Gentalmen,
I met a man by chance who was shot in the forehead and had the back/top of his skull blown to pieces by a 7.62mm AJ-47 round and he enlightened me. He said that after he shot and killed 4 guys who ambushed his squad, he was reloading his MG and saw a muzzle flash. He said it hurt BRIGHTLY and quick then..... cold, cold, cold - water. In that time he said he saw Jesus. He also said he saw his squad attempting to talk to Jesus, but not all were accepted. (I tell you the truth on what he said, no embellishments- don't kill the messanger)
He said it felt like someone opened his body up and poured ice cold water into his wound and he felt it in every cubic inch of his body. He said he layed onconscience for 3.5 hours and woke up in a hospital.
The round didn't destroy most of his brain and he is alive, though with extremely severe PTSD and very much trouble concentrating. He also has a fear of cold water.
