Frustrations Exposed in Dreaming

I am a man in this dream, a doctor. Another doctor needs my help in order to make a man's death appear to be of natural causes. I am laying on a small hill, amoung a stand of autumn trees. Down the slope a short distance is a lake, large enough to have its own waves. There are three people swimming in this lake, a man and two women, a blonde and a thin brunette. Observing them, I pick up a brilliant red leaf, which has two holes in it. I let it rest on my face, and it contours to me, becomes the most beautiful and elegant mask. Through this mask I watch as the brunette swims further and further out, desperate and frantic almost in her motions, popping to the surface to take the briefest of breaths. The man is chasing her, he is more clumsy. He is getting tired. The blonde watches, smiling at me out of the corner of her eye. The man begins to drown, and the brunette leaves him. I am frozen in observance by the mask, it is a window behind which I am trapped. I retreat to my room. I become the brunette. The man I was is my lover. We are very in love. The blonde is trying to seduce my man. I come home and find her sleeping on our couch. She claims it is hers, that this is her home, not mine. I drag her from the room to the hallway by her hair. I smash her face into the concrete over and over again, feeling in myself the frustration of the man at the blondes psychotic obsession with him, and my own anger at her presumptions of the two of us. Her head bounces up and down on the concrete, I am mashing her face into mush, using her hair as leverage, smashing until my arms are so tired that I am forced to wake up.
