hallucinations

Hallucinations refer to experiences where a person perceives something that isn't actually present in reality. This can involve seeing, hearing, smelling, or feeling things that do not exist outside of their mind. Hallucinations are often associated with mental disorders, substance use, or extreme stress, but can also occur in healthy individuals under certain conditions, such as sleep deprivation. They highlight the complex ways our brains process information and can be disorienting or frightening for those who experience them, as they challenge one's understanding of reality.
