Although hallucinations are a feature of psychosis, they can present in non-psychotic disorders and may occur in non-pathological states. Jung argues that unconscious complexes underpin hallucinations and further observes that some of the symptoms of ‘hysteric’ patients - including hallucinations - were also common amongst patients with schizophrenia. However, the outward presentation of symptoms was markedly different for each patient group. Jung mobilises his complex theory to explain this difference. We argue that Jung’s understanding of hallucinations applies to contemporary healthcare; it frames how hallucinations may manifest in multiple conditions, not just psychosis. This brief report discusses Jung’s theories and their continued veracity in contemporary contexts.
