Psychosis (from the Greek ψυχή "psyche", for mind/soul, and -ωσις "-osis", for abnormal condition) means abnormal condition of the mind, and is a generic psychiatric term for a mental state often described as involving a "loss of contact with reality". People suffering from psychosis are described as psychotic. Psychosis is given to the more severe forms of psychiatric disorder, during which hallucinations and delusions and impaired insight may occur

Apparition

Paranoia: Being paranoid means being suspicious without reason, and believing that others are trying to harm you in some way. Everyone can be mistrustful at times, particularly if life hasn't treated him or her well. But people who are prone to paranoia always dread some forthcoming attack or betrayal. They are forever anticipating that something awful will happen, and trying to second-guess what their adversaries might do. They focus on their fears for the future, and take little account of the majority of times when the past has proved them wrong.

Mania

Psychosis has been chosen as the film title, or at least working title. This works as most thriller film titles relate to an event or person within the film. For instance, Inception is about the idea of Inception (placing an idea in the mind, literally a safe), The Dark Knight and Terminator 2 are the names of the protagonists (Terminator 2's subtitle, Judgement Day, refers to a supposed event within the film, which John Connor and the title character manage to stop.) and Psycho refers to Norman Bates. Psychosis, means having a condition of the mind, something the protagonist goes through after a traumatic experience, and hopes to cure by the narratives end.
