A risk factor for multimodal hallucinations is prior experience of unimodal hallucinations.<ref name=":0" /> In 90% cases of psychosis, a visual hallucination occurs in combination with another sensory modality, most often being auditory or somatic.<ref name=":0" /> In schizophrenia, multimodal hallucinations are twice as common as unimodal ones.<ref name=":0" />
