People were standing in a line along a city street. The line was several blocks long. The people, quiet and well-behaved, were on the pavement rather than the sidewalk, blocking cross streets.
A tall, athletic looking young man was striding purposefully down the street in the opposite direction of the line, paying no attention to the people. He came to a blocked cross street and angled into the line, where there was a gap between two men.
As he crossed the line of people, the man was grabbed by an equally tall, equally athletic man, who literally picked him up and threw him to the ground across the sidewalk. The men, so much alike they could have been brothers, glared at each other. Then the first man got up, strode to the second man, picked HIM up and threw him to the ground.
Now the two squared off and started throwing punches, dancing around until they were on opposite sites of a huge oak tree. The tree was unusual in that all of its bark had been torn off, leaving it white and covered in what looked like scratches from bear claws.
The adversaries continued to try to hit each other around the tree. Finally, the man from the line reached into his backpack and pulled out a square of leather that contained some sort of bladed weapon. As he pulled it out, the other man reached around the tree in an attempted punch. The weapon -- somewhat accidentally -- lodged in his ribcage and a huge amount of blood sprayed out.
End of dream.
The people in line are Christians, dutifully following the religious rules. The man going against the flow is a non-believer, minding his own business. When he crosses the believers, there is a self-righteous indignation that sparks the fight.
Ultimately, the combatants are arrayed against each other around a tree that represents TRUTH. For generations, Christians and non-Christians have been ripping parts of the truth from this tree in self-serving attempts to "win" their arguments about religion.
The Christian, willing to win his point at all costs, draws out a particularly deadly shard of truth and kills the nonbeliever.
The lesson: When you tear anything away from truth, you are left with something that is only capable of doing harm.
The people in line are rank-and-file Christians, who go to church on Sundays and otherwise observe worldly values. The man walking against the flow is a rabid, evangelical follower of Christ, who is doing God's will and has no interest in whatever the nominal Christians are doing.
Those in line find this man's very existence an affront to their self-righteousness and deliberately attempt to snuff it out.
The tree represents Jesus. The whiteness is His innocence even after He has been scourged and crucified. The final death blow is a recapitulation of the crucifixion and the innocent blood once more covers those who most wanted to kill Him.
