hallucination

Hallucination occurs when the brain perceives things that aren’t actually present, effectively creating false sensory experiences. This can involve any of the senses—seeing, hearing, smelling, tasting, or feeling something that isn’t there. Hallucinations can result from various factors such as mental health conditions, neurological issues, lack of sleep, or substance use. They are sensory perceptions without external stimuli, making the individual believe they are real. Understanding that hallucinations are perceptual errors helps in addressing underlying causes and providing appropriate support or treatment.
