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.

Philosophy contributes to hallucinations research in three distinct ways. Phenomenology provides a sophisticated, critical understanding of the lived experience of hallucinations. Philosophy of cognitive science enables big-picture theorizing, synthesis of ideas, and critical engagement with new paradigms. Philosophy of science and psychiatry raises theoretically informed questions about diagnosis and categorization. These contributions reflect philosophy's methodological variety and its relevance to hallucinations researchers.

Among people with psychosis, visions most often depict people who behave and appear real, making them indistinguishable from actual perception. In interviews with twelve participants, three key features emerged: the content of visions is typically people; these people act coherently, often speaking or touching the observer; and the visions possess a compelling authenticity. This combination explains why visions are so absorbing and distressing, and the framework of Content, Coherence, and Quality offers clinicians a practical way to explore these experiences.
