Animosity 
To dream that there is animosity towards you indicates that you should reassess some aspect in your life and question your ethics and beliefs.
Anger
To dream that you are angry signifies vexation and regret within yourself. You push the negativity down and this reveals itself in anger toward others. Evaluate yourself.
Anger could have followed you into your dream from something that happened in waking hours. Dreams are a safe harbor with which to deal with these intense emotions. You simply haven't yet consciously accepted these strong angry emotions.
