This is what the movie is about!!!
After watching this film four times, I think I have an idea of what it means to me. The film is, in a sense, Purgatory. Our main character died in the fire that burnt down his company. He is in purgatory because he started the fire. Nearly everybody in the movie is lost, cant find someone, or stuck in the traffic jam.
Also think of the bar scene. The girl who cant get up probably broke her neck and died, now she is in purgatory. The guy throwing up at the bar probably died of some poison, also, everybody is yelling " Where are we at?!"
The main character confronts the dead of his past(train station)... To make a long entry short, in the last scene, They come to take him away...and by the looks of all the "demonlike" figures that stand up in the field and the other characters who come towards him, they`re taking him to Hell.!!!!!
