Yesterday in my dream! I dreamed that I received a casting call from the director in California, they offering me an acting job and wants me to move as soon as possible before the movie start to role; (I'm current enrolled for class now) I was so excited but the problem is that my parent got home from the groceries. I told them that they were wrong about me (as they said negative words like: you're stupid, you're ugly, you're fat, you don't have a look etc) then I prove them wrong and then my mom and I got into an argument about the wrong that she did me! so my dad got his cane and abuse me, and for that I got mad and ending up murder him with a big knife chopping from his head down. I hope this dreams is not an punishment.
I think this dream could be about your own anxieties. Your parents saying all those negative things about you represent the part of yourself that is worried that you won't do well in the class and that you won't succeed at what you want to. It would be normal to have those kinds of worries. You murdering your father in the dream is just the confident part of yourself destroying all those negative thoughts, which is a good thing. Do/did your parents speak to you in that negative way in waking life?
