Psychosis can cause people to interpret the world around them differently from other people.

They might hear voices, they might see things or feel, smell and even taste things that don’t exist.

They might also suffer delusions and believe others are conspiring to harm them.



  1. Hallucinations – where a person hears, sees and, in some cases, feels, smells or tastes things that aren’t there; a common hallucination is hearing voices
  2. Delusions – where a person has strong beliefs that aren’t shared by others; a common delusion is someone believing there is a conspiracy to harm them
  3. The combination of hallucinations and delusional thinking can cause severe distress and a change in behaviour. Experiencing the symptoms of psychosis is often referred to as having a psychotic episode.
