The basic theme of an army dreams is a struggle against the forces of evil, against the monsters and demons that threaten us.
An army is an overwhelming force, irresistible and indestructible. It is a nameless power.
It can represent the forces of our emotions and our basic instincts as a whole.
If you dream about an army it is almost always connected with suffering from an internal conflict.
A marching army shows that you are about to be overwhelmed by your subconscious.
If there are two armies battling each other, it is a clear sign that there is conflict within the dreamer. There is a duality of thoughts, emotional stress and probably anxiety.
If you dream that an army is marching forward, you may believe that you will ultimately achieve success, but if it is retreating, it can be a sign that you are afraid that you are doomed to failure.
