Eyes deceive completely
Visual hallucinations are false perceptions of things that aren't there—seeing people, animals, shapes, or lights with no external source.
They occur in various conditions: psychotic disorders, drug intoxication, severe fever, sleep deprivation, or neurological diseases like Parkinson's and Lewy body dementia.
