Positive symptoms highlight a change in your usual thinking process and can include delusions are false beliefs that are out of context with your usual cultural or social ideas. E. g, you may believe your movements are being controlled by someone else; hallucinations are when you hear voices that may speak directly to or about you even though there isn't anyone there. Visual hallucinations are when you see things that aren't there. You may have thought disorders can affect your thinking patterns and make speech difficult to follow. Together these symptoms are called psychosis.
