Wahneinfall Wahneinfall is an alternate term for autochthonous delusions or delusional intuition. This is one of the types of primary delusions in which a firm belief comes into the individual's mind 'out of the blue' or as an intuition, hence called delusional intuition. Other types of primary delusions include delusional mood (or atmosphere), delusional (apophanous) perception and delusional memories. Care must be taken not to impugn an otherwise rational individual's instinctive aversion or inexpressible sense of or belief about a thing by dismissing it as Wahneinfall.
