Psychosis changes the way a person thinks and acts. Consequently, people with psychotic symptoms have a distorted perception of the world and lose touch with a shared reality with the general population.     Some people may have episodes of psychosis where it comes and goes, while for others, psychosis becomes stable over time. These psychotic symptoms include:     Thought Disorder (Disorganized Thinking) Unusual or illogical thoughts mark this symptom. People with thought disorders may experience impaired communication because their speech comprises meaningless and unconnected words.     Hallucinations   This symptom happens when a person sees, hears, or perceives things that are not there. Hallucinations may occur in any of the senses; the most common is hearing voices.    The family of someone who has schizophrenia may not always notice when they hear voices.   Movement Disorder (Abnormal Motor Behavior) A person with schizophrenia may exhibit abnormal body movement and motor responses. They may continually repeat an action, show unpredictable agitation, or assume bizarre posture.    Delusions This happens when a person shows strong attachment to beliefs that are not true and may seem irrational; it involves strong beliefs that have no basis in reality.   For example, people with delusions may believe that a celebrity is in love with them or that someone is trying to harm them.
