Hi c_n12.
I have experienced this type of thing to an extent.
In waking live I am a very calm person that rarely resorts to violence and I have never picked a fight or thrown the first punch. But in the past when someone has initiated a fight with me I have removed all restraints for only a couple of seconds. This has resulted in a few cracked ribs and sore faces.(A feat I am NOT proud of). And I have always made sure they are OK afterwards.
In my dreams however, if someone initiates, the restraints come off and stay off.In the last dream this happened a guy thought I was talking to his girlfriend.He tried to fight me so I brutally bashed him in front of his girlfriend. And i didn’t stop until his torso was laying in several pieces around some train tracks.
As for your uncontrollable anger, I’m not sure as to what is behind it but it may be a similar problem to mine.
I hope this helps in some way.
