10 Best Movies About Unrealised Dreams

In the years since Inception's release, writer-director Christopher Nolan has been firm on his stance about the ending of the film: namely, that he won't ever explain it, and that it's up to each individual viewer to decide what they make of it - dream, or reality.

So it's a good thing that there's evidence to support both possible outcomes. Those who believe the ending - in which Dom Cobb is reunited with his children - is a reality can point to the fact that the spinning top does appear to waver a little (one of the film's rules is that if it falls over completely, Cobb is in the real world). On the other hand, people who believe the ending is still a dream can argue that because the spinning top used to belong to Cobb's wife, that it can't be trusted.

Whichever side of the coin you rest on, there is a possibility that Cobb hasn't fulfilled his dream of getting home to his kids by the time the credits roll. In fact, he could've been stuck within a dream - or multiple layers of dreams - for some time, lost in the labyrinth of his own mind.

While that's quite a bleak spin to put on something that looks extremely happy at face value (the cheeky smile on Cobb's son's face says it all), the interesting thing here is that Cobb doesn't care if he's dreaming or not: he thinks he's with his kids, and that's enough for him.

Even though, in reality, he could actually be hooked up to some machine, drunk on the happiness being fed to him by the images of family his mind has conjured up.
