I feel moved to say that this dream is about an army knowing the voice of its commander - if the soldiers do not hear the commander's voice, they attack as though standing (position/strength) is the determination of who is the enemy, not faith in who the enemy will become (which we all were).
For example, take the anti-Christ, the Bible teaches both to beware anti-christs and to serve masters; but many in the faith can't wait to call the anti-Christ out and live in dread that they will have no power over him, when he comes. These are believers who do not have the patience of the Holy Spirit and the confidence of the Holy Spirit to anticipate his (the anti-christ's) fall. I'm not saying they're wrong - that's not my place - I am saying they are 'vulnerable'.
A true soldier of the faith, knows his own vulnerability before he knows his enemy's weakness (selah)
