It didn't really have anything to say about anything, it didn't question the morality of going into someones mind and completely changing their entire nature of being. It had a few interesting observations like not realising when a dream starts and some nice visual flair but aside from trying to keep track of the narrative, there wasn't much to engage with.
Sorry for the late response, computer at home got messed up.
I do somewhat agree that it wouldn't have hurt the film had the morality of the situations been explored more. Although i But then, it's one of those things where it's probably best to compare that aspect with Nolan's body of work in order to let it slide. Nolan's protagonists tends to be very selfish individuals driven to do the impossible with very little regard to others and the overall consequences. Not trying to make excuses for the lack of morality questioning, but I do think it helps to look to those films as a reference point.
It's also one of those things where people either get something out of it, or they don't, really. It also might be one of those things where you've seen other foreign flicks that may have dealt with similar themes whereas I haven't seen such a film. I do know that
Paprika is supposed to be similar to
Inception.
You ask, "What does this have with Inception?" I'm not totally sure, but one thing which Inception does seem to feed off is that dreams are pumped-up reality and somehow more realistic (to the dreamer) than reality. In Inception, there are many levels of dreams and "realities", and I believe that Nolan kept everything pretty much clear, especially within a thriller/mystery plot. My dreams don't especially cry out to me for a specific answer. They seem to cry out to just be experienced and experienced HARD. I'm sure if Nolan wants to craft a deeper, more-esoteric study about dreams, then he probably could do it. He just may have to move at a quick pace because I think that Sarah and I can get a(n albeit low-budget) flick on the subject out rather quickly which might appeal to some dreamers and "elitists" (HA!) equally. It'll probably gross about $12.95 but somebody will champion it anyway, and Underachieving Bums don't care about Big Bucks anyway.
I don't think any dream has a specific answer for anybody, mate. I do think that whatever emotions you are feeling with manifest itself in the subconcious, that much is obvious. The dreams I experience involve little guilt but desire more than anything, and fear, which is ridiculously hard to overcome. Since you can wake and go back into a dream state at will, I imagine you've experienced lucid dreaming? Had a couple of those experiences within the last several months, which I think may have been influenced by the film a bit. projectiles and Hulk style jumping were involved though.
But sometimes the cause of our dreams can take different forms we don't necessarily recognize or connect the dream to. Instead of working at an endless task, our anxiety may convert our on-the-job pressures into an image of being bogged down in the mud unable to move or drowning or some other problem--lost and searching for an escape or rescue.
I think this is true to an extent, but at the same time in order for us to dream about such an image, we have to have created it ourselves. More on this later gotta run.
