Are humans matter.. or psyche?

well, we must first define matter and psyche
matter is everything that occupies space and has mass and weight
the psyche is the influence of thought, personality and behaviour of humans
now, if we had to decide one or another (not both, nor neither), i would decide humans are matter, because we are mostly mass and weight and occupy space. If we were only psyche, were would that be? Because we are matter, we do have a brain. We can think, do and be. If we were only psyche, were would we be? that will bring us in an existentialism crysis, because if there was no matter, this would all be a dream, or matter is not physical just like psyche, so physical things don't exist. We don't exist. Were are we?
So, we are definetely matter. Psyche doesn't change us at all. We are who we are because of our DNA and because of our experiences in life. If psyche is the influence to think, do and be, then what is our brain? Our brain does have conscience and unconsciousness and we have our personality because of our DNA and we are who we are because of that and because of our experiences that later become knowledges and wisdom. Psyche doesn't exist, psyche is a religion, psyche is impossible to feel, bear, sense. Even passion, the ignition that make us do what we do with or without reason, is called adrenaline, in small or big quantities, and its all a chemical process in our brain. PSYCHE DOES NOT EXIST!!
