In the film Jacob's Ladder (1991) there are two character's that die in car bombs/explosions. This leads Jacob and his other Vietnam War buddies to start to believe there is a government conspiracy to cover up things that were done to them in the war. Depending on one's interpretation of the movie however, we later learn that...
Jacob actually died in Vietnam and the entire film was either a hallucination or time spent in purgatory.
If this is the case then I assume there is some sort of significance or symbolism behind the car bombs but what could it be?
