I had a dream of me going home from a party then witnessing a cat walking over a hill and then start yelling at me and run towards me then i fall and the cat stabs me in the head with a knife?

I'm interested in the party at the start of the dream; Were you coming from someplace you were not supposed to be? The cat could be guilt or punishment for your wrongdoing.

On the other hand, the cat could be someone who was at the party - Kate or Catherine, perhaps? Or someone who wears "cat" jewelry? It feels to me as if somebody has gone or is going out of their way to cause you trouble. Because you say specifically that you are stabbed in the head, you may be feeling attacked in the intellect or in your way of thinking.
