Visions are experiences in which a person perceives something visually that may not have an external source, or imagines outcomes as if seen. The term covers a broad range of phenomena, from perceptual experiences during wakefulness or sleep to metaphorical depictions of future possibilities. In scientific and clinical contexts, visions are distinguished by their source as either subjective percepts generated by the brain or culturally framed interpretations of meaningful experiences.

Perceptual visions can arise from normal sensory processing during dreams, hypnagogic or hypnopompic states, and from neurological or medical conditions such as migraine aura, seizures, delirium, or certain drug effects. In these cases, the visions are considered subjective phenomena produced by brain activity and do not necessarily imply external realities.

Religious, mystical, or cultural visions are interpreted within particular traditions as revelations, messages from deities or spirits, or guidance for behavior and belief. Throughout history such visions have influenced art, literature, religion, and social movements, and they continue to be cited in contemporary spiritual practices.

Visions can also refer to aspirational or strategic images of the future used to guide organizations, communities, and individuals. This usage emphasizes intention and planning as much as perception.

Differences between visions and clinical conditions are important: persistent, distressing, or disruptive visions may warrant medical evaluation to exclude underlying disorders. In general, visions are a broad category that encompasses perceptual phenomena, dream imagery, religious experiences, and future-oriented inspiration.
