Re: Total Recall - Reviews, Grading, and duiscussions, SPOILERS
The more important about this dream vs. reality thing is, in the original film: if it is a dream implanted in Quaid's brain, why do we see scenes without Quaid? He wouldn't know about them, and if it's supposed to be a "realistic" vacation experience, he wouldn't dream those moments because he would not be there.
As I said above, it's not uncommon for movies that take place as a dream or a story being told to go outside the story teller's experiences and show us things they wouldn't know about. In which cases the audience
knows what's going on "behind the scenes" in story but the "dreamer" does not.
Out of hope.
