I think that my dreams are subconsciously brainwashing me and magnifying my psychological problems. I suspect that certain conscious feelings result in dreams that then subconsciously brainwash me to have stronger conscious feelings. Is this plausible that the dreams are actually feeding back to make my psychological problems worse? I often feel like my reactions to situations are beyond my conscious control and completely out of proportion to reality.

Specifically:

(1) I've noticed waking up and realizing that my dream was very negative about the value of life. (This week my dream was like a South Park cartoon. It was actually kind of funny and cute, but it was also gross just like South Park.) I think these kinds of dreams make me depressed the following day.

(2) My brother and I are business partners and I literally cannot stand to even look at him or hear his voice. Sometimes I wake up and realize that I was dreaming about my brother except that all his negative features were ridiculously magnified. My conscious behavior around my brother is involuntary anger and disgust that is triggered by simply seeing my brother's face.

Does this theory of dream brainwashing make sense to anybody? If so, what do psychiatrists call this phenomena and how do I fix it?
