Hallucinations are often studied as isolated symptoms, but this review argues that they emerge from a broader set of changes in cognition, perception, selfhood, time, interpersonal experience, and embodiment. The authors suggest that grouping different hallucinatory experiences under a single definition may obscure meaningful differences in their causes and subjective qualities. They review phenomenological and neurocognitive theories and the role of trauma, proposing that hallucinations are an equifinal outcome of multiple genetic, neurocognitive, subjective, and social processes. Future research should incorporate a wider range of experiential alterations, and clinical practice should use phenomenologically responsive techniques and develop targeted therapies.
