I had a dream

Did anyone else think that Heart of Darkness was very similar to the idea behind Inception. I am thinking specifically where Marlow says that he had his "choice of nightmares," and I think the movie is based on this same idea. When the movie comes to the final scene where the dreidel does not fall, I think this is a perfect example where Cobb decides he wants to live in a certain dream with his kids. We are left to decide if reality is a dream or not. I think the "reality" we see throughout the entire movie is not a dream, but its the one Cobb chooses. It's his nightmare.
