Usage Note

Hallucinant has shifted from its clinical root (causing hallucinations) to an emphatic colloquial intensifier meaning extraordinary or unbelievable — similar to English 'mind-blowing'. It is used positively and negatively: un talent hallucinant (incredible talent) or une erreur hallucinante (a staggering mistake). For an adverbial sense, de façon hallucinante is the natural choice.
