Dreaming of elbows mean protective weapons at your disposal. When you fold your hands across your chest and extend both elbows, you defenses are at its peak and no one will find you approachable.
This can mean that your ability to advance is capped by your unwillingness to share and be accommodating to you peers.
Dreaming of an enemy represents part of your life that you fear and beyond your control. The more you think about these situations, it starts to take on a physical form of an enemy that has always been in the back of your mind. Think about unsheathing your weapons and tools to take immediate action against the enemies troubling your dreams.
