Cage

You are feeling restricted, confined, and restrained in a current relationship or business deal. Somebody may be keeping a short leash on you because you lack the freedom to act independently.
To dream that you are putting a wild animal into a cage signifies that you will succeed in overcoming your rivals and fears. It is also symbolic of your ability to control your animalistic rages and anger.
