Hallucination

The Temptation of St. Anthony, detail, Isenheim Altarpiece, Mathias Grünewald, 1515, hallucinations caused by ergot

Hallucination (from Latin: (h)alūcinātio "thoughtless talk, reverie"; from Greek: ἀλύειν halýein "to be out of one's mind") is a perception of a sensory area without a stimulus basis. This means, for example, that non-existent objects are seen, or voices are heard without anyone speaking. Hallucinations can affect all sensory areas. In an illusion, on the other hand, a real object is perceived in a different way: An actually existing fixed object appears to move or faces appear to be recognisable in irregular patterns.

By definition, a hallucination has the character of reality for the hallucinating person or cannot be distinguished from reality. In contrast, in a pseudohallucination, the person realises that it is not a real perception. Pseudohallucinations can also occur during overtiredness and half-sleep.
