Digging dead body in my dream?

im with two african male kids... i know we are with some other people they are militants or something... the two boy keeps on chanting something like some militants or terrorist chants... one boy water downed the soil with a hose i get the impression that we need to dig something as there are marks on the ground where we are supposed to dig... my shovel broke because the soil is hard so i wet it with water... after a while i dug a wrist watch... i gave it to one of the boys then when i look theres a dead body with no head on the area im digging the boy said the head of the dead guy turned to stone... so what does it means..
