They occured in two ways:
1. I would be chilling and someone would go bad or approach me and I would struggle. Eventually i would kill them with something nearby or just snap
their neck.
2. Someone would be chasing me. Eventually we'd stop, in a corner or something. We would fight and I would use my strength to kill them somehow.
What I figured out is that it wasn't really that I didn't like someone, but that I was afraid. Afraid of something, but it was certainly linked to
an uncertainity. What I find intersting is that you have a recuperative aspect to your dream by looking after your friend. The dream didnt end when
you killed someone, you moved on to a different part. I would look hard for some kind of physical or mental uncertainity in your life.
btw, heheh, I no longer have those dreams. I had them in college when things were going much better than they are now. So these dreams are not
neccessary linked to physical hardship or stress.
