Supervising Correctional Populations Practice Test

Talking to someone who isn’t there is a hallucination—an experience of perceiving something sensory, often voices, without any external source. This is a perceptual event, not a belief, so it differs from a delusion (a fixed false belief) and from a misperception (misinterpreting real stimuli). It also isn’t a fantasy, which is voluntary imagination without a real sensory trigger. In practice, recognizing a hallucination is important for safety and care: respond calmly, avoid arguing about its reality, and involve mental health professionals for evaluation and support.
