Claustrophobia, the cycle of depression", arises from the need to transform a sensation into a picture, a state of mind devoid of organic or pathological causes, deriving from a particular awareness of our existential reality.
This represent a trip into my mind, isn't just a representation of my thoughts, Claustrophobia is like a documentary of my psychical state.

The hopeless dream of being - not seeming, but being. At every waking moment, alert. Every inflection and every gesture a lie, every smile a grimace. Suicide? No, too vulgar. But you can refuse to move, refuse to talk, so that you don't have to lie. You can shut yourself in. (Persona 1966)
