Once again, this thread is about the end of the movie, if you haven't seen it, don't scroll down till you do see it. If you haven't seen it, go into the movie and right at the beginning say to yourself "what is this entire movie was true/possible"
Okay So now that that is out of the way. What did everyone think of the end of it...
My theory is that he is still stuck in limbo and will be forever. He spins his totem to see if it is reality but when he sees his kids he just doesn't care anymore. They are wearing the same clothes they were wearing in his memory when he tried to change it so that he could see their faces. Once he finally does change that memory and is able to see their faces he accepts that as his reality whether or not it is actually reality. Also i think the fact that the totem spun for ever but still wobbled meant that he was still somewhere in the middle of reality and dreamworld.
Then again as I typed this I thought of a few reasons why he had to be in reality... That movie was wild, its crazy to think about if all of that was true or possible. My mind got fucked 5 ways sideways from that movie.
