In Japanese, the concept of 'hallucination' is most commonly expressed with 幻覚 (genkaku), which covers sensory hallucinations. For drug-induced or psychedelic hallucinations, 幻覚症状 (genkaku shōjō) or 幻視 (genshi) for visual hallucinations are used. In casual or slang contexts, トリップ (torippu) from 'trip' is common. For AI 'hallucinations', the borrowed term ハルシネーション (harushinēshon) is used.

幻覚 (genkaku) is a hallucination, a perception without an external stimulus. 錯覚 (sakkaku) is an illusion, a misinterpretation of a real stimulus. For example, seeing a person who isn't there is 幻覚; mistaking a coat rack for a person is 錯覚.
A delusion (a false belief) is 妄想 (mōsō), not 幻覚. Hallucination is sensory; delusion is cognitive. Confusing them can lead to misunderstandings in medical contexts.
