westphall's autistic son Tommy, and Daniel Auschlander in an apartment building. Westphall arrives home from a day of work, and it is clear that he works in construction from the uniform he wears and from a conversation in this scene. "Auschlander" is revealed to be Donald's father, and thus Tommy's grandfather. Donald laments to his father, "I don't understand this autism thing, Pop. Here's my son. I talk to him. I don't even know if he can hear me, because he sits there, all day long, in his own world, staring at that toy. What's he thinkin' about?" (A reference to the rock opera, Tommy by The Who) The toy is revealed to be a snow globe with a replica of St. Eligius inside. Tommy shakes the snow globe, and is told by his father to come and wash his hands. Donald Westphall places the snow globe on the family's television set and walks into the kitchen and the camera closes in on the snow globe.

The common assumption is that the entire series took place within the autistic kid's mind, Tommy Westphall.

Now I am not breaking any new ground here, this is something that's been pondered by many but if St. Elsewhere is simply a figment of Tommy Westphall's imagination then the characters within  that show would be also...  Now, when these same exact characters appear on other TV shows that would mean that that show had to take place within his mind as well correct?  

Let me elaborate some, the character Dr. Turner from St. Elsewhere found herself being investigated for murder on Homicide: Life of the Street, it was a fictional cross-over.  If the character Dr. Turner only existed in Tommy's mind and every "action" of her's then had to have, then wouldn't that mean her being investigated for murder too?  If you say yes, as I do, then going a step further wouldn't that mean that since the characters of Homicide: Life on Street were in fact interacting with her, that they also are a part of Tommy's imagination?

Okay on that part? 

Now I am going to move a little fast here but trust me on it all... I will provide references.

Craig Westphall from St. Elsewhere visited the bar Cheers on one episode, Norm and Carla are included in the episode.  Now Going on what we've already agreed upon then wouldn't that mean Norm and Carla are also a part of the Tommy Westphall universe?  Yes... now let's move really fast....  Cheers >>> Fraiser >>>Caroline in the City>>>> The Single Guy>>>> Friends>>>>> Joey  

As it turns out, most network TV takes place in Tommy Westphall's mind, from Sabrina the Teenage Witch to Hill Street Blues, from the X-Files to The Ropers, from Bones to Hogan's Heros.

Here's the long versions of the proof: Show by Show link to 282 shows from Tommy Westphall's Universe and http://home.vicnet.net.au/~kwgow/crossovers(scaled).jpg,
