I've been having a lot of strange dreams recently and they've all had the same recurring theme.

I witness someone doing something horrible to an innocent person or group. It makes me so angry and disgusted I immediately make a move to put a stop to it or seek vengeance for the innocent party. Yet despite all my efforts, nothing I do can change anything that has happened. Nor can I avenge the people that were put through so much suffering. Then I'm jolted awake from throwing one last punch or kick in my sleep.

What could this mean? I know my subconscious is trying to tell me something but I can't tell what exactly. I know it must be important, though. I just don't have enough time these days to thoroughly analyze my dreams on my own.
