By the way, Frame of Mind had a similar story to Inception, and, despite it's very limited time and budget, almost worked better. By having the play be confused with reality, and having both the entire thing set in an insane asylum really made the viewer question things!
Question what? That the entire TV series occured in Riker's mind? Uh-uh. It was pretty obvious to anyone who "knows how TV works" that the whole episode was a dream/illusion. Not saying it wasn't a great episode, it was, but there was never a doubt in my mind that Riker was having a dream or was having something done to him. Unfortuantly, that's just the "flaw" in doing episodes like that in a TV series, the viewer knows
that the whole series isn't going to be rendered null in the middle of it's season and with more seasons (and possibly movies) in the future.
As for TBC's take on what dreams "really are" as an argument about what the dreams were in this movie:
You're comparing apples and oranges. What you're pretty much saying is that "Star Trek isn't about space travel because Einstein and modern physicists say faster-than-light travel is impossible if not just wildly impractical from an energy standpoint."
about dreams because in Inception's universe dreams do
occur the way they're suggested. That it doesn't line up with what present-day understanding of what dreams are is irrelevant. In the movie this "is" how dreams are.
